How to commit individual transaction in Oracle PLSQL - oracle

Question

I need to write a PL/SQL procedure, within this procedure I need to call another procedure within its own transaction bounds, and commit it regardless of failure or commit of main transaction. In other words I need something like REQUIRES NEW transaction propagation.
Something like:
procedure mainProcedure(arugements) is
begin
// some statements
nestedProcedure(someArguments);
// some other statements
end;
procedure nestedProcedure(arguments) is
begin
// start a new transaction
// some statements, lock some objects!
// commit the new transaction and release locked objects
end;
How can I achieve this?

Answer 1

Have a look at Autonomous transation. Also see demo
CREATE TABLE t (
test_value VARCHAR2(25));
CREATE OR REPLACE PROCEDURE child_block IS
PRAGMA AUTONOMOUS_TRANSACTION;
BEGIN
INSERT INTO t
(test_value)
VALUES
('Child block insert');
COMMIT;
END child_block;
/
CREATE OR REPLACE PROCEDURE parent_block IS
BEGIN
INSERT INTO t
(test_value)
VALUES
('Parent block insert');
child_block;
ROLLBACK;
END parent_block;
/
Execution:
-- empty the test table
TRUNCATE TABLE t;
-- run the parent procedure
exec parent_block;
-- check the results
SELECT * FROM t;

You may use pragma autonomous_transaction. It does the same what you need. But don't forget that in the sub transaction you will not see any updates from above transactions.
procedure mainProcedure(arugements) is
begin
// some statements
nestedProcedure(someArguments);
// some other statements
end;
procedure nestedProcedure(arguments) is
pragma autonomous_transaction;
begin
// start a new transaction
// some statements, lock some objects!
// commit the new transaction and release locked objects
commit;
end;

Create a (Commit single transaction Procedure), you can create the procedure and use it as illustrated in the comments.
CREATE OR REPLACE PROCEDURE SWD_AUTON_DML (p_dmlstat VARCHAR2)
AS
PRAGMA AUTONOMOUS_TRANSACTION;
BEGIN -- Main transaction suspends here.
EXECUTE IMMEDIATE p_dmlstat; -- Autonomous transaction begins here.
COMMIT; -- Autonomous transaction ends here.
END; -- Main transaction resumes here.
--------------------- How to USE -------------------------------------
----------------------------------------------------------------------
---EXECUTE AUTON_DML(q'[UPDATE staging_pm_schedule_table SET NOTE = 'TEST_Variable']');
--OR
---EXECUTE AUTON_DML('UPDATE staging_pm_schedule_table SET NOTE = '''TEST_Variable'''');
