syspolicy_policy_execution_history_details (Transact-SQL)
Displays the condition expressions that were executed, the targets of the expressions, the result of each execution, and details about errors if any occurred. The following table describes the columns in the syspolicy_execution_history_details view.
Column name |
Data type |
Description |
|---|---|---|
detail_id |
bigint |
Identifier of this record. Each record represents the attempt to evaluate or enforce one condition expression in a policy. If applied to multiple targets, each condition will have a detail record for each target. |
history_id |
bigint |
Identifier of the history event. Each history event represents one try to execute a policy. Because a condition can have several condition expressions and several targets, a history_id can create several detail records. Use the history_id column to join this view to the syspolicy_policy_execution_history view. |
target_query_expression |
nvarchar(max) |
Target of the policy and syspolicy_policy_execution_history view. |
execution_date |
datetime |
Date and time that this detail record was created. |
result |
bit |
Success or failure of this target and condition expression evaluation: 0 (success) or 1 (failure). |
result_detail |
nvarchar(max) |
Result message. Only available if provided by the facet. |
exception_message |
nvarchar(max) |
Message generated by the exception if one occurred. |
exception |
nvarchar(max) |

PolHistDet.execution_date,
PolHistDet.result,
PolHistDet.result_detail,
PolHistDet.exception_message,
PolHistDet.exception
FROM msdb.dbo.syspolicy_policies AS Pol
JOIN msdb.dbo.syspolicy_conditions AS Cond
ON Pol.condition_id = Cond.condition_id
JOIN msdb.dbo.syspolicy_policy_execution_history AS PolHist
ON Pol.policy_id = PolHist.policy_id
JOIN msdb.dbo.syspolicy_policy_execution_history_details AS PolHistDet
ON PolHist.history_id = PolHistDet.history_id
