Hello again,
Also, since 'isql help' command is working, we know then that the
ODBC API is being referenced 'ok' since 'help' uses the SQL Columns and
SQLTables API calls. It appears that when a SELECT is done, the SQLPrepare
ODBC API call is failing maybe due to not know how to handle the rows
returned. I tried a SELECT which returns 1 row, 1 column and I still get the
error SQLRowCount returns -1.

Hi Frediano,
I am certain I am connecting to the correct database. But check out
this feedback I got from an unixODBC mailing list:

"-1 from a SQLRowCount is entirly ok, it just means that the driver does not
know how many rows are in the result set which is common with forward only
cursors. Beyond that, I don't know what to suggest, I can only assume its a
driver problem."

Assuming this is true, is there some parameter that needs to be set
to tell it a buffer or textsize required to get the data returned to the
screen?
Please advise and thanks for your help.

It's possible that you are in the wrong database? Or that you don't have
permission for some columns/rows ?
