    Using TO_DATE format in select statement

    Hello,
    Pls am using TO_DATE function in my select stt. But its returning the wrong dates for me. In the database a text field contains 20021231. i want to convert it to date format and am using this format

    TO_DATE(ind_val,'dd/mm/yyyy')

    I want the format above to return 31/12/2001 from 20021231 but its returning 20-feb-31.

    Pls anyone have and idea how i can return exactly dd/mm/yyyy from 20021231.

    you need to specify the format of the data in your column

    TO_DATE(ind_val,'yyyymmdd')

    and set your nls_date_format to

    alter session set nls_date_format = 'DD/MM/YYYY' to display it how you want it

    A word to the wise:

    If you're experimenting, testing etc in SQL*Plus then setting NLS_DATE_FORMAT, as suggested by davey, is ideal.

    If you're writing an "application", the only sure-fire way to get it to always work, is to fully specify the date formats as engiri did.
