MariaDB starting with 10.3.5
----------------------------
Oracle-style packages were introduced in MariaDB 10.3.5.

Syntax
------

SHOW PACKAGE STATUS
  [LIKE 'pattern' | WHERE expr]

Description
-----------

The SHOW PACKAGE STATUS statement returns characteristics of stored package
specifications, such as the database, name, type, creator, creation and
modification dates, and character set information. A similar statement, SHOW
PACKAGE BODY STATUS, displays information about stored package bodies (i.e.
implementations).

The LIKE clause, if present, indicates which package names to match. The WHERE
and LIKE clauses can be given to select rows using more general conditions, as
discussed in Extended SHOW.

The ROUTINES table in the INFORMATION_SCHEMA database contains more detailed
information.

Examples
--------
