Hi,
I have a database column of char(250); I can insert enmass a string
into said column using:
update tablename set columnname = concat(columnname, 'string');
but how do I undo that?
Is there a function that is exactly the reverse of concat such
that:
update tablename set columnname = unconcat(columnname, 'string');
will actually delete 'string' pattern from columnname?
thanks
Jaime
