I am looking to replace values in a particular column. For example the following column values
column name ---------- Test1 Test2 Test3 Test12
should be (replacing est1 with rest1)
est1
rest1
column name ---------- Trest1 Test2 Test3 Trest12
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')
