firebird - requested database driver not found on delphi 7 -


i have installed zeos on delphi 7 , tried connecting firebird database. after put db path object inspector , tried connect it, delphi displays message requested database driver not found. have installed firebird odbc , have set setting on data sources shortcut found on administrative tools still can't connect.

how install driver , need put it?

i used connection when tried connecting firebird database

procedure tform1.zconnection1afterconnect(sender: tobject); begin  end;

i think might misunderstanding zeos , does. not layer lies between application , odbc, ado or whatever database access layer. instead, database access layer allows connect natively several databases firebird, sqlite , others. not need odbc installed.

you can find introduction zeos architecture @ webpage in article.

in order connect firebird need use tzconnection , set following properties:

  • database: example c:/myapp/mydatabase.fdb
  • hostname: localhost if same computer.
  • protocol: should 1 of firebird protocols. firebird-x.x stands protocol access "normal" firebird, while firebirdd-x.x embedded version.
  • user
  • password

you can set additional properties basic connection should it.

regarding error mention, suspect trying use embedded version. in case, make sure dll mentiones @mark in same path app executable. if regular firebird installation make sure path included in system path.
