CREATE_PROGRAM v18

Use the CREATE_PROGRAM procedure to create a DBMS_SCHEDULER program. The signature is:

CREATE_PROGRAM(
  <program_name> IN VARCHAR2,
  <program_type> IN VARCHAR2,
  <program_action> IN VARCHAR2,
  <number_of_arguments> IN PLS_INTEGER DEFAULT 0,
  <enabled> IN BOOLEAN DEFAULT FALSE,
  <comments> IN VARCHAR2 DEFAULT NULL)

Parameters

program_name

program_name specifies the name of the program that's being created.

program_type

program_type specifies the type of program. The current implementation of CREATE_PROGRAM supports a program_type of PLSQL_BLOCK or PROCEDURE.

program_action

• If program_type is PLSQL_BLOCK, program_action contains the PL/SQL block that executes when the program is invoked. The PL/SQL block must be terminated with a semi-colon (;).

• If program_type is PROCEDURE, program_action contains the name of the stored procedure.

number_of_arguments

• If program_type is PLSQL_BLOCK, this argument is ignored.

• If program_type is PROCEDURE, number_of_arguments specifies the number of arguments required by the procedure. The default value is 0.

enabled

enabled specifies if the program is created enabled or disabled:

• If enabled is TRUE, the program is created enabled.

• If enabled is FALSE, the program is created disabled. Use the DBMS_SCHEDULER.ENABLE program to enable a disabled program.

  The default value is FALSE.

comments

Use the comments parameter to specify a comment about the program. By default, this parameter is NULL.

Example

The following call to the CREATE_PROGRAM procedure creates a program named update_log:

EXEC
  DBMS_SCHEDULER.CREATE_PROGRAM (
    program_name     => 'update_log',
    program_type     => 'PLSQL_BLOCK',
    program_action   => 'BEGIN INSERT INTO my_log VALUES(current_timestamp);
                         END;',
    enabled          => TRUE,
    comments         => 'This program adds a row to the my_log table.');

update_log is a PL/SQL block that adds a row containing the current date and time to the my_log table. The program is enabled when the CREATE_PROGRAM procedure executes.
