Question

With this query

SELECT least(col1, col2, col3) AS fancyTitle
FROM table
ORDER BY fancyTitle

how can fancyTitle be compared to a value so that I only output the values that are higher than 100, for example.

Answer 1

You have to put + operators between the columns you want to SUM(). You can’t pass in a comma-separated list to SUM()

You can do:

SELECT id, SUM(col1 + col2+ col3) AS fancyTitle
FROM tbl
GROUP BY id
HAVING SUM(col1 + col2 + col3) > 100
