How do I get SQL to talk to an Oracle database? Do I need the JDBC driver JAR from Oracle?
Get the JDBC driver JAR from the vendor, and add a path to it to the class path in the settings for SQL in the Language manager.

Always when I want to use a programme that is using a MySQL database, it forces me to install a MySQL connector or mysql-connector-java.jar.
Why do I need a MySQL connector and how does it work??
JDBC is a library used by your Java programs to access relational databases. You can use it to access Oracle, Informix, Microsoft SQL Server, PostgreSQL, DB2, and other makes of database server, as well as MySQL.
The MySQL connector is a library for, well, connecting JDBC to the MySQL database. If your program were using Oracle, you would use the Oracle connector instead.
This is necessary because each make of database server has its own specific protocol for transporting requests to, and results from, the server to application programs.
So far, I am using mysql for my application. In the process of R&D i want to use oracle for my application and see its performance. I have taken dump of existing database and named it "app.sql". I want to import or restore the same database into Oracle server. Is there any way to do it? or Any migrating tools exist?
or
Is it possible to convert .sql file to .dmp file and import to oracle?
i am using mysql version is 5.5.31 and Oracle version is: 10g.
It happens that the free-to-use (but not open source) Oracle SQL Developer program is capable of importing MySQL databases into the Oracle table server.
This program is pretty convenient for a new Oracle user; it's pure Java so you don't have to muck about with the laughably misnamed Oracle Instaclient stuff. No TNSNAMES.ORA required; just connect.
(Be sure to talk to your finance people before you commit to using the Oracle table server.)
I am trying to make a simple java application that connects to database in Squirrel SQL which I use JDBC connector to connect to but I can't seem to pass making the database in Squirrel. I have my jdbc jar file in place as there is a blue tick indicating my driver is available but but I am not where I might be going wrong. Your shed of insight is highly appreciated. Thank you in advance. Below are pictures of what my setup looks like
Your database is a MySQL one. Instead of "jdbc" driver, use a MySQL one.
It is "MySQL Driver" in the Drivers menu. attach your jar file and then in the Aliases definition, use the MySQL Driver you just configured.
You should either use (or modify) a pre-existing RDBMS driver for MySQL or make your own and label it as a MySQL driver.
The key piece of information that may be missing is the qualified path to your RDBMS home directory. Squirrel needs to be able to find the jar file that contains the JDBC driver for the RDBMS product that you'll be using.
While I haven't set up Squirrel for MySQL, I have set it up for HSQLDB. In the "Extra Class Path" tab of the change driver dialog, I have added and entered the path to my hsqldb.jar file:
C:\App\Dev\Java\DB\hsqldb\2.2.9\lib\hsqldb.jar
This enables the service provider in the JDBC driver package to locate and load the particular JDBC driver for HSQLDB.
Just as a side note, every RDBMS has its own semantics for the connection URL. The one for HSQLDB is unique to it. The one for MySQL (according to the folks at SquirrelSQL) is:
jdbc:mysql://<hostname>[,<failoverhost>][<:3306>]/
<dbname>[?<param1>=<value1>][&<param2>=<value2>]
I have MDB file with data and Mysql database also, I want to insert some specific fields of MDB file to My mysql database, Is there any mechanism to covert it and mention some specific fileds?
If you have Microsoft Access, you can create a link to the MySQL database using the appropriate ODBC driver for MySQL. But it's probably easier to install MySQL Workbench and use the migration assistant (in this case, you'll have to use the ODBC driver for Access).
I need to import records stored in a MySQL Database that I do not maintain into my Sql Server 2005 database (x64)
We should import the records at an interval basis (probably 1 hour).
What would be the best solution to perform the regular import?
Windows Service (using reference MySql.data dll)
Windows Client (could make it automated)
SQL Extended Stored Procedure (is it possible to reference the MySQL.data dll?)
SSIS package - Install MySQL ODBC driver
The problem with #4 is that I do not really want to support the ODBC driver on the sql server.
I'm not sure if you can even reference the x86 MySql.data dll into a x64 sql server process for #3. (Or if you can even reference that dll within a sql server project)
If it were mine to do, I'd go the SSIS route. Sure, you'll "maintain" the ODBC driver on the server, but compared to the maintenance (and development time and headaches) of the other 3 options, that seems to be the simplest route.
What abaut MySql -> *.DAT (per table) -> FTP to WINSERVER -> SSIS to SQL
4.SSIS package - Install MySQL ODBC driver would be the best solution.
