It is better to identify each summary row by including the GROUP BY clause in the query resulst. All columns other than those listed in the GROUP BY clause must have an aggregate function applied to them.

This should be what you are after. Just select the column you want to group by and then group by that column. Also as you are not aggregating is_ref you can plug it in to the where clause.

##### Comments

- Please provide sample data and desired results. Your explanation doesn't make sense.
- You have issue with Syntax in the script.
- Your query won't probably run. You are grouping by one column and selecting non-aggregated columns. That rarely works.
- actually it can work pretty well under special cases @TheImpaler MySQL supports optional ANSI/ISO SQL:1999 feature which is called Functional Dependence ..Here is it also mentioned
- Where do I begin?
`SELECT *`

doesn't work with`GROUP BY`

.`HAVING`

is to evaluate aggregate. - Put having clause back in for your use.
