Posted this at the tail end of another thread but that one appears to have died. Thought I'd try again since my question was a little distinct from that one anyway, but apologies if I've committed forum sacrilege.
I am having a heck of a time trying to migrate a fairly simple MySQL DB to SQL Server I am using SQL Server 2005 Standard Edition SP1.
I tried following MS' instructions in this article:
hoping that what worked for 2000 would work for 2005, since the principles seem sound. No luck. I can create the ODBC link, but SQL Management Studio, the '.NET provider for ODBC' option doesn't give me the choice to copy tables - only to write a query.
I tried making sense of the on-line help and was able to create the ODBC connection in the 'Business Intelligence Development Studio' but I have no idea what I am looking at with respect to creating control & data flow in an SSIS package. All I know is that I could do what I am trying to do in SQL Server 2000 quite easily - the MySQL database in question is quite simple (but not small). I am pretty amateurish when it comes to SQL administration, but this seems to me unnecessarily difficult.
I tried the MySQL OLE connector from sourceforge and was able to properly set up a test connection and get the 'copy tables' option, but then when I hit 'next' I get:
MYSqlProv 3.9 failed with no error message available, result code E_ABORT(0x80004004) (System.Data)
Am I missing some stupendously easy way around this, or did I torpedo this client when I promoted moving them from MySQL to MS SQL Server on account of my not being a full-time SQL Server DBA who knows how to use the Business Intelligence Development Studio?

This test creates two threads each with a database connection and uses transactions to insert values into the same table. The objective of this test is to check that a thread cannot read the results from a pending transaction on a different thread. In effect this checks dirty reads do not happen and transaction locking.
The test runs correctly and displays "PASSED" with MySQL indicating the transaction and threading worked. When running with MSSQL Express 2005 it reports a deadlock error during a transaction. It's not really possible to re-run the transaction and I would like MS SQL to operate similar to MySQL, i.e. MySQL waits for the other transaction to finish before the next transaction can operate on those table rows. I'd like to use MSSQL but I am wondering why this error doesn't happen with MySQL and so have, for the moment, chosen to use it as my preferred database solution. I have experimented with transaction isolation levels and this doesn't seem to solve the problem.
I've tested this with a fresh install of Windows XP SP2 and no firewall turned on.
To run this test with MSSQL Express2005 use the ODBC Data Source Administrator (odbcad32.exe) to create a data source named MyExpressTest and attach this to an empty database that has been created with the default values. Enable the #define MSSQL in the coude otherwise it tests with MySQL.
To run this test with MySQL (to show how this test should work) use the ODBC Data Source Administrator (odbcad32.exe) to create a data source named mySQLNewTest and attach this to an empty database that has been created with the default values. Comment out the #define MSSQL to switch to MySQL mode.
Hi, we are writting a SQL Server Integration Services package to import data from a MySql database to a Sql Database.
We are using ODBC 3.51 Drivers to connect to the MySql Database in SSIS. The package runs perfectly in design mode. When we schedule the package to run, the package seems to hang about 1/3 of the times.
What can this be. We used to the package and ran it from a Sql Server 2005 to a Sql Server 2005 database. This setup works perfectly. When i'm doing MySql to Sql Server 2005, 1/3 of the times, it does not work.
I am testing an application that uses mysql that works 100% fine with Microsoft Windows XP on Windows Vista Premium Home Edition.
Using Vista's ODBC Data Source Administrator I have set up and successfuly tested the DSN Connection to the Database.
However, when I call the set up DSN with the application I get [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified.
I am using the mysql-connector-odbc-3.51.12-win32.
I have tried editing the registry DSN files - the problem still persists.
Two connections ==> one is using OLEDB connecting to SQL server 2005 and the other using ADO.NET's ODBC option to connect to mysql;
Two "Execute SQL Task" ==> one gets maximum ID(bigint) from a SQL server table and the other gets the maximum ID(unsigned) from a mysql's table and bind them to two variables ID1(string) and ID2 (int 64). http://forums.microsoft.com/TechNet/ShowPost.aspx?PostID=1902297&SiteID=17&mode=1 ;
And one DataFlow whose data source is DataReader Source which queries mysql "select * from table where ID > cast(@ID1 as signed) and ID <= cast(@ID2 as signed) ". To debug, I put a DataViewer between Data Flow Source and Data Flow Destination.
Run the package, I found no data coming into DataViewer and no error message as well. However if I remove the "<=" sign and change the DataReader Source query to "select * from table where ID > cast(@ID1 as signed)", It works perfectly. Initially I thought it's variable @ID2's issue. But if I replace "<=" sign with ">=" sign in the query ==> "select * from table where ID >= (cast(@ID2 as signed) -100)", there is no problem. After tried many times, I found that query just doesn't work with "<" sign or "between". Plus the result of running package tells it's successful but just no records got inserted into Data Flow Destination.
I have a SQL Server 2005 and am trying to create an OPENDATASOURCE with MYSQL. I downloaded the MYSQL 3.51 driver and installed it on the SQL Server, but am unable to connect. I keep getting the OLE DB provider "MySQLProv" has not been registered.
Any help would be greatly appreciated. Thanks Susan
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

I've been asked to migrate a db in MySQL to SQL Server 2005. Since I'm only familiar with sql server 2000 and before, I dont' know where to begin looking for the information I need. Can someone point me to what I would search for in SQL Server 05 for this (is there any new features here I should be aware of that might make this easier?) If anyone has done this, what are the gotcha's or things I should be aware of. Thanks for any input
I have sql 2005 server in my local area and mysql server on internet..
How can replicate Ms SQL 2005 to MYSQL ? is that possible ? or any possible version this server ?
I try sql 2000 server for replication; publishing starting but then ı take "invalid cursor state " message. ı delete tables msrep7 in mysql then replication starts but if replication stop for any reason , ı must delete table again again...
Can both be run on the same service I have a asp.net application that need to use the MS sql 2005 and I have another application PHP that requires MySql. Can bot be run ont hte same server at the same time???
Hello. I have the following problem. I have a database in mysql and i want to migrate in ms sql server 2005. How can i do that? I have downloaded and installed MySQL Connector/ODBC .
im trying to develop a web application that uses a backend database, however im not quite sure what db backend to use. What are the diffrence between sql server express and mysql.. which is better to use in terms of small enterprises.? what are their limits..?
I'm trying to use linked server to import big amount of data(around 9 million rows) from mysql to a sql 2005 table.
I plan to create a stored procedure and use job agent to run it at off-peak time everyday. The SP is like:
.....
Truncate table sqltblA;
Insert Into sqltblA(col1, col2, col3) Select col1, col2, col3 From OpenQuery('mysql', 'Select col1, col2, col3 From mytblB')
.....
But when I tried to CREATE the above SP from management studio, seems the sql server was trying to get all data from table mytblB and ended up with failure after several minutes hang. The error message is sth. like "running out memeory". BTW, during that several minutes hang, I can't query mytblB using mysql's tool as well. it seems to me that table got locked.
However if i try to change the returned result to 100,000 rows by changing script to
Insert Into sqltblA(col1, col2, col3) Select col1, col2, col3 From OpenQuery('mysql', 'Select col1, col2, col3 From mytblB Limit 100000')
The SP could be created without any problem and running the SP could get the data in table sqltblA.
But that's not what I want, I need all rows instead of a certain amount of rows.
Does anyone know what's going on there when I try to CREATE that SP and any solution to it?
Plus I tried to use SSIS as well. When I'm configuring the DataReader source, which uses ADO.NET's ODBC option to connect to mysql, if its sqlcommand is "select * from mytblB" without the Limit key word, then the configuration page will hang there as well and table mytblB is not accessible by using mysql tool. I'm just sick of wasting time on that and that's why I chose to use SP istead of SSIS. But same result. :-(
Please help me, i am having trouble in Adding data in MySQL Database, and even in Getting or retrieving Data as well.
I use the connection string of Visual Basic 6.0 (ODBC 3.51). Nothing goes wrong with the connection but in updating and adding new data in the MySQL Database then...that's it, nothings go Right!
Please help me in this matter, or can somebody to please give me some simple codes like Address Book using the Visual Basic 2005...
I am trying to migrate from MySQL 4.1 to MS SQL Express 2005 1. do i need to create an empty db under Express 2. can this be done from within Express by pulling from MySQL into Express or do I need to work from command lines 3. what would be the cleanest way to approach this
I have a MySQL dump and did look at the result from within Express, but it was not an import, I would like to find a way to import if possible that data. Table by table would be fine.
Can anyone recommend me how I can convert MySQL database to MS SQL server 2005 database? I am new to the SQL server 2005. Is there any ODBC I can use? Thanks in advance
Please help - I am dealing with data transfer from multiple tables to multiple tables - what is the best practice to get this done? So far I have my connection to MySql figured out and I am using a DataReader source to get the data. What is the approriate Data Flow Transformation to pump data into three different tables in MS Sql 2005 database from three different tables in MySlq database? So far I was able to figure out how to do this for one table only...
I'm trying to upsize an Access database to SQL 2005 Express. When I follow the wizard and I've tried all ways of connecting to the database I get the following error
Connection failed SQL State '01000' SQL Server Error 53 [Microsoft] [ODBC SQL Server Driver][DBNETLIB] ConnectionOpen()). Connection failed SQL State '08001' SQL Server Error 17 [Microsoft] [ODBC SQL Server Driver][DBNETLIB] SQL Server does not exist or access denied
I've tried using local host and typing the exact server connection string from the SQL Express Management tool and nothing is working
How come I can't do this? Everyone says this is easy and straight forward -- not for me.
so as you can see i want to migrate from My SQL 5.0 to MS SQL Express. Is there any free tool provided by microsoft or something else i could to use to migrate my databases. I need this cause old web page was developed on PHP and now it's redeveloped on ASP.NET and i have very strange issues with ASP.NET and MySQL Lots of incompatibility and performace degradation, so i would like to try out MS SQL i think it must be better.
Hi all,I am developing a web application and the back end is MySQL database. Now I want to shift all the data to SQL Server 2005. Is there any method to do it? Thanks Tomy
Hello, Finally making the move to ASP.NET! I've been advised that to begin with it is probably best to start using SQL Server 2005 with ASP.NET. All my sites are currently using MySQL. Can anyone advise a way for me to import all the data from a MySQL database to a SQL Server 2005 database. Apologies if this isn't directly related to ASP.NET but any help would be greatly appreciated. Thanks
hey all, i want to know Equivalent of "LIMIT" of MySQL in SQL Server 2005? in mysql we can direclty get data using LIMIT clause. my question is how to do this in sql server 2005? thanks.
Does anyone know of a reference site where I can find a reference table to get a better idea of data type conversions that I should be using?
I have a MySQL 5.0 database which had a lot of tables (mostly empty) that I already have gotten transferred to SQL Server 2005. However, I am suspicious of some of the data type conversions that SQL Server did.
I would really like a good web site to bookmark to help me with this if there is such a reference. Can anyone help?
If not, the most specific example I have right now is a MySQL column that is expecting to accept currency and the MySQL data type is "Double". SQL Server 2005 translated this as a "float" data type. I normally use a "decimal" data type.
i've got a database stored on my computer using mysql server 2005, and I've just registered for hosting which uses the Plesk control panel. In plesk I've setup a database and relevant user. What the easiest way of exporting the whole database on my computer and getting it onto my hosting account?
I 'm trying to get countNumber from a select statement in MySQL source. Something likes this:
select @countNumber = count(*) from tableName where condition_1 = xxx
I use ExecuteSQLTask to get the result set with result name @countNumber along with ADO.NET connection type. I 've installed mysql-connector-net-5.0.5 cause the source is MySQL 5x.
And I got a task failed error which is described below:
[Execute SQL Task] Error: An error occurred while assigning a value to variable "new_process": "Result binding by name "@new_process" is not supported for this connection type. ".
Problem: Moving data from mysql to sql server 2005
I am trying to pull data over from mysql to sql server. First the import wizard greys out so I have to put in 1 query at a time which is pain. and second it does not even work! it takes me through the end of the wizard for me to click finish and then says oops it does not work. there was an error!
Anyway i tried going through the ssis route cuz its going to be a nightly job. i used the ado.net odbc connection. It worked but the performance is really not acceptable. it took 5 mins to import 24000 rows where as dts was taking 1 sec to do this. i wish i could use the native mysql odbc 3.51 connector and import. can some one give me step by step instructions on how to do that ?
I hear someone mentioned of using excute sql task which can use mysql odbc 3.51 driver. but since i am new how do i get it to work. say for example in the excute sql task i run a statement like select * from addr. then what?
cuz eventually i want the result to be saved in a sql server table called addr. How can i get the result from that excute sql task and put it inside of an addr table in sql server. should i save the result to a variable of type object. but then how do i get the data from object and tell sql server in the designer that the result contains these columns and it needs to map to these columns in the addr table of sql server.
Very confused. i wish the first option would have given me results which an enterprise ETL gives. but apparently it is too slow that it wont be acceptable in a production envrioment. when i will have millions of rows coming in .
