I am hoping you can come to my rescue with respect to an issue I am having.
My database has buildings; each building is assigned to a property. SO my gbbuilding table has (for example):
Building Property
1 A
2 B
3 B
4 C
5 D
6 D
And so on.
I have a booking table, which includes a building code. There is a table I need to join to that has several fields in common, but instead of the building code, it has the property code. How the heck do I join these from the SQL statement standpoint?
SQL SELECT *
FROM cmsvbook b LEFT OUTER JOIN cmprovable p
ON b.service_type=p.service_type
AND b.service_detail=p.service_detail
AND b.provider_code=p.provider_code
and b.building_code=p.property_code;
This was how it was written long before I got the view, and might have worked in theory once upon a time. It's now wrong because, for many of my clients these days, the building code and property code can be, and usually are, different. I need to "go through" gbbuilding and swap out the b.building_code for the correct property code that I need.
Sorry for such a idea. Can make sense first to directly download all the tables from SQL to Qlik, and only then to impose conditions and bind them between themselves?
