    You need to alias the sum(mark)

    create table totals as select rno,sum(mark) mysum from marks group by rno

    Notice that "mysum" might not be a good column name for you

    I do not see any prob. I created the tavble using this.

    SQL> create table b as select rno,sum(mark) mysum from a group by rno;

    Table created.

    Elapsed: 00:00:00.54

    R u sure "rno, mark are 2 column names of mark table"

    You had no problems creating the table 'cause of you used an alias for your sum() column -as thapush advised, while original poster didn't.

    I misread the section. Thought it was not resolved yet.
