sql - mysql 时间戳语法错误

Question

我有这段 SQL 正在被输入到 Mysql。

CREATE TABLE pn_history(
 member INT,
 action INT,
 with INT,
 timestamp DATETIME,
 details VARCHAR(256)
)

但是返回的语法错误。

#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 'with INT,
timestamp DATETIME,
details VARCHAR(256)
)' at line 4 

为什么会失败？

Answer 1

“with”和“timestamp”都是reserved words在 MySQL 中。因此，要使其正常工作，您需要转义每一个:

CREATE TABLE pn_history(
 member INT,
 action INT,
 `with` INT,
 `timestamp` DATETIME,
 details VARCHAR(256)
)

实际上，您需要考虑更改列的名称 identifiers .

编辑:实际上，TIMESTAMP不是保留字。文档说:

MySQL allows some keywords to be used as unquoted identifiers because many people previously used them. Examples are those in the following list:

• ACTION
• BIT
• DATE
• ENUM
• NO
• TEXT
• `TIME
• TIMESTAMP

所以我猜这意味着同行压力将 TIMESTAMP 从保留字列表中删除了。哈!
