An important thing to note is that using
fbsql_fetch_assoc() is NOT significantly
slower than using fbsql_fetch_row(), while it
provides a significant added value.
Returns an associative array that corresponds to the fetched row, or
FALSE if there are no more rows.
If two or more columns of the result have the same field names, the last
column will take precedence. To access the other column(s) of the same
name, you must use fbsql_fetch_array() and have it
return the numeric indices as well.
