QVD Problem

[#1]

Hello

Monthly i receive a Xls File with a lot of information abour costomers ,  so the goal is to set up a pivot table or reference table to add juste the new entries , to have a message like that : for example ( for octobre 4 customers  are be add , for septembre 5 cust are been added ...)

for this

I use a concatenation of tables + qvd records

1st stage: I load my table reference

2nd stage: a month later, I reload the second example I have 2 new customers

3rd stage: a month later, I reload the table I get and I realize that I have 4 new customers , basically, he can not manage to save the last value, he  reload and show me all news entries

Someone have a idea to solve my problem Thank U

drop table RefSign ;

LET vOldRecords = QvdNoOfRecords('$(FilePath)\QV_Dev\Signalitique_reference.QVD');

CONCATENATE (Signalitique_reference) LOAD Distinct

FROM $(FilePath)\QV_Dev\RefSign.QVD (qvd)

WHERE NOT Exists([ref matricule]);

LET vNewRecords = NoOfRows('Signalitique_reference') - $(vOldRecords);

STORE Signalitique_referenceINTO $(FilePath)\Dev\Signalitique_reference.QVD;

First load the old records, then load the new records and use not exists to check if a customer is new and if it is fill a field with a date of it's first occurence. Perhaps something like this:

LOAD

  @1 as [ref matricule],

  @2 as [ref id ss],

     @6 as [ref nom],

  @7 as [ref prenom],

  '$(ProcessTime)' as [ref Créé le]

  if(not exists(@1,[ref matricule]), monthstart(today())) as MonthFirstOccurence

FROM [$(FilePath)\data\Signalitique PS\24 - SIGNALETIQUE GROUPE*.xls]
