073d9e5f09 A bug fix and test case for a bug that appears in quereis where there 
is a GROUP BY a column that is not NOT NULL and ORDER BY is done by
another column.

Even better fix would be to make a separate function for this.

Sinisa@sinisa.nasamreza.org
b42ec166c0 Surgical changes in sql_select and sql_union code in order to 
accomodate EXPLAIN properly for all possible variant of UNION's
derived tables etc ...

This also fixes all reported (and unreported) bugs when EXPLAIN is
run on UNION's.

select_describe() now has a very dirty hack to avoid some problems
with transactional tables on table unlocking.

Code speedup is possible. For the moment all that was important was
that all tests are passed.

Sinisa@sinisa.nasamreza.org
4ed4546004 Changes for the BitKeeper resolve. 
One more notice:

limiting number of queries per hour for different users has been done
on 4.0.1 , but I can port it to 3.23.* 

This will require only certain changes, like number of columns in user
table.

I will also make a test case for it, after it is approved by Monty, 
as result file will depend on the error message text.
 2001-12-26 17:42:06 +02:00
Sinisa@sinisa.nasamreza.org
038db406c1 This is a large push. Included are : 
* multi-table updates
* new paid feature for limiting number of queries per hour for users
* optional syntax for multi-table deletes
* optimization for SQL_CALC_FOUND_ROWS
* a small addition for CREATE .. SELECT that will be of future use

I know that all this will require many additions to documentation, 
which I have not done, but I am at Arjen's disposal to help him document
all this.
