Dynamic sql versus static sql in a loop

Question

I have a loop that loops around 10 million times.Inside the loop I have a insert statement . To build this insert statement wondering if a) I should use Dynamic sql using bind variables or b) static sql.
I am aware that static sql is always faster than dynamic sql(using bind variable)....but wanted to get some opinion
Please help.

Answer 1

mmm some solution could be to write the same insert with decode/case statement and put there the conditions that you want.
maybe something like this:
SQL> ed
Wrote file afiedt.buf
  1  begin
  2    for i in 1..10 loop
  3      insert into t1 (col1,col2,col3)
  4        values (i,
  5                decode (mod (i,2),0,i,null),
  6                decode (mod (i,3),0,i,null));
  7    end loop;
  8* end;
SQL> /
PL/SQL procedure successfully completed.
SQL> select * from t1;
      COL1       COL2       COL3
         1
         2          2
         3                     3
         4          4
         5
         6          6          6
         7
         8          8
         9                     9
        10         10
10 rows selected.
SQL> truncate table t1;
Table truncated.
SQL> insert into t1 (col1,col2,col3)
  2    select rownum,
  3           decode (mod (rownum,2),0,rownum,null),
  4           decode (mod (rownum,3),0,rownum,null)
  5    from dual
  6  connect by rownum <=10;
10 rows created.
SQL> select * from t1;
      COL1       COL2       COL3
         1
         2          2
         3                     3
         4          4
         5
         6          6          6
         7
         8          8
         9                     9
        10         10
10 rows selected.forgot that you are not using anymore the loop :)
