标题关键字的 Kusto 查询问题

Kusto query issue with title keyword

我假设 title 可能是保留字或类似词,但下面的查询拒绝围绕 c.title 进行解析。不确定查询本身到底有什么问题

AzureActivity
| where CategoryValue == "ResourceHealth" and ResourceProviderValue == "MICROSOFT.COMPUTE"
| where not (ResourceGroup startswith "DATABRICKS-RG")
| extend d=parse_json(Properties)
| extend c = parse_json(tostring(d.eventProperties))
| where c.cause == "PlatformInitiated" and not(c.title == "Live Migration")

显示错误

 SYNTAX ERROR

Query could not be parsed at '.' on line [6,48]

Token: .

If issue persists, please open a support ticket.

因为 title 是该语言中的保留关键字,您可以将 c.title 替换为 c['title']
