how to insert data into table in MySQL

Question

i created this table

create table courses (
cid int primary key not null,
cname varchar(25) )

and when i tried to insert any thing like that

insert into courses values (1,name)

i have this error

insert into courses values (1,`ahmed`)

Error Code: 1054. Champ 'ahmed' inconnu dans field list 0.000 sec

when i try to add only cid it's ok , i removed the table and created it twice and the same problem

what is the wrong thing here?

Answer 1

You need to delimit your varchar values with single quotes ( ' ).

Try the following instead:

insert into courses values (1,'ahmed');

Numerics can be passed without the single quotes, however any char or varchar derived types need the single quotes. Look up datatypes for SQL for further information.

Answer 2

Put Single quote (') for string values

Try this:

INSERT INTO courses (cid, cname)
VALUES (1, 'ahmed');
