Do you in fact have a schema dbo?
If so can you access the schema and table using some other method, for instance 
using psql?

Hi Rehan,

Whilst I'm not sure what you exactly mean with '...., while this is working perfectly fine in sql,..',
it's kind of odd that you get result when you execute the sql.
I'd suggest looking at your search_path (show search_path), which normally resolves to 'user', 'public';

If you do have a schema dbo, you could change the search_path as follows:
alter user <your user> set search_path = '$user','public','dbo';

from  dbo.kbsites a inner join dbo.kbsites b on a.chr=b.chr

inner join dbo.kbdetails kbd on a.kbid=kbd.kbid

where kbd.active='1' ;

i am getting this error , how can i fix this.

First, I assume you are converting your view from SQL Server, not from SQL.
SQL Server is RDBMS, while SQL is a language being used by multiple RDBMSs including PostgreSQL.

Second, there is no "standard" dbo ("database owner") role in Postgres.
Before converting from one RDBMS to another you need to do some basic (at least) documentation reading on "target"
RDBMS(in this case - PostgreSQL). 
Otherwise, you will stumble on every step.
