ABAP“FOR ALL ENTRIES”的Hints 优化 通常默认情况下“FOR ALL ENTRIES IN”语句会将内表每5个数据生成一个新的Where语句来执行。 可通过事务代码“RZ11”查询参数名称“rsdb/max_blocking_factor”,如下图所示。 ... 查看原文 【力荐】Select查询语句中LIKE关键词的优化方法分析 :当执行SQL时,如果有符合选择...

The for all entries creates a where clause, where all the entries in the driver table are combined with OR. If the number of entries in the driver table is larger than rsdb/max_blocking_factor, several similar SQL statements are executed to limit the length of the WHERE clause. The plus ...
WHERE f IN (itab[1]-f, itab[2]-f, ..., itab[N]-f) rsdb/max_blocking_factor This parameter specifies an upper limit for the number of entries taken in from [itab] to be processed in one statement. This means that if the internal table specified in the FOR ALL ENTRIES clause ...

b)如果prefer_in_itab_opt为1,则for all语句执行时,itab中每条数据都会转化为in的方式,即field in (itab[1]-value, itab[2]-value, itab[3]-value)。而in的速度比or快。 系统中还有一个参数叫做rsdb/max_in_blocking_factor。当itab中有1万条数据时,可能会被拆解成多个sql执行,而max_in_blocking_...
