Hi Friends, I am running Racktables version 0.19.3 on Centos 5.5 32-bit with Mysql 5.0.x. I am trying to write a sql query to fetch the details like Object Name, Rack Name, Rack Row Name, IPAddress etc.. Query is working fine except I am not able to get the proper IPAddress(in dotted form) from the IPv4Allocation table. Mysql Query to fetch the data: select distinct(a.name) as Server_Name, a.asset_no as Asset_Number, c.nameas Rack_Name, d.name as DataCenter_Name, e.ip as IPAddress from RackObject a, RackSpace b, Rack c, RackRow d, IPv4Allocation e where a.id=b.obj ect_id and b.rack_id=c.id and c.row_id=d.id and a.id=e.object_id group by Server_Name; Output: testmachine3133Rack1Data Center12886730305 But the what is need is testmachin3133Rack1Data Center1172.16.x.x What sql query should I run to get the IPAddress in the CIDR or in dotted form. I tried the below query(taken from the racktables database.php file) but this script is also not running and returning error. SELECT id FROM IPv4Network AS subt WHERE IPv4Network.ip & (4294967295 >> (32 - subt.mask)) << (32 - subt.mask) = subt.ip and subt.mask < IPv4Network.mask ORDER BY subt.mask DESC limit 1 SELECT id FROM IPv4Network AS subt WHERE IPv4Network.ip & (4294967295 >> (32 - subt.mask)) << (32 - subt.mask) = subt.ip and subt.mask < IPv4Network.mask ORDER BY subt.mask DESC limit 1 -> ; ERROR 1054 (42S22): Unknown column 'IPv4Network.ip' in 'where clause' Please share the correct sql query to get the proper ipaddress.
