RE: SQL vs V5R1 and service woes

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.
