When we execute certain SQL queries (SELECT query in general) they return tabular data.The java.sql.ResultSet interface represents such tabular data returned by the SQL statements.i.e. the ResultSet object holds the tabular data returned by the methods that execute the statements which quires the database (executeQuery() method of the Statement interface in general).The ResultSet object has a cursor/pointer which points to the current row. Initially this cursor is positioned before first row.The afterLast() method of the ResultSet interface moves the pointer/cursor of the current ResultSet object to next position of the last row.rs.afterLast();Let us create a table with name MyPlayers in MySQL ...

In JDBC (Java Database Connectivity), the ResultSet interface represents the result set of a database query in Java. One of the important methods provided by ResultSet is getType(), which returns the type of the ResultSet object. Result getType() method The getType() method is used to determine the type of cursor and its behavior when scrolling through the result set.Syntax of getType() int resultSet_Type = rs.getType(); This method returns an integer value that corresponds to one of the ResultSet type constants. These constants indicate the type of cursor used by the ResultSet: ResultSet.TYPE_FORWARD_ONLY (value: 1003): This ... Read More
