Question

WITH values(location, userid) as (
VALUES (st_geomfromewkt('0101000000000000C04141464000000000FE174440'),5))

SELECT st_distance(p.location,(SELECT location FROM values where v.userid = "blacklisterId")::geometry)
FROM values as v,live.partners as p
Inner JOIN backend.cars c ON (c."userId" = p."partnerId" AND c.active = true)
Inner JOIN backend."carCompatibleTariffs" cCT ON c."carId" = cCT."carId" and  1 = cCT."tariffId" AND cCT.active = true
LEFT JOIN backend."userBlacklist" bl on 5 = bl."blacklisterId" AND p."partnerId" = bl."blacklistedId"
WHERE bl."blacklistedId" ISNULL
--AND st_dwithin(p.location::geography,(SELECT FROM values where v.userid = "blacklisterId")::geography,1500)
--ORDER BY st_distance(p.location,(SELECT location FROM values where v.userid = "blacklisterId")::geometry) ASC;

如何将文本值表作为几何或地理，我尝试使用ST_GeographyFromText，ST_GeogmetryFromText和st_makepoint（（选择st_x），（选择st_y）），但它总是返回null，我该如何解决？< / p>

Answer 1

您的问题可能在其他地方。您的几何图形似乎有效：

WITH values(location, userid) AS 
(VALUES ('0101000000000000C04141464000000000FE174440',5),
        ('0101000000000000200A45464000000000D7174440',16))
SELECT ST_Distance(location::GEOMETRY,ST_GeomFromText('POINT(44 45)')) FROM values;

这里有几个关于不同类型的几何文字的例子：

ST_GeomFromText

db=# SELECT ST_GeomFromText('POINT(1 2)');
              st_geomfromtext               
--------------------------------------------
 0101000000000000000000F03F0000000000000040
(1 Zeile)

ST_GeomFromGeoJSON：

db=# SELECT ST_GeomFromGeoJSON('{"type":"Point","coordinates":[1,2]}');
             st_geomfromgeojson             
--------------------------------------------
 0101000000000000000000F03F0000000000000040
(1 Zeile)

ST_GeomFromEWKT：

db=# SELECT ST_GeomFromEWKT('SRID=4269;POINT(1 2)');
                  st_geomfromewkt                   
----------------------------------------------------
 0101000020AD100000000000000000F03F0000000000000040

ST_GeomFromGML：

db=# SELECT ST_GeomFromGML('<gml:Point><gml:coordinates>1,2</gml:coordinates></gml:Point>');
               st_geomfromgml               
--------------------------------------------

ST_GeomFromKML：

db=# SELECT ST_GeomFromKML('<Point><coordinates>1,2</coordinates></Point>');
                   st_geomfromkml

这个可以是你的意图：

$schedule->job(new CustomCommand)->everyFiveMinutes();

从声明到地理和地理的文字
