我试图找出解析在SQL Server中存储为字符串的复杂JSON对象的最佳方法.
我的表有以下信息:
LogID | Content
-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
55271413 | {"LicensePlate":"","FreightHaulerProviderXId":"ABC","FreightProviderReferenceNumber":"5218912","CarrierScac":"XYZ","Latitude":33.595555,"Longitude":-85.854722,"StreetAddress1":"","StreetAddress2":"","City":"","State":"","PostalCode":"","Country":""}
55271414 | {"LicensePlate":"","FreightHaulerProviderXId":"ABC","FreightProviderReferenceNumber":"5218944","CarrierScac":"XYZ","Latitude":37.996666,"Longitude":-78.314444,"StreetAddress1":"","StreetAddress2":"","City":"","State":"","PostalCode":"","Country":""}
55271415 | {"LicensePlate":"","FreightHaulerProviderXId":"ABC","FreightProviderReferenceNumber":"5219079","CarrierScac":"YZB","Latitude":34.027500,"Longitude":-117.522222,"StreetAddress1":"","StreetAddress2":"","City":"","State":"","PostalCode":"","Country":""}
55271416 | {"LicensePlate":"","FreightHaulerProviderXId":"ABC","FreightProviderReferenceNumber":"5219020","CarrierScac":"XYZ","Latitude":37.754722,"Longitude":-121.144166,"StreetAddress1":"","StreetAddress2":"","City":"","State":"","PostalCode":"","Country":""}
55271417 | {"LicensePlate":"","FreightHaulerProviderXId":"ABC","FreightProviderReferenceNumber":"5218911","CarrierScac":"XYZ","Latitude":40.585833,"Longitude":-91.425000,"StreetAddress1":"","StreetAddress2":"","City":"","State":"","PostalCode":"","Country":""}
55271418 | {"LicensePlate":"","FreightHaulerProviderXId":"ABC","FreightProviderReferenceNumber":"5218785","CarrierScac":"XYZ","Latitude":30.747500,"Longitude":-85.270277,"StreetAddress1":"","StreetAddress2":"","City":"","State":"","PostalCode":"","Country":""}
55271426 | {"LicensePlate":"","FreightHaulerProviderXId":"ABC","FreightProviderReferenceNumber":"5219044","CarrierScac":"XYZ","Latitude":33.598333,"Longitude":-97.936388,"StreetAddress1":"","StreetAddress2":"","City":"","State":"","PostalCode":"","Country":""}
我正在尝试解析每个字符串并将其放在一个新列中,其中JSON属性的名称作为列名,相应的值作为行值.
例如,以下是我在下面为每行寻找的结果:
LogID | LicensePlate | FreightHaulerProviderXId | FreightProviderReferenceNumber | CarrierScac | Latitude | Longitude | StreetAddress1 | StreetAddress2 | City | State | PostalCode | Country
-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
55271413 | | ABC | 5218912 | XYZ | 33.595555 | -85.854722 | | | | | |
我尝试使用一些非常糟糕的SQL逻辑来解析它.基本上我查找整个字符串,获取子字符串,然后手动分配列名.对于可伸缩性和性能而言,这不是一个非常好的解决方案.
SELECT DISTINCT
SUBSTRING(lcon.Content, CHARINDEX('CarrierScac', lcon.Content)+14, …
