Question

我有地理围栏表中的经度和纬度如何检查数据库级别的经度和纬度。如果汽车经度纬度是在开发区，更新geofance列区=

CREATE TRIGGER Tr_CheckGeoFance 
ON CheckGeoFance 
AFTER INSERT AS 
BEGIN 
Update tblgeofencing 
Set CarZone ='Car In Zone Area' 
END 
GO 
ShapesString ={"shapes":[{"type":"rectangle","color":"#1E90FF","bounds":{"northEast":{"lat":"32.379961464357315","lon":"70.99365234375"},"southWest":{"lat":"31.840232667909362","lon":"70.2685546875"}}}]} 

Answer 1

至上“区区域汽车”你必须给ShapesString这是目前JSON格式解码和然后从解码的json中找出经度和纬度。 然后检查您定义的范围内的经纬度数据以更新列。

转寄此将JSON解码： - Parse JSON in TSQL
