Re: MS Access 2007 update write conflict problem & resolution

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The bigger problem is using time stamps to find the record for updating

Timestamps will not be unique as more than 1 record can have the same value

I suggest changing the updating method to use a unique key.

Hi,

We’ve been struggling with an MS Access 2007 app that updates a PG table.   It was working,  and then it wasn’t. 

It looks like we recreated the table without specifying the precision on the timestamp columns.

 

PG is defaulting to timestamp(6), which doesn’t work with MS Access.  The finest precision Access can deal with is timestamp(3).

When the record is retrieved from PG it displays 6 microseconds,  when Access prepares the update, the value is rounded to 3 microseconds.

The update can’t then locate the row  (timestamp mismatch), and displays  the ‘write conflict’ error.

 

Altering the column to timestamp(0) corrected the issue.

 

2 questions

1-       PGAdmin was reporting the precision as 0, while a select was displaying 6 microseconds.  Is this a known bug in pgadmin?

2-      Is there a way in PG that I can set the default precision on timestamp?

Thanks

 

I’ll cross post to the pgadmin list for the pgadmin question.
