Alter a column char length

a151b096-b879-4ff8-b0a5-f0072d1ad444Sep 6 2018 — edited Sep 7 2018

Currently I am having a table with 4 columns

Eg:

My table name is : student.

Columns : I'd, name, marks, section.

When I describe the table. Let's say these data is visible.

Column name     data type              length      char length

ID                          Number (30)          30.              30

Name                  Varchar2(40) .         40 .             20

Marks                   Number (30)          30.              30

Section .              Varchar2(40) .         40 .             20

Now I am trying to modify the column Name.

My requirement is to change the char length of column Name to be increased to 60.
