Booth,
Since you're learning...I have to ask, are you taking care to avoid SQL
Injection?
You should always either use static SQL or if you must use dynamic, then
use parameter markers.
Good (static)
exec sql
update mytbl
set myfld = 'XYZ'
where mykey = :hostvar;
Also good (dynamic with parameter marker)
wSql = "update mytbl
set myfld = 'XYZ'
where mykey = ?";
exec sql
prepare mystm from wSQL;
exec SQL
execute mystm using :hostvar;
Bad (dynamic sql w/o parameter marker)
wSql = "update mytbl
set myfld = 'XYZ'
where mykey = " + hostvar;
