Hi, Helen & Alan.

Thanks for the API Guide Reference...

The double-quoted string is what is returning from the
DB. I am not using a where-clause between two dates.
I remember seeing another post that mentioned the
difference between single & double quotes, so I was
sure to check that (you must get annoyed making the
SAME comments day after day!! :).

At this point, I think I have an issue on how I'm
using the ISC_TIMESTAMP and the SQLDA, but I have seen
no examples of what to do so I'm hunting & pecking.

Apparently, there is an issue converting the sqlvar
datatype, but I have no clue what it is.

My query is:
select MAC, StartTime_Stamp, StopTime_Stamp from
Trends

The complete error message returned via
isc_interpret() is (NOTE: 5-MAY-2007 1:00:00.000 is
the StartTime data):
Dynamic SQL Error error code = -303 conversion error
from string \"5-MAY-2007 1:00:00.000\"

The Variables are defined as:
ISC_TIMESTAMP Start, Stop;

And the SQLVAR fields are set up as:
SQLDA1->sqlvar[1].sqldata = (char*)&Start;
SQLDA1->sqlvar[1].sqltype = SQL_TIMESTAMP;
SQLDA1->sqlvar[1].sqllen = sizeof(ISC_TIMESTAMP);

SQLDA1->sqlvar[2].sqldata = (char*)&Stop;
SQLDA1->sqlvar[2].sqltype = SQL_TIMESTAMP;
SQLDA1->sqlvar[2].sqllen = sizeof(ISC_TIMESTAMP);


Again, any help would be appreciated...I'm bumping a
deadline on this...

Kurt.
