It is necessary to insert / replace into the column a part of the value from another column. For example, there is a single column value "Duplicata B02341543". In the other column, you only need to insert "B02341543". For each line, the word "Duplicata" is preserved, but the value "B02341543" changes.

    update table set field2=substring(field1,10,len(field1)) 
       UPDATE <YourTable> SET <updatedField> = SomeOperation(<someField>) 
         UPDATE table_name SET filed2 = SUBSTR(filed1,11);

        11 is the length of the word "Duplicata" and a space.
