MDAC 2.5 SDK - ODBC Desktop Database Drivers
The name of the type (TYPE_NAME) returned in the table produced by SQLGetTypeInfo will be the name most commonly used by the data source.
SQL_ALL_EXCEPT_LIKE will be returned in the SEARCHABLE column for the Byte, Counter, Double, Single, Long, and Short data types. (The LIKE capability can be achieved by converting the value to a character using the ODBC canonical conversion functions, and then performing the comparison.)
