Question

I have the following sql statement and I want to update a field on the rows returned from the select statement. Is this possible with my select? The things I have tried are not giving me the desired results:

SELECT 
Flows_Flows.FlowID, 
Flows_Flows.Active, 
Flows_Flows.BeatID,
Flows_Flows.FlowTitle, 
Flows_Flows.FlowFileName, 
Flows_Flows.FlowFilePath, 
Flows_Users.UserName, 
Flows_Users.DisplayName, 
Flows_Users.ImageName,
Flows_Flows.Created, 
SUM(CASE WHEN [Like] = 1 THEN 1 ELSE 0 END) AS Likes,  
SUM(CASE WHEN [Dislike] = 1 THEN 1 ELSE 0 END) AS Dislikes 
FROM Flows_Flows 
INNER JOIN Flows_Users ON Flows_Users.UserID = Flows_Flows.UserID 
LEFT JOIN Flows_Flows_Likes_Dislikes ON          
Flows_Flows.FlowID=Flows_Flows_Likes_Dislikes.FlowID 
WHERE Flows_Flows.Active = '1' AND Flows_Flows.Created < DATEADD(day, -60, GETDATE())
Group By Flows_Flows.FlowID, Flows_Flows.Active, Flows_Flows.BeatID, 
Flows_Flows.FlowTitle, Flows_Flows.FlowFileName,  Flows_Flows.FlowFilePath,        
Flows_Users.UserName, Flows_Users.DisplayName, Flows_Users.ImageName,     
Flows_Flows.Created 
Having SUM(CASE WHEN [Like] = 1 THEN 1 ELSE 0 END) = '0' AND SUM(CASE WHEN [Dislike] = 1              
THEN 1 ELSE 0 END) >= '0'

This select statement returns exactly what I need but I want to change the Active field from 1 to 0.

yes – the general structure might be like this: (note you don’t declare your primary key)

UPDATE mytable
set myCol = 1
where myPrimaryKey in (
select myPrimaryKey from mytable where interesting bits happen here )
