我想更新属性中的数组...

示例：我想更改属性where Name = ProofCycle中的值。

想要一种通过Json_Modify函数更新json的动态方式。

我有一些查询要拉平json，但是json_Modify不能更改数组中的值

DECLARE @KeyValue NVARCHAR(MAX) = '{"JobID":1005,"ItemID":2,"Prefix":"CC","Version":1,"ItemTypeID":4,"ItemType":"Change Control","StageID":3,"StageName":"Change Control Closure","WorkflowID":1,"WorkflowName":"Change Control Workflow","JobStatus":0,"IsJobArchived":false,"IsJobCanceled":false,"IsJobOnHold":false,"IsJobPhasedOut":false,"RelationID":0,"JobLastUpdatedBy":"G4Admin","JobStartDate":"2019-07-18T08:02:44.737718Z","JobLastUpdated":"2019-07-18T08:02:44.9857249Z","JobDueDate":"2019-07-23T08:02:44.8997205Z","JobEstimatedDate":"2019-07-23T08:02:44.8877188Z","JobCompletedDate":null,"RevisionNumber":1,"DocketNo":390,"JobVariance":"0","Mappings":[],"Groups":[12],"InactiveGroups":null,"Attributes":[{"ID":22,"Name":"WorkflowType","Value":"50","DataType":"Text","IsMaster":true,"ItemData":true,"IsUserGroup":false,"GroupId":null,"ValueString":"Change Control","InactiveValue":null,"InactiveValueString":null},{"ID":18,"Name":"Reason for change","Value":"23","DataType":"Text","IsMaster":true,"ItemData":true,"IsUserGroup":false,"GroupId":null,"ValueString":"CMC change","InactiveValue":null,"InactiveValueString":null},{"ID":12,"Name":"Market","Value":"12","DataType":"Text","IsMaster":true,"ItemData":true,"IsUserGroup":true,"GroupId":null,"ValueString":"Ireland","InactiveValue":null,"InactiveValueString":null},{"ID":14,"Name":"Product Name","Value":"34","DataType":"Text","IsMaster":true,"ItemData":true,"IsUserGroup":false,"GroupId":null,"ValueString":"DROXIA","InactiveValue":null,"InactiveValueString":null},{"ID":13,"Name":"CCDS Impacted?","Value":"15","DataType":"Text","IsMaster":true,"ItemData":true,"IsUserGroup":false,"GroupId":null,"ValueString":"No","InactiveValue":null,"InactiveValueString":null},{"ID":11,"Name":"JobOwner","Value":"G4Admin","DataType":"Text","IsMaster":false,"ItemData":true,"IsUserGroup":false,"GroupId":null,"ValueString":"G4Admin","InactiveValue":null,"InactiveValueString":null},{"ID":50,"Name":"PartNumber","Value":"CC-02-01","DataType":0,"IsMaster":false,"ItemData":false,"IsUserGroup":false,"GroupId":null,"ValueString":"CC-02-01","InactiveValue":null,"InactiveValueString":null},{"ID":50,"Name":"JobInitiator","Value":"G4Admin","DataType":0,"IsMaster":false,"ItemData":false,"IsUserGroup":false,"GroupId":null,"ValueString":"G4Admin","InactiveValue":null,"InactiveValueString":null},{"ID":10,"Name":"TaskLeft","Value":"3","DataType":0,"IsMaster":false,"ItemData":false,"IsUserGroup":false,"GroupId":null,"ValueString":null,"InactiveValue":null,"InactiveValueString":null},{"ID":4,"Name":"ProofCycle","Value":"1","DataType":"Integer","IsMaster":false,"ItemData":true,"IsUserGroup":false,"GroupId":null,"ValueString":"1","InactiveValue":null,"InactiveValueString":null},{"ID":5,"Name":"PassCycle","Value":"1","DataType":"Integer","IsMaster":false,"ItemData":true,"IsUserGroup":false,"GroupId":null,"ValueString":"1","InactiveValue":null,"InactiveValueString":null},{"ID":6,"Name":"TotalPassCount","Value":"1","DataType":"Integer","IsMaster":false,"ItemData":true,"IsUserGroup":false,"GroupId":null,"ValueString":"1","InactiveValue":null,"InactiveValueString":null}],"LinkedParentJobs":[],"LinkedChildJobs":[],"FullText":null}'

SELECT 
    -- Change Value to 80 where Name = 'Passcycle'
    JSON_MODIFY(@KeyValue, '$.Attributes', '80')

我得到一个空输出。

有人可以帮我解决这个问题吗？

Answer 1

说明：

您可以使用"Attributes" JSON路径表达式访问和修改$.Attributes[x].Value数组中的项目，其中x是该项目的索引。您需要将此路径表达式传递给JSON_MODIFY。因此，这里一种可能的方法是生成并执行动态语句。但是，如果您使用SQL Server 2017+，则可以提供一个变量作为此路径表达式的值。

动态语句（SQL Server 2016 +）：

DECLARE @KeyValue NVARCHAR(MAX) = N'{"JobID":1005,"ItemID":2,"Prefix":"CC","Version":1,"ItemTypeID":4,"ItemType":"Change Control","StageID":3,"StageName":"Change Control Closure","WorkflowID":1,"WorkflowName":"Change Control Workflow","JobStatus":0,"IsJobArchived":false,"IsJobCanceled":false,"IsJobOnHold":false,"IsJobPhasedOut":false,"RelationID":0,"JobLastUpdatedBy":"G4Admin","JobStartDate":"2019-07-18T08:02:44.737718Z","JobLastUpdated":"2019-07-18T08:02:44.9857249Z","JobDueDate":"2019-07-23T08:02:44.8997205Z","JobEstimatedDate":"2019-07-23T08:02:44.8877188Z","JobCompletedDate":null,"RevisionNumber":1,"DocketNo":390,"JobVariance":"0","Mappings":[],"Groups":[12],"InactiveGroups":null,"Attributes":[{"ID":22,"Name":"WorkflowType","Value":"50","DataType":"Text","IsMaster":true,"ItemData":true,"IsUserGroup":false,"GroupId":null,"ValueString":"Change Control","InactiveValue":null,"InactiveValueString":null},{"ID":18,"Name":"Reason for change","Value":"23","DataType":"Text","IsMaster":true,"ItemData":true,"IsUserGroup":false,"GroupId":null,"ValueString":"CMC change","InactiveValue":null,"InactiveValueString":null},{"ID":12,"Name":"Market","Value":"12","DataType":"Text","IsMaster":true,"ItemData":true,"IsUserGroup":true,"GroupId":null,"ValueString":"Ireland","InactiveValue":null,"InactiveValueString":null},{"ID":14,"Name":"Product Name","Value":"34","DataType":"Text","IsMaster":true,"ItemData":true,"IsUserGroup":false,"GroupId":null,"ValueString":"DROXIA","InactiveValue":null,"InactiveValueString":null},{"ID":13,"Name":"CCDS Impacted?","Value":"15","DataType":"Text","IsMaster":true,"ItemData":true,"IsUserGroup":false,"GroupId":null,"ValueString":"No","InactiveValue":null,"InactiveValueString":null},{"ID":11,"Name":"JobOwner","Value":"G4Admin","DataType":"Text","IsMaster":false,"ItemData":true,"IsUserGroup":false,"GroupId":null,"ValueString":"G4Admin","InactiveValue":null,"InactiveValueString":null},{"ID":50,"Name":"PartNumber","Value":"CC-02-01","DataType":0,"IsMaster":false,"ItemData":false,"IsUserGroup":false,"GroupId":null,"ValueString":"CC-02-01","InactiveValue":null,"InactiveValueString":null},{"ID":50,"Name":"JobInitiator","Value":"G4Admin","DataType":0,"IsMaster":false,"ItemData":false,"IsUserGroup":false,"GroupId":null,"ValueString":"G4Admin","InactiveValue":null,"InactiveValueString":null},{"ID":10,"Name":"TaskLeft","Value":"3","DataType":0,"IsMaster":false,"ItemData":false,"IsUserGroup":false,"GroupId":null,"ValueString":null,"InactiveValue":null,"InactiveValueString":null},{"ID":4,"Name":"ProofCycle","Value":"1","DataType":"Integer","IsMaster":false,"ItemData":true,"IsUserGroup":false,"GroupId":null,"ValueString":"1","InactiveValue":null,"InactiveValueString":null},{"ID":5,"Name":"PassCycle","Value":"1","DataType":"Integer","IsMaster":false,"ItemData":true,"IsUserGroup":false,"GroupId":null,"ValueString":"1","InactiveValue":null,"InactiveValueString":null},{"ID":6,"Name":"PassCycle","Value":"1","DataType":"Integer","IsMaster":false,"ItemData":true,"IsUserGroup":false,"GroupId":null,"ValueString":"1","InactiveValue":null,"InactiveValueString":null}],"LinkedParentJobs":[],"LinkedChildJobs":[],"FullText":null}'

DECLARE @stm nvarchar(max) = N''
SELECT @stm = @stm + CONCAT(
   'SELECT @KeyValue = JSON_MODIFY(@KeyValue, ''$.Attributes[',
   [key],
   '].Value'', ''80''); '
)   
FROM OPENJSON(@keyValue, '$.Attributes')
WHERE JSON_VALUE([value], '$.Name') = N'PassCycle'

EXECUTE sp_executesql @stm, N'@KeyValue NVARCHAR(MAX) OUTPUT', @KeyValue OUTPUT

使用变量作为path表达式（SQL Server 2017 +）：

DECLARE @KeyValue NVARCHAR(MAX) = N'{"JobID":1005,"ItemID":2,"Prefix":"CC","Version":1,"ItemTypeID":4,"ItemType":"Change Control","StageID":3,"StageName":"Change Control Closure","WorkflowID":1,"WorkflowName":"Change Control Workflow","JobStatus":0,"IsJobArchived":false,"IsJobCanceled":false,"IsJobOnHold":false,"IsJobPhasedOut":false,"RelationID":0,"JobLastUpdatedBy":"G4Admin","JobStartDate":"2019-07-18T08:02:44.737718Z","JobLastUpdated":"2019-07-18T08:02:44.9857249Z","JobDueDate":"2019-07-23T08:02:44.8997205Z","JobEstimatedDate":"2019-07-23T08:02:44.8877188Z","JobCompletedDate":null,"RevisionNumber":1,"DocketNo":390,"JobVariance":"0","Mappings":[],"Groups":[12],"InactiveGroups":null,"Attributes":[{"ID":22,"Name":"WorkflowType","Value":"50","DataType":"Text","IsMaster":true,"ItemData":true,"IsUserGroup":false,"GroupId":null,"ValueString":"Change Control","InactiveValue":null,"InactiveValueString":null},{"ID":18,"Name":"Reason for change","Value":"23","DataType":"Text","IsMaster":true,"ItemData":true,"IsUserGroup":false,"GroupId":null,"ValueString":"CMC change","InactiveValue":null,"InactiveValueString":null},{"ID":12,"Name":"Market","Value":"12","DataType":"Text","IsMaster":true,"ItemData":true,"IsUserGroup":true,"GroupId":null,"ValueString":"Ireland","InactiveValue":null,"InactiveValueString":null},{"ID":14,"Name":"Product Name","Value":"34","DataType":"Text","IsMaster":true,"ItemData":true,"IsUserGroup":false,"GroupId":null,"ValueString":"DROXIA","InactiveValue":null,"InactiveValueString":null},{"ID":13,"Name":"CCDS Impacted?","Value":"15","DataType":"Text","IsMaster":true,"ItemData":true,"IsUserGroup":false,"GroupId":null,"ValueString":"No","InactiveValue":null,"InactiveValueString":null},{"ID":11,"Name":"JobOwner","Value":"G4Admin","DataType":"Text","IsMaster":false,"ItemData":true,"IsUserGroup":false,"GroupId":null,"ValueString":"G4Admin","InactiveValue":null,"InactiveValueString":null},{"ID":50,"Name":"PartNumber","Value":"CC-02-01","DataType":0,"IsMaster":false,"ItemData":false,"IsUserGroup":false,"GroupId":null,"ValueString":"CC-02-01","InactiveValue":null,"InactiveValueString":null},{"ID":50,"Name":"JobInitiator","Value":"G4Admin","DataType":0,"IsMaster":false,"ItemData":false,"IsUserGroup":false,"GroupId":null,"ValueString":"G4Admin","InactiveValue":null,"InactiveValueString":null},{"ID":10,"Name":"TaskLeft","Value":"3","DataType":0,"IsMaster":false,"ItemData":false,"IsUserGroup":false,"GroupId":null,"ValueString":null,"InactiveValue":null,"InactiveValueString":null},{"ID":4,"Name":"ProofCycle","Value":"1","DataType":"Integer","IsMaster":false,"ItemData":true,"IsUserGroup":false,"GroupId":null,"ValueString":"1","InactiveValue":null,"InactiveValueString":null},{"ID":5,"Name":"PassCycle","Value":"1","DataType":"Integer","IsMaster":false,"ItemData":true,"IsUserGroup":false,"GroupId":null,"ValueString":"1","InactiveValue":null,"InactiveValueString":null},{"ID":6,"Name":"PassCycle","Value":"1","DataType":"Integer","IsMaster":false,"ItemData":true,"IsUserGroup":false,"GroupId":null,"ValueString":"1","InactiveValue":null,"InactiveValueString":null}],"LinkedParentJobs":[],"LinkedChildJobs":[],"FullText":null}'

SELECT @KeyValue = JSON_MODIFY(@KeyValue, '$.Attributes[' + [key] + '].Value', '80')
FROM OPENJSON(@keyValue, '$.Attributes')
WHERE JSON_VALUE([value], '$.Name') = N'PassCycle'

注释：

两个示例都将修改条件为JSON的{{1}}数组中的所有项目（不仅是一项）。
