Table 5-30 Valid Values for ddl-generation.output-mode

Value Description

Value	Description
`both`	DDL will be generated and written to both the database and a file. If `eclipselink.ddl-generation` is set to `create-tables`, then `eclipselink.create-ddl-jdbc-file-name` is written to `eclipselink.application-location` and executed on the database. If eclipselink.ddl-generation is set to `drop-and-create-tables`, then both `eclipselink.create-ddl-jdbc-file-name` and `eclipselink.drop-ddl-jdbc-file-name` are written to `eclipselink.application-location`, and both SQL files are executed on the database.
`database`	(Default) DDL will be generated and written to the database only.
`sql-script`	DDL will be generated and written to a file only. If `eclipselink.ddl-generation` is set to `create-tables`, then `eclipselink.create-ddl-jdbc-file-name` is written to `eclipselink.application-location`. It is not executed on the database. If `eclipselink.ddl-generation` is set to `drop-and-create-tables`, then both `eclipselink.create-ddl-jdbc-file-name` and eclipselink.drop-ddl-jdbc-file-name are written to `eclipselink.application-location`. Neither are executed on the database.
