I need to write a query to output a table with 2 values – number & description.
Table 1 has 2 columns – id and date
id date
101 04-07-2018
102 15-11-2018
103 25-01-2019
104 28-06-2019
Table 2 has 3 columns – start date, end date and value
start date end date value
29-11-2016 28-11-2017 A
29-11-2017 29-11-2018 B
30-11-2018 15-03-2019 C
16-03-2019 29-06-2019 D
30-06-2019 31-11-2021 E
For id 101, 04-07-2018 falls between 29-11-2017 and 29-11-2018, value should be B. For 102, 15-11-2018 falls between 29-11-2017 and 29-11-2018, it starts with B, but later 11/2018 is updated in the next row 30-11-2018 and 15-03-2019, final value should be C instead of B.
I am trying to achieve the final table. Any suggestions would be appreciated.
id desc
101 B
102 C
103 C
104 E
