Question

How can I do a select that IF San_Cliente.NomeCompleto IS NOT NULL THEN San_Cliente.Excluido = 0 ?

Nowaday this is my SELECT

SELECT  Key.Key_Id, 
        Key.User_Id, 
        Key.From, 
        su.CompleteName, 
        Key.Company_Id, 
        Key.User_Id_Responsible, 
        Key.DateTime, 
        Key.Transaction, 
        Key.Client_Id, 
        Key.DateTimeGet, 
        Key.DateTimeDelivered, 
        Key.Hours, 
        Key.ResponsibleName, 
        Key.PersonalId,
        User.CompleteName AS NomeUsuarioVenda, 
        Client.CompleteName 
FROM    San_Chave 
JOIN    User 
    ON  Key.User_Id_Responsible = User.User_Id 
JOIN    User su 
    ON  Key.User_Id = su.User_Id 
LEFT OUTER JOIN Client
    ON  Key.Client_Id = Client.Client_Id 
WHERE   (Key.Delivered = 0 OR Key.Delivered is NULL) 
    and Key.From = 14
    AND User.Deleted = 0 

In my WHERE clause, I need put AND Client.Deleted = 0, but just if Client.CompleteName is not null.

How can I do that ?

At the very end, add this condition

AND (San_Cliente.NomeCliente is null OR San_Cliente.Excluido = 0)

So if San_Cliente.NomeCliente IS null, the record passes the WHERE clause.
When it IS NOT NULL, then it checks the additional filter.

To summarize,

• IF San_Cliente.NomeCompleto IS NOT NULL THEN this condition is added to the WHERE clause: AND San_Cliente.Excluido = 0
• IF San_Cliente.NomeCompleto IS NULL THEN the condition is NOT added
