Hi:
Are cursors in plpgsql dynamic or static?
For example :
... /* some code */
FOR rec in SELECT f1,f2
FROM table1 WHERE .... LOOP
/* some codes that manipulate table1 */
END LOOP;
Do the result set pointed to by the cursor remains
the same even if performed some data manipulation
inside the FOR..LOOP?
Thank you in advance,
ludwig.
