Java / JDBC
What is JDBC ResultSet?
JDBC ResultSet object is similar to a table of data representing a database result set, which is generated by executing a statement that queries the database.
ResultSet object maintains a cursor that points to the current row, initially points to the first row. Calling next() on the result set moves the cursor to next row and returns false when the last row is already reached.
A ResultSet object is automatically closed when the Statement object that generated it is closed, re-executed.
A ResultSet is readable only and the cursor moves only forward by default. It is also possible to create scrollable and updateable ResultSet. We can use ResultSet getter methods with column name or index starting from 1 to retrieve the column data.
