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 findColumn() method of the ResultSet interface maps the column label to column index. Using this you can find the index of a particular column in the result set.This method accepts a String ... Read More

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

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 last() method of the ResultSet interface moves the pointer of the current (ResultSet) object to the last row, from the current position.This method returns a boolean value specifying whether the ResultSet cursor ...

Initially this cursor is positioned before first row.The insertRow() method of the ResultSet interface inserts the contents of the row into the ResultSet object (and into the table as well).rs.moveToInsertRow(); rs.updateInt("ID", id); rs.updateString("First_Name", "Ishant"); rs.updateString("Last_Name", "Sharma"); rs.updateDate("Date_Of_Birth", new Date(904694400000L)); ...

Initially this cursor is positioned before first row.The insertRow is a special row of the ResultSet in JDBC, it is associated with the updatable ResultSet objects. In it you can construct a new Row calling the UpdateXXX() ... Read More

The getMaxIndexLength() method of the DatabaseMetaData interface is used to find out the maximum number of bytes that the underlying database allows for an index.This method returns an integer value, representing the maximum number of byes allowed in an index. If this value is 0 it indicates that there is no limit or, limit is unknown.To get the DatabaseMetaData object −Make sure your database is up and running.Register the driver using the registerDriver() method of the DriverManager class. Pass an object of the driver class corresponding to the underlying database.Get the connection object using the getConnection() method of the DriverManager ... Read More
