            If readily available. Otherwise, if the instrumentation library parses `db.query.text` to capture
            `db.operation.name`, then it SHOULD be the first operation name found in the query.
      - ref: server.address
        brief: >
          Name of the database host.
      - ref: server.port
        requirement_level:
          conditionally_required: If using a port other than the default port for this DBMS and if `server.address` is set.
      - ref: error.type
        requirement_level:
          conditionally_required: If and only if the operation failed.
        note: >
          The `error.type` SHOULD match the error code returned by the database or the client library,
          the canonical name of exception that occurred, or another low-cardinality error identifier.
          Instrumentations SHOULD document the list of errors they report.
