Question

I have 2 tables like this:

Table 1
-------
ID
score

Table 2
-------
ID
score_from
score_to

How do I get ID from Table 2, if I have score=’12’ in Table1 based on score_from and score_to in Table 2 ?

Contents of Table1:
----------------------
ID          |Score   |
----------------------
1           |12      |
----------------------
2           |40      |
----------------------

Contents of Table2:
------------------------------
ID       |score_from|score_to|
------------------------------
1        |0         |20      |
------------------------------
2        |21        |40      |
------------------------------

If I have score=’12’ from table1, how can I write a query to get ID=’1′ in table2?

Answer 1

Try this one,

SELECT a.`ID`, a.`Score`, b.`ID`, b.`score_from`, b.`score_to`
FROM   table1 a, table2 b
WHERE  (a.score BETWEEN b.score_from AND b.score_to) AND
        (a.score = 12)

or if you want only the ID

SELECT b.`ID`
FROM   table1 a, table2 b
WHERE  (a.score BETWEEN b.score_from AND b.score_to) AND
        (a.score = 12)
