Opens a connection to a database using the connection string parameters.
procedure Open; override;
virtual __fastcall Open();
Open opens a connection to a database using the ConnectionString parameters. The ConnectionString property must be set before opening a connection. You must separate keyword value pairs by semicolons (;). Names are not case sensitive. Most applications only need to set the ConnectionName name property, which identifies a collection of properties stored in a dbxconnections.ini file. Alternatively, an application can specify all properties from the dbxconnections.ini and dbxdriver.ini file for the database being connected to.
