Question

For example: table name = table

column1 | column2

1              7
2              8
3              9
4             NULL
5              11
6              12

A user is asked to enter two values, one from column1 and one from column 2. Lets say user enters 2 and 12. the result should look something like this.

column1 | column2

3              9
4             NULL
5              11

I have tried by using this code below but i’m not sure if it works correctly. Plus Null values are not shown so that’s a problem too. Also, actual values contain both numeric and string values.

SELECT DISTINCT column1, column2 
FROM table 
WHERE column1 
BETWEEN '&column1' AND column1 
AND column2 NOT BETWEEN '&column2 AND column2 
ORDER BY column1;

Thank you for replying

SELECT DISTINCT column1, column2 
FROM table 
WHERE column1 
BETWEEN '&column1' AND (SELECT column1 FROM table WHERE column2 = '&column2') 
ORDER BY column1;
