Hi,

I am having trouble finding an example of an entity bean using multiple tables.

Could someone give an example of how to implement entity bean that pulls data from multiple tables.

As an example I have 2 tables:

Table name: tblUser
Fields: username, addressId

Table: tblAddress
Fields: addressId, address

I want my entity bean to contain 2 variables: "username", "address".
Bean:username, address

Hello Adam,

Which scenario are you looking for?

1. Single Entity bean mapping to 2 tables
JBuilder 9 provides Multiple Table mapping provided you have defined 2 Entity Beans each mapped to a single table as mentioned in pt 2.

2. Two Entity Beans each mapping to a single table (usually defined with CMR)

I am still looking for answers to the same query you have and how to insert/select records from 2 tables using a Single Entity Bean.

Keep me posted if you get something valuable.

Rgds,

Seetesh
