PROC SQL: find it hard without Database Schema on SAS Studio

[minhnguyen20]

Hi SAS fellows, 

I am currently finding a bit hard to manipulate on PROC SQL statements without having a visual relationship schema between tables on SAS Studio.  

I already did research on this matter, but little information has been found associated with this matter. Please help advise on this issue. 

Look forwarding to hearing from you. 

Thank you. 

Jas.

Sorry but I don't think that this feature is available as an out of the box feature in SAS.
So you need to rely on any data models created in a separate modelling tool.

Thank you so much !!!

Depending on the database, you can use PROC SQL to query the schema tables and get some insight into the table relationships, indexes, keys, etc.  See this blog post about MySQL, but the same technique can work for other vendors.  Each database has a different set of schema tables that you'll have to research.  Post back into the communities if you have a question about a specific database.
