To be exact, it is send to the SQL server as a prepared statement. Whether the SQL server executes it as a prepared statement (uses a cached plan and inserts the parameters in there) is up to the SQL implementation. > - If you don't use cfqueryparams, the query is not executed as a prepared > statement. It is not send to the SQL server as a prepared statement. If the SQL implementation has a caching mechanism that can cache execution plans for inline statements it could still use a cached plan. > 1) can you have queries with cfqueryparams not be executed as prepared > statements on the SQL server? With some implementations. > 2) could prepared statements have an adverse effect on performance? Yes.
