mysql - 在 sqlog 中创建表失败

Question

CREATE TABLE inventory
(
   id INT IDENTITY(1,1) PRIMARY KEY,
   product VARCHAR(50) UNIQUE,
   quantity INT,
   price DECIMAL(18,2)
);

错误是

Error Code : 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 'IDENTITY(1,1) PRIMARY KEY,
   product VARCHAR(50) UNIQUE,
   quantity INT,
   pr' at line 3

Answer 1

CREATE TABLE inventory
(
   id INT PRIMARY KEY,
   product VARCHAR(50) UNIQUE,
   quantity INT,
   price DECIMAL(18,2)
);

这行得通。我删除了IDENTITY. 我在 MySQL 的创建表文档中没有看到IDENTITY。

EDIT1（从 T-SQL 导出了 OP 的错误语法）

啊，我明白了...您是从 T-SQL 获取 SQL 吗？也许你需要自动增量使用这个

CREATE TABLE inventory
(
   id INT AUTO_INCREMENT PRIMARY KEY,
   product VARCHAR(50) UNIQUE,
   quantity INT,
   price DECIMAL(18,2)
);

Answer 2

我想你想用AUTO_INCREMENT. 尝试这个：

CREATE TABLE inventory
(
   id INT AUTO_INCREMENT PRIMARY KEY,
   product VARCHAR(50) UNIQUE,
   quantity INT,
   price DECIMAL(18,2)
);
