MySQL創建臨時表

Question

無法理解為什么此創建臨時表不起作用..有人可以建議..嗎？

create temporary table if not exists table2 AS (select unix_timestamp(concat(delivery_date, ' ', str_to_date(delivery_time,'%h:%i%p'))) as timestamp, id from fruit.order_delivery_orders where calendar_id is not null);

它得到一個錯誤“查詢被中斷”。

此查詢工作正常-

select unix_timestamp(concat(delivery_date, ' ', str_to_date(delivery_time,'%h:%i%p'))) as timestamp, id from fruit.order_delivery_orders where calendar_id is not null

Answer 1

請使用以下語法。 希望這對您有幫助。

 CREATE TABLE [ IF NOT EXISTS ] table_name AS SELECT column_names FROM table_name_2 WHERE condition;
