Question

我有一个查询，我需要在两个单独的列中获取查询结果，因为我正在做两个单独的查询

 Select STUFF((SELECT ',' + cast(Task.ID as varchar(100))
                from dbo.TaskRepeted 
                join dbo.Task on Task.id = TaskRepeted.Taskid
            where TaskID IN (1,2,3,4,5,6,7,8,9)
            FOR XML PATH('')) ,1,1,'') as Tasks 
    
    UNION ALL 
    
     Select STUFF((SELECT ',' + cast(CoreTask.ID as varchar(100))
                from dbo.TaskRepeted 
                join dbo.CoreTask on CoreTask.id = TaskRepeted.Taskid
            where TaskID IN (1,2,3,4,5,6,7,8,9)
            FOR XML PATH('')) ,1,1,'') as CoreTasks

它仅显示一列为：任务

和两行：

第一行的数据为：3344,3,43,6,7,6,7,,34,3,443,434 第二行为空

但是我的数据应如下所示：

Tasks                               CoreTasks
3344,3,43,6,7,6,7,,34,3,443,434     0 (if null is coming, it should display me 0 else it will display the comma separated values)

如果要两列，请不要使用union：

 Select STUFF((SELECT ',' + cast(Task.ID as varchar(100))
                from dbo.TaskRepeted join
                     dbo.Task on Task.id = TaskRepeted.Taskid
            where TaskID IN (1,2,3,4,5,6,7,8,9)
            FOR XML PATH('')) ,1,1,'') as Tasks ,
        STUFF((SELECT ',' + cast(CoreTask.ID as varchar(100))
                from dbo.TaskRepeted join
                     dbo.CoreTask on CoreTask.id = TaskRepeted.Taskid
            where TaskID IN (1,2,3,4,5,6,7,8,9)
            FOR XML PATH('')) ,1,1,'') as CoreTasks

以逗号分隔获取两列的值
