速度:= > IN > BETWEEN > LIKE > NOT 【但有时SQL语句执行时,系统自动分配的先后顺序可能会导致取数更慢。 如:根据BWART和BUDAT_MKPF(建立索引)取MSEG,如果BWART用IN,BUDAT_MKPF用BT,系统可能会先根据BWART取数。这时,尽量避免对BWART使用IN,应改为BT,让BWART和BUDAT_MKPF处在同一层级的运算符上,让数据库...
ABAP/4中可以利用SQL语法创建或读取TABLE,SQL语法分为DDL(DATA DEFINE LANGUAGE)语言和DML(DATA MULTIPULATION LANGUAGE)语言,DDL语言是指数据定义语言,例如CREATE等, DML语言是数据操作语言,例如SELECT, INSERT等语句。SQL语句有OPEN SQL语句和NATIVE SQL语句。 OPEN SQL语句不是标准SQL语句,是ABAP/4语言,利用OPEN ...
在使用运算符LIKE的 SQL 条件下,“%”代表任何字符串,“_”代表单个字符。在正则表达式中,使用一整套特殊字符来定义模式。通配符的特殊功能可以使用转义字符取消 字符串中的使用 注意: COCNCA,NA比较时区分大小写,且尾部空格也在比较范围之内, CSNSCPNP比较时忽略尾部空格且不区分大小写,比较结束后,如果结果为真,...

In my point of view, if there is no actual performance gain by using the new methods, apart from some new additions like CONV which are indeed very useful, it seems to me that it will just make the code a lot more complex for other programmers, not familiar with the new methods, to...
ABAP CDS Views are great and all; however, they don't support subqueries at this time. In this post, I would like to share a workaround which functions similar to "NOT EXISTS". The requirement was to exclude material document items (MSEG) which were reverse posted; and the reversal docum...
