Hi, You should try querying them all (so that you don't have to create an invalid query) via a Java program and then check the value of the property once the object is instantiated in order to issue a delete if the prop value is wrong.
You may have to do this via chained queued tasks if your data is big. regards didier On Apr 7, 8:53 pm, Ben <bencarl...@gmail.com> wrote: > Hello, > > I have a strange problem in the app engine data viewer (admin tools). > I have entities in my app that have an email property, but the value > of email is ''... blank.
