I am using MSSQL as my transactional database. This database has 200+ tables with about 25 tables that hold 1M plus records. I want to replicate the data with the same structure into a MySql database for reporting. Is there a tool or method that can do this in a fairly real time manner?
Use SQL Server's Linked Server to access MySQL from SQL Server.

I have a SQL server DB, a Oracle DB, a MySQL DB. I have a way to join the tables from each DB. How would be the best way to create this view? I have just started SSIS project that pulls the tables from the DBs and creates the view I want, but is there a way to grab the data from each engine in the view in real-time\dynamic?
Thr best way to do that is to create a linked server for each instance (Oracle, MySQL) on sql server without the need to copy data.
And then you can create a view that join the tables between instances.

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.

Replication from MySQL to MS SQL
i have one MySQL server.
in that server there are the 15 databases and i need to sync the data to MsSQL to MySQL and the condition is a data transmit only MsSQL to MySQL on every update. so please guide me how to perform this task and how to set cron job.
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 a big database around 46GB in Mysql format and I managed to convert all the database to MSsql except two tables, the biggest ones. When I try to migrate those 2 tables, one by one , after a while I get the error message "The connection has been disabled"
I encreased the timeout from SSMA option from 15 to 1440 and decreased the bash from 1000 to 500 and same thing, The tables have 52 mil rows and 110 milion rows with 1,5 GB and 6.5 GB.
I tried incremential version but I don't have a unique id to use
What can I do to migrate them
Thank You
You should be able to use SQL Server Integration Services (SSIS). You can create a dataflow that pulls from MYSql and dumps the Data into MSSQL.
You'll need to create a Data flow task that includes an OLE Database Source and connect it to an OLE Database Destination.
I had the same problem using SSMA. I managed to migrate 100+ million rows of a table with 40+ columns.
I assume you've done the configuration well.
You need to ensure that there is no activity in the MSSQL database. No SELECTS over those tables and no any other activities.
Check out the two tables' structures to ensure they are fine. You can run the SSMA project only for those two tables.
Hope this helps.
I had the same issue and fixed by using the following configuration described here in detail: MySql 5.6 to MSSql server 2014 migration : ExecuteReader requires an open and available Connection
Also, I have documented the whole MySQL to MSSQL migration process here: Migrate Data and Schema from MySQL to SQL Server
