Hi, all
I hope somebody can help me.
Situation
Three tables 1. +----+------------+--------+ | id | name | region | +----+------------+--------+ | 13 | Name1 | 1 | | 15 | Name2 | 2 | | 47 | Name3 | 1 | | 57 | Name4 | 2 | | 65 | Name5 | 2 | | 77 | Name6 | 1 | | 85 | Name7 | 1 | +----+------------+--------+
2. +----+------------+--------+----------+ | id | Date | amount1| current | +----+------------+--------+----------+ | 13 | 21.7.1967 | 9900 | N | | 13 | 21.7.1968 | 9800 | J | | 57 | 11.9.1999 | 12800 | J | | 65 | 24.6.1991 | 1200 | N | | 65 | 21.7.1967 | 1275 | J | | 85 | 14.2.2001 | 45000 | J | +----+------------+--------+----------+
3. +----+-------+--------+ | id | Year | amount2| +----+-------+--------+ | 13 | 1967 | 100 | | 13 | 1968 | 100 | | 13 | 1969 | 125 | | 15 | 1967 | 200 | | 15 | 1968 | 220 | | 15 | 1969 | 220 | | 47 | 1967 | 500 | | 47 | 1968 | 580 | | 47 | 1969 | 550 | +----+-------+--------+
In table 1 there are all IDs. In tables 2 and 3 there can be some IDs. As you see, in region 1 there are the IDs 13,47,77 and 85. In table 2 only 13 and 85, in table 3 only 13 and 47.
What I would like to have is a result like this: +--------+---------------------------+--------------+ | region | sum(amount1) if current=J | sum(amount2) | +--------+---------------------------+--------------+ | 1 | 54800 | 1630 | | 2 | 14075 | 640 | +--------+---------------------------+--------------+
Many thanks in advance Joachim
