Click the Ok, that is, you can see the newly added options:

Configuration is complete.

Step three: Sql script file for the database export

 

 

Step Four: Open PowerDesigner software, generate a model import

A, select menu, import data source

B. Select Database Version

C. Click Add File Sql

Database Model D. After clicking OK, you can convert to generate the desired

Step five, set up own information:

A, double-click on the table, to enter the edit mode, Note: Remember to add comment tables and columns, as shown below:

Click below button:

B, check the checkbox Comment

C, open the window to execute the script editor

D, VBS script to perform the following:
