At the moment the SQLdb components are part of FPC and Lazarus. They are installed by default in all more or less recent Lazarus versions.
  
At the moment the SQLdb components are part of the Lazarus package, you only need to install them. If you look in the [$LazarusDir]/components you will see a subdirectory SQLdb. Install the sqldblaz.lpk and you will be able to connect to MySQL, Interbase / Firebird and Postgres servers.

Manual installation: if you look in the [$LazarusDir]/components you will see a subdirectory SQLdb. Install the sqldblaz.lpk and you will be able to connect to MySQL, Interbase / Firebird, Postgres, MS SQL and Sybase ASE (if you have FPC 2.6.1+), Oracle servers.

Say you have installed firebird in F:\Program Files\firebird\. The employee.fdb example database will then be installed in the directory F:\Program Files\firebird\examples\ . The IP-adress of your computer is 192.168.2.100.
 
Then entering the following databasename 
 
192.168.2.100:F:\Program Files\firebird\examples\employee.fdb
 
in your IBConnection will connect to the required database.
 
Note that you don't have to enter a value for the hostname property!

Where can I find database components?

At the moment the SQLdb components are part of FPC and Lazarus. They are installed by default in all more or less recent Lazarus versions.

Manual installation: if you look in the [$LazarusDir]/components you will see a subdirectory SQLdb. Install the sqldblaz.lpk and you will be able to connect to MySQL, Interbase / Firebird, Postgres, MS SQL and Sybase ASE (if you have FPC 2.6.1+), Oracle servers. See Install Packages for help on installing packages.

Supported databases

Known issues

Are there other components?

Lazarus and FPC documentation

The Lazarus visual database controls use FPC database code. Please see SQLDB documentation for more information.
