Getting data from the next row in Oracle cursor
- by Chaotic_one
Hi, I'm building nested tree and I need to get data for the next row in cursor, using Oracle. And I still need current row, so looping forward is not a solution. Example:
OPEN emp_cv FOR sql_stmt;
LOOP
FETCH emp_cv INTO v_rcod,v_rname,v_level;
EXIT WHEN emp_cv%NOTFOUND;
/*here lies the code for getting v_next_level*/
if v_next_level > v_level then
/*code here*/
elsif v_next_level < v_level then
/*code here*/
else
/*code here*/
end if;
END LOOP;
CLOSE emp_cv;
