If the row is not found, this is noted in the buffer and a fully specified WHERE clause is used to avoid a new database access in the next read. Notes When using single record buffering, any ABAP SQL statements
If a fully specified generic key is used to access an unbuffered row through ABAP SQL, an attempt is made to load the area. If the row is not found, this is noted in the buffer and the database is not accessed again the next time a row is accessed using a fully specified generic ...

ABAP 支持下列几种缓冲类型: 当使用完全缓冲(full bufferred)时,要么缓冲整个表,要么不缓冲任何记录。 当访问单个记录时,该表的整个数据/记录都会被缓冲。 缓冲是指所有记录都在缓冲表中。 完全缓冲适应于频繁读取但是极少写入的数据库表。 当使用 Generic Buffering 时,所有带有 Generic 键的记录都会被一次性缓冲。

SAP应用及ABAP开发最佳实践—Internal-Table_2内表 内表 • ABAP中的内表相当于其他程序设计语言中的二维数组,存储多行结构相同的数据 • 不同于二维数组,内表在创建后,列结构与列数是固定不变的,而行数是动态增长的 • 内表支持循环对每行数据进行操作,也支持整体操作...
