Question

So I have a table containing fields description and short_description. I imported these values from a different system.

Now I’d need to know how to wrap these description texts into a <p> tag.

The records are always always single-paragraph, so no need for the logic for multiple <p>‘s for each two linebreaks.

What I want to do is go through each record, and add "<p>" to the beginning, and "</p>" to the end of both of these columns. However, after some googling I didn’t find out a way to include the original value in the new value for SET in UPDATE.

How would that work? Or is there a better way?

You need to concatenate the strings together:

update my_table
   set my_column = concat('<p>', my_column, '</p>')

concat returns null if any argument is null, so if my_column has no value you won’t end up with <p></p>
