When 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 are used , there is
no way for the programmer to guarantee that they actually refer to
the intended columns .

against the older specification may return a special invalid value , such
as a negative number , zero , or a number greater than the number of
columns .
