extends Object
implements BindMarkers
Class Inheritance
All Implemented Interfaces
org.springframework.r2dbc.core.binding.BindMarkers
Imports
java.util.concurrent.atomic.AtomicIntegerFieldUpdater
Anonymous, index-based bind marker using a static placeholder. Instances are bound by the ordinal position ordered by the appearance of the placeholder. This implementation creates indexed bind markers using an anonymous placeholder that correlates with an index.

Note

Anonymous bind markers are problematic because they have to appear in generated SQL in the same order they get generated. This might cause challenges in the future with complex generate statements. For example those containing subselects which limit the freedom of arranging bind markers.
