wonderware - Wonderware Historian：查询 Runtime.Events 视图

Question

我想用 SQL 查询 Runtime.Events 视图。我尝试了以下方法：

select * from Runtime.dbo.Events给出以下错误：

OLE DB provider "INSQL" for linked server "INSQL" returned message "Event History no longer supports queries that do not provide time".

select * from Runtime.dbo.Events where EventTime >= '2018-09-01 00:00:00' and EventTime <= '2018-11-01 00:00:00'给出了这个非描述性错误：

Cannot execute the query "..." against OLE DB provider "INSQL" for linked server "INSQL".

日期格式似乎是正确的，因为当我尝试使用不同的格式时，我收到错误，指的是错误的日期格式。

如何查询此视图？

Answer 1

Perhaps you're trying to query for these events:

SELECT TOP 1000 *
FROM [A2ALMDB].[dbo].[v_EventHistory]

or these events:

SELECT * FROM Runtime.dbo.EventHistory
WHERE DateTime >= '2018-10-11'

Answer 2

由于缺乏声誉，我无法通过评论来澄清这一点，所以让我发布一个答案。可能是您的警报和事件在 A2ALMDB 数据库中。如果是这种情况，请尝试以下查询。

SELECT * FROM [A2ALMDB].[dbo].Events WHERE [EventStamp] between '2018-09-01 00:00:00' AND '2018-11-01 00:00:00'
