  • Update Regarding Multitracks + Registration

    It's clear that this thread needs some love and attention. A lot of the links have either expired or been miss-labelled. With the amount of tracks there are, this is quite a practice. I have made the decision to lock this thread from further replies and to put out this notice that I will be refreshing this thread with updated links and guidance where needed.

    I will update the thread on multitracks and the first post with any forth coming updates about this in due course. For information - I have also disabled user registrations to do some tidyup. Stay tuned.

An SQL join clause – corresponding to a join operation in relational algebra – combines columns from one or more tables in a relational database. It creates a set that can be saved as a table or used as it is. A JOIN is a means for combining columns from one (self-join) or more tables by using values common to each. ANSI-standard SQL specifies five types of JOIN: INNER, LEFT OUTER, RIGHT OUTER, FULL OUTER and CROSS. As a special case, a table (base table, view, or joined table) can JOIN to itself in a self-Join.
A programmer declares a JOIN statement to identify rows for joining. If the evaluated predicate is true, the combined row is then produced in the expected format, a row set or a temporary table.
