mdb-tables

MDBTools(1)															       MDBTools(1)

NAME

       mdb-tables - Get listing of tables in an MDB database

SYNOPSIS

       mdb-tables [-S] [-1 | -d delimiter] database

DESCRIPTION

       mdb-tables is a utility program distributed with MDB Tools.

       It produces a list of tables contained within an MDB database in a format suitable for use in shell scripts.

OPTIONS

       -S     Show system tables. System tables are generally those beginning with 'MSys'

       -1     specifies that the tables should be listed 1 per line.

       -d delimiter
	      specifies an alternative delimiter. If no delimiter is specified, table names will be delimited by a tab character, or by newline if
	      the -1 option was specified.

NOTES

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-tables first appeared in MDB Tools 0.3.

AUTHORS

       The mdb-tables utility was written by Brian Bruns.

BUGS

       Access allows for tables to have spaces embeded in the table name.
	      You must specify a delimiter (-d) if you intend on piping the output of mdb-tables to a program such as awk or cut.
