concatenate

[JH]

Access 2003
I have a table with three fields. All the rows in column A and C have data
in them, however column B may or may not have data. I need to create a query
to concatenate the fields in column D but maintain the blank data in field
B. For example
A B c d
abcd efgh ijkl abcdefghijkl
abcd ijkl abcd ijkl
Any ideas?
Your help is much appreciated. Thanks

Since there is no data if field B there is nothing to maintain. Perhaps you
mean that you want to insert some spaces or underscore characters if field B
is Null
