Question

我正在以递归方式处理下面的代码到同一个表但是收到错误

*Column 'checkinout.USERID' is invalid in the select list because it is not contained in either an aggregate function or the GROUP BY clause.*

*Column 'checkinout.CHECKTIME' is invalid in the select list because it is not contained in either an aggregate function or the GROUP BY clause.*

SELECT CONVERT(VARCHAR,checktime, 106) gateDate, CONVERT(VARCHAR,checktime, 106) gateIn
,(
    SELECT TOP 1 CONVERT(VARCHAR(5),CH001.checktime, 108) 
    FROM checkinout CH001
    WHERE checktype ='I' 
        AND ch001.userid= mm001.userid   
        AND 
        (CONVERT(VARCHAR, CH001.checktime, 112) =CONVERT(VARCHAR, MM001.checktime, 112))
) timeIn

FROM  checkinout MM001
WHERE userid=@empid

Answer 1

SELECT CONVERT(VARCHAR,checktime, 106) gateDate, CONVERT(VARCHAR,checktime, 106) gateIn
,(
    SELECT TOP 1 CONVERT(VARCHAR(5),CH001.checktime, 108) 
    FROM checkinout CH001
    WHERE checktype ='I' 
        AND ch001.userid= mm001.userid   
        AND 
        (CONVERT(VARCHAR, CH001.checktime, 112) =CONVERT(VARCHAR, MM001.checktime, 112))
) timeIn

FROM  checkinout MM001
WHERE userid=@empid
GROUP BY checkinout.USERID, checkinout.CHECKTIME
