Hi there, I am using the following Cursor in order to populate multiple tables.
/*
This script populates the following tables in Cx. They are listed in the order that they import.
Asset
AssetAddress
AssetCompany
Import Referance
*/
--Cursor Variables

DEALLOCATE Asset_Cursor
Now the help I require is surrounding populating my third table -
-- Populate the AssetAddress Table with the relevant data
INSERT INTO AssetAddress (AssetId,AddressId,EffectiveFromDate)
VALUES (@id,@Address,CAST(GetDate() as date))
The AddressID in this table (AssetAddress) is NOTNULL, so I only want to only populate this table if the @address variable I declared is not null.
I need to remove these otherwise the import with fail.

Just worked it out -
As the ASSET table is now populated - I can use the following
-- Populate the AssetAddress Table with the relevant data. Only if the AddressID is populated
INSERT INTO AssetAddress (AssetId,AddressId,EffectiveFromDate)
SELECT a.AssetID,a.AddressId,CAST(GetDate() as date) FROM Asset a WHERE a.AddressId IS NOT NULL
February 10, 2016 at 6:50 am
Or this?
-- Populate the AssetAddress Table with the relevant data
IF @Address IS NOT NULL
INSERT INTO AssetAddress ( AssetId, AddressId, EffectiveFromDate )
VALUES ( @id, @Address, CAST(GetDate() AS date) );
