为什么这个SQL UPDATE查询不起作用？

Question

I know SQL well but I must be missing something really dumb here. This update query keeps throwing an error. The query is:

UPDATE pages SET 'order' = 1 WHERE id = 19

The table definitely has a column for order, and it has a record with the ID of 19. The order column is not unique.

The error I get is the generic one:

#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 '"order" = 2 WHERE id = 19' at line 1 

I've enclosed order in quotation marks because ORDER is a reserved SQL word. What am I missing?

Answer 1

如果使用MySQL，查询应如下所示：

UPDATE `pages` SET `order`=1 WHERE `id`=19

Answer 2

That looks like a MySQL error message. Doesn't MySQL use backticks (`) for escaping?

Answer 3

UPDATE pages SET [order] = 1 WHERE id = 19

Nevemind MySQL

Answer 4

don't use quotes, use [order] (or whatever your sql version uses for escaping). With the regular quotes it is seen as a string literal, which is not allowed here.

Answer 5

The simplest answer is;

UPDATE pages SET pages.order = 1 WHERE id = 19 ;

That should do the trick.

Answer 6

您需要从查询中的列名称规范中删除单引号

UPDATE pages SET order = 1 WHERE id = 19 ; 

Answer 7

order is a reserved word used in ORDER BY .

Use backticks (`) (as Ken said).

Answer 8

I think the query should be;

UPDATE pages SET order = '1'
WHERE id = 19
