SQL::Query::Join Object

Description

Internal use only. The SQL::Query::Join object fully describes the joining of a parent table to a referenced table. Key properties include .JoinType and (if an outer join) the .OuterJoinType.

Name
Description
SQL::Query::Join::Parse Function

Parse the SQLStatement passed (or the value previously set into the SQLStatement property).

SQL::Query::Join::Reset Function

Reset the query as if it had just been created.

Joins can nest. A SelectTableReference can contain a join and that join has a table reference which can also contain a join and so on.
