1.CL_SQL_CONNECTION=>GET_CONNECTION进行数据库连接; 2.根据获取的数据库连接创建对象CL_SQL_STATEMENT; 3.组合NATIVE SQL语句; 4.执行NATIVE SQL语句; 5.执行NATIVE SQL语句; 6.读取下一批量数据到内表; 7.关闭查询并释放资源,使用CL_SQL_RESULT_SET method CLOSE()

通过使用CL_SQL_CONNECTION、CL_SQL_STATEMENT和CL_SQL_RESULT_SET类，实现对HANA数据库的查询和操作。具体步骤包括：创建SQL环境引用和SQL结果集引用，为后续的SQL语句执行和数据库操作提供必要的环境准备。执行SQL查询，并获取查询结果。使用定义好的SQL语句SELECT * FROM ZLYTEST01，从数据库表中选取所有记录。获取...

CL_SQL_STATEMENT - Execution of SQL Statements CL_SQL_PREPARED_STATEMENT - Prepared SQL Statements CL_SQL_CONNECTION - Administration of Database Connections CX_SQL_EXCEPTION - Exception Class 原生SQL接口API可以在ABAP里执行动态的原生SQL操作,解决用户一些非常特殊的操作需求。
Hi All, The class CL_SQL_CONNECTION Provides a static method GET_CONNECTION which if sent a con_name as +R/3 +* will give connection to R/3 DB. Can I use this connection
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...
