How to replace specific values in a oracle database column?

Solution 1
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')
Solution 2
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

Tom Shaw about 8 yearsIn Oracle this should be UPDATE t, not UPDATE TABLE t.

nbrooks about 7 years@Tom Presumably 'TABLE' is used here as the fictional table name (and 't' is the alias). The select statement is also getting values from a similarly named fictional table.
