cheers, j.a.z.
Some fields can be of the following type too : REALHere is the complete list!
Access 2003 as the following teturntypes:
COUNTER - Autoincrement
VARCHAR - Text
LONGCHAR - Memo
INTEGER - Number
DATETIME - Date/Time
CURRENCY - Currency
BIT - TRUE/FALSE
LONGBINARY - OLE-Object
LONGCHAR - Hyperlink
DOUBLE - Double Number
BYTE - Byte Number
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.
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...
