Question

I have 2 tables I am working with.

Table 1 has 10 categories, entries do not change. unless I change.

Cat_NO | Cause
1      = Animal
2      = Bird
3      = Bear
4      = Dog
5      = Snake
6      = Human
7      = Cow
8      = Car
9      = Fire
10     = Rain

Table 2 has data coming randomly when event occurs. unknown number of record/data.

has following fields

ID     Cat_Code   DateTime    Location    OtherField1   OtherField2

786      7           ...        ...           ...          ...
787      6           ...        ...           ...          ...
789      7           ...        ...           ...          ...
791      1           ...        ...           ...          ...
793      3           ...        ...           ...          ...
794      1           ...        ...           ...          ...
796      4           ...        ...           ...          ...
806      9           ...        ...           ...          ...

I am trying to write query that would give me total for all category in Table 1

Result should be

CAUSE       Total        Hours(I can do this) Field2(this too) Field3(This also)
Animal        2
Bird          0     
Bear          1
Dog           1
Snake         0
Human         1
Cow           2
Car           0
Fire          1
Rain          0

So far I’ve written

SELECT
       Cause
from Table1

Answer 1

select t1.cause, count(t2.cat_code) as total
from table1 t1 left outer join table2 t2 on t1.cat_no = t2.cat_code
group by t1.cause
