Question

So how to make a table Read Only in SQL Server?

Answer 1

1. Trigger with rollback trans
2. Read only filegroup
3. Don't grant insert/update/delete permissions

Number 3 is probably best practice. For example, if your connection is db_owner for example then the trigger can be disabled the trigger or move the table to a different filegroup anyway.
