Which one of the following is a reason that an INSERT statement might cause an error instead of executing correctly? 1. The INSERT statement was attempting to insert a record into a view that was created from more than one table. 2. The INSERT statement was attempting to insert a record using a combination of constants and values from an existing table. 3. The INSERT statement was attempting to insert a record with a non-NULL value into a table that has that column defined as NULL. 4. The INSERT statement was attempting to insert a record into a table by selecting a record from that same table. 5. The INSERT statement was attempting to insert a record into a view rather than a table.

Hi, Can anybody please explain me the flow of the below query. I am not able to understand how this query works. This query is for finding the Nth highest salary.. SELECT DISTINCT (a.sal) FROM EMP A WHERE &N = (SELECT COUNT (DISTINCT (b.sal)) FROM EMP B WHERE a.sal<=b.sal); If N = 2 then second highest salary will be the o/p. If N = 3 then third highest salary will be the o/p. and so on.. Thanks, Nitin
