Inserting additional columns with Null values
How can we add additional columns with Null values using a mapper snap?
Rationale behind this question: I’m trying to use a Join snap wherein Input 1 has 1 column and Input 2 has 50+ columns, after reading the documentation, the best practice suggests that both the inputs should have consistency else the output would be some unexpected data.
While using mapper snap, I tried adding additional columns but it gives me an error saying that it couldn’t find the column_name (that I’ve added), how do I resolve this error?
Thank you in advance for your help 🙂
Hi @darshthakkar,
Try using the mapper snap with Null-safe access checked. Like in the picture below:
Try this, and let me know if this helps you.BR,
