Question

我有下面的表格。我想总结部分列并在最后一条记录后写下总数。如何在sql查询中指定总数和结果。

                   Model  parts

                  Model1      4 
                  Model2      2
                  Model3      6
                  Model4      5
                  Model5      7
                   Total     24

Answer 1

您可以使用UNION查询来显示详细数据，并附加一行来显示摘要。

SELECT 0 AS order_by, Model, parts
FROM YourTable
UNION ALL
SELECT 1 AS order_by, 'Total' AS Model, Sum(parts) AS parts
FROM YourTable
ORDER BY 1, 2;

Answer 2

试试这个query

SELECT  models, parts
FROM    your_table
UNION
SELECT  'Total' AS models, SUM(parts) AS parts from your_table

SQL查询以获取访问表中最后一行中所有列值的总和
