clear blob field image

[Dfox]

Good afternoon, when trying to clear an image from a blob field it doesn't work

example

Zquery.FieldByName('logo').Value := null;

in version 7.2.14-stable it worked

Have you tried query.FieldByName('').Clear; ?

[Dfox]

Have you tried query.FieldByName('').Clear; ?

I tried and it didn't work

[Dfox]

I removed the field and added it again and it worked

thanks

You mean this field was calculated / in a memtable?
It's possible that we have a bug, would be nice to reproduce the issue so we can solve it.
