Hello, I'm a relatively new user and have run into a problem which may just be a misunderstanding. I'm using the Oct2014 version, installed on Fedora 20 from the MonetDB rpm repository. When I try to query a database using inet "containment" operators like << or <<= it seems that the operators are not recognized: sql> select src,dst from raw.ids where src << inet'xxx.xxx.xxx.xxx/27'; SELECT: no such binary operator 'left_shift(inet,inet)' sql> select src,dst from raw.ids where src <<= inet'xxx.xxx.xxx.xxx/27'; syntax error, unexpected '=' in: "select src,dst from raw.ids where src <<=" Other ordinary binary inet operators seem OK: sql> select src,dst from raw.ids where src = inet'xxx.xxx.xxx.xxx'; (prints out table) sql> select src,dst from raw.ids where src < dst; (prints out table) However the documented functions do not seem to be recognized: sql> select masklen(inet'192.168.0.0/24') SELECT: no such unary operator 'masklen(inet)' sql> select netmask(inet'192.168.0.0/24') SELECT: no such unary operator 'netmask(inet)' So it seems that support for network address types is only partially available in this release. Is that normal? Do I need to rebuild from source in order to get them? Thanks! Tim
