Hi there,
I'm trying to prepend a string to a field. While, this works:
db(db.person.id0).update(name = db.person.name + x)
This does not:

Thanks very much for the reply.
Sorry to say that it doesn't work. Your answer gives this...
UPDATE person SET name='xSUBSTR(person.name,1,(1 - 0))';

A bigger problem...
On further testing, it looks like db(db.person.id0).update(name =

This is ugly but should work:
from gluon.sql import Expression
db(db.person.id0).update(name = Expression('person.name || x'))
I'm almost positive there is a better way.

for row in db(db.person.id 0).select():
row.update_record(name = row.name + x)
This also will work, although not as efficient since the processing
will be done in python and not the database.

Thanks both of you for your replies. I've been trying to avoid doing
it in python (lots of records) so I think I'll try mr.freeze's
solution.
