The optionality of "AS" when aliasing column names is not strange.
Oops. I see that I did not mean "column names". This is about table aliases.
You are missing the point :-) I am not arguing for syntax changes or
anything else in the core of SQLite or SQL.
No, I don't don't think I am missing the point. I'll explain. The
surprise interpretation of "select * from a natral join b; " was made
possible by the combination of 2 features of sqlite:
1. Not requiring AS for table aliases.
2. Treating JOIN without ON constraint as "CROSS JOIN"
1) appears to agree with SQL-92:
http://savage.net.au/SQL/sql-92.bnf.html#correlation%20specification
2) does not:
http://savage.net.au/SQL/sql-92.bnf.html#joined%20table
My point is that the proposed lint mode should worry more about 2) than
1). Setting off alarms for a "missing" AS would just create a lot of
noise since portable SQL might need to omit the AS, as Oracle at least
doesn't allow it.
