If you have invoked a database, you have the necessary privileges
    to use the END_STREAM statement.

    If you are using declared streams, you can have more or fewer
    END_STREAM statements than declared START_STREAM statements in
    your program, as long as the structure of the program ensures
    that exactly one END_STREAM statement is executed for each START_
    STREAM statement that is executed.

    If you are using declared streams, you can issue several END_
    STREAM statements in a module. As long as you use the same
    declared stream name in each END_STREAM statement, the END_STREAM
    statements will all refer to the same stream.
