在 ABAP 中,你可以使用 ORDER BY 子句对数据库表进行排序。ORDER BY 子句用于按照一个或多个字段对结果集进行排序。
以下是一个示例:
```
SELECT * FROM your_table
ORDER BY field1 ASCENDING, field2 DESCENDING.
```
在上面的示例中,your_table 是要排序的数据库表,field1 和 field2 是要按照其进行排序的字段。ASCENDING 和 DESCENDING 用于指定升序或降序排序。
你可以根据自己的需求在 ORDER BY 子句中指定多个排序字段,并且可以根据需要选择升序或降序排序。

abap select中order by
在ABAP的SELECT语句中,可以使用ORDER BY子句对结果进行排序。下面是一个示例:
```abap
SELECT * FROM zflight
WHERE airln = 'LF' AND fligh = '222'
ORDER BY airln ASCENDING, fligh DESCENDING.
```
上述代码中,我们使用了ORDER BY子句对zflight表中的数据进行排序。airln列按升序排列,fligh列按降序排列。
abap sort by
ABAP provides the SORT statement to sort internal tables. The basic syntax for sorting an internal table in ABAP is:
```
SORT <internal table>
[BY <key field> {ASC | DESC}]
[USING <comparison function>].
```
Where:
- `<internal table>` is the name of the internal table to be sorted.
- `<key field>` is the name of the field used as the sort key.
- `ASC` or `DESC` is the order of sorting (ascending or descending).
- `<comparison function>` is an optional parameter used to specify a custom comparison function for sorting.
Example usage:
```
DATA: itab TYPE STANDARD TABLE OF mara WITH KEY matnr.
* Sort the internal table by material number field in ascending order
SORT itab BY matnr ASCENDING.
* Sort the internal table by material description field in descending order
SORT itab BY maktx DESCENDING.
* Sort the internal table using a custom comparison function
SORT itab USING compare_function.
```
