Cognos doesn't have "variables" in the same sense that they exist in programming.  Cognos has "Parameters" (which are text-based placeholders for prompted values), and "Conditional Variables", which are expressions evaluated at runtime to modify the presentation of the report.

You're probably looking to use a "parameter" here.  As I mentioned above, a parameter is text based, and is cast to the appropriate data type when it is put into the SQL.  That creates a bit of a prolbme if you're trying to display the parameter , becuase you can't format it.  

The solution to this is to create a data item in a query, and cast it to the appropriate database type.  The downside is that it has to get sent to the database.
