Convert MWB to SQL

A MySQL Workbench model must be exported when a MySQL server, deployment process, migration tool, or administrator requires executable SQL instead of an editable design file. The resulting script can be shared, reviewed, version-controlled, or run against a compatible database.

What the MWB format is

.mwb is the native model format used by MySQL Workbench. It stores a visual database design, including tables, columns, data types, keys, relationships, views, routines, and diagram layout. MWB files are used to share EER diagrams, maintain schemas before deployment, and preserve versioned database designs. An MWB file is not a SQL dump and cannot be executed directly by MySQL.

What the SQL format is

SQL is a language, not one universal file structure. A generated .sql file normally contains MySQL-oriented DDL statements such as CREATE DATABASE, CREATE TABLE, index definitions, foreign keys, views, and routines. SQL can deploy the model to a MySQL server, support schema review and migration workflows, and provide a readable representation for version control. The target MySQL version and dialect affect syntax, storage-engine clauses, character sets, collations, and compatibility.

How to convert MWB to SQL

Use the official desktop MySQL Workbench application because MWB is its native format.

1. Install a MySQL Workbench release compatible with the model, then open it.
2. Select File → Open Model and choose the .mwb file.
3. Inspect the model for unresolved objects, missing foreign-key references, unsupported data types, duplicate names, and incorrect relationships.
4. Select File → Export → Forward Engineer SQL CREATE Script. Depending on the Workbench release, the same command may appear among the model's forward-engineering commands.
5. Choose an output path such as schema.sql. Enable only the required options, including schema or database creation, table definitions, indexes, foreign keys, views, routines, and drop statements.
6. Open the generated script in a code editor. Check the database name, object order, identifier quoting, storage engines, character sets, collations, foreign-key actions, and syntax supported by the target server.

Test the script with the MySQL client after creating or selecting the destination database:

mysql -u username -p database_name < schema.sql

This command executes an existing SQL file; it does not convert an MWB file. To create the database directly from Workbench, use Database → Forward Engineer, select a server connection, review the generated statements, and run them. To compare an existing server with the model, use Workbench reverse engineering or schema synchronization rather than exporting the model without comparison.

Quality and compatibility limitations

The export is normally a schema conversion, not a data conversion. It does not copy table rows, server users, privileges, server settings, or other server-level configuration. Diagram positions and other Workbench design metadata have no SQL equivalent. Triggers, events, routines, and views are included only when they are represented in the model and supported by the selected Workbench version and export options.

Run the script first against the same MySQL major version targeted by the model, or against a tested compatible version. Review reserved words, generated columns, spatial types, foreign-key creation order, default expressions, storage engines, character-set and collation defaults, and version-specific syntax. A model intended for MariaDB, an older MySQL release, or another database system may require manual rewriting because Workbench generates MySQL-oriented SQL rather than database-neutral SQL.

There is no generally reliable online MWB-to-SQL converter comparable to Workbench's native export. Generic file-conversion websites usually do not understand the Workbench model structure, and uploading a schema can expose proprietary database information. Keep the original MWB file as the editable source and use MySQL Workbench locally for conversion.
