I'm attempting to build a module that will allow me to update one field of a
record (using a value from a previous record) based on the value of another
field in the same record. I can successfully "cycle" through the records
one at a time and get to the appropriate field as well, but any attempt to
read the field values (using SELECT, of DoCmd.RunSQL "SELECT.... ) result in
errors.
I've searched the help file and this newsgroup but haven't found an answer.
Any help greatly appreciated.
Thanx

Currentdb.execu te "Update mytable set myfield = " & mystoredvalue & "where
MyIDfield = somevalue", dbfailonerror
It may need more/less quotes depending on datatypes.

Why a module and not an update query? It's usually easier just to design
such a query in the design grid, and then if you need to have it run in a
module paste the SQL text in. Jet will cycle through records much faster
than VBA.

Thanx Peter,
This gets me part way there (at least in terms of my understanding). I
still don't know how to "remember" the value from a previous record
(mystoredvalue in your sample).
Taking baby steps, I guess...
Thanx again

Good question. I didn't know I could store a previous record's value for
use in updating a subsequent record within an update query. I'll have to
see how to make that happen.
Thanx much

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".

For most users, this new feature is actually very convenient. If you want to control the update process,...
