Help with EXECUTE IMMEDIATE and DROP

Question

Hi all,
we are trying to create a procedure to do the following:
* We have in the database some tables named like C$_XXXXXXXXX
* We want to drop some of these tables that have a common prefix (f.e C$_1203101)
DECLARE
v_sql VARCHAR2(300);
BEGIN
SELECT 'DROP TABLE ODISTAG.'|| TABLE_NAME ||';' INTO v_sql FROM USER_TABLES WHERE TABLE_NAME LIKE 'C$_1203101%';
EXECUTE IMMEDIATE v_sql;
END;
But we get this error:
Error report:
ORA-00911: invalid character
ORA-06512: at line 5
00911. 00000 - "invalid character"
*Cause:    identifiers may not start with any ASCII character other than
letters and numbers. $#_ are also allowed after the first
character. Identifiers enclosed by doublequotes may contain
any character other than a doublequote. Alternative quotes
(q'#...#') cannot use spaces, tabs, or carriage returns as
delimiters. For all other contexts, consult the SQL Language
Reference Manual.
*Action:
Any help on that please?
Thanks!

This will not work if you fetch more than one row..instead you can do this..
DECLARE
     v_sql VARCHAR2(30000);
BEGIN
     for c2 in (
                    SELECT 'DROP TABLE ODISTAG.'|| TABLE_NAME drp
                    FROM USER_TABLES WHERE TABLE_NAME LIKE 'C$_1203101%'
     loop
          v_Sql := c2.drp;
          EXECUTE IMMEDIATE v_sql;
     end loop;
END;
