Use REPLACE:

SELECT REPLACE(t.column, 'est1', 'rest1')
  FROM MY_TABLE t

If you want to update the values in the table, use:

UPDATE MY_TABLE t
   SET column = REPLACE(t.column, 'est1', 'rest1')

In Oracle, there is the concept of schema name, so try using this

update schemname.tablename t
set t.columnname = replace(t.columnname, t.oldvalue, t.newvalue);

I'm using Version 4.0.2.15 with Build 15.21

For me I needed this:

UPDATE table_name SET column_name = REPLACE(column_name,"search str","replace str");

Putting t.column_name in the first argument of replace did not work.

If you need to update the value in a particular table:

UPDATE TABLE-NAME SET COLUMN-NAME = REPLACE(TABLE-NAME.COLUMN-NAME, 'STRING-TO-REPLACE', 'REPLACEMENT-STRING');

where 

  TABLE-NAME         - The name of the table being updated
  COLUMN-NAME        - The name of the column being updated
  STRING-TO-REPLACE  - The value to replace
  REPLACEMENT-STRING - The replacement
