result

由 fbsql_query() 或 fbsql_db_query() 返回的结果标识符。

row

field

Can be the field's offset, or the field's name, or the field's table dot field's name (tablename.fieldname).

If the column name has been aliased ('select foo as bar from...'), use the alias instead of the column name.

Note:

Specifying a numeric offset for the field argument is much quicker than specifying a fieldname or tablename.fieldname argument.
