Hello GeoNet,
I am trying to create a Database View that have a simple join from one layer with spatial information with another table in SDE. l am not sure what I am missing here.
For example:
layer1 is the spatial layer
layer2 is the table layer
I'd like to join them with the 'joinID' field from layer1 and the 'PROJECT_ID' field from layer2.

This is the error message I've received:

Any pointers are greatly appreciated please.
Thanks a lot!
