Jon Leighton	1de1041c00	Add Nodes::TableAlias#engine ... Eventually #engine should go away, but until that time, this means that Table and Nodes::TableAlias can be used more interchangeably.	2012-07-13 11:19:17 +01:00

Jon Leighton	a855308204	Add an #table_name method to Table and TableAlias, which always returns the actual table name, not the alias. Then fix ToSql#column_for to use this table name when checking whether the table exists (rather than before, where it was checking whether a table with the alias name exists, which was incorrect).	2011-03-04 06:17:18 +08:00
