用mysql建一张名为Employee的表，ID、NAME、DISPLAY_NAME

并拿一个字段为例，写好增、删、改、查的语句，谢谢

CREATE TABLE `Employee` ( `ID` int( 10 ) unsigned NOT NULL auto_increment ,
`NAME` varchar( 32 ) NOT NULL ,
`DISPLAY_NAME` varchar( 32 ) NOT NULL ,
PRIMARY KEY ( `ID` ) )
//add
$name=$_POST['name'];
$displayname=$_POST['displayname'];
mysql_query("INSERT INTO Employee SET NAME='$name',DISPLAY_NAME='$displayname'");
//remove
$id=intval($_REQUEST['ID']);
mysql_query("DELETe FROM Employee WHERe ID='$id'");

//UPDATe
mysql_query("UPDATE Employee SET NAME='$name',DISPLAY_NAME='$displayname' WHERe ID='$id'");

//select

$res=mysql_query("select 8 from Employee");
while($row=mysql_fetch_array($res))
{
echo "ID=".$row['ID']." NAME=".$row['NAME']." DISPLAY=".$row['DISPLAY_NAME']."<br>";
}
