Script Config Files

It’s possible to configure SQL migrations on a per-script basis.

This is achieved by creating a script configuration file in the same folder as the migration. The script configuration file name must match the migration file name, with the .conf suffix added. Script configuration files do not need to be explicitly listed in the main configuration, or the command line.

For example, a migration file sql/V2__my_script.sql would have a script configuration file sql/V2__my_script.sql.conf.

Script Config Files have a subset of the options from the other ways of configuring Flyway (e.g. flyway.conf). See the Reference at the bottom of the page for the complete list of options.


Script config files have the following structure:

# Settings are simple key-value pairs


# Encoding of this SQL migration. Caution: changing the encoding after this migration has been run
# will invalidate the calculated checksum and require a `flyway repair`.

# Manually determine whether or not to execute this migration in a transaction. This is useful for
# databases like PostgreSQL and SQL Server where certain statements can only execute outside a transaction.

# Whether this SQL migration should have its Flyway placeholders replaced. This behaves exactly like the global
# 'placeholderReplacement' parameter but applies only to this script. Default: true

# Whether this migration should be executed or ignored. Valid values are 'true', 'false', 'A==B', 'A!=B' (where
# A,B are values), and combinations of these using `&&` (AND), `||` (OR) and parentheses. This
# migration is executed if the boolean expression evaluates to true, ignored if it evaluates to false, and throws an
# exception if the expression is invalid. Placeholder replacement is also supported in the expression.
# Example: 'shouldExecute=(${environment}==dev || ${environment}==test)' will run if '${environment}' is 'dev' or 'test'
