MetaColumns($table, $toupper=true)

这个函数到底怎么用的啊
如何才能得到表中具体每个字段的类型

Returns an array of ADOFieldObject's, one field object for every column of $table. A field object is a class instance with (name, type, max_length) defined. Currently Sybase does not recognise date types, and ADO cannot identify the correct data type (so we default to varchar).

The $toupper parameter determines whether we uppercase the table name (required for some databases).

For schema support, pass in the $table parameter, "$schema.$tablename". This is only supported for selected databases.

不理解上面讲的意思:crying:
