将两个连续的询问内容合并成一个,并更新
原标题:combine the content of two seperate queries into one and update

我希望我正确地描述这一点。 我有以下两个更新的问询,分别进行正确的工作。 我需要首先更新这个领域,并在第二个阶段使用这个领域。

这是第一个。

UPDATE Products_Joined SET TechSpecs =  var srating_  
+ Products_Joined.ProductCode +  ="  + CAST(Reviews.AverageRating AS VARCHAR) +  ";var rcount_  + Products_Joined.ProductCode +  ="  + CAST(Reviews.TotalRatings AS VARCHAR) +  ";  

FROM Products_Joined LEFT OUTER JOIN (
SELECT Reviews.ProductCode, AVG(Reviews.Rate) AS AverageRating, COUNT(Reviews.ReviewID) AS TotalRatings
FROM Reviews
GROUP BY Reviews.ProductCode
) AS Reviews ON Products_Joined.ProductCode = Reviews.ProductCode;

这是第二个。

DECLARE @OpenTag varchar(100)
SET @OpenTag =  <script type="text/javascript" language="javascript"> 

UPDATE Products_Joined
SET TechSpecs  = STUFF(CAST(TechSpecs AS VARCHAR(MAX)) ,
                   CHARINDEX(@OpenTag, CAST(TechSpecs AS VARCHAR(MAX)) ,1)  + LEN(@OpenTag),
                        CHARINDEX( </script> ,CAST(TechSpecs AS VARCHAR(MAX)) ,1)-(CHARINDEX(@OpenTag, CAST(TechSpecs AS VARCHAR(MAX)) ,1)  + LEN(@OpenTag)), 
                    *****HERE IS WHERE I WANT TO PUT THE FIELD FROM THE FIRST SQL QUERY******* )
WHERE TechSpecs LIKE  %<script type="text/javascript" language="javascript">%</script>
