PHP连接MS SQL数据库代码方法

--------------------------------------------------------------------------------

1.安装SQL服务器并添加PHP的MSSQL扩展

2.使用以下代码连接并测试

$myServer = localhost; //主机

$myUser = sa; //用户名

$myPass = password; //密码

$myDB = Northwind; //MSSQL库名

$s = @mssql_connect($myServer, $myUser, $myPass)

or die(Couldnt connect to SQL Server on $myServer);

$d = @mssql_select_db($myDB, $s)

or die(Couldnt open database $myDB);

$query = SELECT TitleOfCourtesy+ +FirstName+ +LastName AS Employee ;

$query .= FROM Employees ;

$query .= WHERE Country=USA AND Left(HomePhone, 5) = (206);

$result = mssql_query($query);

$numRows = mssql_num_rows($result);

echo

. $numRows . Row . ($numRows == 1 ? : s) . Returned

while($row = mssql_fetch_array($result))

{

echo

}
