Resize a Field in an  Access 2.0 Table (Error 3219)

Posted on 2001-07-18

Hello Experts:

I have a MS-Access 2.0 Database. There is a table "Customers" and a field "Description" of type text.

Now i have to resize the field from 10 to 20 characters (using vb6).

I can't execute:

MyTDef.Fields("Description").Properties("Size").Value=20

because of Error 3219.

Please don't suggest:

1. Add a new field to the fields-collection with the desired properties (and a different field name, say 'NewField')
2. Copy all data from 'Description' to 'NewField'
3. Remove 'Description' from 'Customers'
4. Rename 'NewField' to 'Description'

or something like that, because i don't want to copy any data (there are a lot of records in 'customers').

Thanks in advance :-)

I take it that you do not have Access 2.0 available, so that you could simple change the design of the table in the MDB directly?

As far as I am aware, there is NO way to ALTER the size of an existing column via the ALTER TABLE Action query in Access SQL.

JET SQL(DAO) only supports ADD COLUMN, DROP COLUMN--you cannot change the size of an existing column, nor can you change the name of an Existing Column.

Your only choice would be : Use Access 2.0 and make the requested change directly through the Database Design interface in Access 2.0

Arthur, ty for the reply.

Yes i have Access available, but our customers have not.
I have to write a tool that has to update their databases.
So i have to initiate all jobs from vb.

Is there a way creating remote a macro in the database that can do the job ?

I don't know the DoCmd - syntaxes. Further, there may be a way doing the job via OLE.

Let's wait a day or so. If your comment still remains the best, you get the points.

You may not like the prospect of creating a new field and copying the data into that field, etc., but that is exactly what Access does, albeit behind the scenes.  So I would be very surprised (not the first time) if you find a way to dynamically alter the size without copying their contents.

My 2 cents worth.

OK. I have no alternative.
I believe it.
Nobody here could help.

But so far, acperkins has the best description of the reason.

Thanks to Arthur too. :-)
