mysql - removing CHAR(13) CHAR(13)

Question

I'm new to sql and i'm trying to remove carriage returns and line feeds from a column I imported from a csv file.
I'm using the code:

SELECT replace(replace(column,CHAR(13),''),CHAR(10),'')
FROM table

It correctly finds all the CR and LF, but it doesn't update the database. please advise.. thank you in advance! much appreciated.

Answer 1

Your query retrieve from your table named TABLE all rows with the column replaced.

About UPDATE your database you must use UPDATE command in this way:

UPDATE table SET column = replace(replace(column,CHAR(13),''),CHAR(10),'')

If you want condition the UPDATE about the satisfaction of some conditions, so you must add the WHERE clause.

For example

UPDATE table SET column = replace(replace(column,CHAR(13),''),CHAR(10),'')
WHERE column_2 = 'XXX'
