RE: need join help

Hi Chris,

Based on my understanding, you have two database tables named 'BTN' and
'Arcust01'. The table 'BTN' has 5 rows in it and there're 2 rows in the
table 'Arcust01' matching 2 of the 5 rows in the table 'BTN'. What you want
is to query both two tables and return all the 5 rows in the table 'BTN'
among which the 3 rows not being matched returned with nulls in the fields
from the table 'Arcust01'. If I'm off base, please feel free to let me know.

You should use left outer join to get what you want. The following is a
sample:

Dim sQry As String = "select btn.btn, arcust01.lastpay, arcust01.balance
from btn left outer join f:\chris\arcust01 arcust01 on btn.btn =
arcust01.custno"

myOleDbCommand.CommandText = sQry

Hope this helps.
If you have any question, please feel free to let me know.

Sincerely,
Linda Liu
