minimum user permissions required for alter table in ssms

Question

Initially I could do everything in SSMS graphically, but now I am unable to ALTER table , create a KEY and CONSTRAINTS . I get the error message : " Unspecified error (MS Visual database Tools) ". I only can do this now by TSQL.

I believe that my permissions were changed! I think I had permission db_owner and now I have db_ddladmin, db_datareader and db_datawriter.

It's possible to do the commands above graphically with different permissions without having db_owner permission?

Answer 1

check under tools/options/designers/table and database designers

the option "prevent saving changes that require table re-creation" must be off
