Ouch, I'm glad you folks take care of reading such stuff! What you put in the documentation was much much clearer--just wish I had found it! Speaking of which, I had looked at the "From" section of the "SELECT" page ( https://www.postgresql.org/docs/current/static/sql-select.html#SQL-FROM), which also has a somewhat detailed section on joins. I'm wondering about the utility of: - Adding a link from the "SELECT" page (FROM section) to the page Tom referenced (which includes a link the other way) and/or - Adding this detail to the section on USING on the select page: A clause of the form USING ( a, b, ... ) is shorthand for ON left_table.a = right_table.a AND left_table.b = right_table.b .... Also, USING implies that only one of each pair of equivalent columns will be included in the join output, not both. *Outcome columns specified by USING will appear first in the joined results.* Cheers, Ken > >
