SAP连接HANA数据库

既然都用HANA了，为什么还要在SAP端，连接HANA数据库，做数据库处理。。。。。

因为HANA数据库，没个用户在STADIO上建的数据库表。。。只能这个用户使用，而做Universe 设计的时候，最简单的就是直接用表。。。（但是SAPDEV这里表太多了，用起来太麻烦，所以。。。）

1.DBCO连接

DB 连接            HDB
DBMS               HDB
用户名             ZYUSER
数据库口令                                        /
连接信息           192.168.2.106:

连接限制
最佳连接           

然后SE38运行ADBC_TEST_CONNECTION，选择HDB测试连接

如果此处不通。。。呵呵哒，自己找原因

异常消息没处理。。。自己找类，自己玩。。。
