ODBC Driver Limitations

ODBC is based on SQL and as such, even if an operation is supported by Superbase, that does not mean that it is supported by SQL. One major difference between Superbase and the ODBC driver is that Superbase allows updating of files which do not possess a unique key. ODBC does not support this and as such will return an error 901 if an attempt is made to update a record in a file that does not have at least one unique index.
