Hi
I am battling to pass an expression in a variable
in SSIS driving me nuts
i have a simple select statement and one of the fields is s numeric (10.0)
I have a variable in SSIS which i want to use as part of the WHERE clause on this numeric field but i keep getting the following error

>>AND TCMSourceSystemID =" + @[User::TCMSourceSystemID]  + "

"Data Types DT_WSTR and DT_R8" are incompatible for binary operator +

thanks


"
SELECT TCMSourceSystemID, SourceCustID  FROM " + @[User::TargetSchema] + ".TCMStdCustomerMapSourceMULTI
WHERE TCMBusinessDate = '" + @[User::TCMBusinessDate]  + "' AND TCMSourceSystemID =" + @[User::TCMSourceSystemID]  + "
"

Not sure what's the 100% correct syntax, but i think you should convert your number to a varchar type or something like that ...

... + cast(@[User::TCMSourceSystemID] as nvarchar(50)) ...

You are using string concatenation to create your sql-statement, so everything has to be text to be concatenated with the rest of the statement. You can and should convert!
