我有以下查询:
SELECT * FROM [DSPCONTENT01].[dbo].[zWMGWEEKARRIVAL]
WHERE
[ARRIVED DATE] = 'WEEKLY TOTAL' OR [ARRIVED DATE] = 'PRIOR WEEK' OR [ARRIVED DATE] = '12 WEEK AVERAGE'
显示:
有没有办法添加另一个列或从中创建另一个表,在那里添加总数?
示例:
ARRIVED DATE TOTAL
WEEKLY TOTAL 12000
PRIOR WEEK 13654
12 WEEK AVERAGE 10094

只需使用+
,但请注意NULL
s:
SELECT [ARRIVED DATE],
(coalesce(col1, 0) + coalesce(col2, 0) + coalesce(col3, 0), . . .
) as Total
FROM [DSPCONTENT01].[dbo].[zWMGWEEKARRIVAL]
WHERE [ARRIVED DATE] IN ('WEEKLY TOTAL', 'PRIOR WEEK', '12 WEEK AVERAGE');
我无法轻易阅读您的列名,但您应该包含真实姓名。

如果您希望将和作为数据库中的列,则可以添加所谓的computed column。您基本上只需添加一个查询作为列。您可以在计算列规范下的表设计器中的SSMS内执行此操作,也可以通过链接中所述的alter table语句执行此操作。
ALTER TABLE zWMGWEEKARRIVAL
ADD Total AS (Theall + TheallUC + ....rest of columns )
