Question

What would be the SQL syntax to select 4 different columns in a single row in a table, add those together and then insert that value into a 5th different column in the same row? The columns are all numeric(11,2).

For example- Table name is DataCheck
there is an ID that is primary key so how do I select col1, col2, col3, col4 where ID = 232…etc and add them up, and insert into col4 where id = 232…etc

Answer 1

Unless I’m misunderstanding:

UPDATE MyTable SET col5 = col1 + col2 + col3 + col4 WHERE id = 232
