RE: Branching logic in PL/SQL, positive instead of exceptionDoesn't a cursor
loop only process the loop body when records are found? If this is true
then you will never execute the loop body when the %notfound condition is
true, control has already passed to the next statement following the for
loop.

As an extension of this conversation, if I have eight conditional queries,
eg.:
for i_row in main loop
build sql
declare cursor a select stuff
for a_row in a loop
if a%found
do stuff
elsif a%notfound
declare cursor b select stuff
for b_row in b loop
if b%found
do stuff
elsif b%notfound
declare cursor c select stuff
for c_row in c loop
I'm having trouble with the %notfound and passing control. Do you see what
I've done wrong?
Thanks, Linda

Use SQL%found
It's in the manual. :)

Subject: Branching logic in PL/SQL, positive instead of
exception
Hello,
I'm looking for an example of structured PL/SQL code that does not use
exception logic for branching, but instead recognizes that data is found.
As a bad example,
Select col1 from test.table t where exists (select z.zip from zip_table z
where t.zip=z.zip ) into v_col1 ;
exception
when no_data_found
begin
select col2 from test.table2 t2 where exists (select z.zip from
zip_table z where t2.zip=z.zip) into v_col1 ; ;
exception
when no_data_found
begin
I've checked the books and cannot see how to test for a positive result
instead of a negative (exception) result.
Does anyone have a good example of branching logic on record found?
Thanks, Linda
