Description:
LIMIT clause is a syntax error when using multi-table DELETE

How to repeat:
mysql> delete from a left join b on a.i=b.i limit 1;
ERROR 1064: You have an error in your SQL syntax.  Check the manual that corresp
onds to your MySQL server version for the right syntax to use near 'left join b
on a.i=b.i limit 1' at line 1

Suggested fix:
Fix the parser. :)

Oopsie, wrong query:

mysql> delete a from a left join b on a.i=b.i limit 1;
ERROR 1064: You have an error in your SQL syntax.  Check the manual that corresp
onds to your MySQL server version for the right syntax to use near 'limit 1' at
line 1

ORDER BY .. LIMIT ... will not be introduced in either multi-table updates nor deletes for many reasons, of which the most important one is the ambiguity of number of tuples and great probability of breaking entity integrity with non-transactional tables.
