What is the output of the following code?
BEGIN FOR i IN 1..3 LOOP IF i < 3 THEN DBMS_OUTPUT.PUT_LINE (TO_CHAR(i)); ELSE i := 2; END IF; END LOOP; END; /
i := 2; * ERROR at line 6: ORA-06550: line 6, column 8: PLS-00363: expression 'I' cannot be used as an assignment target ORA-06550: line 6, column 8: PL/SQL: Statement ignored
The index of a FOR LOOP statement is implicitly declared as a variable of type PLS_INTEGER that is local to the loop.
The statements in the loop can read the value of the index, but cannot change it.
Statements outside the loop cannot reference the index.
After the FOR LOOP statement runs, the index is undefined.
The FOR LOOP statement tries to change the value of its index, causing an error.
