Type 1: Call a method with input and output type parameters

Copy code The code is as follows:

 $returnValue = '';
try {
 mysql_query ( "set @Return" );
 $spname = 'P__Test_GetInfo1';
 mysql_query ( "call $spname(@Return, '{$userId }', '{$pwd}')" ) or die ( "[$spname]Query failed:" . mysql_error () );
 $result_return = mysql_query ( "select @Return" );
 $row_return = mysql_fetch_row ( $result_return );
 $returnValue = $row_return [0];
} catch ( Exception $e ) {
 echo $e;
}
echo $returnValue; // The output comes from the variables output in the stored procedure 

Type 2: Call a method with multiple output types and multiple input type parameters

Copy code The code is as follows:

$userId = 0;
try{
 mysql_query("set @Message");
 mysql_query(" set @Id");
 mysql_query("call P__Test_Login(@Message, @Id, '{$userId}', '{$pwd}')", $conn) or die("Query failed:".mysql_error ());
 $result_mess = mysql_query("select @Message");
 $result_uid = mysql_query("select @Id");
 $row_mess = mysql_fetch_row($result_mess);
 $ row_uid = mysql_fetch_row($result_uid);
 $Proc_Error = $row_mess[0];
 $uId = $row_uid[0];
}
catch( Exception $e )
{
 echo $e;
}
echo 'proc return message:'$Proc_Error.'
'; //Output the variable output from the stored procedure
echo 'User id: '.$uId; //Get user id

Type 3: Call a method that returns a result set

Copy code The code is as follows:

try {
 $spname = 'P__Test_GetData';
 $query = mysql_query ( "call $spname()", $conn ) or die ( "[$spname]Query failed:".mysql_error() );
 while ( $row = mysql_fetch_array ( $query ) ) {
 echo $row ['ProvinceID'].'::'.$row ['ProvinceName']; //Output data set
 }

} catch ( Exception $e ) {
 echo $e;
}

Type 4: Calling a method that returns multiple result sets (currently only possible through mysqli~~)

Copy code The code is as follows :

//PHP
$rows = array (); 
$db = new mysqli($server,$user,$psd,$dbname); 
if ( mysqli_connect_errno()){ 
 $this->message('Can not connect to MySQL server'); 
} 
$db->query("SET NAMES UTF8"); 
$ db->query("SET @Message");
if($db->real_query("call P__Test_GetData2(@Message)")){ 
 do{ 
 if($result = $ db->store_result()){ 
 while ($row = $result->fetch_assoc()){ 
 array_push($rows, $row); 
 } }             $result-> ;close(); 
 } } 
 }while($db->next_result()); 
} 
$db->close(); 
print_r($rows); 
//Procedure 
……
select * from T1 where ……
select * from T2 where ……
……
