Обсуждение: SQL

Hi,

I'd like an information about the history of SQL. 
The similarities and differences between SQL1 and SQL2 and SQL3.

Thank you,

It's your query.  In a GROUP BY query, all named columns must either
contain and aggregate function (e.g. SUM) or be named in the GROUP BY
clause.

O'Reilly has just come out with a SQL in a Nutshell book.  I'd suggest
picking one up.
