Is there a way to use EntityFramework 4.3 beta with migrations with MySql database? Can we use migrations with MySql Database? Is it possible to use incremental database development with EF code first without me touching the database
Theoretically yes. Practically you first need to get (or create yourselves) class derived from System.Data.Entity.Migrations.Sql.MigrationSqlGenerator which will be responsible for generating SQL for MySQL. Here is more about customizing (or rewriting) SQL generation.
You can also wait until developers of EF supporting ADO.NET providers include this feature to their packages. For example Devart already started work on their migrations support for thier Oracle, MySQL, PostgreSQL and SQLite.

So, the question is simple - how to make a query from Oracle to MySQL and the other way around. ODBC is out of the question due to slow performance.
Disclaimer: I am the creator of the MySQL DataController plugin.
As far for Oracle to MSSQL, you may create DBLinks for such queries. There are plenty of documentation on how to create a database link on Oracle using the MSSQL Driver.Just google "Database link from Oracle to SQL Server"
If you want to do the inverse, you may use the plugin that we wrote for mysql. The plugin uses Free-TDS which is an opensource project used to communicate to MSSQL. We have updated a blog about that MySQL Plugin, if you need help compiling it we could help you out.
See the following link for a short video and blog about the plugin
http://www.acentera.com/mysql-datacontroller/
There is a mysql client library driver for oracle:
https://docs.oracle.com/database/121/DRDAA/mysql_driver.htm
With regards to MySQL you may be able to use the FEDERATED MySQL storage engine
This may also be useful:
"The DataController project is being designed in order to facilitate and provide an easy database integration between MS SQL, Oracle and MySQL databases. It is being designed to provide real-time performant replication between mysql and other databases.. The code is originally derived from MySQL."

I have created an ERD on MySQL Workbench 6.0.8 CE and managed to export an automated SQL statement using the export option. How can I create a compatible SQL which can be used on Oracle?
Oracle Database and MySQL are normally suited to different use cases. But, if you want to convert the SQL statements created using MySQL workbench to a compatible Oracle SQL Developer, you can do it via a simple operation: Migration. In this case, you will migrate the whole schema. (which is a more recommended solution)
SQL Developer is a free and fully supported product that provides tools and utilities to migrate from MySQL to Oracle. Check here.
If you get stuck on a step, please give me a sign. I'll be pleased to help.
Hope it's useful!
We are migrating a database from MySQL to SQL Server. The migration is pretty straight forward and can be done quite quickly. The project using the existing MySQL database is using Hibernate within Spring MVC. If I migrated the database to SQL Server, and updated the dialect on the Spring MVC side, should the project just work without any other changes to Hibernate queries? Or do we have to make changes to every database call in the data access layer in Spring MVC? I guess I'm trying to find out where the pain points will be and if we could run into any huge issues.
It depends on dependency of your application on database features, are you using stored procedures? MySQL special functions in your HQLs? and ... If you have not used any, I believe everything will go fine
I wanted to migrate my production MySQL database to any other RDBMS. Someone suggested me to use SQLite. I have following queries:
Is there any tool to migrate MySQL to SQLite?
Any GUI tool to manage SQLite databases?
How reliable it is for large production databases?
(I'm not sure about the MySQL to SQLite migration tools. As always with SQL, there are SQL dialects changes that may have to be taken into account, it really depends on your existing databases.)
MySQL and SQLite are fundamentally different in that MySQL is server-based, intended to be used by a client, whereas SQLite is file-based, intended to be used via an API that accesses the underlying files directly. As such, you don't need to manage a SQLite in the same way as you would manage MySQL, because SQLite is an embedded database. There are useful tools for connecting to SQLite databases, one of them is SQLite Manager (it doesn't have to run within Firefox).
This may be an issue for large production databases if you need concurrent access (see this SQLite FAQ.
Old stuff but I needed to convert a MySQL database. I have developed a small snippet in lua to do the basic job of converting the CREATE and INSERT statements. I don't guarantee that it will work in all cases. Just report if it doesn't.
And, by the way, I did the same script in GNU awk some time ago. Lua is about two times faster! As I am a big supporter of gawk that came as a surprise to me.

That's about it. I can always just dump it to csv and read it in, but I was hoping to avoid that.
Since both Interbase and MySql have ODBC drivers, how about using your favorite development environment to write an app that opens each table in the IB database and copies it into the MySql database? There are various languages and IDE's that support data access using odbc.
This would be nicer than using csv because your code could copy the schema during the process of copying each table.
You can use Database Workbench
Cross database development
Use the Schema Compare and Migration
Tools to compare testing and deployed
databases, migrate existing databases
to different database systems.
ps: I don't know why you want to migrate from Interbase to MySQL but you can also take a look to Firebird
