Create sequence with var as start number

Question

Hi,
I would like to create a squence that starts with a number, which would be the
maximum number I got from DEPTNO column of TEST table +1, so I have the following
pl/sql stmts:
VARIABLE g_max_number NUMBER;
DECLARE
v_max_number NUMBER;
BEGIN
SELECT max(DEPTNO) INTO v_max_number FROM TEST;
v_max_number := v_max_number + 1;
:g_max_number := v_max_number ;
END;
create sequence test_s1 increment by 1 start with :g_max_number;
(or start with g_max_number)
however, I got error ORA-01722: invalid number. It looks like I can
not use a varible as start number for sequence.
How can I achieve what I want to do (create a sequence that starts with
a variable which I compute from a table) in Oracle?
Thank you very much for your help.

Hi
Use Dynamic SQL
The following Code should work in Oracle 8i.

DECLARE
v_max_number NUMBER;
stmt Varchar2(2000) := NULL;
begin
SELECT max(DEPTNO) INTO v_max_number FROM TEST;
v_max_number := v_max_number + 1;
stmt := 'create sequence test_s1 increment by 1 start with '| |to_char(v_max_number);
execute immediate stmt;
end;
