Declaring a cursor in a procedure based on a passed in parameter
I am trying to pass in a table name into a procedure and use that table name as part of a cursor.
It seems like I need to declare/initialize the cursor after the BEGIN to be able to use the table name in the cursor. I am not sure if my declaration for the cursor is the problem or if this needs to be done a different way.

create or replace procedure something(table_name_in varchar2)
as
sTable varchar2;
sConstraint varchar2;
c1 sys_refcursor;
BEGIN
OPEN c1 FOR select table_name, constraint_name from user_constraints where table_name = table_name_in;
LOOP
FETCH c1 INTO sTable, sConstraint;
EXIT WHEN c1%NOTFOUND;
END LOOP;
CLOSE c1;
EXCEPTION
WHEN NO_DATA_FOUND THEN
NULL;
WHEN OTHERS THEN
-- Consider logging the error and then re-raise
RAISE;
END;
i think if you use UPPER ( table_name_in ) or if you ensure that table_name_in variable will always have values in CAPITAL LETTERS then your code should work fine.
sTable varchar2;
sConstraint varchar2;
try to declare as
sTable user_constraints.table_nam e%type;
sConstraint user_constraints.constrain t_name%typ e;
sConstraint varchar2;
try to declare as
sTable user_constraints.table_nam
sConstraint user_constraints.constrain
sTable varchar2; -- this declaration is incorrect. It should always have length or as given already use %type
sTable varchar2(30); -- if you want to hard code then it should be something like this. change it for other variable as well
sTable varchar2(30); -- if you want to hard code then it should be something like this. change it for other variable as well

Thanks! Exactly what I was looking for. It really wasn't/isn't obvious that curr_table doesn't need to be declared but that is where my problem was.
