Should Execute

Flyway Teams

Description

shouldExecute is a script configuration option that lets you define when a migration should execute. Unlike skipExecutingMigrations, this will not update the schema history table.

Usage

In order to use this option, you first have to create a script configuration file which defines the conditions under which the script should be executed. This file contains the options for this migration script

Configuration File

shouldExecute=<expression>

Where expression evaluates to a boolean value

• Either true or false
• <A>==<B> or <A>!=<B> where <A> and <B> are placeholders or literal values.
• Combinations of these using && (AND), || (OR) and parentheses ( )

Flyway will change behavior for this migration depending on the expression evaluation:

• If it evaluates to true, this migration is executed
• If it evaluates to false, this migration is ignored
• If it fails to evaluate, an exception will be thrown

The power of this configuration comes from their integration with placeholders that allow you to set the condition for a specific script and control that condition globally.
