Hello SQL Experts,
I have a question... I want to group and then merge one column that has different values in one. Example -->
nametelefoncity
max456berlin
max345berlin
nick 123 new york
and I want them that way -->
max 456,345 berlin
nick 123 new york
So I want them group by name and city but the telefon columns should be merged in one...
Is there a good way to solve this problem? Maybe using rownumber???
Thank you!!!:-):-)
