command line interface - MySQL Query with LARGE number of records gets Killed -


i run following query shell :

    mysql -h my-host.net -u myuser -p -e "select component_id, parent_component_id myschema.components comp inner join my_second_schema.component_parents related_comp on comp.id = related_comp.component_id order component_id;" > /tmp/it_component_parents.txt

the query runs long time , gets killed.

however if add limit 1000, query runs till end , output written in file.

i further investigated , found (using count(*)) total number of records returned 239553163.

some information server here:

mysql 5.5.27

    +----------------------------+----------+     | variable_name              | value    |     +----------------------------+----------+     | connect_timeout            | 10       |     | delayed_insert_timeout     | 300      |     | innodb_lock_wait_timeout   | 50       |     | innodb_rollback_on_timeout | off      |     | interactive_timeout        | 28800    |     | lock_wait_timeout          | 31536000 |     | net_read_timeout           | 30       |     | net_write_timeout          | 60       |     | slave_net_timeout          | 3600     |     | wait_timeout               | 28800    |     +----------------------------+----------+

here's state of query monitored :

    copying tmp table on disk     sorting results     sending data     writing net     sending data     writing net     sending data     writing net     sending data ...     killed

any guesses what's wrong here ?

the mysql client runs out of memory.

use --quick option not buffer results in memory.
