Mysql: Find rows where column value ends with a specific substring

Question

I have a column url where all the values are urls. I\'m trying to update the value of a different column where-ever the aforementioned url ends with .pdf

Answer 1

You can use a LIKE condition with a leading wildcard. %.pdf means the column must end in .pdf

UPDATE mytable
SET newcolumn = 'PDF found'
WHERE yourcolumn LIKE '%.pdf'

Alternatively you could use the right() function

UPDATE mytable
SET newcolumn = 'PDF found'
WHERE right(yourcolumn,4) = '.pdf'
