Query to find sum of grouped counts from 2 tables

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



I have 2 tables containing the data for same items:

STORE1
-----------------------------
Id	type		items
-----------------------------
1	FOOD		10
2	FOOD		15
3	SOAP		20

STORE2
-----------------------------
Id	type		items
-----------------------------
1	FOOD		15
3	SOAP		10
4	PAPER		25
5	SOAP		12


What I am looking for is one single query that would return me TYPE-wise
total number of items from both the tables. UNION does not help me. I
want the result as:

Type		count
-----------------------
FOOD		40		//10+15+15
SOAP		42		//20+10+12
PAPER		25

Thanks in advance,
-Satish
