PHP-自动生成 MySQL 创建 Table 语句 returns 错误

Question

mysql> CREATE TABLE metadata 
( 
id int, 
created_by int, 
modified_by int, 
deleted_by int, 
created_at datetime, 
modified_at datetime, 
deleted_at datetime, 
key varchar(45), 
definition_type varchar(1), 
metadata_type varchar(1), 
no_of_decimals int, 
is_required tinyint, 
min_range decimal, 
max_range decimal, 
entity varchar(10), 
sequence int, 
meta_group varchar(2), 
PRIMARY KEY (id) );

ERROR 1064 (42000): 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 'varchar(45), definition_type varchar(1), metadata_type varchar(1), no_of_decimal' at line 1

我不太确定如何更正此错误，因为此类问题通常不会在网上提供具体答案。我该如何解决这个错误？

Answer 1

key是保留字，在MySQL:

中用反引号`转义

`key` varchar(45)
