PostgreSQL search and replace where condition

问题

I am trying to save some manual time by search and replacing in my PostgreSQL database.

I have a table called Products_Colors where i'd like to replace all text in column color_image where column color_id is equal to 21.

UPDATE 
   Product_Colors
SET 
   color_image = REPLACE(color_image,"cars/car_2018.webp","cars/car_2019.webp")
WHERE 
   color_id = 21

Would this be correct syntax?

回答1:

I think you need a query like this :

UPDATE Product_Colors
SET color_image = 'cars/car_2019.webp'
WHERE color_id = 21 and color_image = 'cars/car_2019.webp'
