I have a local SQL Server database with many tables. I need to transfer data to a remote SQL Server database using vb.net, and task should be run every 2 hr from application. How is it possible to do this? Please suggest the best way for this.
I think the better way is replication. i don't know the possibilities in SQL Server but it works great in mysql. if you enables the replication in two database(Master- Slave) what ever be the changes you have made in the master will simultaneously in the slave. there is possibilities for Bi-Directional Replication in MySQL.
SQL Server provides various types of replication to extend the possibilities. this article helps you to establish replication in Sql Server

I need to transfer data from one SQL server db to another SQL server db (limited tables) on different servers , I want to avoid transaction replication due to bad experiences already.
What are the alternate approaches to move data near real time in sql server.
Thanks.
We have a server with SQL database (8 database) working in LAN, Now we are planning to make a backup server connected through LAN.
What we need is, when user enter data it should save in both database, so that we have all the data in both database.
I am a newbie so pls give me some detail information. I have seen some replication option, is it better option for us.
We have SQL Server 2005.
Which database engine are you using?
There're several ways to build a distributed/replicated database, I'm sure you'll find out how to do it by reading your engine documentation, but we cannot help here without more info.
Yes, you can backup your database from one server to other by multiple way.. Following are those
1) Make script of complete database with schema and data..Technique is here
2) Export your database to excel file and import it to other server (Use only in required conditions).
3) communicate two server by addlink.. Technique here
Now if you want dump data in two different server then its depend on code logic written for dumping database and connection string provided for it. By adding Trigger to one server database you can dump data on different server or database.. Trigger
I have a database Now what I want If in any case my database server
has failed then it automatically gets data from another server. I want
to know how can we do Data Replication/Mirroring.
Can anybody share an idea how we can do this?
I have searched a lot in the Google but doesn't get exact link for the
Data Replication on SQL Server 2012. I really appreciate your
suggestions.
For failover type scenarios, you want to use either Mirroring or Always on, not replication.
Details on Mirroring are available here:
Database Mirroring
Details on Always On are available here:
SQL 2012 Always On
Both of these solutions are able to provide automatic failover for applications to a separate copy of the database if the primary server fails, AlwaysOn is the better solution (and mirroring is now apparently deprecated as of SQL 2012) but has some more complex requirements such as a dependency on windows clustering.
Documentation for SQL Server Replication can be found in Books Online for SQL Server 2012 - SQL Server Replication.
I want to setup replication between SQL Server and MySQL, in which SQL Server is the primary database server and MySQL is the slave server (on linux).
Is there a way to setup such scenario? Help me .
My answer might be coming too late, but still for future reference ...
You can use one of the heterogeneous replication solutions like SymmetricDS: http://www.symmetricds.org/. It can replicate data between any SQL database to any SQL database, altough the overhead is higher than using a native replication solution.
of course you can replicate MSSQL database to MYSQL
By using Linked Server in MSSQL.
for that you need to download ODBC drivers. and you can further search regarding how to create Linked server on SQL SERVER.
This option is very easy and Totally free. You can use OPEN QUERY FOR THIS.
By using SSIS Packages.
for that you need the Business Intelligence service of SQL SERVER. you can create SSIS Packages on Visual Studio and run them for replication.
No. At least not without doing a lot of dirty, bad things. MSSQL and MySQL speak different replication protocols, so you won't be able to set it up natively (which is the way you'd want to handle it). At best, you could hack together some sort of proxy that forwards insert/update/delete/create/alter, etc. queries from one to the other. This is a terrible idea as they don't speak the same SQL except in the most common case. Even database dumps which wouldn't really be replication are generally incompatible between vendors.
Don't do it. If you must use different OSes on your servers, standardize the database to something that runs on both.
These two databases are from two different vendors. While I cannot say for sure, it is unlikely Microsoft has any interest in allowing replication to a different vendor's database server.
I work with Informix and MySQL. Both those databases have commands that dump the entire database to an ascii file format. You would need to see how that is done on MS SQL Server; ftp the dump to the server hosting the MySQL server; and then convert the dump into something MySQL can import.
I have 2 big tables in sql server that i need to sync to mysql.
now, i need that as an ongoing process.
the tables are 1 GB each and getting new/update/delete row every 0.1 second.
Can you recommend me a tool that can do it that is not resource expensive.
you can offer OPEN SOURCE and commercial as well
Thanks
You could create a linked server instance in SQL Server, pointing to the MySQL instance. This article gives the step-by-step process. Once that is in place, providing you grant the MySQL user you connect on behalf of proper permissions, you can write to the MySQL instance as you like. So you could easily update stored procedures to do an additional step to insert records into MySQL.
