Well done.  Thank you for that problem report.  

The error is somewhere in db-lib.  sqsh (which uses ct-lib) does fine.  

I have reproduced the error with this script:

<snip>
#! /bin/sh
PWD=${HOME}/projects/freetds.cvs/freetds/build/PWD
BSQLDB=/usr/local/bin/bsqldb

DROP="          drop   proc testProc"
CREATE="        create proc testProc
                AS
                BEGIN
                create table #test_api([updated_date] datetime, 
                                       [id] int)
                set nocount on
                insert into #test_api values(getDate(), 1)
                insert into #test_api values(getDate(), 2)
                print 'About to call select'
                select updated_date,id from #test_api
                print 'Did the select'
                END"
EXEC='exec testProc'

S=$(grep ^SRV ${PWD} | awk -F'=' '{print $2}')
U=$(grep ^UID ${PWD} | awk -F'=' '{print $2}')
P=$(grep ^PWD ${PWD} | awk -F'=' '{print $2}')
D=$(grep ^DB  ${PWD} | awk -F'=' '{print $2}')

echo ${BSQLDB} -S $S -U $U -P $P -D testdb $@

printf "%s\nGO\n%s\nGO\n%s\n" "${DROP}" "${CREATE}" "${EXEC}" \
| ${BSQLDB} -S $S -U $U -P $P -D testdb $@
</snip>

As you can see from the output below, dbresults() appears not to set up
the resultset metadata.  I haven't yet been able to investigate further.
