RE: SQL update/insert for a string contain " ' "

["Eyers, Daniel" <daniel.eyers@xxxxxxxxxxxxx>]

Not sure I agree with you here.  Your assumption is that you will *always*
use the AS/400 for your hardware platform.  *and* you assume that you will
*only* connect to AS/400s.  If I wanted to migrate my applications off the
400 onto some other package, I'd be hard pressed to convert the RPG and
COBOL to some other language.  On the other hand, using the '400 as a
development platform (and using SQL) allows me to offer systems on other
platforms with little to no conversion.  Finally, using RPG and COBOL
programs assumes that there is an adequate supply of COBOLers and RPGers.  I
don't know about you folks but I *certainly* don't believe that to be the
case.  In fact, the AS/400 program at the local community college is seeing
significant decline in enrollment... one of the hottest classes: Oracle and
SQL.

Having said that, I think each shop should consider carefully the decision
to use SQL or RPG and COBOL programs as their choice.  Performance is a
crucial issue, however, I find I'm bound by bandwidth, not the response of
the 400.

I respectfully suggest you consider replacing SQL with calls to an RPG or
COBOL program.  While it's a little bit of upfront work, it's far easier to
maintain in the long run, and performs much better.
