mdb-sql
MDBTools(1)MDBTools(1)NAME
mdb-sql - SQL interface to MDB Tools
SYNOPSIS
mdb-sql [-HFp] [-d delimiter] [-i file] [-o file] [database]
DESCRIPTION
mdb-sql is a utility program distributed with MDB Tools.
mdb-sql allows querying of an MDB database using a limited SQL subset language.
OPTIONS -H Supress header row.
-F Supress footer row.
-p Turn off pretty printing. By default results are printed in an ascii table format which looks nice but is not conducive to manipu-
lating the output with unix tools. This option prints output plainly in a tab separated format.
-d Specify an alternative column delimiter. If no delimiter is specified, columns will be delimited by a tab character if pretty print-
ing (-p) is turned off. If pretty printing is enabled this option is meaningless.
-i Specify an input file. This option allows an input file containing the SQL to be passed to mdb-sql. See Notes.
-o Specify an output file. This option allows the name of an output file to be used instead of stdout.
COMMANDS
mdb-sql in interactive mode takes some special commands.
connect to <database>
If no database was specified on the command line this command is necessary before any querys are issued. It also allows the switch-
ing of databases once in the tool.
disconnect
Will disconnect from the current database.
go Each batch is sent to the parser using the 'go' command.
reset A batch can be cleared using the 'reset' command.
list tables
The list tables command will display a list of available tables in this database, similar to the mdb-tables utility on the command
line.
describe table <table>
Will display the column information for the specified table.
quit Will exit the tool.
SQL LANGUAGE
The currently implemented SQL subset is quite small, supporting only single table queries, no aggregates, and limited support for WHERE
clauses. Here is a brief synopsis of the supported language.
select:
SELECT [* | <column list>] FROM <table> WHERE <where clause>
column list:
<column> [, <column list>]
where clause:
<column> <operator> <literal> [AND <where clause>]
operator:
=, =>, =<, <>, like, <, >
literal:
integers, floating point numbers, or string literal in single quotes
NOTES
When passing a file (-i) or piping output to mdb-sql the final 'go' is optional. This allow constructs like
echo "Select * from Table1" | mdb-sql mydb.mdb
to work correctly.
The -i command can be passed the string 'stdin' to test entering text as if using a pipe.
ENVIRONMENT
MDB_JET3_CHARSET
Defines the charset of the input JET3 (access 97) file. Default is CP1252. See iconv(1).
MDBICONV
Defines the output charset. Default is UTF-8. mdbtools must have been compiled with iconv.
MDBOPTS
semi-column separated list of options:
o use_index
o no_memo
o debug_like
o debug_write
o debug_usage
o debug_ole
o debug_row
o debug_props
o debug_all is a shortcut for all debug_* options
HISTORY
mdb-sql first appeared in MDB Tools 0.3.

The mdb-sql utility was written by Brian Bruns.
BUGS
The supported SQL syntax is a very limited subset and deficient in several ways.
