odbc_field_type — Datatype of a field
$result_id
, int $field_number
) : stringGets the SQL type of the field referenced by number in the given result identifier.
result_idThe result identifier.
field_numberThe field number. Field numbering starts at 1.
Returns the field type as a string, or FALSE on error.
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.
