how to use CURSOR in DBMS_SQL???

CREATE OR REPLACE PROCEDURE CreateTable(
p_Description IN VARCHAR2
)IS
v_CURSOR NUMBER;
v_CreateString VARCHAR2(100);
v_NumRows INTEGER;
BEGIN
v_Cursor := DBMS_SQL.OPEN_CURSOR;
v_CreateString := 'CREATE TABLE temp_table'||p_Description;
DBMS_SQL.PARSE(v_CURSOR,v_CreateString,DBMS_SQL.V7);
v_NumRows := DBMS_SQL.EXECUTE(v_Cursor);
DBMS_SQL.CLOSE_CURSOR(v_Cursor);

END;

Q1:What's mean of v_Cursor?how to define it?
Q2:what's value v_NumRows will get?
Q3:How to use loop by v_Cursor???:confused:

You need to see the DBMS_SQL documentation urgently.
See http://download-west.oracle.com/docs...sql.htm#998100

Q1:DBMS_SQL cursor is just a number, pointer to a data structure
Q2:In case DDL (which the CREATE TABLE command is), the return value of the EXECUTE function should be ignored
Q3:For the example given, using loop makes no sense, the DDL commands don't return rows. For queries returning rows (SELECT ...) use the FETCH_ROWS function.
