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 NAME
.Nm osql
.Nd utility to test FreeTDS connections and queries
.\"
.Sh SYNOPSIS
.Pp
.Nm
.Fl S Ar dsn 
.Fl U Ar username
.Fl P Ar password
.Op Fl I Pa ini_directory
.\"
.Sh DESCRIPTION
.Pp
.Nm
is a diagnostic tool provided as part of FreeTDS. It is a
Bourne shell script that checks and reports on your configuration
files. If everything checks out OK, it invokes isql.
.Pp
.Nm
works only with the isql that comes with unixODBC.
.\"
.Sh OPTIONS
.Bl -tag -width indent
.It Fl S Ar dsn
the Data Source Name to which to connect, as known to 
.Pa odbc.ini Ns .
.It Fl U Ar username
database
login name.
.It Fl P Ar password
database password.
.It Fl I Ar ini_dir
override
.Pa odbc.ini
file location.
.El
.\"
.Sh EXAMPLE
If you have an
.Pa odbc.ini
with a section like this:
.Bd -literal -offset indent
.Bq myDSN
servername = myserver
TDS_Version = 5.0
.Ed
.Pp
You would invoke 
.Nm
as:
.Pp
.Li osql -S myDSN 
.Op .\|.\|.\&
.\"
.Sh FILES
.Pa odbc.ini
.Pa freetds.conf
.\"
.Sh NOTES
If you can connect with
.Ql osql -S servername -U user -P passwd Ns ,
your FreeTDS ODBC installation is working.
.Pp
.Nm
guesses where unixODBC might look for its
.Pa odbc.ini
by examining the binary. This is not always an effective approach. If
it doesn't work, you'll receive a report of candidate strings. Kindly
pass along the output to help improve the guessing.  
.Pp
If
.Nm
cannot intuit your
.Pa odbc.ini
directory, you can force the issue with
the 
.Fl I
option. However, you're then instructing 
.Nm
what to test, not where unixODBC will eventually look. Your override
is therefore only as good as you are. Look carefully at the error
output before overriding.  
.Pp
If you have suggestions for ways to make
.Nm
more useful as a diagnostic tool, please post them to the FreeTDS
mailing list.
.\"
.Sh HISTORY
.Nm
first appeared in FreeTDS 0.65.
.\"
.Sh AUTHORS
The 
.Nm
utility was written by 
.An James K. Lowden Ns .
