I have two tables Customer and CustomerPhone. Customer usually has multiple phone numbers, so when i run select statement on customer 101, i will get multiple records due to the multiple phone numbers.

alt text

As you see below all the "Phone" and "Fax" field belongs to CustomerPhone table. These are considered as two records in the CustomerPhone table whereas the rest of fields relate to Customer table which is a single record.

What should i do to fill Phone and Fax field in this case? Should i run select statement on CustomerPhone first and then run select statement on Customer?

The dynamic type in C# 4.0 is a welcome addition to the language.
