sql错误＃1064不知道这是什么错误

Question

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 'CREATE TABLE Products( Category VARCHAR(30), Item VARCHAR(30),PRIMARY KEY, Pr' at line 2

   CREATE TABLE Products(
   Category VARCHAR(30),
   Item VARCHAR(30) PRIMARY KEY,
   Price DECIMAL(5,2),
   Quantity INT
   ) ENGINE=InnoDB;

Answer 1

CREATE TABLE Products(
Category VARCHAR(30),
Item VARCHAR(30),PRIMARY KEY, <-- The comma is your problem
Price DECIMAL(5,2),
Quantity INT
) ENGINE=InnoDB;

To assign PK to a column, it should be:

CREATE TABLE Products(
Category VARCHAR(30),
Item VARCHAR(30) PRIMARY KEY,
Price DECIMAL(5,2),
Quantity INT
) ENGINE=InnoDB;
