php下使用以下代码连接并测试

<?php     

$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("Couldn't connect to SQL Server on $myServer");     

$d = @mssql_select_db($myDB, $s)     
or die("Couldn't 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 "<h1>" . $numRows . " Row" . ($numRows == 1 ? "" : "s") . " Returned </h1>";     

while($row = mssql_fetch_array($result))     
{     
echo "<li>" . $row["Employee"] . "</li>";     
}
