Filename Requirements

To ensure proper version control and execution, your SQL migration filenames must follow a specific structure. Each filename consists of three main parts: a Version, a Description, and an optional Change Type Suffix. <Version>_<Description>_<Suffix>.sql

​
Versioning Format

Bytebase supports both semantic versioning and simple timestamp-based versions. The version number is crucial for ordering migrations correctly. The version must begin with a number. A v or V prefix is optional. Valid Version Examples:
  • 202501150900_add_user_table.sql
  • v1.2.3_description.sql
  • V2_add_users_table.sql
  • 1.0_initial_schema.sql

​
Change Type Suffixes

You can add a suffix to the filename to specify the change type. If the suffix is omitted, the file will be treated as the default DDL type. The suffix is added to the end of the filename, just before the .sql extension.
  • DDL (Default)
    • Used for standard schema changes (Data Definition Language). This is the default type used when no suffix is present.
    • Example: v1.0_create_table.sql
  • DML
    • Used for data manipulations (Data Manipulation Language).
    • Add the _dml suffix.
    • Example: v1.0_insert_data_dml.sql
  • Ghost
    • Used for schema changes performed using the gh-ost tool.
    • Add the _ghost suffix.
    • Example: v1.0_alter_table_ghost.sql
