NAME¶
bsqldb - batch SQL script processor using DB-Library
SYNOPSIS¶
bsqldb [-U username] [-P password] [-S servername] [-D database]
[ -i input_file] [-o output_file] [-e error_file] [-H hostname]
[ -t field_term] [-hqv]
DESCRIPTION¶
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.
OPTIONS¶
- -U username
- Database server login name. If username is not
provided, a domain login is attempted for TDS 7+ connections.
- -P password
- Database server password.
-S servername Database server to which to connect.
- -D database
- Database to use.
- -i input_file
- Name of script file, containing SQL.
- -o output_file
- Name of output file, holding result data.
- -e error_file
- Name of file for errors.
- -t field_term
- Specifies the field terminator. Default is two spaces ('
'). Recognized escape sequences are tab ('\t'), carriage return ('\r'),
newline ('\n'), and backslash ('\\').
- -h
- Print column headers with the data to the same file.
- -H
- hostname Override name of client sent to
server.
- -q
- Do not print column metadata, return status, or rowcount.
Overrides -h.
- -v
- Verbose mode, for more information about the DB-Libraryrary
interaction. This also reports the result set metadata, including and
return code. All verbose data are written to standard error (or
-e), so as not to interfere with the data stream.
ENVIRONMENT¶
- DSQUERY
- default servername
NOTES¶
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, of course.
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 are using it
in this way and find something unclear, you are encouraged to email the author
your comments.
EXIT STATUS¶
bsqldb exits 0 on success, and >0 if the server cannot process the
query.
bsqldb will report any errors returned by the server, but will continue
processing. In a production environment, this behavior may be insufficiently
stringent. To make it extremely intolerant of errors, change the message and
error handlers to call
exit(3).
HISTORY¶
bsqldb first appeared in FreeTDS 0.63.

BUGS¶
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.
