mdb-header - Man Page

Write header file from an MDB database


mdb-header [database]


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

It will dump the names and types of the tables and columns in an MDB database in a C header format.

It will create three files - types.h and dumptypes.[ch]



Defines the charset of the input JET3 (access 97) file. Default is CP1252. See iconv(1).


Defines the output charset. Default is UTF-8. mdbtools must have been compiled with iconv.


Colon-separated list of options:

  • debug_like
  • debug_write
  • debug_usage
  • debug_ole
  • debug_row
  • debug_props
  • debug_all is a shortcut for all debug_* options
  • no_memo (deprecated; has no effect)
  • use_index (experimental; requires libmswstr)

Exit Status

mdb-header exits with error code 1 if there was anunsupported type.

Future Directions

mdb-header is deprecated. Soon, it will no longer be distributed.

It is the feeling of developers that it is not used, as C code generation is now usually replaced by more generic approaches, including libmdb calls and odbc.

However, should you find this tool useful, drop us a line at and we'll consider maintaining it.
