推荐答案
您的查询相当大，由于缺少缩进和正常工作的小提琴，很难知道问题出在哪里。有关进一步的问题，请考虑创建minimal reproducible example。我还注意到，在一个查询中，您要转换几何图形18次(！)在31467和25832之间来回。真的有必要吗？请记住，转换可能需要时间，并且肯定会减慢查询速度。如果可能，在函数链的起点或末端进行必要的转换。例如，不是
WITH j (point) AS(
VALUES ('POINT(1 2)'::geometry)
)
SELECT st_astext(
ST_MakeEnvelope(
ST_X(ST_Transform(ST_SetSRID(point,31467),25832)),
ST_Y(ST_Transform(ST_SetSRID(point,31467),25832)),
ST_X(ST_Transform(ST_SetSRID(point,31467),25832))+10,
ST_Y(ST_Transform(ST_SetSRID(point,31467),25832))+10),2)
FROM j;
..考虑一下：
WITH j (point) AS(
VALUES (ST_SetSRID('POINT(1 2)'::geometry,31467))
)
SELECT
ST_Transform(
ST_MakeEnvelope(
ST_X(point),ST_Y(point),ST_X(point)+10,ST_Y(point)+10,31467),
25832)
FROM j
结果可能略有不同，但根据您的用例不会有太大影响。尝试这两种方法，如果可能，请保持代码干净。
话虽如此，您可以使用ST_NumGeometries来计算一列中的几何图形的数量：
SELECT
ST_NumGeometries('MULTIPOLYGON (((40 40, 20 45, 45 30, 40 40)),((20 35, 10 30, 10 10, 30 5, 45 20, 20 35)))'::geometry),
ST_NumGeometries('POLYGON((40 40, 20 45, 45 30, 40 40))'::geometry);
st_numgeometries | st_numgeometries
------------------+------------------
2 | 1
因此您的查询应该如下所示：
WITH j AS (
SELECT DISTINCT
ST_MakeEnvelope(
ST_X(ST_Transform(ST_SetSRID(point,31467),25832)),
ST_Y(ST_Transform(ST_SetSRID(point,31467),25832)),
