Little problem.............two days trying to find the error

Question

hey people, I am trying to get two values of two different tables, at put it in one that link both of them, I already have it working, but I am trying to make it simpler and smaller.
create or replace procedure baba
var_a number,
var_b varchar2
AS
BEGIN
insert into bebe ( c, d)
select (c, d from table_c, table_d where table_c.a = var_a and table_d.b = var_b);
END;
I am trying to make two select within one and the insert the value directly to the third table. three days on this.
When I compile it gives me the error that misses one bracket, weird.
Thanks.

Welcome to OTN. ;)
Always mention your DB version.
Now, regarding your question - why do you need to implement this using Procedure when a single DML will suffice?
Always, ask yourself about whether you should implement it using SQL or PL/SQL.
In general, try to achieve using SQL. If you can't then only go for PL/SQL.
Now,
create or replace procedure baba
var_a number,
var_b varchar2
AS
BEGIN
insert into bebe ( c, d)
select c, d
from table_c, table_d
where table_c.a = var_a
and table_d.b = var_b;
END;So, those braces i've removed.
It should work.
N.B.: Not Tested...

Added: Also you need to use join condition between the two table - otherwise it will produce curtesian product. ;)
