Question

有人能告诉我为什么我的语法错了吗？

我将分隔符设置为$$ do prevent;成为一个问题。我不想创建表格，截断是好的。

DELIMITER $$
create procedure create persistent_views
begin

truncate table vwt_total_overview_last3days;
truncate table vwt_total_overview_last30days:
truncate table vwt_total_overview_last7days;
truncate table vwt_total_overview_lastday;

insert into vwt_total_overview_last3days
select * from total_overview_last3days;

insert into vwt_total_overview_last30days
select * from total_overview_last30days;

insert into vwt_total_overview_last7days
select * from total_overview_last7days;

insert into vwt_total_overview_lastday
select * from total_overview_lastday;

END $$

我得到了：

#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'create persistent_views begin truncate table vwt_total_overview_last3days; trun' at line 1

我将声明更改为以下内容，但它也无效（尝试使用和不使用parens和AS）

DELIMITER $$
create procedure persistent_views() AS 
begin

truncate table vwt_total_overview_last3days;
truncate table vwt_total_overview_last30days:
truncate table vwt_total_overview_last7days;
truncate table vwt_total_overview_lastday;

insert into vwt_total_overview_last3days
select * from total_overview_last3days;

insert into vwt_total_overview_last30days
select * from total_overview_last30days;

insert into vwt_total_overview_last7days
select * from total_overview_last7days;

insert into vwt_total_overview_lastday
select * from total_overview_lastday;

END $$

Answer 1

您已使用CREATE字两次。只需删除第二个。这可能会解决你的问题。之后是一对paranthesis和AS关键字。

Answer 2

好的，我自己解决了。一个半结肠，实际上是结肠......

正确的语法是：

DELIMITER $$
create procedure persistentViews() 
BEGIN
truncate table vwt_total_overview_last3days;
truncate table vwt_total_overview_last30days;
truncate table vwt_total_overview_last7days;
truncate table vwt_total_overview_lastday;

insert into vwt_total_overview_last3days
select * from total_overview_last3days;

insert into vwt_total_overview_last30days
select * from total_overview_last30days;

insert into vwt_total_overview_last7days
select * from total_overview_last7days;

insert into vwt_total_overview_lastday
select * from total_overview_lastday;
END $$
