Mysql: Selecting values between two columns

I'm trying to select a value between 2 columns. Here is my dataset

id    from    to    price
1     0.00    2.00  2.50
2     2.00    3.00  3.00
3     3.00    4.00  4.50

My goal, if I have a value of 2 is to select the line with the ID 1 (between from and to). So here is the query I'm using :

select * from table where 2 between from and to;

And here are the results that MySQL returns when executing this query :

id    from    to    price
1     0.00    2.00  2.50
2     2.00    3.00  3.00

And the result I'm looking for is the following :

id    from    to    price
1     0.00    2.00  2.50

I've tried using < and >, etc. But, I'm always getting two results. Any help would be much appreciated.

You could try this:

SELECT * FROM `table` WHERE 2 BETWEEN `from` AND `to`

You can also try this ,

select * from table where (from-to) = 2  // if you want the exact distance to be 2 
select * from table where (from-to) >= 2 // Distance more than 2

Query 1:

select * 
from `table` 
where `from` < 2 and `to` >= 2

SQL Fiddle Example

Output:

| ID | FROM | TO | PRICE |
--------------------------
|  1 |    0 |  2 |     3 |

Query 2:

select * 
from `table` 
where `from` < 2.001 and `to` >= 2.001

Output:

| ID | FROM | TO | PRICE |
--------------------------
|  2 |    2 |  3 |     3 |

Note: With this approach, you will get no rows back for value 0, unless you modify the query to accommodate that.

SO, you don't want the lower bound to be inclusive, right?

SET @value = 2;
SELECT * FROM table WHERE from > @value AND @value <= to;
