All,
I've recently started using MS SQL Server / SSRS.
For a new report I've created, I'm trying to create a filter for several columns that allows the user to choose to either show all rows, or only rows that have a NULL value in the relevent field.
'So far, I've only managed to created a filter that shows either the NULL, or the non-NULL values, but this isn't workable for the users.
Current filter related to a Boolean parameter that returns TRUE or FALSE
Current filter set-up:
Expression: =IsNothing(Fields!name.Value)
Operator: =
Value: =Parameters!name_empty.Value
How do I implement the required functionality?
