Lisa,

There is one and only one case I've seen where the implicit cursor attribute returned an unexpected value. In this case it was not Oracle's fault, but the developers. What he had was basically the following (shortened for brevity & to save the list some work):

for a in (select <a_pile_of_columns> from <user_defined_table>) loop

if(a.<some_column> = <a_value>) then

        update <results_table>
      end if;

if(SQL%ROWCOUNT > 0) then .....
end if;
end loop

Care to guess what SQL%ROWCOUNT was referring to? It depended on whether or not the update statement fired. Kind of weird, but if you read the PL/SQL manual it's clear.

Lisa, so far sql%rowcount has returned me the right values.

Hello all,

One of the developers here is having trouble using this cursor attribute. He swears up and down the statement is correct and should be updating rows. I tried to recreate his problem and wasn't able to. Below is an example of the type of code I'm referencing.

Has anyone ever seen the implicit cursor attributes screw up and return wrong values? I don't believe I ever have. Any responses are appreciated.

Thanks
