Inserting empty string on Windows MySQL doesn't use default value

Question

Why inserting '' on a column with default integer value on MYSQL/WINDOWS produces ERROR 1366 (HY000): Incorrect integer value: '' for column 'id' at row 1

The query is:

insert into test2 (id,test) values('','');

If I use this query on MYSQL/LINUX, it runs just fine:

mysql>  insert into test2 (id,test) values('','');
Query OK, 1 row affected, 2 warnings (0.01 sec)

mysql>

id is autoincrement test column is INT and has default value 0

Thanks.

SOLUTION: on my windows machine i disable "strict" mode in my.ini file, i removed STRICT_TRANS_TABLES from sql-mode=

Answer 1

PROBLEM

You need to insert nothing ?

SOLUTION

Then, insert nothing at all ... literally !!!

One of the following will work

INSERT INTO test2 () VALUES (),(),();
INSERT INTO test2 (test) VALUES (NULL),(NULL),(NULL);
INSERT INTO test2 (id) VALUES (NULL),(NULL),(NULL);

SAMPLE DATA

use test
DROP TABLE IF EXISTS test2;
CREATE TABLE test2
(id int not null auto_increment primary key,
test int not null default 0);
SHOW CREATE TABLE test2\G
SELECT * FROM test2;

SAMPLE DATA LOADED

mysql> use test
Database changed
mysql> DROP TABLE IF EXISTS test2;
Query OK, 0 rows affected (0.11 sec)

mysql> CREATE TABLE test2
    -> (id int not null auto_increment primary key,
    -> test int default 0);
Query OK, 0 rows affected (0.34 sec)

mysql> SHOW CREATE TABLE test2\G
*************************** 1. row ***************************
       Table: test2
Create Table: CREATE TABLE `test2` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `test` int(11) NOT NULL DEFAULT '0',
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1
1 row in set (0.00 sec)

mysql> SELECT * FROM test2;
Empty set (0.00 sec)

mysql>

QUERIES EXECUTED

If id and test are the only two columns in the table, the INSERT does not need a column list. If there are other columns in test2 besides id and test, name the test column and insert a NULL. Keep in mind, inserting a NULL into a column that has DEFAULT 0 will become 0.

mysql> SELECT * FROM test2;
Empty set (0.00 sec)

mysql> INSERT INTO test2 () VALUES (),(),();
Query OK, 3 rows affected (0.03 sec)
Records: 3  Duplicates: 0  Warnings: 0

mysql> INSERT INTO test2 (test) VALUES (NULL),(NULL),(NULL);
Query OK, 3 rows affected, 3 warnings (0.06 sec)
Records: 3  Duplicates: 0  Warnings: 3

mysql> INSERT INTO test2 (id) VALUES (NULL),(NULL),(NULL);
Query OK, 3 rows affected (0.06 sec)
Records: 3  Duplicates: 0  Warnings: 0

mysql> SELECT * FROM test2;
+----+------+
| id | test |

CAVEAT #1 : I did this in Windows 8.1 from the command line

mysql> select * from information_schema.global_variables
    -> where variable_name like 'version%';

CAVEAT #2 : I am using MySQL's default SQL mode. Thus, I did not need to disable anything.

Answer 2

loading empty values by a date file will insert the data with empty strings instead of NULL. I solved my case loading the data into tekst fields and subsequently ran an update: update table <> set col1=NULL where col1='';
