The CachedRowSet is the base implementation of disconnected row sets. It connects to the data source, reads data from it, disconnects with the data source and the processes the retrieved data, reconnects to the data source and writes the modifications.Creating a CachedRowSetYou can create a Cached RowSet object using the createCachedRowSet() method of the RowSetFactory.You can create a RowSetFactory object using the newfactory() method of the RowSetProvider method.Create a CachedRowSet object using the above mentioned methods as shown below −//Creating the RowSet object RowSetFactory factory = RowSetProvider.newFactory(); CachedRowSet rowSet = factory.createCachedRowSet();Connecting to the data sourceAfter creating a RowSet object you ...

To get the total number of rows when using LIMIT, use the following syntax −select SQL_CALC_FOUND_ROWS * FROM yourTableName LIMIT 0, yourLastValue;To understand the above syntax, let us create a table. The query to create a table is as follows −mysql> create table RowsUsingLimit -> ( -> Id int NOT NULL, -> Name varchar(10) -> ); Query OK, 0 rows affected (3.50 sec)Now you can insert some records in the table using insert command. The query is as follows −mysql> insert into RowsUsingLimit values(10, 'Larry'); Query OK, ... Read More

A bipartite graph is a graph in which if the graph coloring is possible using two colors i.e.; vertices in a set are colored with the same color. This is a C++ program to Check whether a graph bipartite or not using 2 color algorithm.Functions and pseudocodesBegin 1. Develop function isSafe() to check if the current color assignment is safe for vertex v, i.e. checks whether the edge exists or not. If it exists, then next check whether the color to be filled in the new vertex is already used ... Read More
