使用SQL Server UNION ALL时，可以合并列吗？

Question

I have two tables in SQL Server.

• Table 1: JBIN : A List of ALL invoices.
• Table 2: ARTH : List of ALL invoices that are approved.

I have created a query which displays information on the number of days that an invoice is overdue by.

The results table looks like this:

+-----------------------+--------------+--------------+------+
|     OverdueRange      | OverdueCount | Total Amount | INVO |
+-----------------------+--------------+--------------+------+
| Due in 0-7 days       |            1 | 180215.61    |   -1 |
| Due in 31-45 days     |            1 | 153356.10    |  -32 |
| Overdue by 46+ days   |            1 | 125167.34    |   47 |
| Due in 0-7 days       |           25 | 2708613.25   |   -1 |
| Due in 31-45 days     |            3 | 62312.51     |  -32 |
| Overdue by 15-30 days |           12 | 295140.15    |   16 |
| Overdue by 1-7 days   |            1 | 111070.25    |    2 |
| Overdue by 31-45 days |            1 | 2150.50      |   32 |
| Overdue by 46+ days   |            8 | 546907.75    |   47 |
| Overdue by 8-14 days  |            1 | 156985.68    |    9 |
+-----------------------+--------------+--------------+------+

In this query, I have a UNION ALL statement.

The first three rows of the table is from JBIN whereas the rest are from ARTH .

Is it possible, when using UNION ALL to combine the data. For example, instead of having two rows called "Due in 0-7 days, I have ONE single row which SUMS the OverdueCount and Total Amount fields.

EG

Instead of this:

+-----------------+--------------+--------------+------+
|  OverdueRange   | OverdueCount | Total Amount | INVO |
+-----------------+--------------+--------------+------+
| Due in 0-7 days |            1 | 180215.61    |   -1 |
| Due in 0-7 days |           25 | 2708613.25   |   -1 |
+-----------------+--------------+--------------+------+

I want this:

+-----------------+--------------+--------------+------+
|  OverdueRange   | OverdueCount | Total Amount | INVO |
+-----------------+--------------+--------------+------+
| Due in 0-7 days |           26 | 2888828.86   |   -1 |
+-----------------+--------------+--------------+------+

FYI:

This is my query:

Answer 1

You can create a derived table from your union all query. Something like this:

select somefields, sum(something) thesum
from (
union all query goes here
) derivedTable
group by somefields
