MySQL选择数组值在最小值和最大值之间的行

Question

I have this issue that i'm stuck in...

I have a field like an array, values separated by space. Let's say we have these values:

v1: "100 150 200 300"
v2: "50 100"
V3: "130 230 415"
v4: "340 500 600"
...

Then i have two user input values like a min and a max, let's say 120 and 300. I need to select with mysql from table all rows that have an array value between these min and max

So the output should be v1 and v3 from the previous example.

Can someone help me, please?

Answer 1

I completely agree with the comments saying that this is terrible design, but I think this could be solved with a function that splits your array into its respective values, combined with an APPLY.

This should then yield a table like

v1 100

v1 150

etc.

v2 50

v2 100

etc.

From there the problem should be easy.

Answer 2

I would check this thread Split value from one field to two

Or pull the data back and use server-side code to split the value into an array and then do the comparison.
