       mdb-schema - Generate schema creation DDL

SYNOPSIS

       mdb-schema [options] [-T tablename] [-N prefix] database [backend]
       mdb-schema -h|--help
       mdb-schema --version

DESCRIPTION

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

       It  produces  DDL  (data  definition  language) output for the given database. This can be
       passed to another database to create a replica of the original access table format.

OPTIONS

       -T, --table tablename
              Single table option.  Create schema for this table only. Default is to  export  all
              tables.

       -N, --namespace prefix
              Prefix identifiers with namespace.

       --drop-table
              Issue DROP TABLE statement.

       --no-drop-table
              Don't issue DROP TABLE statement. This is the default.

       --not-null
              Issue NOT NULL constraints. This is the default.

       --no-not-null
              Don't issue NOT NULL constraints.

       --default-values
              Issue DEFAULT values.

       --no-default-values
              Don't issue DEFAULT values. This is the default.

       --not-empty
              Issue CHECK <> '' constraints.

       --no-not-empty
              Don't issue CHECK <> '' constraints. This is the default.

       --comments
              Issue  COMMENT  ON  statements with column/table descriptions. This is the default,
              but it's not supported by all backends.

       --no-comments
              Don't issue COMMENT ON statements.

       --indexes
              Export INDEXes. This is the default.

       --no-indexes
              Don't export INDEXes.

       --relations
              Export foreign keys constraints. This is the default.

       --no-relations
              Don't export foreign keys constraints.

       --version
              Print the mdbtools version and exit.

       backend
              Specifies  target  DDL  dialect.  Supported  values  are  access,  sybase,  oracle,
              postgres,  mysql  and  sqlite. If not specified the generated DDL will be in access
              format.

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 to use for the SQL file. Default is UTF-8. mdbtools must
              have been compiled with iconv.

       MDBOPTS
              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)

BUGS

       Relationships  and other features may not be supported by all databases.  Access datatypes
       are mapped to their closest counterparts in the target backend. This may not always  yield
       an exact fit.
