Hi,
If you are already on release V5R4, you may use the OLAP-Ranking function
DENSE_RANK.
Select FiscYear, CtlGrp, SrcCode,
Dense_Rank() Over(Order By FiscYear, CtlGrp, SrcCode) as SEQ
From YourTable
Order By FiscYear, CtlGrp, SrcCode
Mit freundlichen Grüßen / Best regards

Betreff: Another SQL Question
Given the following data:
FISCAL CONTROL SOURCE SEQ
YEAR GROUP CODE #
2,007 1 AP 0
2,007 1 AP 0
2,007 1 AP 0
2,007 1 JE 0
2,007 1 JE 0
2,007 1 JE 0
2,007 1 CS 0
2,007 1 CS 0
2,007 1 CS 0
2,007 1 CS 0
2,007 1 CS 0
2,007 2 JE 0
2,007 2 JE 0
2,007 2 JE 0
2,007 2 AP 0
2,007 2 AP 0
2,007 2 AP 0
2,007 2 AP 0
2,007 2 AP 0
Is there any method using dynamic SQL (no user defined functions or any
other type of sql program), to set a sequence number so that when Year,
Control Group or Source Code change, the value will be incremented by 1
starting at 1? I have tried the Row_Number() Over function, but have not
been able to get it to do what I want.
The desired result would be:
FISCAL CONTROL SOURCE SEQ
YEAR GROUP CODE #
2,007 1 AP 1
2,007 1 AP 1
2,007 1 AP 1
2,007 1 JE 2
2,007 1 JE 2
2,007 1 JE 2
2,007 1 CS 3
2,007 1 CS 3
2,007 1 CS 3
2,007 1 CS 3
2,007 1 CS 3
2,007 2 JE 4
2,007 2 JE 4
2,007 2 JE 4
2,007 2 AP 5
2,007 2 AP 5
2,007 2 AP 5
2,007 2 AP 5
2,007 2 AP 5
