为了获得最大的可移植性,应按从左到右的顺序读取每行中的结果集列,并且每列应仅读取一次。 对于getter 方法,JDBC 驱动程序尝试将底层数据转换为 getter 方法中指定的 Java 类型并返回合适的 Java 值。 JDBC 规范有一个表,显示了从 SQL 类型到可由ResultSet getter 方法使用的 Java 类型的允许映射。 用作gette...

The IN clause can be used with a result set in Java by dynamically generating the SQL query. Here's an example: First, you need to retrieve the result set in Java using JDBC (Java Database Connectivity). Iterate through the result set and store the values of the desired column in a ...
The RowSet interface extends the standard java.sql.ResultSet interface. A RowSet object may make a connection with a data source and maintain that connection throughout its life cycle, in which case it is called a connected rowset. A rowset may also make a connection with a data source,...
