## Name

&&& — 如果 A 的 n 维边界框与 B 的 n 维边界框相交，则返回 `TRUE`

## Synopsis

`boolean &&&(` geometry A , geometry B `)`;

## 描述

`&&&`运算符返回`TRUE`，如果 A 的 n 维边界框与 B 的 n 维边界框相交。

 该操作符将利用几何上可能可用的任何索引。

## 示例：3D线串

```SELECT tbl1.column1, tbl2.column1, tbl1.column2 &&& tbl2.column2 AS overlaps_3d,
tbl1.column2 && tbl2.column2 AS overlaps_2d
FROM ( VALUES
(1, 'LINESTRING Z(0 0 1, 3 3 2)'::geometry),
(2, 'LINESTRING Z(1 2 0, 0 5 -1)'::geometry)) AS tbl1,
( VALUES
(3, 'LINESTRING Z(1 2 1, 4 6 1)'::geometry)) AS tbl2;

column1 | column1 | overlaps_3d | overlaps_2d
---------+---------+-------------+-------------
1 |       3 | t           | t
2 |       3 | f           | t

```

## 示例：XYM线串

```SELECT tbl1.column1, tbl2.column1, tbl1.column2 &&& tbl2.column2 AS overlaps_3zm,
tbl1.column2 && tbl2.column2 AS overlaps_2d
FROM ( VALUES
(1, 'LINESTRING M(0 0 1, 3 3 2)'::geometry),
(2, 'LINESTRING M(1 2 0, 0 5 -1)'::geometry)) AS tbl1,
( VALUES
(3, 'LINESTRING M(1 2 1, 4 6 1)'::geometry)) AS tbl2;

column1 | column1 | overlaps_3zm | overlaps_2d
---------+---------+-------------+-------------
1 |       3 | t           | t
2 |       3 | f           | t
