= `@SqlMergeMode`

`@SqlMergeMode` is used to annotate a test class or test method to configure whether
method-level `@Sql` declarations are merged with class-level `@Sql` declarations. If
`@SqlMergeMode` is not declared on a test class or test method, the `OVERRIDE` merge mode
will be used by default. With the `OVERRIDE` mode, method-level `@Sql` declarations will
effectively override class-level `@Sql` declarations.

Note that a method-level `@SqlMergeMode` declaration overrides a class-level declaration.

The following example shows how to use `@SqlMergeMode` at the class level.
