I have a Calisma Database and it has DosyaNo and SiraNo columns.
I want to set SiraNo where DosyaNo is same for example
DosyaNo ____________SiraNo
0.00000000__________1
0.00000000__________2
0.00000000__________3
0.00000000__________4
0.00000000__________5
---------------------
0.10000000__________1
0.10000000__________2
0.10000000__________3
0.10000000__________4
0.10000000__________5
-----------------------
0.70000000__________1
0.70000000__________2
0.70000000__________3
------------------------
7.10000000__________1
7.10000000__________2
You can use CTE for that
WITH cte AS
(
SELECT DosyaNo, SiraNo,
ROW_NUMBER() OVER (PARTITION BY DosyaNo ORDER BY (SELECT NULL)) rnum
FROM table1
)
UPDATE cte
SET SiraNo = rnum

LEAD([DepartmentName]) over (Partition by [EmployeeNumber] order by [ASofDate]) as NewDepartmentName,
LAG([DepartmentName]) over (Partition by [EmployeeNumber] order by [ASofDate]) as OldDepartmentName

How can I write this query without TOP and Limit only use the SQL
You just sort the data one way, grab the records you want, then sort it the other way:
SELECT SOME_FIELD
FROM (SELECT st.*
FROM SOME_TABLE st
ORDER BY SOME_FIELD DESC)
WHERE ROWNUM <= 7
ORDER BY SOME_FIELD ASC
