You may get tis value, if you are missing the value for auto_increment column. The error is as follows −
mysql> insert into DemoTable1353 values('Chris',23); ERROR 1136 (21S01): Column count doesn't match value count at row 1
You need to provide the value for auto_increment or leave it to automatic generation.
Let us see an example and create a table −
mysql> create table DemoTable1353 -> ( -> Id int NOT NULL AUTO_INCREMENT, -> Name varchar(20), -> Age int, -> PRIMARY KEY(Id) -> ); Query OK, 0 rows affected (0.52 sec)
Insert some records in the table using insert command. We haven’t inserted auto increment value and it will generate on its own −
mysql> insert into DemoTable1353(Name,Age) values('Chris',23); Query OK, 1 row affected (0.30 sec) mysql> insert into DemoTable1353(Name,Age) values('David',21); Query OK, 1 row affected (0.12 sec) mysql> insert into DemoTable1353(Name,Age) values('Bob',24); Query OK, 1 row affected (0.13 sec) mysql> insert into DemoTable1353(Name,Age) values('John',47); Query OK, 1 row affected (0.11 sec)
Display all records from the table using select statement −
mysql> select * from DemoTable1353;
This will produce the following output −
+----+-------+------+ | Id | Name | Age | +----+-------+------+ | 1 | Chris | 23 | | 2 | David | 21 | | 3 | Bob | 24 | | 4 | John | 47 | +----+-------+------+ 4 rows in set (0.00 sec)
