Question

Select * FROM table WHERE a<=9 AND a>=4 AND b<=20 AND b>=16 AND c<=30 AND c>=26

Now I want to end up selecting from query 1 the results in which at least two of the following criteria are met.

Select * FROM table WHERE a<=7 AND a>=5 AND B<=19 AND B>=17 AND C<=29 AND c>=27

Numbers could be anything, although on query 2 these are lower for the less than eqaul and higher for the bigger than equal.

I want to be able to set the number of minimum coincidences to be met at query 2 with a number.
For example 5 coincidences must be met at query 2 to end up making a selection in query 1.

This is about range and matches count, if there is an easier way to achieve this great.

Answer 1

i think this kind of query will do your job

Select 
*,
(IF(a<=7 AND a>=5,1,0) + IF(B<=19 AND B>=17,1,0) + IF(C<=29 AND c>=27,1,0))
as totalmatch
FROM table
HAVING totalmatch >=2
