#1

I need help writing a query

I have 2 table with below structure
Table : RMmaster
RMID | RMname|

Table : Relationship
ID | RelationshipName | RM1 | RM2 | RM3 |

(RM1, RM2, RM3 map to RMID values from RMmaster table.)

I want to write a query to show all the records from RMmaster table which do not exist in RM1 or RM2 or RM3 fields of the Relationship table.

Thanks for your help
