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...
二级连接 (Secondary Connection) 定义:在表 DBCON 内维护,键值 CON_NAME 作为连接名,区分大小写。 限制:目标数据库必须受 SAP 支持;需部署相应 DBSL(Database Shared Library) 与客户端库。 用法:在任何 SQL 技术栈中使用同名标识符即可,首次调用自动打开连接;最多 15 条二级/服务连接同时存在于同一工作进程中...
