Re: Fetch the correct record - pls help

The complete program logic is this

I have a file which has 6 different account numbers. For each of this
account number, I need to check in File1 which has account number, security
and Quantity. I need to sum up the qty field for a combination of Acc num
and security. Once I get the security, I need to search in another file say
File2 for SecRate corresponding to the security which I got from File1.
Apart from the Qty sum up, I have done the program with normal file
operation. But the Qty part seems to be complex without SQL. But I havent
written any SQL so far. So Please show me how to write query for this.
Thanks for all of your time
I need to write the output in a summary file.

Am I wrong or do you need something like this:

Create Table as
(Select Accnum, Security, sum( Qty) Qty
From Table2
Group By AccNum, Security)

Betreff: Fetch the correct record - pls help

Hi All,

I have a scenario like this
I have 3 files , File1, File2, File3.

File1 has account number as a filed
File2 has account number, security and Quantity as fields
File3 has Account number Quantity and Security.

suppose File1 has these values
A
B
C

File2 - Accnum and Sec are keyfileds
Accnum Security Qty
A x 2
A x 3
A x 1
A y 2
A y 3
B y 5
B y 1
C x 2
C x 2

I want to create File3 as a summary. The value should be like this

AccNum Security Qty
A x 6
A y 5
B y 6
C x 4

Without using SQL(I have to change the whole program logic if I go for
SQL)
By using chain or Reade how can I achieve this in mininum steps

I have used a method like this
Point to the first record in file1 and read from there onwards. With
Accnum
as the key readE file2 in a loop( the file has accnum and security as
keufields but am using Accnum alone not sure whether that will cause any
probs) , save the previous security value and in the DoW not
%Eof(File2)loop
check whether the prev saved security = Current security, If so sum up the
Qty fields, else, write to file3. After endDo, I put the write part again
otherwise I was missing the last record which will not enter into the DoW
not %Eof loop.

Anyone has any better idea? My logic seems to be complex.. :(
