Linked Server To MYSQL Using OLEDB Provider For MYSQL Cherry

Feb 12, 2007

Good Morning

Has anyone successfully used cherry's oledb provider for MYSQL to create a linked server from MS SQLserver 2005 to a Linux red hat platform running MYSQL.

I can not get it to work.

I've created a UDL which tests fine. it looks like this

[oledb]

; Everything after this line is an OLE DB initstring

Provider=OleMySql.MySqlSource.1;Persist Security Info=False;User ID=testuser;

Data Source=databridge;Location="";Mode=Read;Trace="""""""""""""""""""""""""""""";

Initial Catalog=riverford_rhdx_20060822

Can any on help me convert this to corrrect syntax for sql stored procedure

sp_addlinkedserver

I've tried this below but it does not work I just get an error saying it can not create an instance of OleMySql.MySqlSource.

I used SQL server management studio to create the linked server then just scripted this out below.

I seem to be missing the user ID, but don't know where to put it in.

EXEC master.dbo.sp_addlinkedserver @server = N'DATABRIDGE_OLEDB', @srvproduct=N'mysql', @provider=N'OleMySql.MySqlSource', @datasrc=N'databridge', @catalog=N'riverford_rhdx_20060822'

GO

EXEC master.dbo.sp_serveroption @server=N'DATABRIDGE_OLEDB', @optname=N'collation compatible', @optvalue=N'false'

GO

EXEC master.dbo.sp_serveroption @server=N'DATABRIDGE_OLEDB', @optname=N'data access', @optvalue=N'true'

GO

EXEC master.dbo.sp_serveroption @server=N'DATABRIDGE_OLEDB', @optname=N'dist', @optvalue=N'false'

GO

EXEC master.dbo.sp_serveroption @server=N'DATABRIDGE_OLEDB', @optname=N'pub', @optvalue=N'false'

GO

EXEC master.dbo.sp_serveroption @server=N'DATABRIDGE_OLEDB', @optname=N'rpc', @optvalue=N'false'

GO

EXEC master.dbo.sp_serveroption @server=N'DATABRIDGE_OLEDB', @optname=N'rpc out', @optvalue=N'false'

GO

EXEC master.dbo.sp_serveroption @server=N'DATABRIDGE_OLEDB', @optname=N'sub', @optvalue=N'false'

GO

EXEC master.dbo.sp_serveroption @server=N'DATABRIDGE_OLEDB', @optname=N'connect timeout', @optvalue=N'0'

GO

EXEC master.dbo.sp_serveroption @server=N'DATABRIDGE_OLEDB', @optname=N'collation name', @optvalue=null

GO

EXEC master.dbo.sp_serveroption @server=N'DATABRIDGE_OLEDB', @optname=N'lazy schema validation', @optvalue=N'false'

GO

EXEC master.dbo.sp_serveroption @server=N'DATABRIDGE_OLEDB', @optname=N'query timeout', @optvalue=N'0'

GO

EXEC master.dbo.sp_serveroption @server=N'DATABRIDGE_OLEDB', @optname=N'use remote collation', @optvalue=N'false'

Many Thanks

How can I access the data stored in a Linked server?

Any help would be appreciated.

@srvproduct=N'',
@provider=N'MySQLProv',
@datasrc=N'203.xx.xx.xx',
@catalog = N'Store'

exec sp_addlinkedsrvlogin 'OLEDB_test','false',null,'root',''

select * from OLEDB_test.Store.root.Books
