Differentiate source systems

richard24best — Wed, 25 Nov 2020 16:16:04 GMT

Hi All, I have scenario where our Qlikview is connected to SQL server (with 2 different SQL scripts/sources). How do I differentiate the 2 source systems in Qlikview? Appreciate your help For example SQL is retrieving Source system A and B, is it something I need to create a variable Sourcesystem = A / B

It depends - are those tables independent or joined/assciated or concatenated respectively a mix of them? What is the aim to differ between them?

Hi Marcus,

Thanks for asking.

Well, these are independent tables.

While deriving Source A data, we have defined in SQL 'A' as Sourcesystem and for Source B data, we have 'B' as Sourcesystem.

Hence need help on how to pull this sourcesystem as 'A' or 'B' in Qlikview.

If the tables are independent or if they will be concatenated (union in sql) it's usually enough the add the source-information as an own field, like: 'A' as source (if your database has features to return beside the data also table-information respectively meta-data you may use them).

If tables are associated or joined the above approach won't work. In this case the information must be included in the fieldname - quite common for this is to use: Qualify *; - but the approach has the disadvantage that it increased the lenghts of the fieldnames - especially if it's applied over multiple stages. And quite often it doesn't improve the readability and the comprehension from the users to the usually rather user-unfriendly fieldnames.

An alternatively might be to add the source (and further) information to tags/comments of the tables and fields.
