Hi,
SQLGetData expects the buffer length parameter to be a SQLLEN variable, which is a signed type.
SQL_NULL_DATA is defined as -1, which is 4294967295 if you interpret it as an unsigned type.
Your my_buff_len variable is being set to SQL_NULL_DATA correctly, but you are looking at it wrong.
Change it to be the correct type, and it will work as you expect.

Harun
Thanks for the reply.
my_buff_len is defined as SQLLEN
SQLLEN my_buff_len;
SQLGetData(my_stmt, my_col_no, SQL_C_CHAR, &my_max_len, 0, &my_buff_len)
if (my_buff_len == SQL_NULL_DATA)
{
{
// Doesn't come here
}
What is being missed above?
Regards...
