Question

I am trying to follow this guide for creating pl/sql blocks and I am getting an ORA-00922:missing or invalid option on the SET orderNumberSEQ.... What am I doing wrong?

declare
orderNumberSEQ number(5);
userid varchar(20);

begin
insert into bs_orders (userid, ono, timepurchased)
values('lilith', orderNum_seq.NEXTVAL,(SELECT current_timestamp FROM dual));

SET orderNumberSEQ := orderNum_seq.CURRVAL;

SELECT userid FROM bs_orders
where ono = orderNumberSEQ;
end;
/

You don’t need to use SET. Just

SELECT orderNum_seq.CURRVAL INTO orderNumberSEQ FROM DUAL;

will do the trick. Or if you use oracle11:

orderNumberSEQ := orderNum_seq.CURRVAL;
