在ABAP中,JOIN语句用于将两个或多个内表连接在一起。引用提到了使用INNER JOIN来连接内表的示例,例如:
```ABAP
SELECT A~EBELN, A~EBELP, SUM( A~MENGE ) AS MENGE_ALL
FROM EKET AS A
INNER JOIN @LT_EKPO AS B
ON A~EBELN = B~EBELN AND A~EBELP = B~EBELP
GROUP BY A~EBELN,A~EBELP
INTO TABLE @DATA(LT_EKET).
```
这个示例中,EKET和LT_EKPO是两个内表,通过INNER JOIN将它们连接在一起,连接条件是A~EBELN = B~EBELN和A~EBELP = B~EBELP。通过这个连接,可以在LT_EKET内表中获取对应的字段值。
另外,引用提到了使用FOR ALL ENTRIES IN语句连接内表的示例,例如:
```ABAP
SELECT A~EBELN, A~EBELP, A~MENGE
INTO TABLE @DATA(LT_EKET)
FROM EKET AS A
FOR ALL ENTRIES IN @LT_EKPO
WHERE EBELN EQ @LT_EKPO-EBELN AND EBELP EQ @LT_EKPO-EBELP.
```
这个示例中,同样是连接EKET和LT_EKPO两个内表,但是使用了FOR ALL ENTRIES IN语句。通过指定WHERE条件和对应的内表字段,可以根据LT_EKPO内表中的字段值来筛选EKET内表中的对应记录,并将结果存储在LT_EKET内表中。
因此,JOIN语句是用于连接内表的重要语句,在ABAP中有多种方式可以实现内表的连接操作。<em>1</em><em>2</em><em>3</em>
