Error Code: 1054 in mySQL

Question

I created a table in mySQL database 'payroll' as:

CREATE TABLE `users` (
`userName` varchar(15) NOT NULL,
`password` varchar(15) NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

I'm getting error

1054(Unknown column 'Imran' in the 'field list')

on following line of code:

insert into payroll.users SET userName=Imran

Answer 1

Imran单词应该用'-s封装，以表示它是一个字符串。

insert into payroll.users SET userName='Imran'
