mariadb-create-function

MariaDB-specific syntax and behavior for CREATE FUNCTION across its three distinct forms — stored functions (RETURNS + RETURN, IN/OUT/INOUT parameters, DETERMINISTIC/binlog interaction), stored aggregate functions (CREATE AGGREGATE FUNCTION with FETCH GROUP NEXT ROW), and loadable user-defined functions (CREATE FUNCTION ... SONAME 'lib.so', a plugin_dir-loaded shared library unrelated to stored routines). Use when writing, generating, or reviewing any CREATE FUNCTION statement, a custom aggregate, or a UDF registration targeting MariaDB.
