Duplicates in HUB's
Hi
First, tanks for your scipts and the nice web page descibing how to bulid data vaults in Azure. I have tried to build a similar flow, but I see that when I do the initial load to build the HUB table I get multiple lines with the same hashkey. Seems that the Exist function will not work on a blank table. Have you any tips regarding this problem. Im loading from a parquet file into MS DW.
I see that I like to use some other fields in the HUB, so here is my HUB schema(for inspiration) :
CREATE TABLE [dbo].[hub_tractionunit]
(
[hubhashkey] nvarchar NULL,
[loaddate] [datetime] NULL,
[businesskey] nvarchar NULL,
[recordsource] nvarchar NULL
)
WITH
(
DISTRIBUTION = ROUND_ROBIN,
HEAP
)
