Lets suppose there is a stored procedure that has 3 params. END for each Variable if Exists, but that makes the code alot longer than desired.. This method below won't work because its way too long there are about 10 different fields like this, but the example is only 3.

Whenever null was passed, the query should return all the records - essentially ignoring the filter, and whenever a value is passed, it should send only those records filtered by the parameter.
The above sp is a simplified one, and the actual query is pretty complex. I don't want to have a big if statement and two separate select statements, one when the parameter is null and another when it is not null. Connect and share knowledge within a single location that is structured and easy to search. I'm writing a stored procedure about searching the database based on aspx page textbox input text. So I want to skip or ignore where clauses when that parameter values are empty.
But I am confused as to how to handle this situation. The with recompile hint at the end of your statement is telling SQL Server to check the optimization plan "after" replacing the variables by their values.
Doing so it allows to completely ignore a condition when its parameter is null, resulting normally in an optimal execution only on very complex statements you will need to do more in order to help the SQL engine to find the better execution plan. It's also worth noting that using the with recompile clause forces to check for a new plan at every execution instead of reusing an existing one , so if your sentence is going to be executed several times for second, then you will be better suited using an alternative, like parameterized dynamic SQL.
Although this is not the most usual situation. PS: If your parameter can also be an empty string, then use isnull to check both options. You still need to add the recompilation hint to execute it optimally. Stack Overflow for Teams — Collaborate and share knowledge with a private group.
