Hi
I am noticing from my slow log file (5 secs) that the following query
on mysql 4.0.24 is taking a 11 secs
# Query_time: 11 Lock_time: 0 Rows_sent: 299925 Rows_examined: 983836
use rt3;
SELECT * FROM Transactions where Transactions.type = 'create';
Now looking at the explain I see
mysql> explain SELECT * FROM Transactions where Transactions.type = 'create';
+--------------+------+---------------+------+---------+------+--------+-------------+
| table | type | possible_keys | key | key_len | ref | rows
| Extra |
+--------------+------+---------------+------+---------+------+--------+-------------+
| Transactions | ALL | NULL | NULL | NULL | NULL | 984572
| Using where |
+--------------+------+---------------+------+---------+------+--------+-------------+
It has to go thru about 1 million rows and not using any index.
Is there any index, that I can create, to improve this w/o hurting any
other query?
