sql/sql_table.cc:

sql/sql_select.cc:
back to the bug #1274:
the following query
EXPLAIN SELECT SQL_CALC_FOUND_ROWS race_name
FROM races WHERE race_name LIKE '%Madison%' ORDER BY race_date DESC LIMIT 0,100
+-------+------+---------------+------+---------+------+--------+-----------------------------+
| table | type | possible_keys | key | key_len | ref | rows | Extra |
+-------+------+---------------+------+---------+------+--------+-----------------------------+
| races | ALL | NULL | NULL | NULL | NULL | 505821 | Using where; Using filesort |
+-------+------+---------------+------+---------+------+--------+-----------------------------+
The query returns no rows.
There are two problems with it:
- wrong access plan is chosed (sequential index scan in reverse order,
which is VERY SLOW in case of MyISAM table + packed keys)
It's wrong, because it doesn't take into account that SQL_CALC_FOUND_ROWS
is present, in other words, is based on assumtion that LIMIT
clause decrease number of rows to access significantly, which is
not true as all rows are accessed.
- the access plan is not shown in the EXPLAIN (bug #1560). I'm not
fixing it here
new EXPLAIN parameter to show real query as it was interpreted
