Create ER diagram from sql file in mysql Workbench

Question

I am using tank_auth library for authentication in Codeigniter. I want to draw ER-diagram for tank_auth sql file.

When I imported sql file (reverse engineering) in mysql workbench it shows all table without any relationship between tables (users, user_profiles, user_autologin, login_attempts, ci_sessions ).

how could I get Er-diagram from given sql file ?

Answer 1

MySQL Workbench derives relationships in diagrams from existing foreign keys. If your tables use engines that don't support foreign keys no relationships can be derived automatically.

Answer 2

• Go to to "Database" Menu option
• Select the "Reverse Engineer" option.
• A wizard will be open and it will ask for db configuration/source
• On finish it will generate the ER Diagram for you
