How can I update columns in the SQL Server table that have foreign keys?

[ Edited ]

I have a follow up question based this thread: https://communities.sas.com/t5/SAS-Data-Management/SQL-Server-pass-through-merge-update-insert/td-p/...

 

How can I update columns in the SQL Server table that have foreign keys? It errors whenever I attempt to do so without a specific fix, probably because it in the pass through section. Is there specific syntax to use on foreign keys?

Not sure what you ate getting at. Pass through means that you are operating entirely in the external database, do this should not be a SAS question imo.
What do you mean by a specific fix?
FK is a standard DB concept, and how to update data structures using those is described in numerous DB publications.

Foreign keys are defined in a database to maintain referential integrity between tables. If you are getting such errors then it probably means the FK-referenced table needs to have the new data value added to it before you update your primary table. Talk to your DBA to understand what is going on, and what order you need to update tables in.
