We have created a MS SQL Linked server for a MYSQL database...I have a data replication questions related to linked server
1.Once a MS SQL Linked server is created between MYSQL and MS SQL,if we insert any new data into existing tables of MYSQL,does the data get automatically replicated to the MSSQL Linked server?
2.If we add new tables or columns how to data replication is handled between MYSQL and MS SQL linked server?is there an automated way to replicate data?
A linked server in SQL server simply provides you the capability to issue commands against a remote server. It does not mean any kind of replication will happen automatically for schema or data. As to how to actually accomplish replication between SQL Server and MySQL, the question has been asked and answered many times. As far as I know you will need to use a third party framework or roll something of your own via ETL, triggers, etc.

I have two different application which run on different database, SQL Server and MySQL. Now I want real time data sync between SQL Server and Mysql - can anybody please tell me. I have already tried data migration, but it copies only data not sync data
Take a look at StreamSets. Open source and can read the SQL Server change tracking (CT) tables and turn them into inserts, updates, and deletes to any database with a JDBC driver including MySQL. It can also use the MySQL binlog to build data pipelines in the other direction.
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 have similar schema in both MySQL and MSSQL Server databases. How can I migrate just the data from MySql to an empty (no data) MSSqlServer database? MSSqlServer DB is empty with just the schema. I could not configure the MySql DB as a linked server (through ODBC) since I don't have DB Admin rights on MSSqlServer. I just have previleges to add data. I explored Sql Server Migration Assistant for MySQL, but I just want to migrate data without touching the schema at the target.
I also noticed that there is a SqlBulkCopy class which helps to programatically migrate data in .NET.
But I need to write code for each table (there are more than 100 tables and 20 GB of data).
What is the most elegant way to do it?
SSMA might be the easiest. Since you don't wanna use that, you can try using mysqldump. You can use it to essentially dump a MySQL db to SQL Server.
Link to the SSMA blog, they update these tools regularly, so check for a later version. SQL Server Migration Assistant (SSMA) Team's Blog
I need to access a remote Microsoft SQL Server database from a stored procedure in MySQL database.
I googled and found that there is a way to access a remote MySQL using federated tables. But I couldn't find anyway to do access MS SQL Server. My exact requirement is, I need to write a stored procedure which can duplicate all the tables and data from a remote MS SQL server database to a local MYSQL database.
Please help..
In short this cannot be done with MySQL federated engine. However you can setup a link from the remote MSSQL server to a MySQL table using the linked server feature of the MSSQL server.
If you can set this up you can have a scheduled job populate the MySQL tables from the MSSQL server side.
I have done the above setup and it is not to difficult.
I would also investigate some ETL tool to do this as it sounds like a ETL job and not something you want to run via stored procedures.
Good Luck.
I am using an open source software which support mysql and i create application that uses asp.net 4.0 and sql server 2008....
Is it possible to Connecting MYsql with sql server ?

kindly explain step by step if possible
hope this will help,this shows step by step connection

You can use linked server in MS SQL Server.
From the documentation - A linked server allows for access to distributed, heterogeneous queries against OLE DB data sources.
Have a look at sp_addlinkedserver function.
