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.
-D
database
- Database to use.
-H
hostname
- hostname Override name of client sent to server.
-P
password
- Database server password.
-S
servername
- Database server to which to connect.
-U
username
- Database server login name. If username is not provided, a domain login is
attempted for TDS 7+ connections.
-e
error_file
- Name of file for errors.
-h
- Print column headers with the data to the same file.
-i
input_file
- Name of script file, containing SQL.
-o
output_file
- Name of output file, holding result data.
-q
- Do not print column metadata, return status, or rowcount. Overrides
-h
.
-t
field_term
- Specifies the field terminator. Default is two spaces (' '). Recognized
escape sequences are tab ('\t'), carriage return ('\r'), newline ('\n'),
and backslash ('\\').
-v
- Verbose mode, for more information about the DB-Library 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.
-R
pivot_description
- Specify pivot trasformation. The format is
⟨down columns⟩
⟨across columns⟩
⟨function⟩
⟨value⟩. Columns are specified but
numbers. The format of down columns and
across columns is a comma separated list of columns.
function is either count, sum, min or max.
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.
The bsqldb
utility was written by James
K. Lowden ⟨jklowden@freetds.org⟩.
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.
