    Fetching rows fastly can be done using indexes can only be done, if you use indexing for one column there is not at all a problem of accessing the data faster.
    if u use more than 1 column on indexing, it might be problem
    thanks

    Dear susarlasireesha,

    Try query optimizer HINTS.
    You can choose between Default, /*+ CHOOSE */, /*+ RULE */, and /*+ FIRST_ROWS */.

    I hope this will help you solving your query.

    Have a pleasant time.

    if we define a unique or primary key on a column in a table automatically a unique index will be created.No need to define manually.
