Question
SQL Query from 2 tables
Hi Experts!
Hopefully someone is abel to help me with a SQL query
I have 2 tabels
Customers
id
Customerno
Lastname
Firstname
contrycode
data in Customers table
id,Customerno,Lastname,Fir
1,123456,'Doe','John',1
2,654321,'Smith','Jane',1
3,987456,'Brown','Jack',2
4,125468,'Black','Joe',1
Table Programs
id
customerid
level
ContryCode
Data in programs table
id,customerid,level,contry
1,1,3,1
2,1,1,1
3,1,7,1
4,3,1,2
5,4,1,1
6,4,1,1
7,4,1,1
8,4,2,1
9,4,1,1
What I am trying to accomplish is to pull all names from my customers table that have a level average higher than 1.3
and in addtion I would like to pull the names of those customers that have no rows in the programs table at all.
The query below:
select distinct(customerno),Lastn
where customers.contrycode=1
and (Select convert(float,sum(level))/
or (isnull((Select convert(float,sum(level))/
Gives me the result
123456,'Doe','John',1
What I would like is the result
123456,'Doe','John',1
654321,'Smith','Jane',1
Could someone be kind enough to show me how to get customers with no rows in programs table included in the result?
