Would it be necessary to queryparam the active bit, since it isn't really dynamic? I belive he is right as well. However, from what I can remember, it was not necessary to have all the "static" values query-paramed. So, in the above, the FORM. Then, the active bit could stay as is. The point of the blog post was to show the difference between a SQL statement that had no query params and a SQL statement that had at least one.

The one that had at least one SQL statement performed better. The SQL server is caching the query as a stored procedure. Items that are in queryparams are dynamically passed in and evaluated on every query. Comment 15 by James, F. This helps. How do they get round it yet CF doesn't support them together?

Maybe wait and see what CF8 offers. The reason for this is so that the next time that query is executed, SQL Server will be able to reuse the previously generated Execution Plan, and not have to go through the overhead of generating it again. So, for example, if we were to run the following query and then check the Plan Cache, we would see where SQL Server has generated an Execution Plan for it.

Notice how the variable that we passed to the query is actually a hard coded value when SQL Server runs the query. Now, if we were to change the value of the variable we are using in our query, then check the Plan Cache, we would see that SQL Server has generated a separate Execution Plan for this query, which would have the new variable value hard coded.

In fact, if we were to loop through multiple values for our variable, SQL Server would generate an Execution Plan for each version of our query: Why is this a problem? When the variable in our query is rendered by ColdFusion and the query is processed, SQL Server sees each version of the query as a completely different query and therefore has to create a new Execution Plan for it.
