Docs: note overlap of datatype IDs #141

Closed bpintea closed 5 years ago

bpintea commented 5 years ago

The IP datatype uses currently the same ID as text/keyword. This prevents a client from explicitly specifying a value as IP and not just text. Note this limitation, should any developer actually consider using the ODBC API over REST. Same for geo types, if they will re-use text/keyword ID.

This is an SQL implementation issue, not necessarily ODBC specific. On the low chance that the driver would be used as client for a developing application, the developer would need to check server's data types anyways, in which case the overlap would become relevant there.
