How can I ensure that the names of customers 1 and 2 appear on every product?
customer1 table
cid name1
1 john
2 joe
customer2 table
cid name2
p1 sandy
p2 linda
product table
pid cid pname
1 1 phone
2 2 pencil
3 p1 pen
4 p2 paper
I want my output to be like this:
pid cid pname name1 name2
1 1 phone john NULL
2 2 pencil joe NULL
3 p1 pen NULL sandy
4 p2 paper NULL linda
Can someone help me with this?
