Concatenate fields on form and write back to table

Concatenate fields on form and write back to table

Concatenate fields on form and write back to table


I seem to be beating my head against the wall on something I should know and something I know I've done before. I have a form that takes text box A and concatenates text box B to create text box C. I have the correct concatenation string showing up on the form so i know it's putting together the data right. Now, how do I take that information in the text box C and write back to the table? I currently have the record source as a query that just looks at my master table.

Would I have to add these new records to a temp table and use an update query to write these back to the master table? Isn't there an easier way?

RE: Concatenate fields on form and write back to table

Why do you want to store a value that can be calculated on the fly? This isn't typically good practice.

However, you can set the control source of text box C to the field in your table and use a little code in the after update events of txtA and txtB to set the value:

CODE --> vba

Me.txtC = Me.txtA & Me.txtB

Actually... now that you've talked it out, I'm not sure why i done it that way either. What I ended up doing was taking the data and storing it in a temp table and then append all of the records (including the concatenated field) to a master table. I know that is highly inefficient but it worked in a pinch.

I found out later than the DB requester is just dumping the data from Access to Excel anyways so I could have done the concatenation on the fly. Thanks for the tip though. It would have been much easier to do it on the fly.
