Question

Can I select like this?

SELECT DISTINCT idClient, idAcc,Description 
FROM client, account 
WHERE (account.idCliente = client.idCliente  
    OR account.idCliente is NULL )

Im getting trouble because it show to me duplicated results 😡 How can I do it ?

Thanks

EDIT:

RESULTS

idClient idAcc Description
    1   3   good    
    1   2   bad 
    1   3   bad

Note that im getting 2 diferent Descriptions for same idAcc

EDIT2:

I realy need that search by NULL or Not NULL.

You are using an implicit join. Try using an explicit JOIN like so:

SELECT DISTINCT Description 
FROM client
LEFT JOIN account ON account.idCliente = client.idCliente
