Update some values in a column based on a condition SQL Server

Question

I have a varchar column that stores dates, but the formatting is very messy. I have dates in formats mm/dd/yyyy , m/d/yyyy and yyyy-ww-0 . I want to have everything in format mm/dd/yyyy , but I'm not sure how to change the values that are m/d/yyyy and make them 0m/0d/yyyy (and update the column in the original dataset), and what to do with the dates yyyy-ww-0 .

Answer 1

try this

select format(cast([column name] as date),'mm/dd/yyyy') from [table name]
