Mysql linked server queries

Question

hello everyone, after spending most of the day trying to figure this out i hope that you guys with more experience can provide some suggestions. i have been experimenting with the a linked server (MYSQL 5) and managed to get all the select queries to work
fine, but the insert is giving me troubles. MSSQL is 2008 R2, the odbc connector is the most recent.
so here is some useful testing material:
-- Table structure for myTest on the MYSQL server
DROP TABLE IF EXISTS `myTest`;
CREATE TABLE `myTest` (
`id` bigint(20) NOT NULL,
`mystring` varchar(50) COLLATE utf8_unicode_ci DEFAULT NULL,
`mydate` datetime DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;
-- Records
INSERT INTO `myTest` VALUES ('1', 'string1', '2009-04-17 13:11:41');
INSERT INTO `myTest` VALUES ('2', 'strin2', '2009-04-17 13:12:48');
INSERT INTO `myTest` VALUES ('3', 'string3', '2009-12-09 12:29:48');
INSERT INTO `myTest` VALUES ('4', 'nostring', '2009-12-18 12:29:48');
INSERT INTO `myTest` VALUES ('5', 'stfing5', '2010-07-17 16:40:00');
then i copied the data from mysql to MSSQL and made up new data and copied it into the 'local' copy of the mysql table:
-- copy stuff from mysql
select *
into [msTest]
from openquery(MYSQL, 'select * from myTest');
--make a copy and change a row for this example
select * into [msTestCopy]
from [msTest];
UPDATE [msTestCopy]
SET [id] = 10
,[mystring] = 'sadfasdfas'
,[mydate] = '2009-04-17 14:11:41.0000000'
where [ID] =1;
-- insert new row in the imported table
declare @myId as int;
set @myId=10;
insert into [msTest] ([ID],[mystring],[mydate])
select T1.[ID],
T1.[mystring],
T1.[mydate]
from [msTestCopy] T1
where T1.[ID] = @myId;
Then i tried an update query which was successful:
UPDATE OPENQUERY (MYSQL, 'SELECT mystring FROM mydatabase.myTest WHERE id = 1')
SET mystring = 'sadfasdfas';
Now this is where things just do not work. i tried an insert with the following:
-- insert in mysql
insert OPENQUERY(MYSQL, 'SELECT * FROM myTest')
select * FROM [dbo].[msTest] T1
where T1.[ID] = @myId;
the error returned is not very useful"
Msg 7399, Level 16, State 1, Line 5
The OLE DB provider "MSDASQL" for linked server "MYSQL" reported an error. The provider did not give any information about the error.
Msg 7343, Level 16, State 2, Line 5
The OLE DB provider "MSDASQL" for linked server "MYSQL" could not INSERT INTO table "[MSDASQL]". Unknown provider error.
then i went back to basics and tried the following
insert OPENQUERY(MYSQL, 'SELECT * FROM myTest')
values (7,'sadfasdfas','2009-04-17 14:11:41.0000000')
 similar error as a result:
Msg 7399, Level 16, State 1, Line 1
The OLE DB provider "MSDASQL" for linked server "MYSQL" reported an error. The provider did not give any information about the error.
Msg 7343, Level 16, State 2, Line 1
The OLE DB provider "MSDASQL" for linked server "MYSQL" could not INSERT INTO table "[MSDASQL]". Unknown provider error.
Does anyone have any clue of what is happening and how i could solve it?

Answer 1

If I use the above syntax:
EXEC master.dbo.sp_addlinkedserver @server='MYSQL', @srvproduct='NAME OF MYSQL ODBC',
@provider='MSDASQL', @provstr='DRIVER={MySQL ODBC 5.1
Driver};SERVER=SERVER IP;Port=3306;USER=myUid;PASSWORD=myPassword;OPTION=3;DATABASE=photo;'
the linked server creates properly, but it won't even let me run this statement anymore:
select * FROM OPENQUERY(MYSQL, 'SELECT * FROM photo.tag_type');
It give this error:
/* OLE DB provider "MSDASQL" for linked server "MYSQL" returned message "[Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified".
Msg 7303, Level 16, State 1, Line 1
Cannot initialize the data source object of OLE DB provider "MSDASQL" for linked server "MYSQL".  */
If I add this to the create statement @datasrc='MYSQL_MAIN' -- this being the name of the MySQL ODBC, therefore looking like this:
EXEC master.dbo.sp_addlinkedserver @server='MYSQL', @srvproduct='MYSQL_MAIN',
@provider='MSDASQL',@datasrc='MYSQL_MAIN', @provstr='DRIVER={MySQL ODBC 5.1
Driver};SERVER=SERVER_IP_ADDRESS;Port=3306;USER=myUID;PASSWORD=#####;OPTION=3;DATABASE=photo;'
I can at least run the above select statement, but I still get the error when running the insert statement.
Insert statement:
INSERT OPENQUERY(MY_SQL, 'SELECT * FROM photo.tag_type') VALUES (1, 'test');
Error:
/* OLE DB provider "MSDASQL" for linked server "MY_SQL" returned message "[MySQL][ODBC 5.1 Driver][mysqld-5.0.48-log]Commands out of sync; you can't run this command now".
Msg 7343, Level 16, State 2, Line 1
The OLE DB provider "MSDASQL" for linked server "MY_SQL" could not INSERT INTO table "[MSDASQL]".  */
So can you please specify your exact syntax for this create linked server query and maybe a sample insert?  Which version of MySQL are you running?  I have tried a lot of different things and even read this post, http://bugs.mysql.com/bug.php?id=39965 with
no luck, please help.
Thanks
