I have the following query in C# that pulls based on entries in a listbox, I can't use a stored procedure against this datasource.

Select * From events Where charindex(',' + events.AcctNumber + ',', ',' + @AcctNumber + ',')>0 and (eventdate Between @StartDate and @EndDate)

How can I write this so if the @Acctnumber is blank, it would select "ALL" records between the @StartDate and @EndDate

Just put an OR into it.

C#

Select * From events Where (charindex(',' + events.AcctNumber + ',', ',' + @AcctNumber + ',')>0 OR @AcctNumber = '') and (eventdate Between @StartDate and @EndDate)
