Using bsqlodbc, I get an error for the following query.  I think it's
related to conversion of a TIMESTAMP datatype.  We seem to be losing a
byte somewhere.  I'm not sure where the error is.  

bsqldb output is OK.  The problem appears to be in the ODBC layer or
perhaps between keyboard and chair.  

Results follow.  

--jkl


bsqldb output:

Query:

$ cat test/datetime.sql
use FreeTDS
go

create table at( i int, ts timestamp, sd smalldatetime, d datetime )
go
insert at (i, sd, d) values (42, getdate(), getdate())
select * from at
drop table at
go
