MySQL error Query execution was interrupted, maximum statement execution time exceeded

MySQL 查詢時，報如下錯：
Query execution was interrupted, maximum statement execution time exceeded

查詢數據庫最大語句執行時間,默認為10s，單位是毫秒

SELECT @@global.max_execution_time

設置最大執行時間, 設置為30s

SET global max_execution_time = 30000;
