Creating Procedures with IN and OUT Parameters

This section describes how to create a procedure with IN and OUT parameters.

To do more tests on CallableStatement objects, I created another stored procedure with IN and OUT parameters:

C:\>sqlplus
Enter user-name: Herong/TopSecret

SQL> -- Creating a stored procedure
SQL> CREATE PROCEDURE CountChar(String IN CHAR, 
  2    Count OUT INTEGER) AS
  3  BEGIN
  4    Count := LENGTH(String);
  5  END;
  6  /

Procedure created.

SQL> -- Turning on server output for PUT_LINE()
SQL> SET SERVEROUTPUT ON;

SQL> -- Testing the procedure with an anonymous procedure
SQL> DECLARE
  2    C INTEGER;
  3  BEGIN
  4    CountChar('Herong',C);
  5    DBMS_OUTPUT.PUT_LINE('Count: ' || C);
  6  END;
  7  /
Count: 6

PL/SQL procedure successfully completed.

Note that I had to use an anonymous procedure to test CountChar(), because the output variable needs to be declared.
