在WonderWare中使用子查询来选择所有标签

Question

我试图从数据库中的所有标签上的WonderWare历史数据库中获取数据。已经有一个包含所有标签的表格，所以我想用一个子查询来选择所有的标签名称。这个子查询出现错误w.r.t。

我的SQL语句：

/****** 

I want to be able to select: 
    - all columns 
    - for all tags <-- I'm getting an error here, trying to use a subquery 
    - between two time stamps 
    - at a specified resolution 

******/ 

SELECT * 
FROM 
    Runtime.[dbo].AnalogHistory 
WHERE 
    TagName IN (
     SELECT DISTINCT TagName 
     FROM 
      Runtime.dbo.Tag 
    ) 
AND 
    DateTime >= '2016-01-01 00:00' 
AND 
    DateTime < '2016-01-01 00:30' 
AND 
    wwResolution = 5000 
AND 
    wwRetrievalMode = 'Average' 
AND 
    wwTimeStampRule = 'Start' 

我收到的错误是：

OLE DB provider "INSQL" for linked server "INSQL" returned message "History queries must contain at least one valid tagname". 

我的猜测是指没有被正确地执行它。

我使用OPENQUERY也试过，但后来我得到相关子查询无法辨别关于标签表“模式”信息其他错误：

OLE DB provider "INSQL" for linked server "INSQL" returned message "Failed to retrieve schema information for object 'Tag'". 

这是摘录更改：

TagName IN (SELECT * FROM OPENQUERY(INSQL, 
    'SELECT DISTINCT TagName 
    FROM 
     Runtime.dbo.Tag') 
) 

Answer 1

尝试：

SELECT DISTINCT aa.TagName FROM (
SELECT DateTime, TagName, Value 
FROM History 
WHERE DateTime >= '2016-01-01 00:00' 
AND DateTime <= '2016-01-01 00:30' 
AND wwResolution = 5000 
AND wwRetrievalMode = 'Average' 
AND wwTimeStampRule = 'Start' 
) aa 

Answer 2

Historian服务器是不是一个正常的SQL Server数据库。这是从INSQL链接服务器获取数据的历史视图。 INSQL有一些特殊的规则，记录在HistorianConcepts.pdf中。

SELECT 
    * 
FROM 
    Runtime.dbo.Tag t 
INNER REMOTE JOIN 
    Runtime.dbo.AnalogHistory h 
ON 
    t.TagName = h.TagName 
WHERE 
    DateTime >= '2016-01-01 00:00' 
AND 
    DateTime < '2016-01-01 00:30' 
AND 
    wwResolution = 5000 
AND 
    wwRetrievalMode = 'Average' 
AND 
    wwTimeStampRule = 'Start'
