I'm trying to update a DE in marketing cloud based on a query in Automation Studio. It validates and appears to run when I click Run Once but my target DE never updates any records. I'm relatively new to SQL and Marketing Cloud so bare with me. This is probably a basic query but this is a test to expand on later.
a.order_number as [TRANSACTION_KEY]
FROM IGO_PURCHASES AS a
INNER JOIN TEST_PI AS c
ON c.TRANSACTION_KEY = a.order_number
TEST_PI is a new DE with two fields, both which are blank. My expected result is to take order_number values from DE IGO_PURCHASES and populate TRANSACTION_KEY values with those queried results.
Like I said, it runs, but TEST_PI records remain at 0. Any help would be greatly appreciated.
example of the table structure for IGO_PURCHASES
Name Data Type Length Primary Keys Nullable Default Value Sku Text 256 YES NO N/A order_number Text 256 NO YES N/A user_id Text 256 YES NO N/A Timestamp Date N/A YES NO N/A
example of the table structure for TEST_PI
Name Data Type Length Primary Keys Nullable Default Value TRANSACTION_KEY Text 256 YES NO N/A PRODUCT_KEY Text 256 NO YES N/A
