Sql Query Receive name instead of ID
I am making an query in which I want to see the total reserves that the client has ... The problem is that I get the client ID ... and not the client name as desired. Someone can help me?
My current query
Select Reserva.ID_Cliente, count (Reserva.ID_Reserva) From Reserva left outer join Cliente on Reserva.ID_Reserva = Cliente.ID_Cliente group by Reserva.ID_Cliente
I remember that with this query I get the client ID ... but I wanted to receive the Client Name and not the ID.
In the reservation table I only have client ID and not the name, otherwise I would select the name and not the ID.
Shouldn't you be joining by Reserva.ID_Cliente ? Anyway, just add what you need it in the Group By:
Select Cliente.Name, count(Reserva.ID_Reserva) From Reserva left outer join Cliente on Reserva.ID_Cliente = Cliente.ID_Cliente group by Reserva.ID_Cliente, Cliente.Name
Sql Query Receive name instead of ID, Shouldn't you be joining by Reserva.ID_Cliente ? Anyway, just add what you need it in the Group By: Select Cliente.Name, count(Reserva. SELECT DISTINCT borrower.customer_id, customer_name FROM borrower, customer WHERE borrower.customer_id = customer.customer_id AND borrower.customer_id NOT IN (SELECT customer_id FROM depositor) ; Find the names of customers who have a loan at the bank, and whose names are neither Raja nor Debabrata.
Note: You are using a left join, meaning a reserve might not have a corresponding Client.
Select Cliente.ClienteName, count (Reserva.ID_Reserva) From Reserva left outer join Cliente on Reserva.ID_Reserva = Cliente.ID_Cliente group by Reserva.ID_Cliente, Cliente.ClienteName;
SQL Query Help - Convert Category ID to the text name, Hey therenot a great query writer but learning all the time. We have a simple help desk app where I track all of my | 8 replies | Microsoft SQL 2) GROUPS - This table will tell the group name & grp id. Combining both tables in query will give you the users & roles in meaningful form. e.g below is the query I use for getting info from specific project. I use this with excel macro to obtain data in meaningful form
Try the following:
Select isnull(Cliente.Name, 'Name missing'), count (Reserva.ID_Reserva) From Reserva left outer join Cliente on Reserva.ID_Reserva = Cliente.ID_Cliente group by Cliente.Name, Reserva.ID_Cliente
This assumes that the table
Cliente contains the name field. The left join does not help! as mentioned elsewhere
UPDATE I've added the left join back in and also included a null check on the name. As mentioned, this assumes a reservation without a matching client.
Lesson 3: Selecting Data, From SQLCourse.com: an interactive online training course for SQL beginners.
