Venkat,
Select ToP 10000 [T_idx],[T_Tag], [T_date], [T_counter] from dbo.[total] ORDER BY T_DATE desc
The above query MAY or MAY NOT give the records with taag ---PO as they might belong to a later data which might not fit into the top 10,000 dates of the table. This shud be the problem.
If you want to see all the data irrespective of the number of rows, then below shud help:
Select
[T_idx],[T_Tag], [T_date], [T_counter]
from dbo.[total]
ORDER BY T_DATE desc
If you need the rows that CONTAIN --PO then folowing shud do it:
SELECT
[T_idx],[T_Tag], [T_date], [T_counter]
FROM dbo.[total]
WHERE T_Tag like '%PO%'
ORDER BY T_DATE desc
If you need just the top 10,000 rows of the above result, then just add a TOP clause as below:
SELECT
TOP 10000
[T_idx],[T_Tag], [T_date], [T_counter]
FROM dbo.[total]
WHERE T_Tag like '%PO%'
ORDER BY T_DATE desc
Thanks,
Jay
