I create the following package in Oracle-19.0 and call its procedure:

CREATE OR REPLACE PACKAGE pkg AS

  PROCEDURE p1;

END;

CREATE OR REPLACE PACKAGE BODY pkg AS

  a INT:=11;

  b INT:=10;

  FUNCTION f1 RETURN INT AS

  BEGIN

    a:=a-1;

    RETURN a;

  END;

  PROCEDURE p1 AS

    res VARCHAR(1024):= a || ' ' || f1() || ' ' || a;

  BEGIN

    DBMS_OUTPUT.PUT_LINE(res);

  END;

BEGIN

  a:=a-b;

END;

CALL pkg.p1();

Statement processed.

0 0 0

Now I create the same package in MariaDB (in Oracle compatibility mode) and call its procedure:

SET sql_mode=ORACLE;

DELIMITER /

CREATE OR REPLACE PACKAGE pkg AS

  PROCEDURE p1;

END;

CREATE OR REPLACE PACKAGE BODY pkg AS

  a INT:=11;

  b INT:=10;

  FUNCTION f1 RETURN INT AS

  BEGIN

    a:=a-1;

    RETURN a;

  END;

  PROCEDURE p1 AS

    res VARCHAR(1024):= a || ' ' || f1() || ' ' || a;

  BEGIN

    SELECT res;

  END;

BEGIN

  a:=a-b;

END;

DELIMITER ;

CALL pkg.p1();

+-------+

| res   |

+-------+

| 1 0 1 |

Notice, it returns a different result.

is caused by
