Convert a .bak file to .sql file - mysql

I have a asp script that I'm intending to write it with PHP so I have to get its database and use it.
I have the database as .bak file which I understood that it's a backup and I wanna change it to be .sql to import it in phpMyAdmin
I read about this matter in the web but I didn't find an accurate tutorial that goes through the whole process.
They are talking about mssql database but I didn't even reach this step..
Any help will be highly appreciated. Thanks in advance :)

Note, all of this applies to MS SQL because .bak is a usually a MS SQL backup.
A .bak can't be converted to SQL directly -- it contains a backup of a database which does not have a clear relationship to SQL.
You could restore the backup and then use SQL Server tools and then use that to make some SQL to recreate the SQL server objects but not the dat.
From SQL Server Management Studio: Datbases item, right click "Restore
Database" then from datbase right click script database.
This won't script the data.
The other option is to use RedGate's excellent tools, which should do everything you want.

Most probably the .bak file is indeed a binary backup of a Microsoft SQL Server database (which is something completely different than MySQL).
So you will first need to install Microsoft SQL Server (Express) together with the SQL Server Management studio (I think there is a bundled download "SQL Server Express including Tools".
In the Management Studio you can then import the .bak file into a new database. Once the import is finished you can use it to create SQL script out of the database.

Importing .bak from MSSQL into MySQL database

My companies site uses a mysql database. One of our clients just trying to take advantage of our API is only able to give us the data in the form of a MSSQL .bak file
I have been trying to import the file using the migration tool built inot mysql workbench but have no luck.
On top of that I am trying to see if this can be done in powershell as I would like to automate this process in the future.
Any suggestions or help would be appreciated
You cannot. MS SQL Server backups are proprietary to MS SQL Server and cannot be used with any other RDBMS. You will need to restore this backup to SQL Server, then use an additional tool to transfer the data from SQL Server into MySQL.
Can you do that second portion through PowerShell? Probably. Though SSIS would probably be a better method.

Create MySQL database from .mdf and .ldf files from SQL Server 2008

I have some .mdf and .ldf files of database size greater than 10 GB with me.
I want to create a MySQL database using the same.
Is there any provision in MySQL to do it?
Please consider that MySQL and SQL Server 2008 can not be installed on the same machine (or even the same network) in my current setup.
I don't have enterprise edition of SQL Server management studio in our network and will not be able to install it.
Is there any other elegant way to export data from SQL Server 2008 and import it in MySQL?
I don't think it is possible without attaching.
If you find a way how to attach it, you can use some specific migrating tools like this.
Some tools allow to create database specific queries from another solution, that need to be only executed on your side.
The MDF and LDF files belong to Microsoft SQL Server and use Microsoft's own binary format, so you cannot connect these files to other database management systems. The only approach I can think of, is to script out the database code and data from the SQL Server database to a text file (.sql file), and import this file into MySQL.

Can we restore database backup of SQL Server 2008 R2 Express to SQL Server 2008 Express

I have a database backup in "SQL Server 2008 R2", Can i store this database backup in "SQL 2008 Express" ?
Anyone who have knowledge about SQL-2008 kindly share to me.
No and 'yes'.
A backup (.bak) is not possible, nor is copying .mdf over but you can downgrade.
You could go back to 2005 if you wish to.
I found this information which runs you through it the easy way.
How to Downgrade SQL Server Database
Direct link: http://www.mytechmantra.com/LearnSQLServer/Downgrade_SQL_Server_Database_P1.html
TIP: Use Microsoft OLEDB connector to destination instead of the native client and you should avoid any errors in the transfer
Nothing is impossible, you just have to get creative :)
Install an instance of SQL 2008 R2 on one machine and SQL 2008 on another
Open SQL Server Management Studio R2
Select your source Database
Select Tasks>Generate Scripts.
Select 'Script entire database and all database objects', press 'Next'
Select 'Save to File' and click on the 'Advanced' button
Select 'Script for Server Version' and select the version you want: 200/2005/2008
Select 'Type of data to Script' and select Schema/Data/both
Click 'OK',Next and do it!
Copy the resulting file to the target machine with SQL 2008 [or whatever]
Log onto your SQL Management Studio and open the copied .sql file... be aware that there may be limitations on the file size.
There may also be issues with the order that the .SQL file inserts the data into the target database and if there are FK constraints in place, this could be an issue.... simply re-order the insert lists.
Once the .sql file is organized, parse it [just to sure], and then execute.
Let me clarify a little on these directions.
On the SQL Management Tools be logged into both the old and the new server if possible.This makes these steps even easier.
So, start with the source server, right click on the database and script it. There is one option called ‘Script Data’ that is off by default, we set it to true so the script will include inserts for all of the data. We choose to script the tables, views, indexes and keys (and triggers … not sure if you use any of those). I also did not mess with the users, since that is problematic. It is easier to create the user by hand once on the local SQL server and give them permissions to the dbs.
Then script the DB to a file.
Then select the local SQL server and add the database by hand, then open up the script file and execute it under the new database, all the tables, data, indexes, etc came over just fine. Setup the user permission and you are golden.
NO, you cannot do this.
There is no way, no method, no hack, no workaround, no trick to get a backup from a more recent version of SQL Server back into an older version.
It just doesn't work - it's not supported.
You'll need to synchronize your structure using some kind of SQL diff tool, and possibly your data by exporting and importing, e.g. via the "Data Export / Import" wizard or some custom way.

Convert MSSQL2008 *.bak file to SQL-CE *.sdf

I wish to convert data from an mssql2008 .bak (or out from a running 2008 server) to sql-ce's *.sdf for use in a webmatrix project. I have SQL Server Management Studio 2008 R2 installed as well.
There is no tool that will directly convert a bak to an sdf.
You're going to have to restore it to a functional SQL Server Engine of the same (or newer) version and then script it out. That's how I'd do it anyway. Also keep in mind that you're not going to be able to use the views, stored procs, triggers, etc, if there are any in the database contained in the .bak file.
There was a codeproject effort with SQL 2005 to create a utility that would help with the conversion from a full blown database to a ce database. You can check it out here:
http://www.codeproject.com/KB/database/SqlCompactCoptUtility.aspx
For help with scripting start here:
http://msdn.microsoft.com/en-us/library/ms178078.aspx
Or to just dive right in: Right-click a database, point to Tasks, and then click Generate Scripts. That will bring up a wizard with all sorts of options to help you get the tables and data moved.

How to import a SQL Server .bak file into MySQL?

The title is self explanatory. Is there a way of directly doing such kind of importing?
The .BAK files from SQL server are in Microsoft Tape Format (MTF) ref: http://www.fpns.net/willy/msbackup.htm
The bak file will probably contain the LDF and MDF files that SQL server uses to store the database.
You will need to use SQL server to extract these. SQL Server Express is free and will do the job.
So, install SQL Server Express edition, and open the SQL Server Powershell. There execute sqlcmd -S <COMPUTERNAME>\SQLExpress (whilst logged in as administrator)
then issue the following command.
restore filelistonly from disk='c:\temp\mydbName-2009-09-29-v10.bak';
GO
This will list the contents of the backup - what you need is the first fields that tell you the logical names - one will be the actual database and the other the log file.
RESTORE DATABASE mydbName FROM disk='c:\temp\mydbName-2009-09-29-v10.bak'
WITH
MOVE 'mydbName' TO 'c:\temp\mydbName_data.mdf',
MOVE 'mydbName_log' TO 'c:\temp\mydbName_data.ldf';
GO
At this point you have extracted the database - then install Microsoft's "Sql Web Data Administrator". together with this export tool and you will have an SQL script that contains the database.
MySql have an application to import db from microsoft sql.
Steps:
Open MySql Workbench
Click on "Database Migration" (if it do not appear you have to install it from MySql update)
Follow the Migration Task List using the simple Wizard.
I did not manage to find a way to do it directly.
Instead I imported the bak file into SQL Server 2008 Express, and then used MySQL Migration Toolkit.
Worked like a charm!
In this problem, the answer is not updated in a timely. So it's happy to say that in 2020 Migrating to MsSQL into MySQL is that much easy. An online converter like RebaseData will do your job with one click. You can just upload your .bak file which is from MsSQL and convert it into .sql format which is readable to MySQL.
Additional note: This can not only convert your .bak files but also this site is for all types of Database migrations that you want.
Although my MySQL background is limited, I don't think you have much luck doing that. However, you should be able to migrate over all of your data by restoring the db to a MSSQL server, then creating a SSIS or DTS package to send your tables and data to the MySQL server.
hope this helps
I highly doubt it. You might want to use DTS/SSIS to do this as Levi says. One think that you might want to do is start the process without actually importing the data. Just do enough to get the basic table structures together. Then you are going to want to change around the resulting table structure, because whatever structure tat will likely be created will be shaky at best.
You might also have to take this a step further and create a staging area that takes in all the data first n a string (varchar) form. Then you can create a script that does validation and conversion to get it into the "real" database, because the two databases don't always work well together, especially when dealing with dates.
The method I used included part of Richard Harrison's method:
So, install SQL Server 2008 Express
edition,
This requires the download of the Web Platform Installer "wpilauncher_n.exe"
Once you have this installed click on the database selection ( you are also required to download Frameworks and Runtimes)
After instalation go to the windows command prompt and:
use sqlcmd -S \SQLExpress (whilst
logged in as administrator)
then issue the following command.
restore filelistonly from
disk='c:\temp\mydbName-2009-09-29-v10.bak';
GO This will list the contents of the
backup - what you need is the first
fields that tell you the logical names
- one will be the actual database and the other the log file.
RESTORE DATABASE mydbName FROM
disk='c:\temp\mydbName-2009-09-29-v10.bak' WITH MOVE 'mydbName' TO
'c:\temp\mydbName_data.mdf', MOVE
'mydbName_log' TO
'c:\temp\mydbName_data.ldf'; GO
I fired up Web Platform Installer and from the what's new tab I installed SQL Server Management Studio and browsed the db to make sure the data was there...
At that point i tried the tool included with MSSQL "SQL Import and Export Wizard" but the result of the csv dump only included the column names...
So instead I just exported results of queries like "select * from users" from the SQL Server Management Studio
SQL Server databases are very Microsoft proprietary. Two options I can think of are:
Dump the database in CSV, XML or similar format that you'd then load into MySQL.
Setup ODBC connection to MySQL and then using DTS transport the data. As Charles Graham has suggested, you may need to build the tables before doing this. But that's as easy as a cut and paste from SQL Enterprise Manager windows to the corresponding MySQL window.
For those attempting Richard's solution above, here are some additional information that might help navigate common errors:
1) When running restore filelistonly you may get Operating system error 5(Access is denied). If that's the case, open SQL Server Configuration Manager and change the login for SQLEXPRESS to a user that has local write privileges.
2) #"This will list the contents of the backup - what you need is the first fields that tell you the logical names" - if your file lists more than two headers you will need to also account for what to do with those files in the RESTORE DATABASE command. If you don't indicate what to do with files beyond the database and the log, the system will apparently try to use the attributes listed in the .bak file. Restoring a file from someone else's environment will produce a 'The path has invalid attributes. It needs to be a directory' (as the path in question doesn't exist on your machine).
Simply providing a MOVE statement resolves this problem.
In my case there was a third FTData type file. The MOVE command I added:
MOVE 'mydbName_log' TO 'c:\temp\mydbName_data.ldf',
MOVE 'sysft_...' TO 'c:\temp\other';
in my case I actually had to make a new directory for the third file. Initially I tried to send it to the same folder as the .mdf file but that produced a 'failed to initialize correctly' error on the third FTData file when I executed the restore.
The .bak file from SQL Server is specific to that database dialect, and not compatible with MySQL.
Try using etlalchemy to migrate your SQL Server database into MySQL. It is an open-sourced tool that I created to facilitate easy migrations between different RDBMS's.
