Thanks!
To be clear, procedure3a has 2 cursor ‘definitions’ in the declaration section.
My tabs didn’t work for spacing last time. I apologize if that happens again.
Procedure 3a is
Cursor c1 is select ….
Cursor c2 is select….
Begin
For x in c1 loop
Declare
-set some constants
Begin
For y in c2 loop
Do some stuff
End loop;
End loop;
End;
Would c2 still be initialized at the start of the ‘For y’ loop?? I think so
but want to confirm.
Thanks again,

If the cursor is implicit in procedure3a like:
FOR x IN (SELECT * FROM DUAL) LOOP
--do some stuff here
NULL;
END LOOP;
The cursor is initialized when the PLSQL engine goes into FOR ...LOOP statement.

Greetings,
Does anyone know exactly when an explicit cursor is initialized in pl/sql? I
understand I may need to supply more info, but I am no pl/sql wizard and don't
know exactly what info is needed.
I have a package with multiple procedures. One those procedures contains
additional procedures. And one of those additional procedures has some
cursors. Sorta like this:
Package
- procedure1
- procedure2
- procedure3
- procedure3a
- cursor 1
- cursor 2
Would the cursors be initialized when procedure3 is called or when procedure3a
is called? I would guess procedure3a but the developer is seeing some
weirdness where it looks like it's when procedure3 is called.
There is no explicit "open cursor" call. It is used in a for loop, so I think
oracle opens it automagically. But, again, I am trying to determine the
initialization. When is the cursor loaded with data?
Any/all ideas/suggestions welcome.
Thanks,
-joe
