Forgeting about Clipper (dbase) limitations, would the TIMESTAMP
datatype still enable me to:
(i) Search between date ranges (no time values specified)
(ii) Search between time values (no date values specified)
(iii) Search on date and time ranges
(iv) Load the TIMESTAMP with a value of
DateValue + nill
because we have many files with dates, and no times
Any other limitations we would experince going from seperate DATE,
TIME columns to a TIMESTAMP ?
I have dropped the DATE , TIME columns , added the TIMESTAMP and
with the (www.clevercomponents.com) datapump, loaded a Dbase
CHAR datatype to the TIMESTAMP datatype.
Guess what, ........ now there are no errors. Thanks !! :)

Will check that out, thanks

Yes, fortunately, I haven't had much exposure at all to the BDE, and the
"pre-purchase" D6 months, I spent reading thru the
Borland.public.delphi... and borland.public.interbase... ng's, also the
...bde newsgroup. After a few months of that, I was convinced not to go
anywhere near the BDE.
Thanks,
