How to display multiple queries in different columns?

Hey,

is it possible to get the three results in three columns with different headlines?

%sql select avg (safetyscore) as AVGSAFETY from chicagopublicschools where schooltype = ‘ES’ union select avg (safetyscore) as AVGSAFETY from chicagopublicschools where schooltype = 'HS’ union select avg (safetyscore) as AVGSAFETY from chicagopublicschools where school_type = 'MS’

n this case the result appears like this:

avg_saefty
48
49.52…
49.62…

thanks

Tobi

Hi @Tobi0909,

As far as I know, it is possible, what you are looking at is a crosstab query.

MySQL’s crosstabs contain aggregate functions on two or more fields, presented in a tabular format. In a multi-aggregate crosstab query, two different functions can be applied to the same field or the same function can be applied to multiple fields on the same (row or column) axis.

You can check the following link where it’s more thourohly explained Cross tab query in MySQL

Hope this helps!
