AW: PF data comparision

Hi,

To compare 2 tables I'd use the following SQL statement:

( Select * from Table1
Except
Select * from Table2)
Union
( Select * from Table2
Except
Select * from Table1)

If no rows are returned both tables are identical, that means all columns in
all rows are identical.

Mit freundlichen Grüßen / Best regards

There are lots of fields in the physical files. It's basically
DSPOBJD reports on two different systems and I would like to
compare the source compilation and modified details of each
object. I got the data in two PF's and both are sitting now
in one system.

Perhaps the following [excusing errors in what field names are used
to represent the "source compilation" & "modified"; i.e. represented as
odcdat & odldat respectively, irrespective of existence or meaning of
those as field names]:

/* full outer join on the list [of objects] */
select a.odlbnm,a.odobnm,a.odobtp,a.odobat,a.odcdat,a.odldat
from ODfileA a -- data from system A
left outer join ODfileB b -- data from system B
using (odlibnm, odobnm, odobtp, odobat)
/* to include only mismatches, include the WHERE: */
where a.odcdat <> b.odcdat
or a.odldat <> b.odldat
union all
select b.odlbnm,b.odobnm,b.odobtp,b.odobat,b.odcdat,b.odldat
from ODfileB b -- data from system B
exception join ODfileA a -- data from system A
using (odlibnm, odobnm, odobtp, odobat)
/* to include only mismatches, include the WHERE: */
where a.odcdat <> b.odcdat
or a.odldat <> b.odldat
order by 1,2,3

Note: if /source change date/ is of interest, be aware that the ILE
program objects will not have that detail, which must come from the
modules instead.
