I have a table with a column I would like to update its values.

I have a table with a column I would like to update its values. Here is an example of TSQL codes:

WITH Pieces(id, newdesc) AS ( SELECT itemid, REPLACE(REPLACE(description, 'DESC_A', 'DESC_B'), 'NEW_1', 'NEW_2')   FROM myTable   WHERE description like '%DESC_A%DESC_B%' ) -- SELECT * FROM Pieces UPDATE myTable SET description = newdesc // not working, how?

This update is NOT working. By commenting out SELECT, I can see the result is what I need. How I can do this change in a batch way for a group of rows? Not sure is it possible by WITH statement?

Here are some example data:

.... xxxDESC_AyyyDESC_Bwwww aaaDESC_AxxDESC_Beee ....

the udpated ones will be:

.... xxxNEW_1yyyNEW_2wwww aaaNEW_1xxNEW_2eee ....
