Question

在使用phpmyadmin获取结果

运行以下查询时

SET @rownr=0;
SELECT TVGD.video_id,TVM.Video_Title,@rownr:=@rownr+1 AS `Order`,'0' As Min_Pass_Mark
FROM tbl_video_group_details TVGD,tbl_Video_Master TVM WHERE TVGD.video_id=TVM.id AND TVGD.group_id='23'

但是使用mysql_query（）函数

运行时，同样会返回语法错误

Answer 1

mysql_query()不支持多个语句，例如1）SET @rownr=0; 2）您的查询可以重写您的查询，如下所示

SELECT 
  TVGD.video_id,
  TVM.Video_Title,
  @rownr := @rownr + 1 AS `Order`,
  '0' AS Min_Pass_Mark 
FROM
  tbl_video_group_details TVGD,
  tbl_Video_Master TVM ,
  (SELECT @rownr := 0) t
WHERE TVGD.video_id = TVM.id 
  AND TVGD.group_id = '23'

或者您可以使用支持多个语句的mysqli::multi_query

运行mysql_query（）时直接phpmyadmin正常运行错误
