I have updated the column type from VARCHAR(140) to text from the database itself, is that ok?

Regards
Ruchin Sharma

Yes, via alter table you can update type to BLOB or TEXT

Ya, its done then thanks @saurabh6790

@saurabh
After changing the datatype of custom fields it again got changed back to Varchar.
Is there any other way that we can permanently get rid-off this stuff without removing the fields itself?
