I wrote a query. I am editing data from a registered table of about 37000 and updating it with a cursor. It goes wrong result when I exceed a certain number. This record count is about 12800-12900.

Does anyone have any idea why this is happening? I'm so confused.

Is there any possibility of a restriction when working with the cursor?

  Please provide relevant table layout, indeces and your SQL statement for proper analysis. Your row counts are probably not the problem.

BelgeNo = DocumentNo
CoKey = Company's unique number
Kapsam = type of document
Durumu = status (for document valid=1 invalid=0)
BitisTarihi = End date of the document

Original table has about 37000 records and mixed. I tried to group for 'CoKey' and 'Kapsam' the data in the original table with the following query.

SELECT A.ID, A.BelgeNo, A.CoKey, A.Kapsam, A.Durumu, A.BitisTarihi
FROM Sshyb A
INNER JOIN (SELECT CoKey, Kapsam
 FROM Sshyb
 GROUP BY CoKey, Kapsam
 HAVING COUNT(*) > 1) B
ON A.CoKey = B.CoKey AND A.Kapsam = B.Kapsam
ORDER BY A.Kapsam, A.CoKey

But I may be making a mistake in this query. The number of records is about 25000 when the query runs coz of 'having'. (i have to do this for single records) anyway

Table: ibb.co/5YmPPDH

After that i have cases:

if CoKey = Kapsam

biggest 'end date' must be true, others must be false (in the group as selected in the picture)

if dates are before today all should be wrong in the group

if CoKey != Kapsam

Switch to other group and check same case

In order to do this, I use the cursor as in the query. I am trying to find the groups with the temporary table and update the above. But when it goes above about 12000 records, the update process does not work as I designed it. I am not receiving an error but the update is incorrect.
