Now I need to copy the value from Name to Url and replace the space to -

So, The table must be like after copy :-

11   News title test2       News-title-test2           22-10-2014
12   News title test3       News-title-test2           22-10-2014
13   News title test4       News-title-test2           22-10-2014

Are there way to do that by SQL or PHP

Answer 1

Simply update the table and use the REPLACE() function

UPDATE table
SET Url = REPLACE(Name,' ', '-')
