Hi Everyone,
I am receiving the error message 'Incorrect syntax near the keyword 'ELSE'.' from the query section below -
CASE WHEN T3.LineTotal IS NULL THEN ((T0.Rate * SUM(T0.LineTotal)) - ((T0.DiscPrcnt / 100)) ELSE (((T0.Rate * SUM(T0.LineTotal)) - (T0.DiscPrcnt / 100)) + T3.LineTotal) END AS 'Total NATIVE'
If anybody can suggest how to fix this error it will be greatly appreciated.
Kind Regards,
David

Try this:

CASE WHEN T3.LineTotal IS NULL THEN T0.Rate * SUM(T0.LineTotal) - (T0.DiscPrcnt / 100) ELSE ((T0.Rate * SUM(T0.LineTotal)) - (T0.DiscPrcnt / 100)) + T3.LineTotal) END AS 'Total NATIVE'

It looks like parens where mismatched. Of course I could be way off base here. Without seeing the whole query it is a guess at best.

Quick note, as LinksUp noted, the parentheses do not match, there is an extra opening one before the first instance of T0.DiscPrcnt. To prevent/detect this kind of errors, I find it easier to fold the CASE statement.

CASE

WHEN T3.LineTotal IS NULL THEN ((T0.Rate * SUM(T0.LineTotal)) - (T0.DiscPrcnt / 100))

ELSE (((T0.Rate * SUM(T0.LineTotal)) - (T0.DiscPrcnt / 100)) + T3.LineTotal)

END AS 'Total NATIVE'

I find it easier to use ISNULL:

SELECT (T0.Rate * SUM(T0.LineTotal) - (T0.DiscPrcnt / 100) + ISNULL(T3.LineTotal,0) AS 'Total NATIVE'

Thanks for everyone's generous responses - the extra parenthesis was definitely the issue!
