MatrixOne 的 JDBC 功能支持列表
使用 JDBC 开发应用,MatrixOne 支持以下类和对象:
1. Connection(类):获取数据库连接对象
类中的方法
-
获取执行 Sql 对象 Statement
- Statement createStatement();
- Statement prepareStatement(String sql);
-
管理事务
- 开启事务:setAutoCommit(boolean autoCommit):调用该方法设置参数为 false,即开启事务
- 提交事务:void commit()
- 回滚事务:void rollback()
