hai folks,

 

i have a table and i update data everyday. now i want to take the product which is new.(ie product entered in the max date - date entered in the last day(say 2008-07-20)

 

 SELECT *
FROM all_product_details
WHERE Product_Id NOT IN (
SELECT Product_Id
FROM all_product_details
WHERE Date_Of_Feed = 2008 -07 -20 )
AND Date_Of_Feed = (
SELECT MAX( Date_Of_Feed )
FROM all_product_details ) 

 

 

now what is wrong with this code.

it doesn't show any error but its not showing the results.

SELECT *
FROM all_product_details
WHERE Product_Id NOT IN (
SELECT Product_Id
FROM all_product_details
WHERE Date_Of_Feed = '2008-07-20' )
AND Date_Of_Feed = (
SELECT MAX( Date_Of_Feed )
FROM all_product_details ) 
LIMIT 1
