Thanks for the kind words. It seems I must have missed something as datacopy is working for me when copying DATE and TIME columns from ASE 15.7 to ASE 15.7.

A lot of what I did was trial and error and I tried to remember to leave a comment so I could find what I'd changed in order to write it up at the end.

Any idea which file I would have changed to get it working with dblib? If not I'll untar the package somewhere else and run a find and diff to see if I can spot it.

Cheers,

Matthew.

Dear All,

I'm not really a C programmer (or C++ for that matter) but I wanted to be
able to use datacopy to copy tables with DATE and TIME data types. So, I
decided to have a crack at adding them to FreeTDS.

My testing has been successful, although I'm not sure the way I've coded it
is correct so any help/fixes would be appreciated.

I've attached a rich text document with the details. The first part proposes a quick
and dirty fix, while the second is my best guess at the "correct" way of
doing things.

Bare in mind that this is currently only for Sybase to Sybase. I'm going to
look at doing this for SQL Server too but that's a bit more complicated!

Cheers,

Matthew.


Patch and effort are really appreciated.
So appreciated that I already pushed some changes and is actually
testing deeply (but I don't think there will be any regression).

datacopy still does not work as SYBDATE/SYBTIME are not supported by
dblib (you added support for libTDS not upper libraries and datacopy
is based on dblib).

Currently converting from string will use datetime format in all
cases. ODBC has its standard so format strings are well defined for
it.

I added some improvements too based on previously patches on some other types.

Yes, adding a new type in FreeTDS is really a nightmare !!!
