sql - 在 SQL 表和 Wonderware Historian 之间插入数据

Question

我正在尝试从 Wonderware Historian 获取值，以便在 Report Builder 中读取。我通过 Historian Client Query 获得了下面的 SQL 代码，但此代码直接从 SQL 视图中进行选择。

SET NOCOUNT ON
DECLARE @StartDate DateTime
DECLARE @EndDate DateTime
SET @StartDate = DateAdd(mi,-5,GetDate())
SET @EndDate = GetDate()
SET NOCOUNT OFF
SELECT StateSummaryHistory.TagName, StartDateTime, EndDateTime, Value, vValue
 FROM StateSummaryHistory
 WHERE StateSummaryHistory.TagName IN ('VTIS01_FT04', 'VTIS01_TT344')
 AND wwVersion = 'Latest'
 AND wwRetrievalMode = 'Cyclic'
 AND wwCycleCount = 1
 AND StartDateTime >= @StartDate
 AND EndDateTime <= @EndDate

我需要在已经创建的表中插入数据，以便我可以为报表生成器进行选择，下面是我试图在表中插入的代码：

 INSERT INTO x_TagsDescr
 SELECT StateSummaryHistory.TagName, StartDateTime, EndDateTime, Value, vValue
 FROM StateSummaryHistory
 WHERE StateSummaryHistory.TagName IN ('VTIS01_FT04', 'VTIS01_TT344')

返回以下错误：

列名或提供的值的数量与表定义不匹配。

x_TagsDescr 是我要插入的表。

有人可以帮我吗？

插入时提及列名以避免此错误是一个好习惯：

 INSERT INTO x_TagsDescr (<list of column names that match columns in your select>)
 SELECT StateSummaryHistory.TagName, StartDateTime, EndDateTime, Value, vValue
 FROM StateSummaryHistory
 WHERE StateSummaryHistory.TagName IN ('VTIS01_FT04', 'VTIS01_TT344')
