Connecting 3 memo-fields in query produces weird (chinese?) characters instead of field values

hi,
I just updated yesterday from Access 2000 to Access XP. Everything seemed to work fine, I´ve been working all day in the system, but now I´ve found one strange problem (don´t know if its to do with the update or just coincidence):

I have a table "Products" with the fields "name", "types" and "extrasearchvalues". All 3 fields are Memo fields.
Now in a query I have a field:

Searchfield: ([Products].[Name] & " " & [Types] & " " & [Extrasearchvalues])

the result is that "types" and "extrasearchvalues" are displayed correctly, but instead of "Products.Name" some weird (chinese?) symbols appear.
In the same query, however, I show the "Products.Name" field on its own, and it shows the right values. So there must be something wrong with the joining, but what? I need some help!

Can you copy and paste an example of the joined memo field where the unusual characters appear?

hi,
here are a few examples.


쨀 Samsung SGH-V200 Lithium Ionen

묃 Nokia 5210 6510 7650 8210 8250 8310 8850/8890 8910/8910i Lithium Ionen

脀 Nokia 3100 3310/3330 3410 3510/3510i 6310/6310i 6510 6610 6650 7210 7250/7250i 8310 9210/9210i

贇 Nokia 5210 8210 8250


I´ve just found another weird thing. I made a backup of the database this morning, since then I´ve not really changed anything, just deleted lots of records from one table. But in the backup from this morning the query works. So it can´t have anything to do with the Office XP update...

(in my query chinese letters appear, the system here seems to have converted them to "쨀" etc...)

What are the correct 'names'?

쨀 Samsung SGH-V200 Lithium Ionen
I assume that the errant info goes from the ampersand '&' to the block that preceeds Samsung.

What should this value be?

the value should be

"Li-Ion Akku ca.1000mAh "

I´ve just tried something else - I copied back the table from which I deleted about 10000 records today, and it works. So obviously something in this table (which is connected with the "Products" table) has gone wrong. Any idea what could have happened??

Have you tried doing a compress/repair on the Db ? That often takes care of such.

yes I've tried "compact and repair", it doesn't help. I've now copied the original table back - it worked - then deleted 10 records - it still worked - then re-deleted the 10000 records and the problem is there again. Something happens when I mass-delete in this table...

Did you comp/repair BEFORE the deletion?

Anyhow, it still sounds to me like a question of database corruption, - especially considering that you are making extended use of memo-fields (in my experience, they are actually not the strongest feature of Access).


- this is just an attempt at a work-around:

you could try to extract anything but the records you want to delete to a temp table, and then see if that table gives you same result.

hi,
thanks for you help, but I've found the problem (although I don't know what causes it)... its a relationshop problem. When I deleted the relationship between the "products" table, and the table with the records I deleted, the problem disappeared. So I've now modified the query using a different sort of relationship and it works.

No idea what happened, anyway thanks to all for your help!

I'm having this same problem.  My user has sent the database back with Chinese characters.  Apparently it also created a new record "0".  

I have not had a chance to look at it, but starting Monday, that is my prime concern.  

Anyone have a "fix"?
