There is a field 'description' which is meant to contain
words and phrases for searching.<br>
I wish to search a text field in the database but cannot get
anything other than the following to parse:<br>
<br>
searchstring=request.form['sea<wbr>rchstr'];<br>
cur = g.db.execute('select * from entries where
description like (?) order by id desc',(searchstring,))<br>
<br>
any attempts to add %'s etc seem lead to failure. I can
build the sql string myself but would like to make it safe.<br>
Any ideas how to do this?<br>
