    Heh... what if there was nothing from yesterday, either?  Peter's solution is good.

    But, why is there even a need to check the date?  Tomorrow's news will likely not happen today.

    Maybe it is some kind of corporate publication system, where web publisher uploads new articles for next week on the friday before. That could be new employees, foreign visits, legal affairs...

    I guess we need more info... this is open to various interpretations

    "IF there is nothing for today then it must fetch yesterday's records"

    I would understand that requirement differently than Peter :

    - display up to 4 records for today

    - if there are any records for today, only records for today may be displayed (even if there is only 1)

    - if no records for today found, display up to 4 records for yesterday

    - records older than from yesterday will never be displayed

    Is this what you need, Asif?

    You mean like this? No need to change existing selects, just add one more select before the others.

    CREATE PROCEDURE SP_news_date

    (

     @news_date datetime

    )

    AS

    SELECT @news_date = (SELECT MAX(en_date) FROM allnews WHERE en_date <= @news_date)

    -- Select the last existing day prior or equal to wanted day and select only records from that day

    -- For local news -0

    SELECT top 4 * from allnews where news_name = 'news' and sub_name = 'Kingdom' and en_date = @news_date ORDER BY en_date DESC

    -- For Middle East new -1

    SELECT top 4 * from allnews where news_name = 'news' and sub_name = 'Middle East' and en_date = @news_date order by en_date DESC

    --For Asia News - 2

    SELECT top 4 * from allnews where news_name = 'news' and sub_name = 'Asia' and en_date = @news_date order by en_date DESC

    --For International news - 3

    SELECT top 4 * from allnews where news_name = 'news' and sub_name = 'International' and en_date = @news_date order by en_date DESC

    Good luck!
