...Create a DBExpress-Connection at Runtime?
Author: Max Kleiner
{
The normal way for Delphi and Kylix is just to check dbExpress,
put a TSQLConnection on a form then double-click the TSQLConnection to display
the Connection Editor and set parameter values (database path, connection name etc.)
to indicate the settings.
But in our example, all goes by runtime (path and login) with dbExpress we don't need
an alias or the BDE either.
}
procedure TVCLScanner.PostUser(const Email, FirstName, LastName: WideString);
var
Connection: TSQLConnection;
DataSet: TSQLDataSet;
begin
Connection := TSQLConnection.Create(nil);
with Connection do
begin
ConnectionName := 'VCLScanner';
DriverName := 'INTERBASE';
LibraryName := 'dbexpint.dll';
VendorLib := 'GDS32.DLL';
GetDriverFunc := 'getSQLDriverINTERBASE';
Params.Add('User_Name=SYSDBA');
Params.Add('Password=masterkey');
Params.Add('Database=milo2:D:\frank\webservices\umlbank.gdb');
LoginPrompt := False;
Open;
end;
DataSet := TSQLDataSet.Create(nil);
with DataSet do
begin
SQLConnection := Connection;
CommandText := Format('INSERT INTO kings VALUES("%s","%s","%s")',
[Email, FirstN, LastN]);
try
ExecSQL;
except
end;
end;
Connection.Close;
DataSet.Free;
Connection.Free;
end;
