What is SSRS and why do you post a question about it in an Access forum?

Not sure what you mean by Min and Max Dates. If you mean the Minimum and Maximum dates that happen in the data, you can just use a far past and far future date in an IIF or NZ statement and let the data worry about itself.

WHERE TheDate >= NZ(MyStartDate,#01/01/1900#) 
AND  TheDate <= NZ(MyEndDate,#12/31/2199#)

Nz might not work in SSRS (whatever that is). I think it is an Access function. I have known it to fail in Excel VBA code. I tried to have Excel link to Access query that used Nz and it bombed. Had to change the query. If Nz fails try the IIf:


WHERE TheDate BETWEEN IIf(IsNull([MyStartDate]),#01/01/1900#,[MyStartDate]) AND IIf(IsNull([MyEndDate]),#12/31/2199#,[MyEndDate])
