I try the following statement to add another row and I'm getting the following error:

ERROR 1136 (21S01): Column count doesn't match value count at row 1

Here are the ways I've tried to insert the row into the table:

insert into table (Field, Type, Null, Key, Default, Extra) VALUES ("contract_expiration", "date", "YES", "", "NULL", "");

insert into table VALUES ('contract_expiration','date','YES','','NULL','');

Both return the same error. There are no triggers on the table, I'm not sure what's going on.

Any suggestions? I'm relatively new to mysql administration, I know a bit but this has me stumped and searches for solutions have turned up nothing.

Any help that could be provided would be MUCH appreciated!

Answer 1

NULL is not a valid field name in:

insert into `table`(Field, Type, Null, Key, Default, Extra) 
    VALUES ("contract_expiration", "date", "YES", "", "NULL", "");

And Key and default are reserved words. Try this:

insert into `table`(Field, `Type`, `Null`, `Key`, `Default`, Extra) 
    VALUES ("contract_expiration", "date", "YES", "", "NULL", "");

Answer 2

I had a similar case, where I took the table definition from a dev server and the data from a live server, and it turned out that they were actually not quite the same.

The way I found out the difference was (there are probably smarter ways to do it, but this is how I did it):

SHOW CREATE TABLE mytable;

I ran this on all 3 cases (live database, dev database, and new database I created using CREATE TABLE xxx like xxx ).

Then I simply compared the 3 and found that the live and dev had a different set of columns, so I simply ran

 ALTER TABLE xxx DROP yyy; 

until the new table was the same as the table the dump was from; then I could import data.

mysql> desc classroom;

| clFName | varchar(30) | NO   |     | NULL    |                |
| clSName | varchar(10) | NO   |     | NULL    |                |

mysql> select * from classroom;

|    1 | Classroom1 | cl1     |    100 |

|    4 | 3f         | 3s      |      3 |
|    5 | class4     | class4  |    100 |
+------+------------+---------+--------+
5 rows in set (0.00 sec)

I also have same error

mysql> insert into classroom values('Gudadhe', 'Akash', 20);
ERROR 1136 (21S01): Column count doesn't match value count at row 1

This error can be solved by specifying column names before inserting directly as follows

By writing classroom(clFName, clSName, clCapc) we are specifying columns into which we want to insert values

mysql> insert into classroom(clFName, clSName, clCapc) values('Gudadhe', 'Akash', 20);
Query OK, 1 row affected (0.06 sec)
