[hooks] build EnsureSymmetricRelations{Add,Delete} dynamically
Instead of setting the __select__ attribute at registration time, which
confuses the filterable_selectors cache when running different tests (with
different schemas) in the same process, just make entirely new classes.
Closes #8785708.
/* -*- sql -*-
mysql specific registered procedures,
*/
/* XXX limit_size version dealing with format as postgres version does.
XXX mysql doesn't support overloading, each function should have a different name
NOTE: fulltext renamed since it cause a mysql name conflict
*/
CREATE FUNCTION text_limit_size(vfulltext TEXT, maxsize INT)
RETURNS TEXT
NO SQL
BEGIN
IF LENGTH(vfulltext) < maxsize THEN
RETURN vfulltext;
ELSE
RETURN SUBSTRING(vfulltext from 1 for maxsize) || '...';
END IF;
