Invoking a procedure using the CALL command

If a procedure uses only IN parameters, Derby can execute the procedure by using the SQL CALL command. A stored procedure with IN, OUT, or INOUT parameters can be invoked from a client application by using the CallableStatement method. You can invoke the procedure in an SQL statement such as the following:

Note: You cannot roll back this statement, because commits occur within the procedure itself. Procedures that use nested connections, on the other hand, are not permitted to commit or roll back and can therefore be rolled back after the calling statement.

You can also use the CALL command to execute a procedure that does return a value, but you will not be able to access the value.
