RE: strsql not showing all records

SQL != DDS.

Always use an ORDER BY clause on select statements if you intend to
review the result in a particular order. SQL does not guarantee record
order otherwise. What you saw was due to how the query optimizer chose
to access records, based on the different join and where conditions.

I tried both your version of the join and mine - my mistake was with no
order by clause, I was assuming the file would display in session# order
which is not the case. Adding the and CCSESS.SSCCAN ='AV' changes the
order of records returned (drastically). Both ways work and return the
same set, but not in same order. My mistake for assuming something.
Added an Order by clause and now makes sense.

In the older emulator versions, non-displayable characters could break

your

display session.

You can test your theory by outputting to a file instead (F13 --> set
'SELECT output' to 3).

I suspect your issue lies with where you place your selection criteria

(JOIN

clause versus WHERE clause). I suggest moving the selection into the

JOIN

clause and seeing if you get the result set you're interested in,

i.e.:

SELECT CCSESS.SSCCST, CCSESS.SSCCXE,CCSESD.SDCCSS, CCSESS.SSCYMD,
CCSESD.SDCCMJ, CCSESD.SDCCMI, CCSESD.SDCCPS, CCSESS.SSCCAS as AS,
CCSESS.SSCONO, CCSESS.SSDIV,CCSESS.SSLC, CCSESS.SSCLIN,
CCSESD.SDCCSR as SR, CCSESD.SDCCSQ, CCSESD.SDHMS, CCSESS.SSCCAN,
CCSESD.SDCCPK FROM ccsesd join ccsess on sdccss=ssccss AND SsCCSS

1119978 and CCSESS.SSCCAN ='AV'

Subject: strsql not showing all records

Have a join of a large tran file with a master file, joined by a

session

nbr.
Many tran records with a single master record.
Depending upon where I position the file (Where ..) I don't see all

the

records.
If I remove the 'and ccsess.ssccan='AV' I see them (many with 'AV').
But with that "and" selection the file stops showing trans after 2

days ago.

If I change the starting session# in the where clause I can see more

recent

records.
btw-there is non-displayable data in the file (this is comm session

detail)

in one field that is not part of the where clause, and
the msg on the screen says there is some non-displayed.
No err in joblog. V5R4 and sf99504 DB2 Group 14.
SELECT CCSESS.SSCCST, CCSESS.SSCCXE,CCSESD.SDCCSS, CCSESS.SSCYMD,
CCSESD.SDCCMJ, CCSESD.SDCCMI, CCSESD.SDCCPS, CCSESS.SSCCAS as AS,
CCSESS.SSCONO, CCSESS.SSDIV,CCSESS.SSLC, CCSESS.SSCLIN,
CCSESD.SDCCSR as SR, CCSESD.SDCCSQ, CCSESD.SDHMS, CCSESS.SSCCAN,
CCSESD.SDCCPK FROM ccsesd join ccsess on sdccss=ssccss WHERE SsCCSS

1119978 and CCSESS.SSCCAN ='AV'

It's my 'guess' the strsql screen affected by the non-displayable

data, no

error, but also not showing all records.
Any ideas?
