Hi,
I'm trying to update the following a column where if part number has an option to put a '#' between the middle and concatenate the two columns together, else if the part number hasn't a option to show the part number only i.e

part_number                          option            Merged
45556            GHJ            45556#GHJ
54566                        54566
45666            UOY            45666

I've tried the follow but no luck:

Update TableA
set MERGED = '[PartNumber] & IIf(IsNull(Option),"","#" & PartNumber)'

Error Message

Disallowed implicit conversion from data type varchar to data type varbinary, table 'TableA', column 'MERGED'. Use the CONVERT function to run this query.
