Aggregate in an update statement

  • Hi guys,

    I'm getting the following error message 'An aggregate may not appear in the set list of an

    UPDATE statement' What is the proper way to carry out an update on aggregates?

    My code is below:

    t1.TotalTest1 = coalesce(Sum(t2.AmountTest1), 0.00),

    t1.TotalTest2 = coalesce(Sum(t2.AmountTest2), 0.00),

    t1.TotalTest3 = coalesce(Sum(t2.AmountTest3), 0.00),

    t1.TotalTest4 = coalesce(Sum(t2.AmountTest4), 0.00),

    from #tbl_CHA t1

    inner join

    (

    select

    tt1. AmountTest1,

    tt1. AmountTest2,

    tt1. AmountTest3,

    tt1. AmountTest4

    from Test.dbo.Posted tt1 (nolock)

    union all

    select

    tt1. AmountTest1,

    tt1. AmountTest2,

    tt1. AmountTest3,

    tt1. AmountTest4

    from Test.dbo.Pended tt1 (nolock)

    union all

    select

    tt1. AmountTest1,

    tt1. AmountTest2,

    tt1. AmountTest3,

    tt1. AmountTest4

    from Test.dbo.PrePay tt1) as t2 on

    t1.Id = left(t2.Id_1, 15) + right(t2.Id_1, 2)

  • You're missing some part of the statement, I'll assume it's just the UPDATE part at the top.

    Here's how you do it:

    UPDATE t1

    SET t1.TotalTest1 = coalesce(t2.SumAmountTest1, 0.00)

    ,t1.TotalTest2 = coalesce(t2.SumAmountTest2, 0.00)

    ,t1.TotalTest3 = coalesce(t2.SumAmountTest3, 0.00)

    ,t1.TotalTest4 = coalesce(t2.SumAmountTest4, 0.00)

    FROM #tbl_CHA t1

    INNER JOIN (

    SELECT Sum(t2.AmountTest1) AS SumAmountTest1,

    Sum(t2.AmountTest2) AS SumAmountTest2,

    Sum(t2.AmountTest3) AS SumAmountTest3,

    Sum(t2.AmountTest4) AS SumAmountTest4

    FROM (

    SELECT tt1.AmountTest1

    ,tt1.AmountTest2

    ,tt1.AmountTest3

    ,tt1.AmountTest4

    FROM Test.dbo.Posted tt1 --(NOLOCK) get rid of NOLOCK!

    UNION ALL

    SELECT tt1.AmountTest1

    ,tt1.AmountTest2

    ,tt1.AmountTest3

    ,tt1.AmountTest4

    FROM Test.dbo.Pended tt1 --(NOLOCK) get rid of NOLOCK!

    UNION ALL

    SELECT tt1.AmountTest1

    ,tt1.AmountTest2

    ,tt1.AmountTest3

    ,tt1.AmountTest4

    FROM Test.dbo.PrePay tt1

    ) AS t

    ) AS t2 ON t1.Id = left(t2.Id_1, 15) + right(t2.Id_1, 2)

    BTW, get rid of NOLOCK: it's not a "go faster" option.

  • Thanks for the insight. However, I'm getting the following error message below:

    Msg 156, Level 15, State 1, Line 22

    Incorrect syntax near the keyword 'From'.

    Msg 156, Level 15, State 1, Line 67

    Incorrect syntax near the keyword 'As'.

    AS t2 ON t1.Id = left(t2.Id_1, 15) + right(t2.Id_1, 2)

  • It's working for me, it must be something else.

    BTW, the script has only 35 lines and it's complaining about an error at line 67, so maybe you're not showing us the whole picture.

  • I don't understand how this code can work.

    Your subqueries to tt1 / t2 don't contain any column named "Id_1" yet you reference that column when you join to t2: I don't understand how SQL resolves that reference.
