Load Script

kamielrajaram — Thu, 19 Dec 2013 08:12:49 GMT

Good day,

I have noticed something quite strange. I have a customer table and customer phone table. In the customer phone table there is a row for each phone type, home, work and cell. What I require is all the details as a single record per customer. I load the customer details, then left join to the customer phone table using where exists custid and for the cell phone type, the do the same for the other phone types. What i have noticed is that if there is no cell phone record, then the work and home number are not populated. I am currently different load orders.

Not sure what I am missing

Thank you

Kamiel

Something like this:

Customers:

Load CustomerID, ...other_fields... from Customers

join load CustomerID, PhoneNumber as Home

from CustomerPhoneTable

where PhoneType = 'Home';

join load CustomerID, PhoneNumber as Work

from CustomerPhoneTable

where PhoneType = 'Work';

join load CustomerID, PhoneNumber as Cell

from CustomerPhoneTable

where PhoneType = 'Cell';

Change field names and the values in the where clauses to whatever matches your situation.
