RE: SQL Statements in ILE RPG

["Haas, Matt" <Matt.Haas@xxxxxxxxxxx>]

I'd suggest checking SQLSTT instead of SQLCOD. If the first two characters are 
00 or 01, the data's safe to use. 02 indicates no records found (or end of 
cursor). Anything else indicates an error.

I use this data structure to make testing these values a little easier:

DSQLState         DS               
D SQLClass                1      2A
D SQLStateCode            3      5A

All you have to do is set SQLState = SQLSTT and then you can just check 
SQLClass.

SQLCOD's have changed in the past since they're unique to DB2/400 but SQLSTT's 
are based on a common standard that is less likely to change. One final point 
on SQLSTT vs. SQLCOD is that a given SQLCOD can map to more than on SQLSTT 
which means that SQLSTT's are usually more helpful when debugging.

Subject: SQL Statements in ILE RPG 


I wrote a nice little embeded SQL in a RPGLE program.  I tested the 
statement in STRSQL and got 2965 rows returned.  When I run it in my RPGLE I 
get 39 rows...

C/exec sql declare c1 cursor for
C+    select cnme, bsdst#, substring(bssdat,1,6), sum(bsexbs)
C+      from bsf100s
C+      join brcm    on bsdst# = rcusno
C+      join rcm     on bsdst# = ccust
C+     where substring(bssdat,1,6) between :strdat and :enddat
C+       and bsrtyp = 'S'
C+     group by cnme, bsdst#, substring(bssdat,1,6)
C+     order by cnme, bsdst#, substring(bssdat,1,6)
C/end-exec

C/exec sql
C+  open c1
C/end-exec

C     sqlcod        doune     0
C/exec sql
C+ FETCH NEXT FROM C1 INTO :icnme, :idst#, :isdat, :iexbs
C/end-exec

I changed doune 0 to doueq 100 and got most of my expected data.  BUT I'm 
still missing some.

The SQLCODE is also set by the database manager after each SQL statement is 
executed as follows:

If SQLCODE = 0 and SQLWARN0 is blank, execution was successful.
If SQLCODE = 100, no data was found. For example, a FETCH statement returned 
no data, because the cursor was positioned after the last row of the result 
table.
If SQLCODE > 0 and not = 100, execution was successful with a warning.
If SQLCODE = 0 and SQLWARN0 = 'W', execution was successful with a warning.
If SQLCODE < 0, execution was not successful.
A complete listing of DB2 UDB for iSeries SQLCODEs and their corresponding 
SQLSTATEs is provided in the SQL Messages and Codes book in the iSeries 
Information Center.

I tried reading the "SQL Messages and Codes book" and I think Greek would be 
easier to understand.

IF SQLCOD is not equal 0 ang not equal to 100 can I still use the data?
