Re: SQL Help finding missing records

One way to do it is to do the following:
ADDPFCST FILE(ROB/DOUGDTL2)
TYPE(*REFCST)
KEY(ORDERNO)
PRNFILE(ROB/DOUGHDR)
PRNKEY(ORDERNO)
Then look for the messages:
CPD32C5 - Key values for referential constraint are not valid.
... The constraint is in check pending because record 1 in the dependent
file has a foreign key value that does not match the parent key value in
the parent file...
Clear up all those records. Or, use DSPCPCST to find the ones in error.
Once completed then
CHGPFCST FILE(ROB/DOUGDTL2)
CST(...)
STATE(*ENABLED)
and you'll never have another detail record without a corresponding
header.

But, if you're not ready for a reliable long term solution you could try
select orderno from rob.dougdtl2
where orderno not in(select orderno from rob.doughdr)
