I work with BDS2006 and I am facing the following problem.
How can I make a class that extends from CoreLab.PostgreSql.PgSqlConnection

as:

type
TConexao = class (CoreLab.PostgreSql.PgSqlConnection)

I always get the error:
[Pascal Error] Conexao.pas(11): E2353 Cannot extend sealed class 'PgSqlConnection'

Is there any solution?

please!

I wuld like to make a class that is independent of DB.

I am build a application that now is working with PostgreSQL and I would like to make a class that just changing a few codes wold work with Firebird ou MSSQL for instance.

Thank you.

Firstly, we have UniDirect .NET fo these purposes.
Secondly, with MS SQL Server you will have the same problem, because its classes are sealed as well.
Thirdly, you may wrap our PgSqlConnection class.
