I am sure I have done this before, but it escapes me and I cannot find code
where I have done it.
I have a file I need to create, stripping out duplicate records. The problem
is I have a quote file with overlapping quotes Example:
Quote # Vendor Part Number Dates from / to
1234 abcd Item1 01/01/2012 to 09/30/2012
2345 abcd item1 07/01/2012 to 12/31/2012
For the application I have, I need to select ANY one of the 2 above.
I have created a temporary file QUOTE2 and am then using the INSERT to fill
the new file QUOTE2 with unique records.
The command is:
Insert into QTEMP.QUOTE2 Q2
( Select A3.QTCO, A3.QTVEND, A3.QTPN, A3.QTPN
from myLib.QUOTE A3
where current date between A3.QTDTEF and A3.QTDTEX
And A3.QTCO || A3.QTVEND || A3.QTPN not in (
Select Q1.QTCO|| Q1.QTVEND ||Q1.QTPN from QTEMP.QUOTE2 Q1)
The difference here is I am trying to insert records into the same file that
I am checking for duplicates (QTEMP.QUOTE2).
My result contains the duplicates. It appears the system is building up a
work file before it starts the INSERT. As the work file starts off being
empty, the NOT IN has nothing to check against and so writes all records
into QUOTE2. I would like it to check back against QUOTE2 for every INSERT.
I need a new way or some way similar to a declare cursor using the SENSITIVE
My code is running in a script using RUNSQLSTM so I am limited by what I can
do in the script.
