How to use vba to update a field based on the value of another field?

Hi,

I have a field in a table named [Function] that contains what I believe a programmer would call a string.

It looks like the following with many variations:

--2-45--
1-34----

In a db, I added three additional fields named [ ShippingPort], [RailHub], [Airport].

How could I use vba to update each of these above fields based on the values within the [Function] field? i.e. If a 1 is found, then the corresponding [ShippingPort] field would be updated to Yes/No, if a 2 is found, then the corresponding [RailHub] field would be updated to Yes/No and so on.

Keys are as follows:

1 = Shipping Port
2 = Rail Hub
4 = Airport

Ideally, I would be able to run a procedure at any time that would update all the above three mentioned fields in my table, based on the contents of the string in the field [function].

I have enclosed a db file with the table as well if this helps.

Thanks

First off, you forgot to include your attachment.  Secondly, why do you want to update the table with those values when you could just create a query that can have calculated fields based on your table field.  Updating the table with data from the table would be redundant and is considered bad practice.

Create a query instead similar to this:
SELECT [YourField], IIF([YourField] Like "*1*", "Yes","No") AS ShippingPort,  IIF([YourField] Like "*2*", "Yes","No") AS RailHub, IIF([YourField] Like "*4*", "Yes","No") AS Airport FROM YourTable

Open in new window

All you needed to do was copy and paste the code I gave you into the SQL View of a query, then revise the field and table names to match yours.  Anyway here's your revised database.
