Question

我创建了一个使用mssql计算问题集的过程。我在下面发布该查询。现在我想将以下查询转换为mysql，但它返回错误。请帮我修复此错误..

我的部分查询就在这里......

     select trainPrecent1 = (select distinct(fldprecentage) from precentage  where    fldgroup='Training' and fldset='First'),
     trainPrecent2 = (select distinct(fldprecentage) from precentage where fldgroup='Training' and fldset='Second'),
     agentPrecent1 = (select distinct(fldprecentage) from precentage where fldgroup='Agent on floor' and fldset='First'),
     agentPrecent2 = (select distinct(fldprecentage) from precentage where fldgroup='Agent on floor' and fldset='Second'), 
     superPrecent1 = (select distinct(fldprecentage) from precentage where fldgroup='Supervisor on floor' and fldset='First'), 
     superPrecent2 = (select distinct(fldprecentage) from precentage where fldgroup='Supervisor on floor' and fldset='Second')

现在收到以下错误...

 "unknown column name "trainPrecent1" in fielelist...

请帮我解决此错误....
