HI, everyone!
In OCI program,
I want to get the number field value of a table just the same as select it
in sqlplus.

e.g.
SELECT * FROM ttt;
SQL> select * from ttt

ID F
---------- ----------
1 1.1234
2 1.1234
3 1.1234
4 1.34421
1748 2.3424
34444 234.3
1.1111E+38 4
1.1000E+34 5
3.4123E+49 5747

But, in my OCI program, when defined with SQLT_STR,
never get the above value, just like:
1 1.1234
2 1.1234
3 1.1234
4 1.34421
1748 2.3424
34444 234.3
111111111111111111111111111111111111111 4
11000000000000000000000000000000000 5
3412341413214240000000000000000000000000000 5747

How to implement like the sqlplus???
