To reverse engineer using a create script, choose the File, Import, Reverse Engineer MySQL Create Script... menu item for a model.
Tables, views, routines, routine groups, indexes, keys, and constraints can be imported from an SQL script file. Objects imported using an SQL script can be manipulated within MySQL Workbench the same as other objects.
Select SQL script file: Open a file open
dialog box with the default file type set to an SQL script
file, a file with the extension
File encoding: Defaults to UTF8.
Place imported objects on a diagram: Also create an EER diagram in MySQL Workbench.
Importing a large number (about 300+) objects could fail to create an EER diagram and instead emit a resource warning with the text "Too many objects are selected for auto placement. Select fewer elements to create the EER diagram." In this case, execute the reverse engineering wizard with this option disabled, manually create the EER diagram, and then import the 300+ objects using the EER diagram catalog viewer.
If your script creates a database, MySQL Workbench creates a new
physical schemata tab on the
MySQL Model page.
Click Execute to reverse engineer the SQL script, verify its results, and optionally place the objects in a new EER diagram.
Click Next to view a summary of the results, and then Finish to close the wizard.
Before exiting MySQL Workbench, be sure to save the schema. Choose the
File, Save menu item
and the reverse-engineered database will be saved as a MySQL
Workbench file with the extension

You can create a data definition (DDL) script by executing the
--no-data option ensures that the
script contains only DDL statements. However, if you are working
with a script that also contains DML statements you need not
remove them; they will be ignored.
If you plan to redesign a database within MySQL Workbench and then
export the changes, be sure to retain a copy of the original DDL
script. You will need the original script to create an
ALTER script. For more information, see

schema or, if there is no schema, a new unnamed schema is created.
