Hi Experts -

I'm trying to update a field in a table with the correct view; that is to show all Part Numbers in one field. If you look at my sample2 database; I have a field called PartNumber and one called PartNumber2 I would like both of these numbers in the same field named NewPartNumber in the same table.

Should I use an Update or Append query for this?

Thanks in Advance,
GeneBat

use an update query

update tablename
set [NewPartNumber]=[partnumber1] & [partnumber2]

how exactly do you want to show the newPartnumber?

I forgot to write this; I don't want the RBB_Vendor text in the new field just numbers only.

here's a sample result. if you run the update query it put's everything in the field and not just the numbers only.

Darn, the real data could have a alpha and numeric in the PartNumber and PartNumber2 field see sample2.

Sorry about this Cap1?

Generally, it is better to do this kind of thing in a query, because if you write the concatenated value to a field in a table, and one of the components changes, the concatenated value will be incorrect.

What we're doing is correct it's just the the database field PartNumber could have a number that looks like this 13J13 so; isnumeric would not work.

PartNumber          PartNumber2     NewPartNumber
13J13                                                13J13
RRB_Vendor           14R14                 14R14
15T15                                                15T15

Like the example above.
Thanks in advance.

so basically we will disregard the values "RBB_Vendor" from PartNumber



UPDATE sample SET sample.NewPartNumber = IIF([PartNumber] Not Like "RBB_Vendor",[PartNumber] & [PartNumber2],[PartNumber2]);


are there any other values aside from "RBB_Vendor" that must be disregarded?
