Dynamic SQL is the only way you can do that.

I strongly recommend you do not go this route. Procedures should have a well-defined function, not do whatever based on a parameter passed. You wouldn't write a function in C# that could return Employees, Departments or Cars depending on the parameters passed, don't do it in SQL.

I gree with Gail on the dynamic SQL part of this. Depending on what you're actually doing, I may agree with her on not doing. It really does depend on the situation.

With that thought is mind, what is the end goal here and why do you think you need to use a variable table name? Are you, for example, using a "poor mans" type of partitioning that uses dates as part of a table name of identically structured tables to indicate what date range the data for each table is in?

ok...thanks

Wait a minute... if you take the time to explain the end goal, there might be a better way. We just don't know the end goal here well enough to come up with an alternate solution and there could be many depending on what you're actually trying to do.
