如何从 sql 中的表行记录中获取唯一记录数

Question

Simple SQL question, I searched but can't seem to find the answer already asked.

I have SQL table with unique numbers in the same row and I would like to get a count of unique records in the same row. I will use it as a PHP variable later.

Please, somebody, help me to get the count of unique records.

Expected result is
Total count of 1 = 6
Total count of 4 = 2
Total count of 5 = 2
Etc..

I'm sure this is a duplicate but I can't lay my hands on it so.. Unpivot using union then group by

with cte as
(select id,'q1' as question,question1 from <table>
union all
select id,'q2' as question,question2 from <table>
union all
select id,'q3' as question,question3 from <table>
....
)
select id,question,count(*)
from cte 
group by id,question;
