MDEV-11952 Oracle-style packages: stage#5
- CREATE PACKAGE [BODY] statements are now entirely written to mysql.proc with type='PACKAGE' and type='PACKAGE BODY'. - CREATE PACKAGE BODY now supports IF NOT EXISTS - DROP PACKAGE BODY now supports IF EXISTS - CREATE OR REPLACE PACKAGE [BODY] is now supported - CREATE PACKAGE [BODY] now support the DEFINER clause: CREATE DEFINER user@host PACKAGE pkg ... END; CREATE DEFINER user@host PACKAGE BODY pkg ... END; - CREATE PACKAGE [BODY] now supports SQL SECURITY and COMMENT clauses, e.g.: CREATE PACKAGE p1 SQL SECURITY INVOKER COMMENT "comment" AS ... END; - Package routines are now created from the package CREATE PACKAGE BODY statement and don't produce individual records in mysql.proc. - CREATE PACKAGE BODY now supports package-wide variables. Package variables can be read and set inside package routines. Package variables are stored in a separate sp_rcontext, which is cached in THD on the first packate routine call. - CREATE PACKAGE BODY now supports the initialization section. - All public routines (i.e. declared in CREATE PACKAGE) must have implementations in CREATE PACKAGE BODY - Only public package routines are available outside of the package - {CREATE|DROP} PACKAGE [BODY] now respects CREATE ROUTINE and ALTER ROUTINE privileges - "GRANT EXECUTE ON PACKAGE BODY pkg" is now supported - SHOW CREATE PACKAGE [BODY] is now supported - SHOW PACKAGE [BODY] STATUS is now supported - CREATE and DROP for PACKAGE [BODY] now works for non-current databases - mysqldump now supports packages - "SHOW {PROCEDURE|FUNCTION) CODE pkg.routine" now works for package routines - "SHOW PACKAGE BODY CODE pkg" now works (the package initialization section) - A new package body level MDL was added - Recursive calls for package procedures are now possible - Routine forward declarations in CREATE PACKATE BODY are now supported. - Package body variables now work as SP OUT parameters - Package body variables now work as SELECT INTO targets - Package body variables now support ROW, %ROWTYPE, %TYPE
