需要帮助“关键字GROUP附近的语法不正确”

Question

I don't know what I am doing wrong. I keep getting incorrect syntax error, it seems like I correct one, then the next line popup. Right now I am getting a "Incorrect syntax near keyword GROUP. I have had a couple of version of my issues on this site. I really appreciate the help so far. I just need that boost to get this report working. Anyone know of any good classes in Minnesota for sql. The books cover the basics, I need the complex sql class.

SELECT fgc, sum(Totpay) as Totpay, Sum(TotChg) as TotChg
from
(                     
    SELECT fgc, sum(pay) as TotPay, 0 as TotChg
    from 
    (
        SELECT fgc, pay,

You are not using alias for inline queries. Following not giving me any syntax error.

        SELECT fgc, sum(Totpay) as Totpay, Sum(TotChg) as TotChg
        from
        (                     
        SELECT fgc, sum(pay) as TotPay, 0 as TotChg
        from 
            (SELECT fgc, pay,
                CASE 
                WHEN  [date]<= 30 THEN 'pmt 0-30'      
                WHEN [date]> 30 AND [date] <= 60 THEN 'pmt 30-60'
                WHEN [date]> 61 AND [date] <= 90 THEN 'pmt 61-90'
                WHEN [date]> 91 AND [date] <= 120 THEN 'pmt 91-120'
                WHEN [date]> 121 AND [date] <= 150 THEN 'pmt 121-150'
                WHEN [date]> 151 AND [date] <= 180 THEN 'pmt 151-180'
                ELSE 'pmt 181+' 
                END
            FROM @Pay 
            GROUP BY fgc 

            UNION

            SELECT fgc, 0 as TotPay, sum(chg) as TotChg
            from
                (SELECT fgc, chg,
                    CASE 
                    WHEN [date]<= 30 THEN 'charge 0-30'      
                    WHEN [date]> 30 AND [date] <= 60 THEN 'charge 30-60' 
                    WHEN [date]> 61 AND [date] <= 90 THEN 'charge 61-90'
                    WHEN [date]> 91 AND [date] <= 120 THEN 'charge 91-120'
                    WHEN [date]> 121 AND [date] <= 150 THEN 'charge 121-150'
                    WHEN [date]> 151 AND [date] <= 180 THEN 'charge 151-180'
                    ELSE 'charge 181+' 
                    END
                 FROM @Chg) as innerTable2
             GROUP BY fgc 
            ) As innertable1
        GROUP BY fgc
    )  as outerTable

Answer 2

Basically, GROUP BY keyword is used in case using aggregate function, and in order to use it, you must group all column with out using aggregate function on it.

For eg: instead GROUP BY fgc, should use GROUP BY (fgc, pay, aliasName).

Change:

SELECT fgc, pay, CASE WHEN [date]<= 30 THEN 'pmt 0-30'
WHEN [date]> 30 AND [date] <= 60 THEN 'pmt 30-60' WHEN [date]> 61 AND [date] <= 90 THEN 'pmt 61-90' WHEN [date]> 91 AND [date] <= 120 THEN 'pmt 91-120' WHEN [date]> 121 AND [date] <= 150 THEN 'pmt 121-150' WHEN [date]> 151 AND [date] <= 180 THEN 'pmt 151-180' ELSE 'pmt 181+' END FROM @Pay GROUP BY fgc

into

SELECT fgc, pay, CASE WHEN [date]<= 30 THEN 'pmt 0-30'
WHEN [date]> 30 AND [date] <= 60 THEN 'pmt 30-60' WHEN [date]> 61 AND [date] <= 90 THEN 'pmt 61-90' WHEN [date]> 91 AND [date] <= 120 THEN 'pmt 91-120' WHEN [date]> 121 AND [date] <= 150 THEN 'pmt 121-150' WHEN [date]> 151 AND [date] <= 180 THEN 'pmt 151-180' ELSE 'pmt 181+' END as alias FROM @Pay GROUP BY (fgc, pay, alias)

Hope this help.

P/S: tks Gabe for correcting me.
