Sql Query- Null values

Hello I have the below query
SELECT 'VA',  CONVERT(char(10),Entered,101),COUNT(RXNO) FROM  HRXS
 WHERE 
-- AND  
 NewRx=1 
 AND PharmID ='VA' and TransType not in('Q','B') and  (CCType IS NULL OR CCType ='C') 
 and Entered is not null and  CONVERT(char(10),Entered,101) between CONVERT(char(10),GETDATE()-31,101) and CONVERT(char(10),GETDATE(),101)
 
GROUP BY CONVERT(char(10),Entered,101)

Open in new window

Somewhere in the data there is null value for the entered field and so its returning no data,but if I comment the where condition on the entered field its returning data.How to handle this?

try the below code

SELECT 'VA',  CONVERT(char(10),Entered,101),COUNT(RXNO) FROM  HRXS
 WHERE 
-- AND  
 isnull(NewRx,'')=1 
 AND isnull(PharmID,'') ='VA' and isnull(TransType,'') not in('Q','B') and  (CCType IS NULL OR CCType ='C') 
 and Entered is not null and  CONVERT(char(10),Entered,101) between CONVERT(char(10),GETDATE()-31,101) and CONVERT(char(10),GETDATE(),101)
 
GROUP BY CONVERT(char(10),Entered,101)

Surendra,
Your code is what I have posted as question.Thanks..

When I comment the convert function on Entered it brings data..as entered somewhere has null data in it


SELECT 'VA',  CONVERT(char(10),Entered,101),COUNT(RXNO) FROM  HRXS
 WHERE
-- AND  
 NewRx=1
 AND PharmID ='VA' and TransType not in('Q','B') and  (CCType IS NULL OR CCType ='C')
 and Entered is not null --and  CONVERT(char(10),Entered,101) between CONVERT(char(10),GETDATE()-31,101) and CONVERT(char(10),GETDATE(),101)
 
GROUP BY CONVERT(char(10),Entered,101)

then why don't you just do this

add the below code inplace of that between

CONVERT(CHAR(10),ISNULL(Entered,GETDATE()-60),101) between CONVERT(CHAR(10),GETDATE()-31,101) and CONVERT(CHAR(10),GETDATE(),101)

Your where-clause is saying "don't show me nulls on the Entered field"... I suspect you want either a null or a range-test:
SELECT	'VA'
,	CONVERT(char(10),Entered,101)
,	COUNT(RXNO) 
FROM	HRXS
WHERE	NewRx=1 
AND	PharmID ='VA'
AND	TransType not in ('Q','B') 
AND 	(	CCType IS NULL
	OR	CCType ='C'
	) 
AND	(	Entered IS NULL
	OR	CONVERT(char(10),Entered,101)
			between	CONVERT(char(10),GETDATE()-31,101)
			and	CONVERT(char(10),GETDATE(),101)
	)
GROUP
BY	CONVERT(char(10),Entered,101)

But you have "Entered IS NOT NULL", so I think the issue is that is a non-null value which does not meet the criteria.  Are you wanting a row even if the count is zero?

In addition, use this to go between dates, noting direct comparisons exclude NULLs already.

Entered >= DATEADD(DD, -31, CONVERT(DATE, GETDATE()))
AND Entered <= CONVERT(DATE, GETDATE())

 
If you are not in SQL 2008, or higher, compatibility, you can accomplish the same thing CONVERT(DATE, ...) is doing with DATEDIFF:
e.g., DATEADD(DD, -31, DATEDIFF(DD, 0, GETDATE()))

If you want row even when there is nothing matching the date range, then use a conditional aggregate.

SELECT 'VA'
     , CONVERT(char(10),Entered,101)
     /* if you have Entered values greater than today, 
        then add the second part to date filter; otherwise, it is unnecessary. */
     , COUNT(CASE WHEN Entered >= DATEADD(DD, -31, CONVERT(DATE, GETDATE())) THEN RXNO END) 
FROM  HRXS
WHERE NewRx = 1 
  AND PharmID = 'VA' 
  AND TransType NOT IN ('Q','B') 
  AND (CCType IS NULL OR CCType = 'C') 
GROUP BY CONVERT(char(10),Entered,101)
;

Surendra you code did not help.
John,
I want data that has no null on the entered field..and its has to be in the date range.
John_VidmarCommented:
Perhaps your data is too old, and that is the reason why you are not getting the records you are expecting.  Your where-clause is saying "only show me records where the Entered date is within the last 31 days"

 and (CCType IS NULL OR CCType ='C')
 and Entered >= DATEADD(DAY, DATEDIFF(DAY, 0, GETDATE()) - 31, 0)
 and Entered < DATEADD(DAY, DATEDIFF(DAY, 0, GETDATE()) + 1, 0)
GROUP BY CONVERT(char(10),Entered,101)
