Without knowing your sql select statement it is hard to know.

FROM http://msdn2.microsoft.com/en-us/library/ms188001.aspx

Being able to substitute parameters in sp_executesql offers the following advantages to using the EXECUTE statement to execute a string:

    * Because the actual text of the Transact-SQL statement in the sp_executesql string does not change between executions, the query optimizer will probably match the Transact-SQL statement in the second execution with the execution plan generated for the first execution. Therefore, SQL Server does not have to compile the second statement.
    * The Transact-SQL string is built only one time.
    * The integer parameter is specified in its native format. Casting to Unicode is not required.
