Replacing NULL with 0 in a SQL server query

Question

I have developed a query, and in the results for the first three columns I get NULL. How can I replace it with 0?

  Select c.rund

If you are using Presto, AWS Athena etc, there is no ISNULL() function. Instead, use:

SELECT COALESCE(myColumn, 0 ) FROM myTable
