Just a quick question; after reading the online help and workbench documentation it is unclear if when migrating a database from one server to another it will copy or cut the database? I need the database on both servers.
Thanks in advance for your help.
Migrating a database means to copy all its data and meta data (provided there are equivalents on MySQL side for source types). There's no problem of course if you migrate MySQL to MySQL.

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.

i'm using myaql database for my website which is in my computer.
I'm trying to transfer the database to another computer but I can't find any mysql database file...
My question is if it is possible and how can I do it? (Is there any simple way?)
MYSQL DUMP
It can be used to dump a database or a collection of databases for backup or transfer to another SQL server (not necessarily a MySQL server).
could you guys please explain for me HOW these databases ARE CREATED :
mysql
phpmyadmin
information_schema
performance_schema
I know it's a novice question, I might GUESS the answer for some of them, for example "the reason phpmyadmin database is created" IS because I installed phpmyadmin and this database was created alongside . That's not for sure, so I just need some clarification.
Thank you !
Mysql is a database server. It serves access to databases. It runs on a machine as a service.
Phpmyadmin is a php based tool you install for managing mysql from a web page.
The last two are databases that can be created by an application, such as phpmyadmin, for storing schema information about the rest of the database or tables of a database.
These are the standard set of databases shown when you execute SHOW DATABASES on a clean MySQL install.
mysql - this is created at install of the MySQL server, either by the package management system of your operating system or the script provided as part of the MySQL package
information_schema - meta database, it does not exist on the disk
performance_schema - meta database, but it does store some files on the disk
Any other databases are user/application created.
Recently i came across a tool written in tcl which generates a mysql database without connecting to a server. It uses some c libraries, can this be done in perl? Sorry if this is too basic question. This is completely new to me, couldnt find much information.
EDIT:
By "generates a mysql database" i mean it generates a directory with mysql tables. I can create a soft link to that directory in mysql and query data from that
You can generate an SQL file maually that builds up a database when imported into a mysql database. I would advise against manyually creating binary tables and copying them under mysql's data folder.
On the other hand if you want to use SQL databases locally, without having to run a separate server process try SQLite.
I need to migrate some tables in mysql db to oracle db.
Do you now any tutorial to learn about this migration?
Thanks
You can connect to the MySQL instance from Oracle using Oracle's database link - this link details making the connection from Oracle to MySQL.
Bearing in mind that the MySQL account you use to create the connection will determine access to MySQL data, once the link is created you can work within Oracle to select data from the MySQL tables into the Oracle tables without a need for scripts and such.
Find an ETL tool like Informatica or SSIS to help you. Oracle's Migration Workbench might be the perfect choice, since you're already using Oracle.
