Question

I have two tables “client” and “proposal” in database,

db.client = > id,name
db.proposal => clientID,proposalID

select * from proposal will select all the clientID and proposalID
I want query, so that it print all proposal.proposalID with client.name instead of clientID

Answer 1

Another approach to “join” two tables:

SELECT proposal.proposalID, client.name
FROM client, proposal
WHERE proposal.clientID = client.id;

Warning: I didn’t test this.

In order to understand what’s going on, I suggest you learn more about SQL Joins.
