I want to group the lines which have the same caracteristics (Matricule,
Nom, Sexe, DateNaissance, Contrat, Pays) and with period of time
(Debut/start and Fin/end) without interruption of time.
For exemple :
The following three lines : Debut/Start Fin/End
1 VERON Féminin 02/09/1935 CDI commun France
*24/01/1995* 30/04/1997
1 VERON Féminin 02/09/1935 CDI commun France
01/05/1997 30/12/1997
1 VERON Féminin 02/09/1935 CDI commun France
31/12/1997 *31/12/1997*
are transformed into 1 line
1 VERON Féminin 02/09/1935 CDI commun France
*24/01/1995* *31/12/1997*
because same caracteristicsand period of time without interruption of
time (from *24/01/1995* to *31/12/1997)*
The following six lines :
6 BENARD Masculin 01/04/1935 CDI commun Philippines
*02/02/1995* 27/02/1995
6 BENARD Masculin 01/04/1935 CDI commun Philippines
28/02/1995 28/02/1995
6 BENARD Masculin 01/04/1935 CDI commun Philippines
01/03/1995 *12/03/1995*
6 BENARD Masculin 01/04/1935 CDI commun France
*13/03/1995* *30/06/1995*
6 BENARD Masculin 01/04/1935 CDI commun France
*01/01/1996* 30/01/1996
6 BENARD Masculin 01/04/1935 CDI commun France
31/01/1996 *31/01/1996*
are transformed into
6 BENARD Masculin 01/04/1935 CDI commun Philippines
*02/02/1995* *12/03/1995*
6 BENARD Masculin 01/04/1935 CDI commun France
*13/03/1995* *30/06/1995*
6 BENARD Masculin 01/04/1935 CDI commun France
*01/01/1996* *31/01/1996*
because
lines 1-3 identical for caracteristics and without interruption in time
lines 4 and lines 5-6 are not grouped because there is an interruption
in time beetween *30/06/1995 *and *01/01/1996*
Thank you for your help
