TYPES vector TYPE STANDARD TABLE OF i WITH NON-UNIQUE DEFAULT KEY INITIAL SIZE 10.本示例创建内表数据类型 vector,其行包含基本类型 I 字段。注:WITH HEADER LINE只能与DATA关键字一起使用,而不能与TYPES一起使用,这也就是说,只有在分配了存储空间时才有隐藏工作区这一说,在定义内表类型时是没有的。
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...
如果你把第一行的b改为22那么wa就是第一行了,应为b第一、第二行都最小,那么就比较二级所以的C字段,看哪个最小。 使用内表KEY访问内表 类似上面 wa = itab[ KEY key col1 = ... col2 = ...]. wa = itab[ KEY key COMPONENTS col1 = ... col2 = ...]. 相当于READ TABLE WITH TABLE K...
