.Sh DESCRIPTION
.Pp
.Nm
is a utility program distributed with FreeTDS. It replaces
a similar program of the same name distributed by Sybase.
.Pp
.Nm
reads the text of a stored procedure or view, and writes a script
suitable for recreating the procedure or view. For tables, it reads
the output of sp_help and constructs a
.Ql CREATE TABLE
statement, complete
with
.Ql CREATE INDEX Ns ,
too.
.\"
.Ar owner
is optional if you or the database owner is the owner
of the procedure/view being copied.
.Ar object_name
is the name of the system object you wish to extract.
.\"
.Sh OPTIONS
.Bl -tag -width indent
.It Fl U Ar username
database server login name.
.It Fl P Ar password
database server password.
.It Fl S Ar server
database server to which to connect.
.It Fl D Ar database

default database.

.Sh NOTES
.Nm
is a filter; it reads from standard input, writes to standard output,
and writes errors to standard error. The
.Fl i ,
.Fl o ,
and
.Fl e
options override these defaults.
.Pp
.Nm
makes use of the db-lib API provided by FreeTDS. This
API is of course also available to application developers.
.Sh EXIT STATUS
.Pp
.Nm
exits 0 on success, and >0 if the server cannot process the query.
.Pp
.Nm
will report any errors returned by the server, but will continue
processing.
.\"
.Sh HISTORY
.Pp
.Nm
first appeared in FreeTDS 0.63.

.Sh AUTHORS
The
.Nm
utility was written by
.An James K. Lowden Aq jklowden@schemamania.org.
.\"
.Sh BUGS
Works only with Microsoft servers and ancient Sybase servers.
Does not create primary keys.
Many options are defined by Sybase that this version does not implement. Feel
free to correct this situation.
In theory,
.Nm
could apply/produce DDL for any system object,
but at present only tables, procedures and views are supported,
and only for extraction.
