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
READ TABLE TBA1 INTO INTO LS_TAB1 WITH KEY ID = '01' NAME = 'ZS' BINARY SEARCH. 如果TAB1内表是根据ZFIT001自建表定义的,而ZFIT001-ID字段长度定义为了字符串三位,那么可能由于数据导入的过程中存在‘01’后面多了一个空格,从而导致获取不到数据的情况。 补充READ TABLE的使用方式: 通过主键查找(WI...
READ TABLE的语法看似简洁,实则蕴含着丰富的功能选项,其基本形式如下: <itab>:这无疑是整个语句的核心操作对象,即我们所要读取数据的内表。内表可以类比为一个临时的小型数据库表,在程序运行过程中承载着业务数据。它能够通过多种方式被填充,像日常开发中常用的APPEND语句,将一条条记录有序地纳入其中。 <wa>:工...
Now, I am sorting the above internal table as follows: sort itab by A B C descnding. Now, I am writing the read stmt as follows: read table itab into wa_itab with key A = var1 B = var2 C = car3 Binary Search. But, the read fails in most of the cases even though the...
特点:已经按关键字排序好。排序表自带BINARY SEARCH功能。 区别:排序表定义关键字时,可使用WITH UNIQUE语句;而标准表只能使用WITH NO-UNIQUE语句。 (4)哈希表 特点:没有顺次索引,只能用哈希值计算出的key值进行检索,一定要设为Unique形式。
