Relationships lost and record deleted

[trandel]

I have a peculiar problem.

The sequence of events is:

1. The user reports that on clearing (deleting) data in a memo field within a table an error (sometimes) occurs which results in all fields for that record containing the word #deleted. The table can no longer be opened for update via a form. (Prior to deleting the data in the memo field the user had been using copy/paste data from the memo field into other fields within the record)

2. When I open the table in datasheet view, there is a record filled with # signs usually at the beginning of the table. I delete that ( I believe that is all that is left of the original record - but there is no other identifying data).

3. The primary key (autonumber) of that table is reset i.e. it is no longer designated as the primary key. I recreate it in table design.

4. All relationships with that Primary key are deleted.

5. I recreate the relationships, run a compact and repair and all is well except that the original record is lost and has to be recreated as well.

All this because a user deleted some data in a memo field!

The DB is split with the BE on a Windows 2003 Server and the users running their FEs on a Lan. Only Access 2003 is used.

I cant replicate the problem on my development system.

Any ideas very welcome

Memo fields are prone to corruption and of course so is Access generally. I would import the backend data into a new database and replace the current backend, also try to avoid the use of memo fields entirely.

Also, are you placing the relationships in the backend or the fronts? Better in the front I suspect.

Ok -I will try out importing to a new db for the BE - but wont it simply copy the 'problem' whatever it is?

I will try and get rid of memo fields - I used them way back when I didnt realise they were a problem!! Conversion to text might be interesting............

I think relationships have to be in the BE where the tables are - the FE inherit them. I tried to build one recently in a FE and it would not allow me to enforce relationship integrity. Imagine the possibilties if one was llaoed to have differing relationships amongst the FEs?

Importing into a new db is a tried and true method of repairing corruption. It will work pretty well in many cases. You are correct re the relationships, my mistake.
