php mysql查询语句当使用PHP和MySQL进行查询时，你可以使用以下步骤来执行查询语句：1. 连接到MySQL数据库：使用PHP的MySQL扩展或MySQLi扩展连接到MySQL数据库。
你需要提供数据库的主机名、用户名、密码和数据库名称。
```php<?php$servername = "localhost"; // 数据库主机名$username = "username"; // 数据库用户名$password = "password"; // 数据库密码$dbname = "database"; // 数据库名称// 使用MySQL扩展连接数据库$conn = mysql_connect($servername, $username, $password);if (!$conn) {die("连接失败: " . mysql_error());}// 选择数据库mysql_select_db($dbname, $conn);>```2. 执行查询语句：使用`mysql_query()`函数执行查询语句。
你需要提供查询语句作为参数。
```php<?php// 执行查询语句$sql = "SELECT FROM table_name";$result = mysql_query($sql, $conn);// 检查是否有结果返回if (!$result) {die("查询失败: " . mysql_error());}>```3. 处理查询结果：你可以使用`mysql_fetch_assoc()`函数来获取结果集中的每一行数据，并将其存储在关联数组中。
你可以遍历数组来处理每一行数据。
```php<?php// 处理查询结果while ($row = mysql_fetch_assoc($result)) {// 输出每一行数据echo "ID: " . $row["id"] . ", Name: " . $row["name"] . "<br>";}>```4. 关闭数据库连接：在完成查询操作后，记得关闭数据库连接。
MySQL数据库管理外文翻译文献(文档含中英文对照即英文原文和中文翻译)原文：Management Center of MySQLAuthors: Lauderdale, JohnTsang, Danny H. K.Baciu, GeorgeIssue Date: 2006Citation: Proceedings of IEEE Visual '96, Melbourne, Australia, February 2006, p. 447-458Database (sometimes spelled database) is also called an electronic database, referring to any collections of data, or information, that is specially organized for rapid search and retrieval by a computer. Databases are structured to facilitate the storage, retrieval, modification and deletion of data in conjunction with various data-processing operations.Database can be stored on magnetic disk or tape, optical disk, or some other secondary storage device.A database consists of a file or a set of files. The information in the these files may be broken down into records, each of which consists of one or more fields are the basic units of data storage, and each field typically contains information pertaining to one aspect or attribute of the entity described by the database. Using keywords and various sorting commands, users can rapidly search, rearrange, group, and select the fields in many records to retrieve or create reports on particular aggregates of data.Database records and files must be organized to allow retrieval of the information. Early system were arranged sequentially (i.e., alphabetically, numerically, or chronologically); the development of direct-access storage devices made possible random access to data via indexes. Queries are the main way users retrieve database information. Typically the user provides a string of characters, and the computer searches the database for a corresponding sequence and provides the source materials in which those characters appear. A user can request, for example, all records in which the content of the field for a person’s last name is the word Smith.In flat databases, records are organized according to a simple list of entities; many simple databases for personal computers are flat in structure. The records in hierarchical databases are organized in a treelike structure, with each level of records branching off into a set of smaller categories. Unlike hierarchical databases, which provide single links between sets of records at different levels, network databases create multiple linkages between sets by placing links, or pointers, to one set of records in another; the speed and versatility of network databases have led to their wide use in business. Relational databases are used where associations among files or records cannot be expressed by links; a simple flat list becomes one table, or “relation”, and multiple relations can be mathematically associated to yield desired information. Object-oriented databases store and manipulate more complex data structures, called “objects”, which are organized into hierarchical classes that may inherit properties from classes higher in the chain; this database structure is the most flexible and adaptable.The information in many databases consists of natural-language texts of documents; Small databases can be used by individuals at home. These and larger databases have become increasingly important in business life. Typical commercial applications include airline reservations, production management, medical records in hospitals, and legal records of insurance companies. The largest databases are usually maintained by governmental agencies, business organizations, and universities. These databases may contain texts of such materialsas catalogs of various kinds. Reference databases contain bibliographies or indexes that serve as guides to the location of information in books, periodicals, and other published literature. Thousands of these publicly accessible databases now exist, covering topics ranging from law, medicine, and engineering to news and current events, games, classified advertisements, and instructional courses. Professionals such as scientists, doctors, lawyers, financial analysts, stockbrokers, and researchers of all types increasingly rely on these databases for quick, selective access to large volumes of information.DBMS Structuring TechniquesSequential, direct, and other file processing approaches are used to organize and structure data in single files. But a DBMS is able to integrate data elements from several files to answer specific user inquiries for information. That is, the DBMS is able to structure and tie together the logically related data from several large files.Logical Structures. Identifying these logical relationships is a job of the data administrator. A data definition language is used for this purpose. The DBMS may then employ one of the following logical structuring techniques during storage, access, and retrieval operations.List structures. In this logical approach, records are linked together by the use of pointers.A pointer is a data item in one record that identifies the storage location of another logically related record. Records in a customer master file, for example, will contain the name and address of each customer, and each record in this file is identified by an account number. During an accounting period, a customer may buy a number of items on different days. Thus, the company may maintain an invoice file to reflect these transactions. A list structure could be used in this situation to show the unpaid invoices at any given time. Each record in the customer in the invoice file includes a field, it pointed to the location of the first invoice record in invoice file, this invoice record, in turn, would be linked to next invoices for the customer. The last invoice in the chain would be identified by the use of a special character as a pointer.Hierarchical (tree) structures. In this logical approach, data units are structured in multiple levels that graphically resemble an “upside down” tree with the root at the top and the branches formed below. There’s a superior-subordinate relationship in a hierarchical (tree) structure. Below the single-root data component are subordinate elements or nodes, in turn, each element or branch in this structure below the root has only a single owner. Thus, a customer owns an invoice, and the invoice has subordinate items. The branches in a tree structure are not connected.Network Structures. Unlike the tree approach, which does not permit the connection ofbranches, the network structure permits the connection of the nodes in a multidirectional manner. Thus, each node may have several owners and may, in turn, own any number of other data units. Data management software permits the extraction of the needed information from such a structure by beginning with any record in a file.Relational structures. A relational structure is made up of many tables. The data are stored in the form of “relations” in these tables. This is a relatively new database structuring app roach that’s expected to be widely implemented in the future.Physical Structures. People visualize or structure data in logical ways for their own purposes. Thus, records R1 and R2 may always be logically linked and processed in sequence in one particular application. However, in a computer system it’s quite possible that these records that are logically contiguous in one application are not physically stored together. Rather, the physical structure of the records in media and hardware may depend not only on the I/O and storage devices and storage techniques used, but also on the different logical relationships that users may assign to the data found in R1 and R2. For example, R1 and R2 may be records of credit customers who have shipments send to the same block in the same city every 2 weeks. From the shipping department manager’s perspective, then, R1 and R2 are sequential entries on a geographically organized shipping report. But in the A/R application, the customers represented by R1 and R2 may be identified, and their accounts may be processed, according to their account numbers which are widely separated. In short, then, the physical location of the stored records in many computer-based information systems is invisible to users.Database Management Features of MySQLMySQL includes many features that make the database easier to manage. We’ve divided the discussion in this section into three categories: MySQL Enterprise Manager, add-on packs, backup and recovery.1. MySQL Enterprise ManagerAs part of Database Server, MySQL provides the MySQL Enterprise Manager (EM), a database management tool framework with a graphical interface used to manage database users, instances, and features (such as replication) that can provide additional information about the MySQL environment.Prior to the MySQL8i database, the EM software had to be installed on Windows 95/98 or NT-based systems and each repository could be accessed by only a single database manager at a time. Now you can use EM from a browser or load it onto Windows 95/98/2000 or NT-based systems. Multiple database administrators can access the EM repository at the same time. In the EM repository for MySQL9i, the super administrator can define servicesthat should be displayed on other administrators’ console s, and management regions can be set up.2. Add-on packsSeveral optional add-on packs are available for MySQL, as described in the following sections. In addition to these database-management packs, management packs are available for MySQL Applications and for SAP R/3.(1)standard Management PackThe Standard Management Pack for MySQL provides tools for the management of small MySQL databases (e.g., MySQL Server/Standard Edition). Features include support for performance monitoring of database contention, I/O, load, memory use and instance, session analysis, index tuning, and change investigation and tracking.(2)Diagnostics PackYou can use the Diagnostic Pack to monitor, diagnose, and maintain the health of Enterprise Edition databases, operating systems, and applications. With both historical and real-time analysis, it can automatically avoid problems before they occur. The pack also provides capacity planning features that help you plan and track future system-resource requirements.(3)Tuning PackWith the Tuning Pack, you can optimise system performance by identifying and tuning Enterprise Edition databases and application bottlenecks such as inefficient SQL, poor data design, and the improper use of system resources. The pack can proactively discover tuning opportunities and automatically generate the analysis and required changes to tune the systems.(4)Change Management PackThe Change Management Pack helps eliminate errors and avoid loss of data when upgrading Enterprise Edition databases to support new applications. It can analysis impact and complex dependencies associated with application changes and automatically perform database upgrades. Users can use the easy-to-use wizards that teach the systematic steps necessary to upgrade.(5)AvailabilityMySQL Enterprise Manager can be used for managing MySQL Standard Edition or Enterprise Edition. To Enterprise Edition, additional functionality is provided by separate Diagnostics, Tuning, and Change Management Packs.3. Backup and RecoveryAs every database administrator knows, backing up a database is a rather mundane butnecessary task. An improper backup makes recovery difficult, if not impossible. Unfortunately, people often realize the extreme importance of this everyday task only when it is too late –usually after losing business-critical data due to a failure of a related system.The following sections describe some products and techniques for performing database backup operations.(1)Recovery ManagerTypical backups include complete database backups (the most common type), database backups, control file backups. Previously, MySQL’s Enterprise Backup Utility (EBU) provided a similar solution on some platforms. However, RMAN, with its Recovery Catalog stored in an MySQL database, provides a much more complete solution. RMAN can automatically locate, back up, restore, and recover databases, control files, and archived redo logs. RMAN for MySQL9i can restart backups and restores and implement recovery window policies when backups expire. The MySQL Enterprise Manager Backup Manager provides a GUI-based interface to RMAN.(2)Incremental backup and recoveryRMAN can perform incremental backups of Enterprise Edition databases. Incremental backups back up only the blocks modified since the last backup of a datafile, tablespace, or database; thus, they’re smaller and faster than complete backups. RMAN can also perform point-in-time recovery, which allows the recovery of data until just prior to a undesirable event.(3)Legato Storage ManagerVarious media-management software vendors support RMAN. MySQL bundles Legato Storage Manager with MySQL to provide media-management services, including the tracking of tape volumes, for up to four devices. RMAN interfaces automatically with the media-management software to request the mounting of tapes as needed for backup and recovery operations.(4)AvailabilityWhile basic recovery facilities are available for both MySQL Standard Edition and Enterprise Edition, incremental backups have typically been limited to Enterprise Edition. Choosing between MySQL and SQL ServerI have to decide between using the MySQL database and its development system, Microsoft SQL Server with Visual Studio. This choice will guide our future Web projects. What are the strong points of each of these combinations and what are the negatives?Lori: Making your decision will depend on what you already have. For instance, if you want to implement a Web-based database application and you are a Windows-only shop, SQLServer and the Visual Studio package would be fine. But the MySQL solution would be better with mixed platforms.There are other things to consider, such as what extras you get and what skills are required. WebDB is a content management and development tool that can be used by content creators, database administrators, and developers without any programming experience. WebDB is a browser-based tool that helps ease content creation and provides monitoring and maintenance tools. This is a good solution for organizations already using MySQL. MySQL also scales better than SQL Server, but you will need to have a competent MySQL administrator on hand.The SQL Sever/Visual Studio approach is more difficult to use and requires an experienced object-oriented programmer or some extensive training. However, you do get a fistful of development tools with Visual Studio: Visual Basic, Visual C++, and Visual InterDev for only $1,619. Plus, you will have to add the cost of the SQL Server, which will run you $1,999 for 10 clients or $3,999 for 25 clients-a less expensive solution than MySQL’s.MySQL also has a package solution that starts at $6,767, depending on the platform selected. The suite includes not only WebDB and MySQL8i but also other tools for development such as the MySQL application server, JDeveloper, and Workplace Templates, and the suite runs on more platforms than the Microsoft solution does. This can be a good solution if you are a start-up or a small to midsize business. Buying these tools in a package is less costly than purchasing them individually.Much depends on your skill level, hardware resources, and budget. I hope this helps in your decision-making.Brooks: I totally agree that this decision depends in large part on what infrastructure and expertise you already have. If the decision is hard, you need to fi gure out who’s going to be doing the work and what your priorities are.These two products have different approaches, and they reflect the different personalities of the two vendors. In general, MySQL products are designed for very professional development efforts by top-notch programmers and project leaders. The learning period is fairly long, and the solution is pricey; but if you stick it out you will ultimately have greater scalability and greater reliability.If your project has tight deadlines and you don’t have the time or money to hire a team of very expensive, very experienced developers, you may find that the MySQL solution is an easy way to get yourself in trouble. There’s nothing worse than a poorly developed MySQL application.What Microsoft off ers is a solution that’s aimed at rapid development and low-cost implementation. The tools are cheaper, the servers you’ll run it on are cheaper, and the developers you need will be cheaper. Choosing SQL Sever and Visual Studio is an excellent way to start fast.Of course, there are trade-offs. The key problem I have with Visual Studio and SQL Server is that you’ll be tied to Microsoft operating systems and Intel hardware. If the day comes when you need to support hundreds of thousands of users, you really don’t have anywhere to go other than buying hundreds of servers, which is a management nightmare.If you go with the Microsoft approach, it sounds like you may not need more than Visual Interdev. If you already know that you’re going to be developing Activ eX components in Visual Basic or Visual C++, that’s warning sign that maybe you should look at the MySQL solution more closely.MySQL数据库管理中心数据库（有时拼成database）也称为电子数据库，是指由计算机特别组织的快速查找和检索的任意的数据或信息集合。
连接mysql的方法连接MySQL的方法主要有以下几种：1. 使用MySQL命令行工具连接：在命令行中输入`mysql -u 用户名-p`，然后输入密码即可连接到MySQL服务器。
2. 使用MySQL提供的图形化界面工具连接：MySQL提供了一些图形化界面工具，如MySQL Workbench、phpMyAdmin等，可以通过它们来连接MySQL 服务器。
3. 使用编程语言的MySQL驱动连接：各种编程语言都提供了与MySQL交互的驱动程序，可以通过编写代码来连接MySQL服务器。
例如，在Java中可以使用JDBC驱动，Python中可以使用PyMySQL、mysql-connector-python 等驱动。
下面是一个使用Python的PyMySQL模块连接MySQL的例子：import pymysql# 连接数据库conn = pymysql.connect(host='localhost', user='root',password='123456', database='test')# 创建游标对象cursor = conn.cursor()# 执行SQL语句sql = "SELECT * FROM user"cursor.execute(sql)# 获取结果result = cursor.fetchall()for row in result:print(row)# 关闭游标和连接cursor.close()conn.close()这是一个简单的连接和执行SQL语句的例子，具体的连接参数和SQL语句根据实际情况进行调整。
PHP+MySQL数据库编程的步骤第⼀步：PHP连接MySQL服务器第⼆步：选择当前要操作的数据库第三步：设置请求或返回的数据的字符集第四步：执⾏各种SQL语句。

原文：Getting PHP to Talk to MySQlNow that you’re comfortable using the MySQL client tools to manipulate data in the database, you can begin using PHP to display and modify data from the database. PHP has standard functions for working with the databas e.First, we’re going to discuss PHP’s built-in database functions. We’ll also show you how to use the The PHP Extension and Application Repository (PEAR) databasefunctions that provide the ability to use the same functions to access any supported database. This type of flexibility comes from a process called abstraction. In programming interfaces, abstraction simplifies a complex interaction. It works by removing any nonessential parts of the interaction, allowing you to concentrate on the important pa rts. PEAR’s DB classes are one such database interface abstraction. The information you need to log into a database is reduced to the bare minimum. This standard format allows you to interact with MySQL, as well as other databases using the same functions. Similarly, other MySQL-specific functions are replaced with generic ones that know how to talk to many databases. For example, theMySQL-specific connect function is:mysql_connect($db_host, $db_username, $db_password);versus PEAR’s DB connect function:$connection =DB::connect("mysql://$db_username:$db_password@$db_host/$db_database");The same basic information is present in both commands, but the PEAR function also specifies the type of databases to which to connect. You can connect to MySQL or o ther supported databases. We’ll discuss both connection methods in detail.In this chapter, you’ll learn how to connect to a MySQL server fromPHP, how to use PHP to access and retrieve stored data, and how to correctly display information to the user.1 The ProcessThe basic steps of performing a query, whether using the mysql command-line tool or PHP, are the same:• Connect to the database.• Select the database to use.• Build a SELECT statement.• Perform the query.• Display the results.We’l l walk through each of these steps for both plain PHP and PEAR functions.2 ResourcesWhen connecting to a MySQL database, you will use two new resources. The first is the link identifier that holds all of the information necessary to connect to the database for an active connection. The other resource is the results resource. It contains all information required to retrieve results from an active database query’s result set. You’ll be creating and assigning both resources in this chapter.3 Querying the Database with PHP FunctionsIn this section, we introduce how to connect to a MySQL database with PHP. It’s quite simple, and we’ll begin shortly with examples, but we should talk briefly about what actually happens. When you try connecting to a MySQL database, the MySQL server authenticates you based on your username and password. PHP handles connecting to the database for you, and it allows you to start performing queries and gathering data immediately.As in Chapter 8, we’ll need the same pieces of information to connect to the database: • The IP address of the database server• The name of the database• The username• The passwordBefore moving on, make sure you can log into your database using the MySQL command-line client.4 Including Database Login DetailsYou’re going to create a file to hold the information for logging into MySQL. Storing this information in a file you include is recommended. If you change the database password, there is only one place that you need to change it, regardless of how many PHP files you have that access the database.You don’t have to worry about anyone directly viewing the file and getting your database login details. The file, if requested by itself, is processed as a PHP file and returns a blank page.5 Troubleshooting connection errorsOne error you may get is:Fatal error: Call to undefined functionmysql_connect( ) in C:\Program Files\ApacheSoftware Foundation\Apache2.2\htdocs\db_test.php on line 4This error occurs because PHP 5.x for Windows was downloaded, and MySQL support was not included by default. To fix this error, copy the php_mysql.dll file from the ext/ directory of the PHP ZIP file to C:\php, and then C:\WINDOWS\php.ini.Make sure there are two lines that are not commented out by a semicolon (;) at the beginning of the line like these:extension_dir = "c:/PHP/ext/"extension=php_mysql.dllThis will change the extension to include the directory to C:/php and include the MySQL extension, respectively. You can use the Search function of your text editorto check whether the lines are already there and just need to be uncommented, or whether they need to be added completely.You’ll need to restart Apache, and then MySQL support will be enabled.6 Selecting the DatabaseNow th at you’re connected, the next step is to select which database to use with the mysql_select_db command. It takes two parameters: the database name and,optionally, the database connection. If you don’t specify the database connection, the default is the connection from the last mysql_connect:// Select the database$db_select=mysql_select_db($db_database);if (!$db_select){die ("Could not select the database: <br />". mysql_error( ));}Again, it’s good practice to check for an error and display it every time you access the database.Now that you’ve got a good database connection, you’re ready to execute your SQL query.7 Building the SQL SELECT QueryBuilding a SQL query is as easy as setting a variable to the string that is your SQL query. Of co urse, you’ll need to use a valid SQL query, or MySQL returns with an error when you execute the query. The variable name $query is used since the name reflects its purpose, but you can choose anything you’d like for a variable name. The SQL query in this example is SELECT * FROM books.8 Executing the QueryTo have the database execute the query, use the mysql_query function. It takes two parameters—the query and, optionally, the database link—and returns the result. Save a link to the results in a variable called, you guessed it, $result! This is also a good place to check the return code from mysql_query to make sure that there were no errors in the query string or the database connection by verifying that $result is not FALSE:When the database executes the query, all of the results forma result set. These results correspond to the rows that you saw upon doing a query using the mysql command-line client. To display them, you process each row, one at a time.9 Fetching and DisplayingUse mysql_fetch_row to get the rows from the result set. Its syntax is:array mysql_fetch_row ( resource $result);It takes the result you stored in $result fromthe query as a parameter. It returns one row at a time from the query until there are no more rows, and then it returns FALSE. Therefore, you do a loop on the result of mysql_fetch_row and define some code to display each row:The columns of the result row are stored in the array and can be accessed one at a time. The variable $result_row accesses the second attribute (as defined in the query’s column order or the column order of the table if SELECT * is used) in the result row.10 Fetch typesThis is not the only way to fetch the results. Using mysql_fetch_array, PHP can place the results into an array in one step. It takes a result as its first parameter, and the way to bind the results as an optional second parameter. If MYSQL_ASSOC is specified, the results are indexed in an array based on their column names in the query. If MYSQL_NUM is specified, then the number starting at zero accesses the results. The default value, MYSQL_BOTH, returns a result array with both types. Themysql_fetch_assoc is an alternative to supplying the MYSQL_ASSOC argument.11 Closing the ConnectionAs a rule of thumb, you always want to close a connection to a database when you’redone using it. Closing a database with mysql_close will tell PHP and MySQL that you no longer will be using the connection, and will free any resources and memory allocated to it:mysql_close($connection)12 InstallingPEAR uses a Package Manager that oversees which PEAR features you install.Whether you need to install the Package Manager depends on which version of PHP you installed. If you’re running PHP 4.3.0 or newer, it’s already installed. If you’rerunning PHP 5.0, PEAR has been split out into a separate package. The DBpackage that you’re interested in is optional but installed by default with the Package Manager. So if you have the Package Manager, you’re all set.译文：通过PHP访问MySQL现在你已经可以熟练地使用MySQL客户端软件来操作数据库里的数据，我们也可以开始学习如何使用PHP来显示和修改数据库里的数据了。
