I have this query:
select DB.lname as "Friend Last Name"
from DB
In my browser it is displayed as: "Friend_Last_Name".
Why has it replaced spaces with underscores? In sql 2012 it appears as "Friend Last Name" as it is meant to.
try
select DB.lname [Friend Last Name]
from DB
select DB.lname as [Friend Last Name]
from DB

How to retrieve all the data pertaining to company name and agent from mysql? How to write the query statement?
Have you tried this?
SELECT *
FROM agent_info
WHERE policyCompany = 'Avia' and policyAgent = 'Ron';
I have to guess because you didn't tell us much about your tables, but this might work.
SELECT policyCompany,
GROUP_CONCAT(DISTINCT policyAgent ORDER BY policyAgent) agents
FROM mytable
GROUP BY policyCompany
You can read about GROUP_CONCAT() here.
