-- Purge legacy single-remote storage columns from installs where they are still present.
|
||
|
|
--
|
||
|
|
-- Background: 02.52.25.sql originally used `DROP COLUMN IF EXISTS`, which is a
|
||
|
|
-- MariaDB-only extension and errors on Oracle MySQL 8.x. On MySQL 8 installs the
|
||
|
|
-- migration failed but Joomla still recorded the schema as applied, leaving all 26
|
||
|
|
-- legacy remote_storage/ftp_*/sftp_*/gdrive_*/s3_* columns stranded on the profiles
|
||
|
|
-- table. This migration removes them portably.
|
||
|
|
--
|
||
|
|
-- It must be safe on BOTH engines AND on installs where the columns are already gone
|
||
|
|
-- (MariaDB, or anyone who ran the corrected 02.52.25). Plain `DROP COLUMN` errors when
|
||
|
|
-- a column is absent, and `DROP COLUMN IF EXISTS` errors on MySQL 8 — so neither works
|
||
|
|
-- unconditionally. We gate the drop on INFORMATION_SCHEMA and build the ALTER via a
|
||
|
|
-- prepared statement, which runs on MySQL 8 and MariaDB alike. All 26 columns were
|
||
|
|
-- created and dropped together, so the presence of `remote_storage` gates the whole set.
|
||
|
|
-- When the columns are absent this is a no-op (`DO 0`).
