如何根据 ST_GeometryType 过滤 postgis 查询
How to filter postgis queries based on ST_GeometryType
我有下面发布的查询。我想在 where 子句中添加以下
AND ST_GeometryType(geom.dump) LIKE "ST_Multipolygon"
我想过滤掉 multipolgon 类型的几何图形
请让我知道我该怎么做
查询

您的查询相当大，并且由于缺少缩进和工作 fiddle 很难知道问题出在哪里。对于进一步的问题，请考虑创建一个 minimal reproducible example。我还注意到，在单个查询中，您在 31467 和 25832 之间来回转换几何图形 18 次（！）。真的有必要吗？请记住，转换可能需要时间，并且肯定会减慢您的查询速度。如果可能，在函数链的起点或终点进行必要的转换。例如，而不是
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，但取决于您的用例，这无关紧要。尝试这两种方法，并尽可能保持代码整洁。
也就是说，您可以使用 ST_NumGeometries 来计算一列中的几何数：
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
因此您的查询应如下所示：

您的查询相当大，并且由于缺少缩进和工作 fiddle 很难知道问题出在哪里。对于进一步的问题，请考虑创建一个 minimal reproducible example。我还注意到，在单个查询中，您在 31467 和 25832 之间来回转换几何图形 18 次（！）。真的有必要吗？请记住，转换可能需要时间，并且肯定会减慢您的查询速度。如果可能，在函数链的起点或终点进行必要的转换。例如，而不是
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，但取决于您的用例，这无关紧要。尝试这两种方法，并尽可能保持代码整洁。
也就是说，您可以使用 ST_NumGeometries 来计算一列中的几何数：
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
因此您的查询应如下所示：
WITH j AS (
SELECT DISTINCT
ST_MakeEnvelope(
