难以在 mysql 数据库中创建 table

Question

我尝试在 mysql 数据库中手动创建一个 table，其中包含列 id、phone、电子邮件、密码、paymwnt。这里的id是PRIMARY KEY自增但是当我点击保存的时候，显示如下错误信息

incorrect prefix key. The used part isn't a string, the used length is longer than the key part or storage engine does not support unique prefix keys"

有人请帮助。

Answer 1

'payment' 是浮动的吗？

请尝试：

CREATE TABLE table_name ( id INT NOT NULL AUTO_INCREMENT , phone VARCHAR(16) NOT NULL , email VARCHAR(128) NOT NULL , password VARCHAR(64) NOT NULL , payment FLOAT NOT NULL , PRIMARY KEY (id))

If possible, please respond with your full mysql query so I check the error.

Answer 2

CREATE TABLE #USER_TABLE 
(
Userid int PRIMARY KEY identity(1,1), 
Last_Name varchar(50), 
First_Name varchar(50)
);
select * from #USER_TABLE
insert into #USER_TABLE values('k','Raj')

太阳:

Userid  Last_Name   First_Name
1           k         Raj
