Select Acct,Period,F_year, Sum(AMT) as Amtfrom dbo.CosGroup By Acct,Period,F_yearWhere Amt is not nullBut i am acquiring this error:

Msg 8117, Level 16, State 1, Line 1Operand also data kind varchar is invalid for amount operator.Can anyone aid me?

Try doing this:

Select Acct,Period,F_year, Sum(isnull(cast(AMT as float),0)) as Amtfrom dbo.CosGroup By Acct,Period,F_year

Apparently, the value "1669.57" is a string. So what does it mean to add this value to another?

The error message is correct: It"s not valid to include text worths together. If it was valid, I could not tell what the result need to be.

You are watching: Operand data type varchar is invalid for sum operator

You should either readjust your column type to a numeric type, or convert it somejust how prior to trying to include it.

If Amt is intfinished to be provided for mathematical operations, then it must be kind Decimal and also not varchar.
