Hello all,

I am trying to do the following.   I have a table called Customer and then I have a table called CustomerGroup 1 to Many to Customer.   The fields for example are as follows:

Table:   Customer
Fields:  CustId,  CustName, CustAddress

Table: CustomerGroup
Fields:  CustId, GroupName

I want to get all the fields from table Customer then I want a comma seperated string of all the GroupNames from CustomerGroup stripped off end comma.   How can I do this?  Sample data:

Customer
CustID 1
CustName ABC
CustAddress 12 Water St

CustomerGroup
CustID 1
GroupName A

CustID 2
GroupName B

CustID 3
GroupName C

Record would return
1,  ABC,  12 Water St, 'A,B,C'
