通过NATIVE SQL 访问外部数据库步骤 打开连接 执行SQL命令 关闭连接 示例代码见文末 01 读取多条记录的方式 游标方式 图一 非游标方式 图二 非游标方式其实隐式使用了游标.性能比游标方式要差.数据量小的时候看不出来. 大量数据读取就能看出二者的性能差异了. ...
这种不采用ABAP OPEN SQL,而用CL_SQL_STATEMENT,CL_SQL_CONNECTION等系列工具类的数据库访问方式,称为ADBC - ABAP Database Connectivity. ADBC是一套API的集合,能允许ABAP开发人员使用ABAP面向对象编程的方式,同ABAP服务器的原生SQL接口进行交互。 Jerry之前的文章集合 Jerry的ABAP, Java和JavaScript乱炖,里面有一篇...
