The java.sql package provides the CallableStatement interface that can be used to execute stored procedures in a database. The setNull method of this interface is used to set a null parameter value for the stored procedure.
Example 1: In this example, we set a null value for a parameter of type VARCHAR in the stored procedure.
In both these examples, we used the setNull method of the CallableStatement interface to set a null value for the second parameter of the stored procedure. The first parameter is set to a non-null value. These examples use the java.sql package library.
