Value should be 0 between the two dates?

Question

Using SQL Server 2000

I want to compare the table2.date between table1.from, table1.todate, if exist then value should be 0 (zero)

Table1

ID From         


        

Answer 1

This will show value for the records present, 0 for the records missing:

SELECT  t2.id, t2.date,
        COALESCE(
        (
        SELECT  TOP 1 t2.value
        FROM    table1 t1
        WHERE   t2.date BETWEEN t1.fromdate AND t1.todate
                AND t2.id = t1.id
        ), 0) AS value
FROM    table2 t2

This will work other way around: 0 for the records present, value for the records missing:

SELECT  t2.id, t2.date,
        COALESCE(
        (
        SELECT  TOP 1 0
        FROM    table1 t1
        WHERE   t2.date BETWEEN t1.fromdate AND t1.todate
                AND t2.id = t1.id
        ), t2.value) AS value
FROM    table2 t2

Answer 2

select t2.id, t2.date, coalesce(T.value, 0) value
from table2 t2
left join 
     (select t22.id, t22.date, t22.value
        from table2 t22
       where not exists (select null from table1 t1
                          where t22.date between t1.fromdate and t1.todate)
     ) T on t2.id = T.id and t2.date = T.date
