Hi.

Let's say i have TABLE-1 in mysql-server1 with 2 columns :

id PRIMARY auto-increment.
name TEXT

In TABLE-1 i have 2 rows

id  name
1   JOHN
2   MIKE

If i make an export of TABLE-1 in mysql-server2 with mysqldump, i get a file that contain
INSERT INTO TABLE-1 VALUES (1,'ROBERT');
INSERT INTO TABLE-1 VALUES (2,'JASON');


How could I do to import data from mysql-server2 without having problem with "DUPLICATE KEY" of id.

Can i get this export with mysqldump, typing a specific option ?? : (that would solve my problem)
INSERT INTO TABLE-1 VALUES ('','ROBERT');
INSERT INTO TABLE-1 VALUES ('','JASON');

Or do i need to do something while importing.


My real world table have many columns and about 600Mb of data, so i need an adapted solution.

Thanks

HI,

Make a backup of the database before doing anything here..

I guess your import file is something like this.. say dump.sql .. and make sure the autoincrement column looks like ''

INSERT INTO TABLE-1 VALUES ('','ROBERT');
INSERT INTO TABLE-1 VALUES ('','JASON');
then use this command to insert/import..

mysql -u USER -p DBNAME < dump.sql
