what about going the other way?
I'm familiar w/ sql server and not so much in mysql. Therefore if or when i have to work in mysql which isnt very ofter i try and use sql server to do it.
In this instance all that i have left is to insert my final results into a mysql db table using linked server. i just dont know how to do that. I'm using linked server and open query to pull down the original information. i make changes to it then need to reinsert my changed recs back into the mysql db table. I have everything done except the insert. Below are some more details.
linkserver: LOCALXML_Stage
Table whos contents in sql server that i'm trying to insert into mysql: LocalXMLclaimed_business_record
Table on mysql db i'm inserting into: localxml.claimed_business_record
Anyone know how to write this insert into mysql using linked sql and i suppose open query?

Has anyone tried doing an insert into the linked MySQL server from within a trigger?
An insert works fine if I execute it from the query window in SSMS but the same statement in a trigger gives the following error
Msg 7391, Level 16, State 2, Procedure update_trig, Line 7 The operation could not be performed because the OLE DB provider "MSDASQL" for linked server "MYSQL" was unable to begin a distributed transaction.
Someone suggested adding a COMMIT statement before the insert -
SET XACT_ABORT ON
COMMIT
INSERT INTO OPENQUERY(MYSQL, 'select data from db.test') values ('testing trigger')
This does do the insert in the linked MySQL server but gives the error that causes some problems with replication -
Msg 3609, Level 16, State 1, Line 1 The transaction ended in the trigger. The batch has been aborted.
If anyone has any suggestions, or if it is just not possible please let me know.

I had to spend a bit of time trying to set up a link server from SQL Server 2008 R2 to MySQL 5.5.14. Finally I made it.
The problem was the MySQL ODBC driver v5.1.8. After I went back to v 3.51.28 the linked servers started working. Then I had to pick the right options. Unfortunately MySQL/Oracle documentation of the options was incomplete and I had to read the C source code of the driver to figure out which options will I need. Here is my store procedure to set up a link server from SQL Server 2008 R2 to MySQL 5.5.14, you might like different options so I listed them all.
Cheers

As per your steps, I have created the linked server for MySQL in sql server management studio.
I can able to see the database and also the tables.
But i cant able to view the records and also i cant able to view/alter the table columns.
Is this any permission that i need to give.. and where to assign this..?
help plz...
February 17, 2012 at 3:09 am
the USerid and password you are using to connect to Mysql dont have appropriate permission
February 17, 2012 at 3:12 am
how and where to make that user permission in Linked server...?
February 17, 2012 at 3:19 am
This needs to be done at MYSQL server end, i never worked on MYSQL so cannot tell you how to create user or give permission at MYSQL. In my case MYSQL DBA in our company created a USerid and password and handed over to me.
February 17, 2012 at 3:26 am
ya i have mysql userid and password..when i used that credentials i cant able to create lincked server.
so what i do is , i created a new user in sql server and add that user to the linqed server.
i also tried to map the sql server user to mysql server user..its connecting.
but i didnt able to see tables columns...and fetch datas

This was really helpful guys. Thanks. But I am stuck with this error now
OLE DB provider "SQLNCLI" for linked server "MISSERVER" returned message "Login timeout expired".
OLE DB provider "SQLNCLI" for linked server "MISSERVER" returned message "An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections.".
Msg 53, Level 16, State 1, Line 0
Named Pipes Provider: Could not open a connection to SQL Server [53].
Please HELP !

I recently went to install the ODBC connector and create a linked server to MySQL as described here http://www.sqlservercentral.com/Forums/FindPost1332192.aspx. I ran into and solved 2 problems, so I figured I'd post them here.
1. You get this error when you try to create the DSN on a 64-bit machine connected to a 32-bit server:
The specified DSN contains an architecture mismatch between the Driver and Application". (Microsoft SQL Server, Error: 7303)
The solution is here http://msdn.microsoft.com/en-us/library/ms712362%28VS.85%29.aspx. Basically, you have to use the WOW64 version of the ODBC editor to create the DSN.
2. Once your DSN and linked servers are created, you can SELECT from the linked server, but you cannot INSERT or UPDATE. You get this error when you try:
OLE DB provider "MSDASQL" for linked server "mylinkedserver" returned message "Row cannot be located for updating. Some values may have been changed since it was last read.".
Msg 7343, Level 16, State 4, Line 1
The OLE DB provider "MSDASQL" for linked server "mylinkedserver" could not UPDATE table "[mylinkedserver]...[mytable]". The rowset was using optimistic concurrency and the value of a column has been changed after the containing row was last fetched or resynchronized.
This is apparently quite common, and I read at least 3 different fixes for it. The one that worked for me, however, was to edit the Cursors/Results tab of the DSN connection and check the box for "Return matched rows instead of affected rows"
Hope this helps someone else out,
Rich

Thanks a bunch! This was extremely helpful as I am not very versed in MySQL!
