Method join_detailed

datafusion/expr/src/logical_plan/builder.rs:1022–1038

Apply a join with on constraint and specified null equality. The behavior is the same as [`join`](Self::join) except that it allows specifying the null equality behavior. The `null_equality` dictates how `null` values are joined.
