How to use JSON_VALUE in where in clause (SQL Server) - json

: am trying to use part of a JSON to use as a filter for a where in clause as follows:
declare #json nvarchar(max) =
'[{
"brand_name": {
"key": "Brand Name",
"value": "''alpha'',''omega''"
}
}]';
select *
from someTable
where column in (select json_value(#json, '$[0].brand_name.value'));
How do I convert the value into a where-in argument?


Like this:
declare #json nvarchar(max) =
'[{
"brand_name": {
"key": "Brand Name",
"value": ["alpha","omega"]
}
}]';
select value from openjson(#json, '$[0].brand_name.value')

Parse JSON document into table

I'm working on parsing JSON document with an object array into a SQL Server table. I'm stuck with how to parse the complex object array.
I tried subproject.id and that did not work. I usually use the below code to parse a JSON array which works just fine but in this case it does not.
JSON:
{
"Data": [
{
"name": "ABC",
"date": "2020-01-20",
"subproject": [
{
"id": "123",
"projectname": "new1",
"refnum": "123:new1"
},
{
"id": "456",
"projectname": "new2",
"refnum": "456:new2"
}
],
"projectid": "1234",
"projectdate": "2020-01-27"
},
{
"name": "DEF",
"date": "2020-01-30",
"subproject": [
{
"id": "789",
"projectname": "new3",
"refnum": "789:new3"
},
{
"id": "901",
"projectname": "new4",
"refnum": "901:new4"
}
],
"projectid": "4567",
"projectdate": "2020-02-07"
}
]
}
SQL:
DECLARE #JSON VARCHAR(MAX)
SELECT #JSON = BulkColumn
FROM OPENROWSET (BULK 'c:/data/project.json', SINGLE_CLOB) X
SELECT *
FROM OPENJSON (#JSON)
WITH (
[name] NVARCHAR(256),
[date] DATE,
[projectid] INT,
[projectdate] DATE
)

You need to use AS JSON clause in the first OPENJSON() call (to specify that the $.subproject property contains an inner JSON array) and a combination of another OPENJSON() call and APPLY operator:
SELECT *
FROM OPENJSON (#JSON, '$.Data') WITH (
[name] NVARCHAR(256),
[date] DATE,
[projectid] INT,
[projectdate] DATE,
[subproject] NVARCHAR(MAX) '$.subproject' AS JSON
) j1
OUTER APPLY OPENJSON (j1.[subproject]) WITH (
[subprojectid] INT '$.id',
[subprojectname] NVARCHAR(256) '$.projectname',
[subprojectrefnum] NVARCHAR(256) '$.refnum'
) j2

MS SQL Json array processing with separate arrays

I have a problem with JSON data and how to get it in SQL table so the data is:
[
{
"id":"1121131",
"idGroups":[
"123",
"X999"
],
"idGroupNames":[
"Neutral",
"Service"
]
},
{
"id":"2233154",
"idGroups":[
"654321"
],
"idGroupNames":[
"Position"
]
}
]
and the desired output is
Id
idGroups
idGroupNames
1121131
123
Neutral
1121131
X999
Service
2233154
654321
Position
I have trying to get the desired result with OPENJSON() and CROSS APPLY, but I think that I'm not getting anywhere.
my original attempt was
DECLARE #json NVARCHAR(MAX) = N'[
{
"id":"1121131",
"idGroups":[
"123",
"X999"
],
"idGroupNames":[
"Neutral",
"Service"
]
},
{
"id":"2233154",
"idGroups":[
"654321"
],
"idGroupNames":[
"Position"
]
}
]'
SELECT id,idGroup,idGroupName FROM OPENJSON (#json)
WITH (
id INT 'strict $.id',
idGroups NVARCHAR(MAX) '$.idGroups' AS JSON,
idGroupNames NVARCHAR(MAX) '$.idGroupNames' AS JSON
) CROSS APPLY OPENJSON(idGroups)
WITH (
idGroup VARCHAR(500) '$'
) CROSS APPLY OPENJSON(idGroupNames)
WITH (
idGroupName VARCHAR(500) '$'
)

You need to use OPENJSON() with default schema and two additional APPLY operators. The following statement is a possible solution to your problem:
JSON:
DECLARE #json nvarchar(max) = N'[
{
"id":"1121131",
"idGroups":[
"123",
"X999"
],
"idGroupNames":[
"Neutral",
"Service"
]
},
{
"id":"2233154",
"idGroups":[
"654321"
],
"idGroupNames":[
"Position"
]
}
]'
Statement:
SELECT j.id, j1.[value] AS idGroups, j2.[value] AS idGroupNames
FROM OPENJSON(#json) WITH (
id nvarchar(7) '$.id',
idGroups nvarchar(max) '$.idGroups' AS JSON,
idGroupNames nvarchar(max) '$.idGroupNames' AS JSON
) j
CROSS APPLY OPENJSON(j.idGroups) j1
CROSS APPLY OPENJSON(j.idGroupNames) j2
WHERE j1.[key] = j2.[key]

You can do it without a third OPENJSON, using JSON_VALUE and a dynamic path.
This only works in SQL Server 2017+
DECLARE #json nvarchar(max) = N'[
{
"id":"1121131",
"idGroups":[
"123",
"X999"
],
"idGroupNames":[
"Neutral",
"Service"
]
},
{
"id":"2233154",
"idGroups":[
"654321"
],
"idGroupNames":[
"Position"
]
}
]';
SELECT j.id, j1.[value] AS idGroups, JSON_VALUE(j.idGroupNames, '$[' + j1.[key] + ']') AS idGroupNames
FROM OPENJSON(#json) WITH (
id nvarchar(7) '$.id',
idGroups nvarchar(max) '$.idGroups' AS JSON,
idGroupNames nvarchar(max) '$.idGroupNames' AS JSON
) j
CROSS APPLY OPENJSON(j.idGroups) j1;

Remove elements from a JSON array, with no key

I'm looking for a way that I can remove elements from a JSON array in SQL Server, I tried using JSON_MODIFY/OPENPATH, but I can't seem to get the path parameter correct.
Here is an example of what I want to do is convert:
[{"FieldName":"OrderStatusTypeId","FieldType":"Int32","ValueBefore":"8","ValueAfter":"10","Action":2},{"FieldName":"PatientReferenceNumber","FieldType":"String","ValueBefore":"","ValueAfter":"","Action":2}]
To be:
[{"FieldName":"OrderStatusTypeId","FieldType":"Int32","ValueBefore":"8","ValueAfter":"10","Action":2}]
Basically, I want to remove any element of the array, whereby the Action is 2 and the ValueBefore and the ValueAfter fields are the same.
Here is what I'm attempting at the moment, as a test, but I keep getting the error below:
DECLARE #JSONData AS NVARCHAR(4000)
SET #JSONData = N'[{"FieldName":"OrderStatusTypeId","FieldType":"Int32","ValueBefore":"8","ValueAfter":"10","Action":2},{"FieldName":"PatientReferenceNumber","FieldType":"String","ValueBefore":"","ValueAfter":"","Action":2},{"FieldName":"PoNumber","FieldType":"String","ValueBefore":"","ValueAfter":"","Action":2},{"FieldName":"ReferringPhysicianName","FieldType":"String","ValueBefore":"","ValueAfter":"","Action":2},{"FieldName":"InsuranceProvider","FieldType":"String","ValueBefore":"","ValueAfter":"","Action":2},{"FieldName":"TreatmentId","FieldType":"String","ValueBefore":"","ValueAfter":"","Action":2},{"FieldName":"RowVersion[6]","FieldType":"Byte","ValueBefore":"10","ValueAfter":"115","Action":2},{"FieldName":"OrderStatusType.Id","FieldType":"Int32","ValueBefore":"8","ValueAfter":"10","Action":2},{"FieldName":"OrderStatusType.Description","FieldType":"String","ValueBefore":"Delivered","ValueAfter":"Failed Logistics","Action":2},{"FieldName":"OrderStatusType.IsSelectable","FieldType":"Boolean","ValueBefore":"False","ValueAfter":"True","Action":2}]'
SELECT #JSONData = JSON_MODIFY(#JSONData, '$',
JSON_QUERY(
(
SELECT *
FROM OPENJSON(#JSONData, '$') WITH (
FieldName nvarchar(1000) '$.FieldName',
FieldType nvarchar(1000) '$.FieldType',
ValueBefore nvarchar(1000) '$.ValueBefore',
ValueAfter nvarchar(1000) '$.ValueAfter',
Action int '$.Action'
)
WHERE Action <> 2 AND ValueBefore <> ValueAfter
FOR JSON PATH
)
)
)
Error:
Msg 13619, Level 16, State 1, Line 4
Unsupported JSON path found in argument 2 of JSON_MODIFY.
The expected output I'm looking for is:
[{"FieldName":"OrderStatusTypeId","FieldType":"Int32","ValueBefore":"8","ValueAfter":"10","Action":2},{"FieldName":"RowVersion[6]","FieldType":"Byte","ValueBefore":"10","ValueAfter":"115","Action":2},{"FieldName":"OrderStatusType.Id","FieldType":"Int32","ValueBefore":"8","ValueAfter":"10","Action":2},{"FieldName":"OrderStatusType.Description","FieldType":"String","ValueBefore":"Delivered","ValueAfter":"Failed Logistics","Action":2},{"FieldName":"OrderStatusType.IsSelectable","FieldType":"Boolean","ValueBefore":"False","ValueAfter":"True","Action":2}]
How can I work out the correct JSON Path value, all the examples I seem to find online don't have an array as the root element of the JSON string.
Note, the order of the elements isn't important.

You don't have to use JSON_MODIFY here. You can just select the data you want as a table, filter it, then re-encode it as JSON.
DECLARE #JSONData AS NVARCHAR(4000)
SET #JSONData = N'[{"FieldName":"OrderStatusTypeId","FieldType":"Int32","ValueBefore":"8","ValueAfter":"10","Action":2},{"FieldName":"PatientReferenceNumber","FieldType":"String","ValueBefore":"","ValueAfter":"","Action":2},{"FieldName":"PoNumber","FieldType":"String","ValueBefore":"","ValueAfter":"","Action":2},{"FieldName":"ReferringPhysicianName","FieldType":"String","ValueBefore":"","ValueAfter":"","Action":2},{"FieldName":"InsuranceProvider","FieldType":"String","ValueBefore":"","ValueAfter":"","Action":2},{"FieldName":"TreatmentId","FieldType":"String","ValueBefore":"","ValueAfter":"","Action":2},{"FieldName":"RowVersion[6]","FieldType":"Byte","ValueBefore":"10","ValueAfter":"115","Action":2},{"FieldName":"OrderStatusType.Id","FieldType":"Int32","ValueBefore":"8","ValueAfter":"10","Action":2},{"FieldName":"OrderStatusType.Description","FieldType":"String","ValueBefore":"Delivered","ValueAfter":"Failed Logistics","Action":2},{"FieldName":"OrderStatusType.IsSelectable","FieldType":"Boolean","ValueBefore":"False","ValueAfter":"True","Action":2}]'
set #JSONData =
(
SELECT *
FROM OPENJSON(#JSONData, '$') WITH (
FieldName nvarchar(1000) '$.FieldName',
FieldType nvarchar(1000) '$.FieldType',
ValueBefore nvarchar(1000) '$.ValueBefore',
ValueAfter nvarchar(1000) '$.ValueAfter',
Action int '$.Action'
)
WHERE not (Action = 2 and ValueBefore = ValueAfter)
FOR JSON PATH
)
and the JSON is
[
{
"FieldName": "OrderStatusTypeId",
"FieldType": "Int32",
"ValueBefore": "8",
"ValueAfter": "10",
"Action": 2
},
{
"FieldName": "RowVersion[6]",
"FieldType": "Byte",
"ValueBefore": "10",
"ValueAfter": "115",
"Action": 2
},
{
"FieldName": "OrderStatusType.Id",
"FieldType": "Int32",
"ValueBefore": "8",
"ValueAfter": "10",
"Action": 2
},
{
"FieldName": "OrderStatusType.Description",
"FieldType": "String",
"ValueBefore": "Delivered",
"ValueAfter": "Failed Logistics",
"Action": 2
},
{
"FieldName": "OrderStatusType.IsSelectable",
"FieldType": "Boolean",
"ValueBefore": "False",
"ValueAfter": "True",
"Action": 2
}
]

How to call Json in sql query

I want to display the parameter ST and NextTime from table #json. The parameters id and Timestamp appear normally. I try the following but does not show any effect.Any possible answers?
My Json
{
"PCol": [{
"Id": 15,
"TimeStamp": "2018-02-1",
"Val": {
"States": [{
"Numbers": {
"Number": [5, 8]
},
"CS": {
"ST": "25"
},
"Changes": [{
"NextTime": 1
}]
}]
}
}]
}
My Sql Query
SELECT * FROM OPENJSON((select * from #json),N'$.PCol')
WITH (
[Id] INT N'$.Id ',
[TimeStamp] NVARCHAR(MAX) N'$.TimeStamp',
**[ST] INT N'$.Val.States.CS.ST'**
)
Thanks

Not going to lie, my OPENJSON knowledge is poor (so this might be able to be more succinct), however, this works:
DECLARE #JSON nvarchar(MAX) =
N' {
"PCol": [{
"Id": 15,
"TimeStamp": "2018-02-1",
"Val": {
"States": [{
"Numbers": {
"Number": [5, 8]
},
"CS": {
"ST": "25"
}
}]
}
}]
} ';
SELECT P.Id,
P.TimeStamp,
V.ST
FROM OPENJSON(#JSON,N'$.PCol') WITH ([Id] INT N'$.Id ',
[TimeStamp] NVARCHAR(MAX) N'$.TimeStamp',
[Vals] nvarchar(MAX) N'$.Val' AS JSON) P
CROSS APPLY OPENJSON(P.Vals,N'$.States') WITH (ST int N'$.CS.ST') V
For the latest JSON, this works:
SELECT P.Id,
P.TimeStamp,
V.ST,
C.NextTime
FROM OPENJSON(#JSON,N'$.PCol') WITH ([Id] INT N'$.Id ',
[TimeStamp] NVARCHAR(MAX) N'$.TimeStamp',
[Vals] nvarchar(MAX) N'$.Val' AS JSON) P
CROSS APPLY OPENJSON(P.Vals,N'$.States') WITH (ST int N'$.CS.ST',
[Changes] nvarchar(MAX) N'$.Changes' AS JSON) V
CROSS APPLY OPENJSON(V.[Changes]) WITH (NextTime int '$.NextTime') C

Remove array from json object stored in SQL Server column

If I have the following JSON stored in a column in SQL Server:
declare #json nvarchar(max) = '[{"id": "1", "name": "test1"},{"id": "2", "name": "test2"},{"id": "3", "name": "test4"}]'
how can I remove an array where Id:=1 ?
I want to get the following result:
[{"id": "2", "name": "test2"},{"id": "3", "name": "test4"}]

try this:
declare #json nvarchar(max) = '[{"id": "1", "name": "test1"},{"id": "2", "name": "test2"},{"id": "3", "name": "test4"}]';
DECLARE #IdTobeRemoved INT =1;
DECLARE #StartIndex INT
DECLARE #EndIndex INT
DECLARE #tempjson nvarchar(max)
SELECT #StartIndex = CHARINDEX('"id": "'+CONVERT(VARCHAR(10),#IdTobeRemoved)+'"',#json)-2
SELECT #tempjson = STUFF(#json, 1, #StartIndex, '')
SELECT #EndIndex =
CASE WHEN SUBSTRING(#tempjson,CHARINDEX('}',#tempjson)+1,1)=']'
THEN CHARINDEX('}',#tempjson)+1
ELSE CHARINDEX('}',#tempjson)+2
END
SELECT REPLACE(REPLACE(#json,SUBSTRING(#tempjson,0,#EndIndex),''),'},]','}]')
