Hi,

I am using the below query to sum two columns values and I couldn't sum it.
I get this error:Operand data type varchar is invalid for subtract operator

Query:

Variance = '$ ' + REVERSE(SUBSTRING(REVERSE(CONVERT(VARCHAR,cast(round(isnull(sum(Current_Tear),0),0)as money),1)),4,255)) -
'$ ' + REVERSE(SUBSTRING(REVERSE(CONVERT(VARCHAR,cast(round(isnull(sum(Previous_Year),0),0)as money),1)),4,255))

The error message says it all:Operand data type varchar is invalid for subtract operator


Variance = '$ ' + REVERSE(SUBSTRING(REVERSE(CONVERT(VARCHAR,cast(round(isnull(sum(Current_Tear),0),0)as money),1)),4,255)) - <<<<<< This is your subtract operator
'$ ' + REVERSE(SUBSTRING(REVERSE(CONVERT(VARCHAR,cast(round(isnull(sum(Previous_Year),0),0)as money),1)),4,255))



If you want to concatenate the "-" sign use this:


Variance = '$ ' + REVERSE(SUBSTRING(REVERSE(CONVERT(VARCHAR,cast(round(isnull(sum(Current_Tear),0),0)as money),1)),4,255)) + '-' +
'$ ' + REVERSE(SUBSTRING(REVERSE(CONVERT(VARCHAR,cast(round(isnull(sum(Previous_Year),0),0)as money),1)),4,255))



Otherwise, I have no idea what you're trying to do.

does the following get anywhere close



SELECT '$ ' + CAST(CAST(Round(SUM(Current_Year),0) as INT) -
CAST(Round(SUM(Previous_Year),0) as INT) as varchar)
