PHP连接MSSQL方法汇总_PHP

$conn=mssql_connect("实例名或者服务器IP","用户名","密码"); //测试连接 if($conn) { echo "连接成功"; }

mssql_select_db("dbname");

$rs = mssql_query("select top 1 id,username from tbname",$conn); // 或者直接执行update,insert等语句,可以不用为返回结果赋值 mssql_query("update tbname set username='niunv' where id=1");

echo mssql_num_rows($rs);

if($row=mssql_fetch_array($rs)) { $id = $row[0];//获取ID字段值 $username = $row[1];//获取username字段值 }

mssql_query("insert into tbname(username) values ('nv')",$conn); $rs = mssql_query("select @@IDENTITY as id",$conn); if($row=mssql_fetch_array($rs)) { echo $row[0]; }

mssql_free_result($rs);

mssql_close($conn);
