I've been put in charge of migrating a customer's website of MS SQL/ASP to PHP/MYSQL. I have zero experience with MS SQL.
I'm trying to figure out the best way to get the current data migrated to MySQL so I can begin PHP development.
Some details:
I downloaded SQL Server Mangement Studio Express. I found the following string in a connection file:
MM_connCompanyName_STRING = "provider=SQLOLEDB;data source=IP_ADDRESS;database=DATABASENAME;uid=USERNAMEpwd=PASSWORD;"
Using the IP, username, and password from this string, I could successfully connect using Studio Express.
I downloaded the MySQL Migration Toolkit and entered the same info, but get the following error:
Connecting to source database and retrieve schemata names.
Initializing JDBC driver ...
Driver class MS SQL JDBC Driver
Opening connection ...
Connection jdbc:jtds:sqlserver://IP_ADDRESS:1433/DATABASENAME;user=USERNAME;password=PASSWORD;";charset=utf-8;domain=
The list of schema names could not be retrieved (error: 0).
ReverseEngineeringMssql.getSchemata :Login failed for user 'USERNAME'.
I don't have admin or physical access to the current SQL server. I've tried to run some exports through Studio Express, but it saves them to the file system, which I don't have access to.
I can reach the current/old webmaster, but because he no longer works for the company, his responses are slow and usually un-helpful. So no help there...
The former admin sent me an MDF file ... no idea what to do with that.
I found this note above the connection info on the current server (if it means anything):
'this connection is being used because
ODBC was causing weird errors,
switching to OLEDB fixed them
My questions:
Any idea why this would be failing with the same login credentials that works with Studio Express? I'm assuming it has something to do with the driver, but I don't know what next steps to take.
Is there a better/easier/more effective way to migrate this data? (I'm hoping I don't find myself running "SELECT *" statements in Studio Express and copy/pasting data into Excel...please god, no)
Thanks in advance for your help.
Eww, this is going to be scary (connection string indicates it was tool generated from Dreamweaver, never a good sign).
Any idea which version of SQL Server? You should be able to SELECT ##VERSION. 10.x is 2008, 9.x is 2005 and 8.x is 2000. If it is 7.x run.
The MDF file is the actual database. If I were you, I would buy a developer edition of SQL 2005 (or 8 if it is 2008 which is unlikely), it will be worth the $99 or so it costs.
This will give you the ability to locally install the DB by ATTACHing the MDF file. Once you have a locally running copy, you can use the SQL Server ETL tools with the MySql ODBC drivers to push the data to MySql in a repeatable manner.
I believe you can export data from MSSQL choosing different SQL dialects; I believe there's one that's reasonably MySQL compatible. It doesn't solve all your problems, of course, because while you may get the structure properly, stored procedures and triggers and the like will take a bit more work. But that should get you started.

I just installed SQL Server 2012 to test differences and make sure it is ok for my Work. I may not be a pro at SQL, but I don't see how to add a Link to Jet database on my server. I have imported Jet Databases, but when going thru the GUI to Link a JET Database I see no Provider for JET. I am running Access 2003 (I don't like the 2008+ GUI)
I searched an found nothing simular to my issue; at least nothing I understood. Nothing mentioned how to add Jet db Provider.
I ran a connection string to the Jet Database thru QA:
sp_addlinkedserver 'USGEScrub', 'Access', 'Microsoft.Jet.OLEDB.4.0',
'D:\Lead$\SupList\USGEScrub.mdb'
The connection string works till I try to access the data and then I get this the errorand of course if I click the links nothing shows up:
TITLE: Microsoft SQL Server Management Studio
Failed to retrieve data for this request. (Microsoft.SqlServer.Management.Sdk.Sfc)
For help, click: http://go.microsoft.com/fwlink?ProdName=Microsoft%20SQL%20Server&LinkId=20476

I had a similar problem and in my case it turned out to be related to the permissions on the %TEMP% folder for the account under which the SQL Server service was running. For more details see my answer here.
Sometimes this problems occurs in computers x64 with office x84 versions installed. Try this:
Install pasive OleDb Driver x64
Are there any free solutions for automatically migrating a database from MySQL to SQL Server Server that "just works"?
I've been attempting this simple (at least I thought so) task all day now. I've tried:
SQL Server Management Studio's Import Data feature
Create an empty database
Tasks -> Import Data...
.NET Framework Data Provider for Odbc
Valid DSN (verified it connects)
Copy data from one or more tables or views
Check 1 VERY simple table
Click Preview
Get Error:
The preview data could not be
retrieved. ADDITIONAL INFORMATION:
ERROR [42000] [MySQL][ODBC 5.1
Driver][mysqld-5.1.45-community]You
have an error in your SQL syntax;
check the manual that corresponds to
your MySQL server version for the
right syntax to use near
'"table_name"' at line 1 (myodbc5.dll)
A similar error occurs if I go through the rest of the wizard and perform the operation. The failed step is "Setting Source Connection" the error refers to retrieving column information and then lists the above error. It can retrieve column information just fine when I modify column mappings so I really don't know what the issue is.
I've also tried getting various MySql tools to output ddl statements that SQL Server understand but haven't succeeded.
I've tried with MySQL v5.1.11 to SQL Server 2005 and with MySQL v5.1.45 to SQL Server 2008 (with ODBC drivers 3.51.27.00 and 5.01.06.00 respectively)
There are two free toolkits provided by Microsoft.
Microsoft SQL Server Migration Assistant for MySQL v1.0
http://www.microsoft.com/download/en/details.aspx?displaylang=en&id=14280
Microsoft SQL Server Migration Assistant for MySQL v5.1
http://www.microsoft.com/download/en/details.aspx?id=26712
I have used only the second one and it worked for me without any glitch.
It required registration with Microsoft for downloading a license file.
But it is free to use for everyone.
This is really old now, but if you use MySQL Connector NET and set SQL Server Mode = true in the connection string, this will resolve your error.
Recently, I have successfully migrated the MySQL database to MSSQL database. Below are detailed steps:
Operating System: AWS Microsoft Windows Server 2012 R2 with SQL Server Standard
Tools Used:
SQL Server 2014 Management Studio SQL Developer,
Microsoft SQL Server Migration Assistant v6.0.1 for MySQL,
Remote Desktop Client, and
Third Party MySql ODBC Driver 5.1.13
1. Setup AWS Windows Server
2. From the AWS console ec2 instance list, right click on the windows server and select connect. You would see the similar screen below.
3. Click on the Get Password button which will be required for Remote Desktop connection[#4] and follow the instructions.
4. Connect to that EC2[#1] instance with the Remote Desktop Client by default available in your Ubuntu local machine. Use the credentials from #2.
5. Once you get connected using the remote client, you should be able to access the remote MSSQL server. Install the following tools.
Install Chrome : Since internet explorer has some security, install chrome.
Install Microsoft SQL Server Migration Assistant v6.0.1 for MySQL
https://www.microsoft.com/en-us/download/details.aspx?id=51218

Connect to MSSql
Convert Schema
Migrate Data
8. You might have some problem listed here. Please read in detail where I have written the detail resolution.
MySql 5.6 to MSSql server 2014 migration : ExecuteReader requires an open and available Connection
I am afraid there is no simple solution. SQL used in MySQL and T-SQL used in SQL Server 200X are different dialects of SQL. It is not only simple changing say "auto_increment" to "identity", but reserved words that creates a problem.
For example
CREATE TABLE test (
user varchar(50)
)
will work in MySQL and fail in SQL Server 2008.
To cut long story short - unfortunately, you will need to do it by hand.
Export the file from MySQL to a CSV file.
Export the create statements for the tables from MySQL
Cry.
3a. Disable foreign key checks in SQL server
Tune the create statements in SQLserver until they work.
Import the CSV files in to MySQL.
5a. Enable foreign key checks in SQL server.

Had similiar issue about this error 42000, and for me I figured out that setting the MySQL global mode to ansi_quotes would solve it:
set global sql_mode=ansi_quotes;
There are commercial solutions, but not free solutions. Depending on complexity of your database, rewriting SQL for target dialect can be trivial task - or a very hard one.
Rewriting CREATE TABLE statements is never hard, it can be done by hand with no surprises. Procedures, functions and triggers are problematic.
I am working with SSIS and trying to import data from MySql to SQL Server. I am having issues trying to convert mySql datetimes to SQL Server Datetimes. Any suggestions?
Can you provide an example of the error or problem? I found some values in MySQL were out of range to SQL Server. In these instances, I used a NULLIF on the MySQL side to remove the bad values first. Rafal Ziolkowski's solution of converting to strings could work as well, but I personally would prefer to push the conversion off to the MySQL query if it is only impacting data columns.
Try convert date to string and then to datetime again.
What is the issue? Which SSIS data type are you using? DT-DBTIMESTAMP should work for both.
this took me few days to figure out...so I thought I would share my notes
How to connect and load data from MySQL to SQL Server
Download the 32 bit ODBC driver.
go to the MySQL website and download: “mysql-connector-odbc-5.2.4-ansi-win32.msi”
NOTE: Do not use the 64 bit driver on BIDS 2008. BIDS 2008 is 32 bit. You will get a mismatch error when creating SSIS’s connection manager: “The specified DSN contains an architecture mismatch between the Driver and Application”
Create a User DSN
You need to open the using windows 32 ODBC admin tool. DO NOT open the regular ODBC admin, in control panel. Open the ODBC admin located here: c:\Windows\SysWOW64\odbcad32.exe. If you use the default ODBC admin…it will not work. Additionally you must create a “User DSN” - NOT a System DSN. Otherwise it will not show up in SSIS
NOTE: the screens look the same so you will have no way of knowing whether you are in 32 BIT ODBC Admin tool or not.
Create a new SSIS package and create an ADO.NET connection manager:
Change the Source ADO.NET properties.
You will get validation errors and your package will not run. You need to change the “ValidateExternalMetadata” to FALSE (in the “Advanced Editor” dialog box) of the ADO.NET source It will also give you metadata error…that’s ok…just click ok. It will still pull the metadata (column names/data types). You cannot select the tables as you would in SQL server. You need to type the SQL select statement.
Run the package and should run and load normally.
Is there any way to connect SQL Server 2008 Reporting Services to a Sybase SQL Anywhere database (ASA or ASE)? Maybe using ODBC...
If so, have you done it? Kindly share experiences and any notable considerations.
Our environment is x64 SQL RS but needs to connect x86 SQL Anywhere 9.0. 64bit SQL doesn't recognize 32bit ODBC SQL Anywhere. We resolved the issue by installing a x86 SQL Server 2008 R2 express, setup a System ODBC for SQL anywhere and linked server to SQL Anywhere on SQL instance.
Check "Allow inprocess" in the the linked servers->Provider->ASAProv.90. Restart SQL Service
Linked server -> Server Options: Set RPC and RPC Out both to True.
I have had success setting up the Data Source Type (DPE) as OLEDB and using the ASA 9.0 OLEDB provider. The connection string editor in VS2008 does not allow me to create a connection string that works, so I just type in the entire connection string as follows:
Provider=ASAProv;Eng=[ASAInstanceName];Dbn=[ASADatabase];Uid=[ASAUser];Pwd=[ASAPwd];Links=tcpip(host=[servername])
Replace the the portions with square brackets with the values that are appropriate for your installation. The square brackets should NOT be in your final connection string and quotes are not need either. The links statement at the end is probabaly not necessary if the database is on your local machine. Even though I included the database username and password, it didn't seem to be used. I also had to set them in the DataSource Credentials. When deployed to SSRS, I also set them in the DataSource to be saved on the server.
I've noticed that performance is VERY slow when previewing the report in local mode in VS 2008. Instead, I have started deploying my report everytime I want to "preview" it so I can look at it on the SSRS server through a browser. Performance is much better that way.
I am looking for a BETTER solution than what I've described as I've quickly found that multiple-value parameters are not supported with this type of connection to ASA. If you find a better solution, perhaps using the ASA ADO.NET Provider, please post. From what I've found though, there is no DPE that exists for ASA.
I am moving from SQL 2000 to SQL 2008. The SQL 2000 is on a Server 2003. SQL 2008 is on a Server 2008. I have imported my database successfully. I am able to perform queries and they work fine. I use a VB6 program running in the IDE to update the database.
When my VB6 program runs on a server 2003 the program will connect using the following connection string:
Provider=SQLOLEDB;DATABASE=mydbname;SERVER=my ip;DRIVER={SQL SERVER};UID=myuser;PWD=mypw;
Using the above connection string, I can connect with no errors to either SQL 2000 or the new SQL 2008 database. On the Server 2008, there is no SQLOLEDB driver show, so I have to use the new SQLNCLI10 provider
CCTdbConnectionString = "Provider=SQLNCLI10;Server=myServer\My InstanceName;Database=MyDB;UID=myuser;PWD=mypw;
Here's the problem. When I am running on the Server 2008 I get the error 3228 Selected collating sequence not supported by the operating system. If I hit debug and try again, or stop the program and try again it gets past that error until I reopen the IDE. Then I get a 2nd error encountered is an error 3027 Can Not Update. Database or object is read-only! This never goes away and I'm dead.
After Much research, I have found the answer. SQL 2005 and up apparently require a Unique Key Index exist on every single table that is accessed using ODBC or OLEDB.
This Cures the problem.
Compile the code: don't use the IDE?
