问题
I need to use the SSRS Switch function to fill background colour
=switch(Fields!Ref_No.Value="AAA","Green",Fields!Ref_No.Value= not like "AAA","RED"
How do I say if first 3 letters not like AAA then fill background Red?
回答1:
Just use Left and <>:
=Switch(Fields!Ref_No.Value="AAA", "Green"
, Left(Fields!Ref_No.Value, 3) <> "AAA", "Red")
Left makes sure you're considering the first three characters only as per your requirement.
