Description

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.

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

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.
