The max_execution_time setting is too small.

Recurrence:

Set max_execution_time to a small value and execute mysqldump (essentially SELECT) or SELECT:

[17:23:01] root@localhost [(none)]> SET GLOBAL max_execution_time=10;

Query OK, 0 rows affected (0.00 sec)

[17:23:11] root@localhost [(none)]> SELECT * FROM test.t1 LIMIT 100000;

ERROR 3024 (HY000): Query execution was interrupted, maximum statement execution time exceeded

mysqldump -uxxx -pxxx -S -A > /tmp/a.sql

mysqldump: Error 3024: Query execution was interrupted, maximum statement execution time exceeded when dumping table `$tb_name` at row: 0

Solution:

① Increase the value of N through hints (the document says that in the use of hints, change N to 0 for unlimited, but I measured it does not take effect, can be set to a larger value such as 99999 solution)

SELECT /*+ MAX_EXECUTION_TIME(N) */ * FROM t1 LIMIT 100000;

② Modify the max_execution_time value, set it to a higher value, or set it to 0 (unlimited)

Related parameters:

max_execution_time

This parameter 5.7.8 was added in ms, dynamic parameter, default is 0.

When set to 0, it means SELECT timeout is not set (no timeout is limited).

Does not work on SELECT statements in stored procedures, and only works on read-only SELECT, such as INSERT... SELECT ... It's not going to work.

At this point, the study of MySQL error mysqldump Error 3024: Query execution was interrupted is over, hoping to solve everyone's doubts.
