Question

I have two tables in a MySQL database. In the first column of data in table A (A1) I have integer values. In the first and second columns of table B (B1 and B2) I also have integer values. I would like to create a query which would give me the values where A1 is within the range B1 – B2. Is this possible to do with a MySQL query?

Here is an example of what I would like to know how to do:

Table A        Table B    
-------        -------    --------
123            12         24
451            450        455
199            202        210
0              499        567
23             5          40

The SQL query I am looking for would return the matching A1, B1, and B2 values:

451    450     455
23     12      24
23     5       40

Answer 1

select * from a, b where a1 between b1 and b2

is as simple as cross joins get. It’s the equivalent of an inner join in MySQL and Oracle at least.
