问题描述
我有一个表,其列名有 25、50、100 等.
I have a table that has column names like 25, 50, 100, etc..
尝试更新表格时,无论我如何操作,都会出现错误
When trying to update the table I get an error, no matter how I do it
UPDATE table SET '25'='100' WHERE id = '1'
我尝试过以任何方式引用和反引号,但没有成功.
I have tried quoting and backticking every which way but without success.
错误总是沿着以下路线:
The error is always along the lines of:
您的 SQL 语法有错误;检查与您的 MySQL 服务器版本相对应的手册,以获取在第 1 行的25"=100 WHERE id=1' 附近使用的正确语法
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 ''25'=100 WHERE id=1' at line 1
如果我将列名更改为 twentyfive
- 我没有问题,但这不是我想要的.是否可以使用数字作为列名?
If I change the column name to twentyfive
- I don't have a problem, but that's not what I want. Is it possible to use a number as a column name?
推荐答案
来自 文档:
标识符可以以数字开头,但除非引用,否则不能仅由数字组成.
Identifiers may begin with a digit but unless quoted may not consist solely of digits.
这意味着你必须用反勾号来引用它,比如25":
Which means you must quote it with back ticks like `25`:
UPDATE table SET `25`='100' WHERE id='1'
