mysql查询的1个存储过程,显示2个查询结果,怎么在PHP里把2个结果显示出来
mysql查询的1个存储过程,显示2个查询结果,怎么在PHP里把2个结果显示出来
------------------------------
mysql存储过程:
-------------------------------
begin
declare strSQL varchar(3000);
declare beginnum int;
declare strCount_s varchar(2000);
/*判断页数,如果是空或者0或者null默认第一页*/
if(PageIndex is null or PageIndex = '' or PageIndex = 0)
then
set PageIndex = 1;
end if;
/*判断每页显示数,如果是空或者0或者null默认第一条*/
if (SplitCount=0 or SplitCount='' or SplitCount is null)
then
set SplitCount = 1;
end if;
/*根据条件,查询所有数据集*/
set @beginnum = (PageIndex -1) * SplitCount;
set @strSQL = concat('select ', numtype, ' from ', tablename, ' where ', wheretype,' ' , OrderBy, ' limit ',@beginnum, ',', SplitCount);
PREPARE stmt from @strSQL;
execute stmt;
DEALLOCATE PREPARE stmt;
/*根据条件,查询总数据数量*/
set @strCount_s=concat('select count(1) as countnum from ', tablename,' where ', wheretype);
prepare select_rowscount from @strCount_s;
execute select_rowscount;
DEALLOCATE PREPARE select_rowscount;
end
MYSQL结果1: DEALLOCATE PREPARE stmt; 输出的所有查询数据
MYSQL结果2: DEALLOCATE PREPARE select_rowscount; 输出查询总数量

PHP存储过程类
----------------------------------------
/**

* 格式为ProduceName(para1, para2.....),
* 如果参数是字符请加单引号
* @return $resultnum 返回操作成功影响的行数
* @throws Exception 存储过程异常
*/
public static function RunProduce($produceAndParams)
{
global $_config;
if (!mysql_query("SET NAMES ".$_config['coding'], self::$_wdbConn)) {
throw new Exception("设置字符集".$_config['coding']."失败:".mysql_error());
}
if(!mysql_query('call '.$produceAndParams.';', self::$_wdbConn)) {
throw new Exception("调用存储过程失败:".mysql_error());
}
$resultNum = mysql_affected_rows(self::$_wdbConn);
return $resultNum;
}

php调用MySQL存储过程方法集合类型一:调用带输入、输出类型参数的方法view plainprint?$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 $returnValue; //输出来自存储过程中输出的变量 类型二:调用带多个输出类型和多个输入类型参数的方法view plainprint?$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.'
'; //输出来自存储过程中输出的变量 echo 'User id:'.$uId; //获取用户id 类型三:调用带返回结果集的方法view plainprint?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']; //输出数据集 } } catch ( Exception $e ) { echo $e; } 类型四:调用带返回多个结果集的方法(目前只能通过mysqli来实现~~~~~)view plainprint?//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);相关文章
