Is that what you are looking for?

UPDATE my_table
SET my_column = REPLACE(my_column, 'abc', 'def')
WHERE my_column IS NOT LIKE '%abcd%'
AND my_column IS NOT LIKE '%abc_def%'

Whell phillip

It's not good because if i have on the text the same expression twice it
replaces both of them.

Try this:

UPDATE MyTable
SET MyColumn = REPLACE(REPLACE(REPLACE(MyColumn, 'abcd', 'xxxx'), 'abc',
'def'), 'xxxx', 'abcd');

If 'xxxx' might exist in the column, replace both occurrences of it in the
above statement with a string that you know will never exist in the column.

Revised solution:

UPDATE MyTable
SET MyColumn = REPLACE(
REPLACE(
REPLACE(
REPLACE(
REPLACE(MyColumn,
'abc_def', '|xxxxx|'),
'abcd', '|xx|'),
'abc', 'def'),
'|xx|', 'abcd'),
'|xxxxx|', 'abc_def');
