[rql2sql] fix relation table scope when some variable from subquery is used. Closes #3252270
While it feels weird to drop this explicit ColumnAlias handling, hg history has
no clue on its introduction (prior to rev 0) and no older test case fails
without it, so let's drop it.
/* -*- 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;
END ;;
