bsqldb is a utility program distributed with
FreeTDS.
bsqldb is a non-interactive equivalent
of the "isql" utility programs distributed by Sybase and Microsoft.
Like them,
bsqldb uses the command "go"
on a line by itself as a separator between batches. The last batch need not be
followed by "go".
bsqldb makes use of
the DB-Library API provided by FreeTDS. This API is of course also available
to application developers.

newline ('\n'), and backslash ('\\').
- -v
- Verbose mode, for more information about the DB-Library
interaction. This also reports the result set metadata, including and

-
-R
pivot_description

⟨down columns⟩
⟨across columns⟩
⟨function⟩
⟨value⟩. Columns are
specified but numbers. The format of down

DSQUERY default
servername
bsqldb is a filter; it reads from standard input,
writes to standard output, and writes errors to standard error. The
-i,
-o, and
-e options override these defaults.
The source code for
bsqldb is intended as a model
for DB-Library users. DB-Library has a rich set of functions, and it can be
hard sometimes to understand how to use them, particularly the first time. If
you find something about the source code unclear, you are encouraged to email
the author your comments.
bsqldb exits 0 on success, and >0 if the server
cannot process the query.
For messages with severity > 10,
bsqldb calls
exit(3) with the severity level. For example, if the severity level is 16,
bsqldb will return an exit status of 16 to the
shell.
bsqldb first appeared in FreeTDS 0.63.

Microsoft servers as of SQL Server 7.0 SP 3 do not return output parameters
unless the RPC functions are used. This means
bsqldb cannot return output parameters for stored
procedures with these servers.
