Question

MySQL is issuing this error when I try to execute a query where the column count does match. Here is the structure of the table:

mysql> desc S_3068; 
+-------------------+----------------------+------+-----+---------+-------+ 
| Field             | Type                 | Null | Key | Default | Extra | 
+-------------------+----------------------+------+-----+---------+-------+ 
| SfmID             | smallint(5) unsigned | NO   | PRI | 1       |       | 
| DatValue          | float                | NO   |     | 0       |       | 
| DatRawValue       | int(10) unsigned     | NO   |     | 0       |       | 
| DatTime           | int(10) unsigned     | NO   | PRI | 0       |       | 
| DatBusOrder       | tinyint(3) unsigned  | NO   | PRI | 1       |       | 
| DatFormulaVersion | tinyint(3) unsigned  | NO   |     | 0       |       | 
+-------------------+----------------------+------+-----+---------+-------+ 
6 rows in set (0.00 sec) 

I get the aforementioned error when I execute this query:

mysql> insert ignore into S_3068 values (133, 15.82, 5542, 1339309260, 0, 1); 
ERROR 1136 (21S01): Column count doesn't match value count at row 1 

As you can see, the column count does match the value count. Now what’s even more puzzling is that the query works perfectly fine with SfmID = 132:

mysql> insert ignore into S_3068 values (132, 15.82, 5542, 1339309260, 0, 1); 
Query OK, 1 row affected (0.00 sec) 

SfmID being a unsigned smallint, that doesn’t make any sense to me.

Any help on this matter would be greatly appreciated.

EDIT: The error was caused by a trigger associated to the table. Please see comments for more information.

Answer 1

The error was caused by a trigger associated to the table, doing a side insert on another table for value 133 but not for value 132. The error issued by MySQL was about the other table (which column count was indeed wrong) and not about the main table in which I was inserting data.
