Reverse Engineering

Available Data Providers are:

  • Connection via ADO and DAO

Connection via ADO and DAO:



Select the Linked Table checkbox and fill out the following boxes (name: filled_value):

Link Datasource: C:\Documents and Settings\mario\Documents\MSAccess\fileaccess.mdb

Link Provider String: Microsoft Access;PWD=mypassword

Remote Table Name: TableName



Select the AutoNumber LI data type to display the Auto Number Type box. From this box, you can select Increment or Random.

Select the Byte, Currency, Decimal, Double, Integer, Long Integer, Single data type to display the Number of Decimal Places box.

Select the Hyperlink, Memo, Text data type to display the Allow Zero Length and Compress Unicode checkboxes.


User Data Types in the Model menu

Microsoft Access database does not have user data types. Nevertheless, these user data types in Toad Data Modeler  work only as an additional structure that can be used for a data type that Microsoft Access database supports but that is not available in Toad Data Modeler.

Generation of names in brackets

  • Check Delimited Identifiers in DDL Script Generation | Detail Settings to generate all names in brackets
  • If unchecked, names will be generated without brackets with exception of names that include spaces

Generation of captions

  • Check Generate Captions in DDL Script Generation | Detail Settings for MS Access models

Script Generating

Toad Data Modeler doesn’t generate an SQL script for the Microsoft Access database, but does generate a fully functional source code in the VBA language. The source code can be executed directly in the Microsoft Access as Module. Appropriate libraries in Microsoft Access are necessary - "Microsoft ActiveX Data Objects 2.x Library" and "Microsoft ADO Ext. 2.x for DDL and Security" for ADO, or "Microsoft DAO 3.6 Object Library" for DAO.

To select a suitable library, click the Tools menu | References (in Microsoft Access main menu).

In the beginning of every script generated for Microsoft Access, you will see the following order:
