Join them; it only takes a minute: Sign up I need a MySQL query to be optimized up vote 0 down vote favorite I have a query running on MySQL DB and is very slow. Is there anyway I can optimize the following SELECT mcm.merchant_name, ( ( Sum(ot.price) + Sum(ot.handling_charges) + Sum(ot.sales_tax_recd) + Sum(ot.shipping_cost) - Sum(ot.sales_tax_payable) ) - mysql error code Sum(im.break_even_cost) ) AS PL, ot.merchant_id FROM order_table ot, item_master im, merchant_master mcm WHERE ot.item_id = im.item_id AND ot.merchant_id = mcm.merchant_id GROUP BY mcm.merchant_name ORDER BY pl DESC LIMIT 0, 10; The Above Query is taking more than 200 seconds to execute. Explain Result: id select_type table type possible_keys key key_len ref rows Extra 1 SIMPLE ot ALL "merchant_id,item_id" NULL NULL NULL 507910 "Using temporary; Using filesort" 1 SIMPLE mcm eq_ref "PRIMARY,merchant_id" PRIMARY 4 stores.ot.merchant_id 1 1 SIMPLE im eq_ref "PRIMARY,item_id" PRIMARY 4 stores.ot.item_id 1 Also, I got Error-1003 when I run EXPLAIN EXTENDED mysql select query-optimization share|improve this question edited Dec 6 '13 at 6:56 asked Dec 6 '13 at 6:24 user2992030 255 You should post output of this query with "EXPLAIN EXTENDED" prefix (EXPLAIN EXTENDED SELECT mcm.merchant_name,...) –Māris Kiseļovs Dec 6 '13 at 6:27 This will tend to be more of an schema design question, the query it self isn't anything too over the top. –Matt R.

isn't so readable and understandable as it has to be. Some of us even tried to create or use external pretty-printing programs and other complicated converters to make EXPLAIN's output less cryptic, for example nice Percona's Visual Explain script. But from now we have a native MySQL command that explains query execution plan in a better human-readable and machine-readable way: EXPLAIN FORMAT=JSON! A trivial example, SELECT from a single table:mysql> CREATE TABLE t1 (i INT, j INT); Query OK, 0 rows affected (0.00 sec) mysql> EXPLAIN SELECT * FROM t1; +----+-------------+-------+--------+---------------+------+---------+------+------+---------------------+ | id | select_type | table | type | possible_keys | key | key_len | ref | rows | Extra | +----+-------------+-------+--------+---------------+------+---------+------+------+---------------------+ | 1 | SIMPLE | t1 | system | NULL | NULL | NULL | NULL | 0 | const row not found | +----+-------------+-------+--------+---------------+------+---------+------+------+---------------------+ 1 row in set (0.00 sec) mysql> EXPLAIN FORMAT=JSON SELECT * FROM t1; +------------------------------------------------- ... | EXPLAIN +------------------------------------------------- ... | { "query_block": { "select_id": 1, "table": { "table_name": "t1", "access_type": "system", "rows": 0, "filtered": 0, "const_row_not_found": true } } } | +------------------------------------------------- ... 1 row in set, 1 warning (0.00 sec) mysql> SHOW WARNINGS; +-------+------+----------------------------------------------------------------+ | Level | Code | Message | +-------+------+----------------------------------------------------------------+ | Note | 1003 | /* select#1 */ select NULL AS `i`,NULL AS `j` from `test`.`t1` | +-------+------+----------------------------------------------------------------+ 1 row in set (0.00 sec) Moreover, new EXPLAIN is not just a 1-to-1 translator of the old EXPLAIN command output. JSON output is much more informative: it tries to display a real execution path of the query; it describes pushed conditions; temporary table and index creation is displayed in more precise More advanced example, nested loop join and pushed conditions (see "attached_conditions"):mysql> CREATE TABLE t2 (i INT KEY, j INT); Query OK, 0 rows affected (0.00 sec) mysql> INSERT INTO t1 VALUES (1, 1), (2, 2), (3, 3); Query OK, 3 rows affected (0.00 sec) Records: 3 Duplicates: 0 Warnings: 0 mysql> INSERT INTO t2 SELECT * FROM t1; Query OK, 3 ro
