創建表在SQLyog的失敗

Question

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

誤差

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) 
); 

這個工作。我刪除了IDENTITY。 I do not see IDENTITY in the create table doc of MySQL.

EDIT1（得到了OP的從T-SQL輸出錯誤的語法）

啊我明白了...你正在服用的T-SQL的SQL？ Perhaprs你需要自動增量使用這個

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

Answer 2

我想你想使用AUTO_INCREMENT。試試這個：

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