  title: Azure Log Analytics Inspect Table Schema then Query
  summary: List a workspace's tables, inspect one table's schema, then query that table.
  description: >-
    A schema-aware querying pattern. Before running a KQL query the workflow
    enumerates the tables in a Log Analytics workspace and reads the schema of
    the chosen table so the caller knows the available columns. It then executes
    a KQL query that targets that table. Every step spells out its request inline
    so the flow can be read and executed without opening the underlying OpenAPI
    descriptions.

  summary: Enumerate workspace tables, read one table's schema, then query it.
  description: >-
    Lists the tables in a workspace, reads the management definition of the
    chosen table to expose its column schema, retention, and plan, and then runs
    a KQL query against that table on the query endpoint.
