We engi-neer powerful solutions. Working closely with your product team, we can tailor switching and cir-cuit protection solutions that meet your application needs — cost effectively.Since our founding in 1920, there are few products we haven’t turned on, fewer industries that haven’t turned to us. With five ISO certified manufacturing locations and technical sales offices worldwide, Carling T echnologies now ranks among the world’s largest privately owned manufac-turers of hydraulic/magnetic circuit breakers, thermal circuit protectors, electrical switches and assemblies, power distribution centers and electronic control systems. In regard to circuit protec-tion, we lead the industry in delivering higher ratings in smaller packages. And what makes all our breakers especially attractive is their superior performance and reliability ––– both hallmarks of Carling T echnologies .Our Ground Fault Circuit Protection products are specifically designed for those applications that could benefit from having overload, short circuit & ground fault protection in a single package.The PB-Series and PD-Series Smartguard can be used to protect several different types of equipment.

[PB]-动态数据窗口〓创建动态数据窗口若要动态创建数据窗口，需要使用函数Create，该函数的语法如下：dw_1.Create(syntax{,errorbuffer})其中，dw_1是数据窗口控件的名称，该数据窗口控件要和新创建的数据窗口对象相关联。

syntax是用来描述创建数据窗口对象的确切语法的字符串。

errorburrer是可选项，用来保存创建数据窗口对象过程中发生的错误信息。

如果不指定该参数，就会在发生错误时显示一个错误信息的提示窗口。

如果创建成功该函数返回1，否则返回-1，如果参数为null则函数返回null。

由于Create函数成功创建数据窗口对象后，要改变dw_1数据窗口控件所关联的数据窗口对象，因此，需要重新为数据窗口设置事务对象(使用函数SetTransObject或者SetTrans)。

获取创建数据窗口的语法有多种方法，可以对相关的SQL语句使用SyntaxFromSQL函数，也可以使用对已经创建好的数据窗口对象使用LibraryExport函数。

因为创建数据窗口的语法比较复杂，即使使用了LibraryExport输出已有数据窗口对象的语法，操作起来也相当费劲。

所以，更为通用的是前面一种方法。

这种方法配合一定的编程技巧，让用户指定要创建的数据窗口对象的SQL语句，使用户有更多的自由和选择。

使用这种方法，肯定用到函数SyntaxFromSQL，它的语法是：transaction.SyntaxFromSQL(SQLselect,presetation,err)其中，transaction是事务对象的名称，该事务对象必须正确地设置了相关参数，并且和数据库建立了联结。

SQLselect是用来创建数据窗口的SQL语句，为String 类型。

presentation是要创建的数据窗口对象的显示风格，为String类型。

简单的格式是：Style(Type=presentationstyle)其中Style和Type都是保留字，presentationstyle的取值有Tabular，Grid，Form，Graph，Group，Label和Nup，其中Tabular是缺省类型。

pb modify用法"pb modify"是一个命令行工具，通常用于修改Protobuf （Protocol Buffers）文件中的消息定义。

在使用"pb modify"命令时，你需要指定要修改的消息名称和要进行的修改操作，例如添加新字段、修改字段类型等。

下面我将从多个角度来解释"pb modify"的用法。

1. 添加新字段：通过"pb modify"命令，你可以向现有的消息定义中添加新的字段。

这可以通过指定字段名称、字段类型和其他必要的属性来完成。

例如，如果你想要向一个名为"User"的消息中添加一个新的"email"字段，你可以使用以下命令：pb modify User --add=email:string.2. 修改字段类型：有时候你可能需要修改现有字段的数据类型，"pb modify"命令也可以帮助你实现这一目的。

例如，如果你需要将一个整数类型的字段改为字符串类型，你可以使用以下命令：pb modify User --type=age:string.3. 删除字段：如果你需要从消息定义中移除某个字段，也可以通过"pb modify"命令来实现。

例如，如果你想要删除"User"消息中的"address"字段，可以使用以下命令：pb modify User --remove=address.4. 修改字段属性：除了修改字段类型外，你还可以使用"pb modify"命令来修改字段的其他属性，比如默认值、是否必填等。

例如，如果你需要将"User"消息中的"age"字段的默认值修改为"18"，可以使用以下命令：pb modify User --default=age:18。

pb的ddlb技巧在数据库管理中，DDL（数据定义语言）用于定义数据库的结构，其中包括创建、修改和删除数据库对象。

而PB（PowerBuilder）是一种集成开发环境，用于构建企业级应用程序。

在PB中操作数据库时，可以使用DDL语句来创建、修改和删除数据库对象。

以下是一些PB中使用DDL的技巧：1. 创建表：在PB中，可以使用CREATE TABLE语句来创建数据库表。

可以指定表的名称、列的数据类型、约束等信息。

例如：CREATE TABLE employee (。

emp_id INT PRIMARY KEY,。

emp_name VARCHAR(50),。

emp_salary DECIMAL(10,2)。

);2. 修改表：如果需要修改已存在的表结构，可以使用ALTER TABLE语句。

例如，添加新的列或修改列的数据类型：ALTER TABLE employee.ADD emp_department VARCHAR(50);3. 删除表：如果需要删除已存在的表，可以使用DROP TABLE 语句。

例如：DROP TABLE employee;4. 创建索引：在PB中，可以使用CREATE INDEX语句来创建索引，以提高查询性能。

例如：CREATE INDEX idx_emp_name ON employee (emp_name);5. 删除索引：如果不再需要某个索引，可以使用DROP INDEX 语句来删除它。

例如：DROP INDEX idx_emp_name ON employee;6. 使用事务，在执行DDL语句时，建议使用事务来确保数据的一致性。

可以使用BEGIN TRANSACTION和COMMIT TRANSACTION语句来控制事务的范围。

7. 错误处理，在执行DDL语句时，需要考虑可能出现的错误情况。

可以使用TRY...CATCH块来捕获并处理异常情况，以确保程序的稳定性。

总之，在PB中使用DDL语句需要谨慎对待，确保在操作数据库结构时不会造成数据丢失或不一致。
