non-Clustered Index
3.can we use query like this "Select * from Table1,Table2;"
Answer Posted / koushik roy
1. A table can only have one primary key.
2. Answer #1 is right. To add it, primary key is clustered
index and when we index a column (non-primary key) it is
non-clustered index.
3. Yes this will act almost as OUTER join
