You can certainly load PK values into QV, but if they are well formed 'no-information/logic free' keys, you may not need them in QV.</P><P></P><P>A key in QV is a field that exists in more than one table and is the basis of the association between the tables. A key may be designated as a "perfect key" in the table if there is one unique value of the key field for each row in the table and that is conceptually similar to a PK in a normal form database.</P></BODY></HTML> Tue, 12 Apr 2016 13:23:55 GMT https://community.qlik.com/t5/QlikView/primary-keys-ion-QV/m-p/1019037#M635422 jonathandienst 2016-04-12T13:23:55Z Re: primary keys ion QV https://community.qlik.com/t5/QlikView/primary-keys-ion-QV/m-p/1019038#M635423 <HTML><HEAD></HEAD><BODY><P>Useful reading: <A href="https://community.qlik.com/qlik-blogpost/4707">QIX - A Forgiving Engine</A></P></BODY></HTML> Tue, 12 Apr 2016 13:27:40 GMT https://community.qlik.com/t5/QlikView/primary-keys-ion-QV/m-p/1019038#M635423 Clever_Anjos 2016-04-12T13:27:40Z
