NAME

mdb-schema - Generate schema creation DDL

SYNOPSIS

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

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.

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.
