[erlang-bugs] erlang/odbc <-> ms-sql error with 'uniqueidentifiers' (aka GUIDs): ODBC_UNSUPPORTED_TYPE

[Ingela Anderton Andin]

Hi!

It seems to be a missing feature. Support for the data_type SQL_GUID is 
not implemented.
I do not think it would be all that hard to implement but will not be 
highly prioritized by Ericsson.
Maybe somebody would like to make a user-contribution?! You should start 
looking at the
funtion encode_data_type in odbcserver.c
