To reverse engineer using a create script, choose the, , 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.Note
Importing a large number (1000) 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 1000+ 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.

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
