/**
* A ResultSet provides access to a table of data generated by executing a Statement. The table rows are retrieved in sequence. Within a row its column
* values can be accessed in any order.
*
* <P>
* A ResultSet maintains a cursor pointing to its current row of data. Initially the cursor is positioned before the first row. The 'next' method moves the
* cursor to the next row.
* </p>
*
* <P>
* The getXXX methods retrieve column values for the current row. You can retrieve values either using the index number of the column, or by using the name of
* the column. In general using the column index will be more efficient. Columns are numbered from 1.
* </p>
*
* <P>
* For maximum portability, ResultSet columns within each row should be read in left-to-right order and each column should be read only once.
* </p>
*
* <P>
* For the getXXX methods, the JDBC driver attempts to convert the underlying data to the specified Java type and returns a suitable Java value. See the JDBC
* specification for allowable mappings from SQL types to Java types with the ResultSet getXXX methods.
* </p>
*
* <P>
* Column names used as input to getXXX methods are case insenstive. When performing a getXXX using a column name, if several columns have the same name, then
* the value of the first matching column will be returned. The column name option is designed to be used when column names are used in the SQL Query. For
* columns that are NOT explicitly named in the query, it is best to use column numbers. If column names were used there is no way for the programmer to
* guarentee that they actually refer to the intended columns.
* </p>
*
* <P>
* A ResultSet is automatically closed by the Statement that generated it when that Statement is closed, re-executed, or is used to retrieve the next result
* from a sequence of multiple results.
* </p>
*
* <P>
* The number, types and properties of a ResultSet's columns are provided by the ResultSetMetaData object returned by the getMetaData method.
* </p>
