RE: SQL vs V5R1 and service woes

[rob@xxxxxxxxx]

Thank you for your suggestion.  We're open to much.  Even if new logicals
are required (arrgh - native RPG!).  Joe, judging by many of your past
posts I don't think you can find a use for SQL anywhere.  You also left out
the 11 eval's for moving the fields from one name to another.  But how
could you know there were that many.  And the hassle if someone adds a
field to both of the files, (gotta go change this program).  And the
groundless phobia that rpg programmers have about using the same field name
in more than one file.

C/EXEC SQL
C+ insert into plline2
C+                               (select * from vdline2 where
C+                                                           (vdlpo conca
C+ t h2item) in (select (pdlpo concat plitem) from plline))
C/END-EXEC

or even

C/EXEC SQL
C+ insert into plline2
C+ (select * from vdline2 a where exists (select * from
C+ plline b where a.vdlpo = b.pdlpo and a.h2item = b.plitem))
C/END-EXEC



The equivalent code in RPG:

          READ VDLINE2               90
*IN90     DOWEQ*OFF
VDKEY     SETLLPLLINEL1              91
*IN91     IFEQ *ON                       If in PLLINE
          WRITEPLLINE2R                  Write to PLLINE2
          ENDIF
          READ VDLINE2               90
          ENDDO

Easier to read, and my initial guess is that the RPG runs a bit quicker.

Maybe I'm daft, but I just don't understand why someone would write SQL for
code like this.
