晋太元中，武陵人捕鱼为业。缘溪行，忘路之远近。忽逢桃花林，夹岸数百步，中无杂树，芳草鲜美，落英缤纷。渔人甚异之，复前行，欲穷其林。 　　林尽水源，便得一山，山有小口，仿佛若有光。便舍船，从口入。初极狭，才通人。复行数十步，豁然开朗。土地平旷，屋舍俨然，有良田、美池、桑竹之属。阡陌交通，鸡犬相闻。其中往来种作，男女衣着，悉如外人。黄发垂髫，并怡然自乐。 　　见渔人，乃大惊，问所从来。具答之。便要还家，设酒杀鸡作食。村中闻有此人，咸来问讯。自云先世避秦时乱，率妻子邑人来此绝境，不复出焉，遂与外人间隔。问今是何世，乃不知有汉，无论魏晋。此人一一为具言所闻，皆叹惋。余人各复延至其家，皆出酒食。停数日，辞去。此中人语云：“不足为外人道也。”(间隔 一作：隔绝) 　　既出，得其船，便扶向路，处处志之。及郡下，诣太守，说如此。太守即遣人随其往，寻向所志，遂迷，不复得路。 　　南阳刘子骥，高尚士也，闻之，欣然规往。未果，寻病终。后遂无问津者。 .

.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
database to use. Optional if the procedure/view being extracted is in your
default database.
.It Fl i Ar input_file
a script to apply to the database. Not currently implemented.
.It Fl o Ar output_file
a file to hold the script, defaults to standard output.
.It Fl v
Show version information and copyright notice.
.El
.\"
.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.
