Hi,
I see what you mean and I tried it. What I did is I tried to coerce the varchar datatype to STRING, by using the following statement:

/* Coerce select-list value to STRING */

select_des->T[i] = 5;

But the length returned is still the maximum length of the varchar field.

I also tried to set the T array of datatype codes to tell Oracle the external datatype of each bind variable ( Oracle is supposed to do any necessary conversion between external and internal datatypes at OPEN time, by using the following statement :

bind_des->T[i] = 5;

But it doesn't work.

Thank you for your help.
