You can enter sample table records for entities. Split table creation and drop statements into two files. Split table creation statements and foreign key constraint creation statements into two files. Custom DDL can be added before and after the generated DDL for environment initialization and cleanup. You can also add custom description that stats the assumption or the DB configuration required for executing the DDL script (e.g. You can include the date and time of generation, and the author name as comment. (Only available to My SQL, DB2, Oracle, Postgre SQL)įorce the content of the generated DDL to be in upper case.Īpply proper line breaking and indentation to make the content looks prettier.Ĭlick to customize the generated DDL by adding custom comment and/or the DDL to execute before and after the generated DDL. Generate entity and column description as comments of tables and their columns. By using a DDL, you can execute the table create scripts on the production database manually, and to automate the table creation process as part of the database re-initialization routine. Very often, you don't have direct access to the production database during designing/development.
Select the schema for database generation.Ĭheck this option to create tables in the actual DBMS.ĭDL (Data Definition Language) is a syntax for defining data structure.
#MYSQL WORKBENCH ERD UPDATE#
Update Database - query existing object in database, generate create and alter statement depends on object not exists or outdated in database, or do nothing if database is up-to-date.ĭrop and Create Database - generate drop statements first, then generate create statements.ĭrop Database - generate drop statements only. If you select Drop Database, database tables modeled in ERD will all be dropped in database.Ĭreate Database - generate create statements only. For example, if you select Create Database, a new database will be created base on your ERD. The kind of action to perform, which will influence the outcome. The folder to store the generated DDL files. If you have chosen Generate DDL, you can find the DDL file in the folder specified in the Output Path field. If succeed, and if you have chosen Export to database, you will see the database schema be created in the chosen database. Read the next sections for details about those available options.
If you want database to be created automatically based on your ERD, check Export to database. If this is what you want, uncheck Export to database and check Generate DDL. Sometimes, you may want to review and modify the DDL scripts for database creation, instead of having the database be created completely based on your design. Check and/or uncheck Export to database and Generate DDL.Select Create Database for Generate Database.This opens the Database Generation window. Select Tools > DB > Generate Database.
#MYSQL WORKBENCH ERD MANUAL#
Once you have designed your database with ERD, you can generate the actual database from it, or to generate the DDL file for manual database creation.
