read之前一定要排序,按照read的KEY字段进行排序,否则就可能取不到。 READ 不加BINARY SEARCH的取数逻辑, 其实是取第一笔数据
ABAP READ TABLE使用BINARY SEARCH如题,read table使用binary search,with key有多个字段的时候,寻找数据的内部逻辑是怎样的比如有内表(按A,B已排好序)T_DATAA B C1 1 11 2 22 1 32 2 42 3 53 1 63 2 73 3 8现在用如下语句查找READ TABLE T_DATA INTO W_DATA WITH KEY A='2' B = '3' BINA...
在做二分查找之前，需要先对内表以查找的字段顺序进行升序排序，也就是说，在你的例子中用二分查找之前要对内表按A、B的顺序进行排序，即 SORT T_DATA[] BY A B ASCENDING.否则不一定能查找到正确的确结果
abap read table 二分法abap read table二分法 ABAP中READ TABLE语句使用顺序查找数据表,这会降低处理速度,而使用BINARY SEARCH理论上可以减少一半的运行时间。在使用binary search之前必须首先将内表排序,否则有可能数据为空。因为二分查找反复将查找区间对半划分,如果要查找的值小于查找区间的中间位置的数据项值,则查找...
