'select count...' returns SQL_VARCHAR?

Hello everyone,

I am using the PostgreSQL and its ODBC driver but there seems to be
some problem with the "select count(...)..." queries. Here is my
configuration:
  - FreeBSD 4.6
  - PostgreSQL 7.2.1
  - PostgreSQL odbc driver 7.2.1
  - Driver Manager: iodbc 3.0.5 (and also tested with unixODBC 2.2.1
  and their pgsql odbc driver)
  - OTL 

In my test case I just want to execute a simple "SELECT COUNT(*) FROM
test_tab" but the result is an OTL exception whenever I try to get the
count as an int. The error message is that the result of the query is
a VARCHAR and so I should use a char[] instead. (Indeed, extracting it
in a C string works and gives the correct result.)

I tried to track the error and I saw that inside the OTL the
SQLDescribeCol function is called for the specific query that returns
12 (SQL_VARCHAR) as the data type of the (single) 'count' column.

So is this a bug, a feature, or something else?
Do I miss something?

Best regards
Stelios Sfakianakis
