Insert line break in postgresql when updating text field

Question

I am trying to update a text field in a table of my postgresql database.

UPDATE public.table SET long_text = \'First Line\' + CHAR(10) + \'Second line.\' WHE         


        

Answer 1

PostgreSQL:

varchar + varchar = ERROR. \ r and \ n is not anywhere that works, for greater compatibility use:

Corret:

UPDATE public.table SET 
   long_text = concat('First Line',CHR(13),CHR(10),'Second line.')
WHERE id = 19;
