查询在DocumentDB基于JSON的内在价值 - C#
我有2个对象DocumentDB像下面,查询在DocumentDB基于JSON的内在价值 - C#
{ "TrackGoods": {
"Attributes": {
"Attribute": {
"BlockName": "Default",
"Brand": "Default",
"CaseType": "Carton",
}
},
"Codes": [{
"trackcode": "191155772333RIF1"
},
{
"trackcode": "721141315199RIF2"
}],
"Time": "2017-12-18T13:35:04.0792480+05:30",
"IpAddress": "127.0.0.1",
"Lat": "155.00",
"Long": "-202.00",
}
}
{
"TrackGoods": {
"Attributes": {
"Attribute": {
"BlockName": "Default1",
"Brand": "Default1",
"CaseType": "Carton1",
}
},
"Codes": [{
"trackcode": "191155772333RIF3"
},
{
"trackcode": "721141315199RIF4"
}],
"Time": "2017-12-18T13:35:04.0792480+05:30",
"IpAddress": "127.0.0.1",
"Lat": "155.00",
"Long": "-202.00",
}
}
我想要得到的文件,其中有一个trackcode码=“191155772333RIF1”。
我尝试以下查询,它不会从DocDB返回文档,
string selectdoc = "select doc.TrackGoods from doc join Codes in doc.Codes where Codes.trackcode = '191155772333RIF1'"; query = new SqlQuerySpec(selectdoc,
new SqlParameterCollection(new SqlParameter[] {
new SqlParameter { Name = "@code", Value = code }
}));
任何一个可以帮助我摆脱DocDB文档。
感谢
回答:
我试着用此查询,它似乎正常工作:
select doc.TrackGoods from doc join Codes in doc.TrackGoods.Codes where Codes.trackcode = '191155772333RIF1'
你在in
后失踪的.TrackGoods.
