Question

I am looking for a solutions for my MySQL data copying related problem.
I have a table TAB1 in a database DB1 that contains some data. Now I want some of these data rows to be migrated to another table TAB2 to some another database DB2.

What would be an ideal way to write such a SQL script for MySQL server. I cannot write java/php program etc because I don’t have access to the code base.

Any example links will be helpful. I know this can be done in Oracle via DBLink but how to do it in MySQL.

Thanks

Answer 1

insert into db2.table2 (field1,field2,..,fieldN)
select field1,field2,..,fieldN from db1.table1

EDIT. If you need to do an update between two different databases this is the right syntax:

update 
db2.table2 as t2,
db1.table1 as t1
set 
t2.field1 = t1.field1,
t2.field2 = t1.field2,
t2.field3 = t1.field3
where t1.id = t2.id
