This patch adds support for associative arrays in stored procedures
for sql_mode=ORACLE.
The syntax follows Oracle's PL/SQL syntax for associative arrays -
TYPE assoc_array_t IS TABLE OF VARCHAR2(100) INDEX BY INTEGER;
or
TYPE assoc_array_t IS TABLE OF record_t INDEX BY VARCHAR2(100);
where record_t is a record type.
The following functions were added for associative arrays:
- COUNT - Retrieve the number of elements within the arra
- EXISTS - Check whether given key exists in the array
- FIRST - Retrieve the first key in the array
- LAST - Retrieve the last key in the array
- PRIOR - Retrieve the key before the given key
- NEXT - Retrieve the key after the given key
- DELETE - Remove the element with the given key or remove all elements
if no key is given
The arrays/elements can be initialized with the following methods:
- Constructor
i.e. array:= assoc_array_t('key1'=>1, 'key2'=>2, 'key3'=>3)
- Assignment
i.e. array(key):= record_t(1, 2)
- SELECT INTO
i.e. SELECT x INTO array(key)
TODOs:
- Nested tables are not supported yet.
i.e. TYPE assoc_array_t IS TABLE OF other_assoc_array_t INDEX BY INTEGER;
- Associative arrays comparisons are not supported yet.

MariaDB: The innovative open source database
MariaDB was designed as a drop-in replacement of MySQL(R) with more features, new storage engines, fewer bugs, and better performance.
MariaDB is brought to you by the MariaDB Foundation and the MariaDB Corporation. Please read the CREDITS file for details about the MariaDB Foundation, and who is developing MariaDB.
MariaDB is developed by many of the original developers of MySQL who now work for the MariaDB Corporation, the MariaDB Foundation and by many people in the community.
MySQL, which is the base of MariaDB, is a product and trademark of Oracle Corporation, Inc. For a list of developers and other contributors, see the Credits appendix. You can also run 'SHOW authors' to get a list of active contributors.
A description of the MariaDB project and a manual can be found at:

Getting the code, building it and testing it
Refer to the following guide: https://mariadb.org/get-involved/getting-started-for-developers/get-code-build-test/ which outlines how to build the source code correctly and run the MariaDB testing framework, as well as which branch to target for your contributions.
Help
