public interface Condition extends CqlSnippet
ConditionalStatement
.
To build instances of this type, use the factory methods, such as column
, field(String, String)
field}, etc.
They are used as arguments to the ConditionalStatement.if_(Iterable)
method, for
example:
deleteFrom("foo").whereColumn("k").isEqualTo(bindMarker())
.if_(Condition.column("v").isEqualTo(literal(1)))
// DELETE FROM foo WHERE k=? IF v=1
There are also shortcuts in the fluent API when you build a statement, for example:
deleteFrom("foo").whereColumn("k").isEqualTo(bindMarker())
.ifColumn("v").isEqualTo(literal(1))
// DELETE FROM foo WHERE k=? IF v=1
