Size (in Bytes) of data in response.

Question

Hi;
Is there a quick way of getting the size (length of data) in the response?
The api, as I see it, only has a reponse.getBufferSize. I need something like string.length().
Thank you much.

Use the good old "let's put my hands on this" approach:TEST> create table test_number
  2  (
  3  a number(1),
  4  b number(2),
  5  c number(3),
  6  d number(38)
  7  );
Table created.
TEST> insert into test_number
  2  values
  3  (1,11,111,to_number(rpad('9',38,'9')));
1 row created.
TEST> insert into test_number
  2  values
  3  (1,1,11,to_number(rpad('9',15,'9')));
1 row created.
TEST> COMMIT;
Commit complete.
TEST> select vsize(A),vsize(B),vsize(C), vsize(D) from test_number;
  VSIZE(A)   VSIZE(B)   VSIZE(C)   VSIZE(D)
         2          2          3         20
         2          2          2          9
TEST> truncate table test_number;
Table truncated.
TEST> alter table test_number modify (D NUMBER(38,5));
Table altered.
TEST> insert into test_number
  2  values
  3  (1,11,111,to_number(rpad('9',33,'9')));
1 row created.
TEST> insert into test_number
  2  values
  3  (1,11,111,to_number(rpad('9',33,'9') || ',99'));
1 row created.
TEST> insert into test_number
  2  values
  3  (1,11,111,to_number(rpad('9',33,'9') || ',99999'));
1 row created.
TEST> COMMIT;
Commit complete.
TEST> select vsize(A),vsize(B),vsize(C), vsize(D) from test_number;
  VSIZE(A)   VSIZE(B)   VSIZE(C)   VSIZE(D)
         2          2          3         18
         2          2          3         19
         2          2          3         21Yoann.
