odbc_field_type seems to return the data type of the database backend, not the data types from ODBC documentation.

Example: With my Oracle backend I get data types like "CLOB" and "VARCHAR2" while ODBC only knows SQL_LONGVARCHAR for long character data...

Quick note: as noted below, MS Access type AutoNumber comes across as type COUNTER. What I didn't see mentioned is that PHP interprets type COUNTER as a string, not an integer.

More annoying than anything else, in my particular case; but I'd guess it could bite somebody, somewhere.
