The term optional parameters refers to a specific variation of the parameter sensitive plan (psp) problem, in which the parameter value at execution time determines whether the query requires a seek or a scan.
Optional Parameters In Sql Server Stored Procedure Databasefaqs Here you will learn about stored procedure parameters, optional parameters, and executing stored procedures with parameters in sql server. Learn about optional parameter plan optimization (oppo) and parameter sensitive plan optimization (pspo) in sql server. This sql server tutorial will explain how to create and use the optional parameters in sql server stored procedure with example step by step. Let’s discuss what we’ve got today first. oppo is for those kitchen sink stored procedures where one query has a lot of optional parameters that might or might not be called at runtime, like this example using the stack overflow database:.

In the code above, i want @genus to be equal to gorilla if not provided, but sql server treats it as null. well, i can set the default value to be the one i used in the table like so: @genus varchar(32) = 'gorilla', but then i have to keep an eye on my default values and make sure they are the same everywhere, which is a bit of a hassle. How to use optional parameters in t sql user defined functions if as a t sql developer or a sql server database administrator in your company you work a lot with sql user defined functions, you might probably require optional parameters in udf's.
