ALTER TABLE /*_*/categorylinks MODIFY cl_to VARBINARY(255) DEFAULT '' NOT NULL;
ALTER TABLE /*_*/categorylinks MODIFY cl_sortkey_prefix VARBINARY(255) DEFAULT '' NOT NULL;
Migrate categorylinks to abstract schema To get MySQL/SQLite migrated, changing type of cl_to and cl_sortkey_prefix from "varchar() binary" to varbinary For Postgres: - Dropping foreign key on cl_from - Setting proper default for cl_from, cl_to, cl_sortkey, cl_collation - Set cl_sortkey to not nullable - Dropping unique index cl_from which in turn should become PK - Adding several missing indexes - Fixing columns of cl_sortkey Bug: T230428 Bug: T164898 Change-Id: I83043ef41f9c753734f1e4b51237d979031dd71a 2020-11-28 11:16:20 +00:00			`ALTER TABLE /_/categorylinks MODIFY cl_to VARBINARY(255) DEFAULT '' NOT NULL;`
