( resource stmt [, int row_number] )
Returns an object in which each property represents a column returned in
the row fetched from a result set.
Returns an object representing a single row in the result set. The
properties of the object map to the names of the columns in the result set.
The IBM DB2, Cloudscape, and Apache Derby database servers typically fold
column names to upper-case, so the object properties will reflect that case.
If your SELECT statement calls a scalar function to modify the value
of a column, the database servers return the column number as the name of
the column in the result set. If you prefer a more descriptive column name
and object property, you can use the AS clause to assign a name to the
column in the result set.
Returns FALSE if no row was retrieved.
