Connect to most popular databases

The Database Connection component implements generic live database connection. By using this component you can connect to different databases via any supported database library. Use Database Connection if you want to work with different database types.

DBConnection1.ConnectionType := cnIBX;
with DBConnection1.ConnectionOptions do begin
   DatabaseName := 'database';
   HostName := 'server';
   UserName := 'user';
   Password := 'password';
DBConnection1.Connected := True;

IBSQLExec1.DBCConnection := DBConnection1;

You can always use database specific connection component e.g.: DB ConnectionADO, DB ConnectionIBX, DB ConnectionBDE etc. This feature allows you to bind standard VCL connection object to Database Comparer components.

DBConnectionADO1.Connection := ADOConnection1;
DBConnectionADO1.Connection.ConnectionString := ConnectionString;
DBConnectionADO1.Connected := True;

MSSQLExec1.DBCConnection := DBConnectionADO1;
