Question

我有下表＆amp;数据

表名= MyTable

Description | Partition     | Total
------------|---------------|--------------
CASH        | Reconciled    | 25
CASH        | Adjustm       | 50
CASH        | Balanc        | 120
LOANS       | Adjustm       | 44
LOANS       | Balanc        | 32
CARDS       | Adjustm       | 81
CARDS       | Balanc        | 67
MTG         | Adjustm       | 14
MTG         | Balanc        | 92

要求很简单 - 它是从表中直接选择的，但对于每个唯一的描述，我需要总结所有分区的总数，以便用户看到

Description | Partition     | Total
------------|---------------|--------------
CASH        | TOTAL         | 195   <
CASH        | Reconciled    | 25
CASH        | Adjustm       | 50
CASH        | Balanc        | 120
LOANS       | TOTAL         | 76    <
LOANS       | Adjustm       | 44
LOANS       | Balanc        | 32
CARDS       | TOTAL         | 148   <
CARDS       | Adjustm       | 81
CARDS       | Balanc        | 67
MTG         | TOTAL         | 106   <
MTG         | Adjustm       | 14
MTG         | Balanc        | 92

这是一个存储过程我写作 - 我没有选择将其拉入MT来执行此操作所以我需要在存储过程的主体中执行它。我是在寻找一些Loop或Cursor来提供我需要的卷起，还是有另外一个明显而简单的解决方案，我只是没有看到？除了卷起之外，它还是一个直接的

select * from MyTable

数据库是Sybase。

您可以使用GROUP BY子句的GROUPING SETS扩展名来执行此操作：

SELECT  Description, 
        COALESCE(Parition, 'Total') AS Partition,
        SUM(Total) AS Total
FROM    MyTable
GROUP BY GROUPING SETS ((Description, Partition), (Description));

或者您可以使用：

SELECT  Description, 
        COALESCE(Parition, 'Total') AS Partition,
        SUM(Total) AS Total
FROM    MyTable
GROUP BY ROLLUP (Description, Partition);

如果没有ROLLUP，您可以使用UNION ALL：

执行此操作

SELECT  Description, 
        Parition,
        Total
FROM    MyTable
UNION ALL
SELECT  Description, 
        'Total' AS Partition,
        SUM(Total) AS Total
FROM    MyTable
GROUP BY Description;
