返回零而不是值

Question

Issue: PassedPercent returns 0 but there should be a number (I can confirm in all cases @Started and @Passed have numerical values). The same formula worked correctly on the .aspx page but I'm converted it to an SQL query.

Code:

USE DATABASE

DECLARE @i INT = 0 
DECLARE @ModuleID  bigint
DECLARE @Started   bigint
DECLARE @Completed  bigint
DECLARE @Passed  bigint

DECLARE merge_cursor CURSOR FAST_FORWARD FOR SELECT [ModuleID] FROM dbo.[TblModules] 
--ORDER BY [ModuleID]
OPEN merge_cursor

FETCH NEXT FROM merge_cursor INTO @ModuleID

WHILE @@FETCH_STATUS = 0
BEGIN

    SET @Started =  (Select Count(ID) FROM [TblResults] WHERE [ModuleID] = @ModuleID) 
    SET @Completed = (Select Count(ID) FROM [TblResults] WHERE [ModuleID] = @ModuleID and ModuleDatecomplete <> '')
    SET @Passed = (Select Count(ID) FROM [TblResults] WHERE [ModuleID] = @ModuleID and Pass = 'Yes')

    UPDATE [TblModules]  SET [Started] = @Started,[Completed] = @Completed,[Passed] = @Passed,[PassedPercent] = ((@Passed / @Started) * 100)
    WHERE [ModuleID] = @ModuleID     

    FETCH NEXT FROM merge_cursor INTO @ModuleID 
END

CLOSE merge_cursor
DEALLOCATE merge_cursor 

Answer 1

An int / int will return an int (in this case zero)

Try

 ,[PassedPercent] = (@Passed *100.0) / @Started
