Do you know of any programa that allows me to compare database structures on mysql?
For microsoft sql, I use Sql Delta, which is really great. It lets you compare, and synchronize, tables, views, functions, stored procedures, and data too. It automatically generates sql statements to synchronize both databases.
I was wondering if there's a visual tool like that for mysql (even better if it run on linux)
Checkout MySQL Workbench - http://www.mysql.de/products/workbench/
It's a free and official MySQL app, available for Windows, Mac OS & Linux. It's perfect for create a database schema, which you can deploy to your database (forward engineering). You can even create a schema out of an existing MySQL database or compare schemas.

The access database is on server in folder. I need to create a stored procedure to connect to the access database and update the table data. It can be truncate then an insert. It is connecting via stored procedure to the access database i cannot figure out. It has to be done via a job on a schedule.
MySQL (the Sun- then Oracle- owned product) lacks the plumbing to connect to external tables unless they're on other MySQL servers. That is, it only has a FEDERATED storage engine. So, with MySQL you'll have to find some other way to handle your requirement; a MySQL event or other stored code cannot hit your Access tables.
MariaDB, the MySQL fork, has a CONNECT storage engine. It allows the server to hit external tables via ODBC, so you can hit Access with it. MariaDB is almost entirely compatible with MySQL, so maybe you can replace your MySQL server with it. The CONNECT documentation says this, however.
...these table types cannot be ranked as stable. Use them with care in production applications.
To me, that warning means don't do it!. Especially with a busy business-critical application (like a credit department might use) you don't want even a little bit of instability. If you truncate a table and then the reload fails, you'll be able to hear users yelling from the next county.
Your requirement is, I believe, to extract the contents of one (or more) Access tables and import them into a MySQL table. That kind of operation is called extract-transform-load etl. It seems you use SSIS for the purpose. That should work, because SSIS can connect to Access (of course) and to MySQL via the Connector/net or Connector/ODBC drivers.
But, scheduled SSIS packages get run from SQL Server database servers. You didn't say you have one of those at your disposal. If your org does have a production SQL Server instance, you can put your Access - to - MySQL package into it.
Otherwise you will have to figure out a way to run your scheduled etl job without relying on a database job (or event, as they're called in the MySQL world). For that you'll use the Task Scheduler on Windows, or a cronjob on a UNIX-derived OS like Linux or FreeBSD.
I bet you can do this work reliably from a Windows PowerShell script or a Linux shell script.
I want to use PgSql in my new proyect, but I have old tables I need to use. Which is the best way to share tables between both databases? Is there any way of synchronizing several tables between databases?
You can use SQLWays that convert T/SQL stored procedure, function, trigger, database schema (DDL) and data from Microsoft SQL Server to PostgreSQL.
See this link : Migrate from MySQL to PostgreSQL

Full Convert 6.4

I have created database in microsoft sql server 2005 can i use that particular database in mysql server 5.0 .
There is no common way to perform such kind of migration because of much of differences between these two RDBMS.
The quick suggestion can be: export you MSSQL database into SQL file, open it via favorite text editor, remove MSSQL specific instructions, and load into MySQL using mysql console tool.
This way should be OK for non-complex databases without complex constraints, foreign keys and stored procedures.
Otherwise, you'll need to rewrite these type of database artifacts using MySQL dialect.
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

ps: I don't know why you want to migrate from Interbase to MySQL but you can also take a look to Firebird
