As the result of a query, a reference to an object of the class CL_SQL_RESULT_SET is returned in the return value RESULT_SET. The methods of this object allow access to the results set of the query. To retain the results set beyond the end of a database LUW, the input parameter ...

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...
一旦指向结果集(result set)的引用lo_result在1049行代码调用next_package方法,CDS view的前1000条数据就被赋值到了ABAP内表lr_data里: 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...
