mariadb-create-index

MariaDB-specific syntax and behavior for CREATE INDEX / DROP INDEX — that it maps to ALTER TABLE (batch multiple adds), can't create a PRIMARY KEY, needs a prefix length on TEXT/BLOB columns, has no expression/functional indexes (index a generated column instead), real descending indexes (since 10.8), IGNORED indexes for safe optimizer testing, UNIQUE/FULLTEXT/SPATIAL/VECTOR kinds, USING BTREE/HASH/RTREE, CREATE OR REPLACE / IF NOT EXISTS, KEY_BLOCK_SIZE being ignored here, and dropping a PRIMARY KEY via DROP INDEX PRIMARY. Use when writing, generating, or reviewing CREATE INDEX / DROP INDEX statements that target MariaDB.
