I have 2 servers running mysql and they have the same database/table, but with different entries. There was a reason for that, but now I need to merge these databases. I've made a dump of the whole database in server 1 and I want to insert these data into the database of server 2. The problem is: How do I insert this data just incrementing the database of server 2? I can't lose the data that already is on server 2.

I have to copy tables from Database 1 at 'x' instance to another database which is empty right now on instance 'y' in SQL Server 2008.
How can I achieve this ?
You could create a linked server on the instance that you are importing data into. You will need to link the server that you are exporting data from. Here are a couple of links on how to set that up.

Calling Linked Server In Query
Once you have the linked server set up, you could do this:
INSERT INTO yourtable --table you are importing data into
SELECT *
FROM [server].[database].[schema].[table] --server you are exporting data from

I have an old system with sql server database. And I have to create a webiste with mysql database. The old system is still in use and is inserting data to the sql server DB everyday. So, I am thinking write a program that automatically transfer data from the sql server DB to the mysql DB. Any good suggestions? Thanks.
You have an active SQL Server database.
Unless you are planning to decommission this database server (for very good reasons not related to this new application), then the new application should simply query this server.
You can create a small (Maybe in c#) program that keeps running all the times with a timer, and on this timer, get all rows from SQL server that are not marked as "Copied", insert them on MySQL and the update those rows as "Copied". That program need to have access to both databases.
I was looking into how to do a query between 2 database on different servers.
I am trying to select another database from another server and insert into my local server.
I am trying to migrate tables with different schema so I have to build its design to be identical to the new design before inserting.
Any suggestions? I was checking Federated but it required me to change the database engine on the remote server w/c I didn't want to do.
So, is this possible? If not, then I'll just use python to migrate and connect between 2 servers.
How can I configure MySQL to replicate a table to another server without writing the table on the first server? Can I write binary log but not commit the changes to the local table?
EDIT
I want to automatically (not one time) export all data inserted to a table to another mysql server, but to improve performance, I don't want to write the data to the master server, I want to directly send it to another server.
This can be achieved through standard replication. Just use the BLACKHOLE storage engine on the master server.
