RE: Fetch the correct record - pls help

Hi Nisha
Not knowing the extent of your SQL knowledge/experience
Using Birgitta's example, but substituting your file names
On the command line, type STRSQL and press Enter
This will place you Interactive SQL screen, where you can Enter SQL Statements
Then type the following

Create File3 as
(Select Accnum, Security, sum( Qty) as Quantity
From File2
Group By AccNum, Security)
With Data

And press enter
This will take File2 and group the data by Accnum and Security summing the field Qty

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.. :(
