Executing dynamic SQL using sp_executesql sp_executesql is an extended stored procedure that can be used to execute dynamic SQL statements in SQL Server. we need to pass the SQL statement and definition of the parameters used in the SQL statement and finally set the values to the parameters used in the query.
You have to build your query dynamically, at the beginning of the method check whether id is null or equal 0 . To make it easier you can use trick in where clause with 1=1 so where clause can be included all the time in the query.
