Hi: Can any one please tell me how to i use the recordcount in that query
select clt_ref_no as CFG_ACCOUNT,
(case  
         when r.status_code in ('400','404','407') then 'OVBK'
        when r.status_code in ('210','420','430','470','630','475') then 'OVUN'
        when r.status_code in ('435','438') then 'OVRC'
        when r.status_code in ('450') then 'OVDC'
        when r.status_code in ('487','485') then 'OVFA'
        when r.status_code = '491' then 'OCAC'
        when r.status_code = '510' then 'OSIF'
        when r.status_code='520' then 'OPIF'
        else 'CHECK STATUS'
       END) as REASON,
(SELECT LONGSTR FROM DBTRUDF U WHERE R.DEBTOR_ID=U.DEBTOR_ID AND LABEL='BANKRUPTCYCHAPTER') AS BANKRUPTCYCHAPTER,
(SELECT LONGSTR FROM DBTRUDF U WHERE R.DEBTOR_ID=U.DEBTOR_ID AND LABEL='CASENUMBER') AS CASENUM,
CONVERT(CHAR(10),(SELECT DATE1 FROM DBTRUDF U WHERE R.DEBTOR_ID=U.DEBTOR_ID AND LABEL='FILEDATE'),101) AS BKTFILEDATE,
CONVERT(CHAR(10),(SELECT DATE1 FROM DBTRUDF U WHERE R.DEBTOR_ID=U.DEBTOR_ID AND LABEL='DECEASEDDATE'),101) AS DATEOFDEATH,
    STATUS_DESCR AS COMMENTS,
    substring(DEBT_DESCR,(LOCATE(DEBT_DESCR,':',1)+1), 30) AS ORIGINALACCOUNT
FROM DEBT_VIEW S JOIN DBTR R ON S.DEBT_ID=R.DEBTOR_ID
WHERE CLT_ID LIKE 'IDTC%' AND R.STATUS_CODE>='400'  AND R.STATUS_DATE> '04-11-07'

Thanks.

I am not sure what you are asking.  Is this in a stored proc and you want to know how many rows were returned?

Immediately after DML statement, the global variable @@ROWCOUNT will tell you how many rows were returned/affected by the operation.

No its not in a stored procedure. If you please tell me how to i use the count(*) in the query which gives me only a total number of row count in the query?
Thanks.

COUNT(*), like the other aggregate functions (MIN, MAX, AVG, etc) only works properly in the context of a query with a GROUP BY clause.

Since you are returning individual rows, the COUNT(*) aggregate does not give you what you want.  Even if you added the GROUP BY in such a way it did not affect your query otherwise, you would simply get "1" for the COUNT(*) on each row.

Depending on what you are using for client software, you could put the COUNT(*) in a COMPUTE clause.  Unfortunately, COMPUTE is a Sybase-only extension to SQL that never gained wide popularity or support so very few tools know what to do with it.

Your best bet is to put the whole thing in a SQL block and return the value of @@ROWCOUNT as a second result set.  For example....

BEGIN
 SELECT clt_ref_no as CFG_ACCOUNT,
     o
     o
  WHERE CLT_ID LIKE 'IDTC%' AND R.STATUS_CODE>='400'  AND R.STATUS_DATE> '04-11-07'

  SELECT @@ROWCOUNT as RowCount
END

Regards,
Bill

If you just want to test the number of rows this query will return you could use this:

SELECT COUNT(*)
FROM DEBT_VIEW S JOIN DBTR R ON S.DEBT_ID=R.DEBTOR_ID
WHERE CLT_ID LIKE 'IDTC%' AND R.STATUS_CODE>='400'  AND R.STATUS_DATE> '04-11-07'

But this would have to be run independent of your original query. You could run them one afer the other by seting the count to a variable, but in effect you are executing the query twice.
