Hello Experts,

I'm working on Reconciliation Report, where I'm missing Logic:

1. I need to Check the Record exists in given  Date Range, if no records exists. I need to search beyond another nearest date range from  the table datetime field.

Try using
 IF (SELECT COUNt(*) FROM TableName WHERE Date between '08-20-2010' and '08-21-2010')  > 1
BEGIN
SELECT Statement
END
ELSE
BEGIN
SELECT Statement
END

OR
 you can use IF EXISTS as in the Link

OR
you Can use CASE WHEN in where Clause of select statement depending on the requirement

you could use the exists function in an If, or Join

Exists(      
SELECT X FROM X WHERE X)

This is my requirement, I need to get the closet datetime value if the given date ranges doesn't get any results.

The datetime value from the table must be close eniough to get me the results.

e.g

Quantity

ID  datetime        Qty
1   08/02/2010    100
2   08/06/2010    300
3   08/21/2010    400


If user has give date = 08/07/2010  it should check the nearest datetime(Can be greater or lesser) so that it can find results.
