Hello,

Yes I have tried it and it gives me field definition error.

I think the problem lies in declaring right kind of data type . decimal(10,2) or numeric(10,2) doesn't work.

The syntax you gave in your original post works for me. There must be another error in your code. Have you posted all your code?

When posting a question like this, you may want to include information such as the database you are using. It could be that you we try something on SQL Server that works, and you think we're looking at Access.

Thanks for your replies

I am using this in Access.The statement

Database problem

hey all,

I think this is more problems with the computers i am working on, i don;t have administrator rights, rather than the database itself...

I have a database file that i would to have as many applications to access it as possible, but the problem is since i don't have the rights the sql server reportst that under default configurations remote connections cannot be established. However when i add it to each individual application is added it and works fine.

My question is, is there a way i can have a central database as i would do if i could have sql server running?

I am using C# as the programming language.

Thanks all,

Best regards...

the list of customers who own all stocks

12-Nov-07 14:29

You mean, you wanna host the SQL database locally, right?

If you are using SQL 2000, you can install MSDE on your Windows 2000, XP. or you can install SQL server if your OS is the server-type (e.g. Windows 2000 Advanced Server or Windows 2003)

If you are using SQL 2005, you can install SQL 2005 Express (Advanced setup that includes the Management Studio) on your Windows XP or Vista.

Let's say there are three tables (Customers, Stocks, CustomersStocks) in my database.

Customers
- CustomerID
- CustomerName

Stocks
- StockID
- Stockname

CustomersStocks
- CustomerID
- StockID

My question is ~ How can I get the list of customers who own all stocks?

For example, I have the data as below ~

Customers
- 1 | Michael
- 2 | Julia
- 3 | Lilian

Stocks
- 1 | Apple
- 2 | Orange

CustomersStocks
- 1 | 1
- 2 | 1
- 3 | 1
- 3 | 2
- 1 | 1

I wanna get the list of customers who own all stocks. In my example, the result will be "Lilian" . (should NOT include "Michael" as he doesn't own all stocks and he just own one stock twice.)

I wrote this SQL query below ~

<br />
SELECT DISTINCT dbo.Customers.CustomerName<br />
FROM         dbo.CustomersStocks INNER JOIN<br />
                      dbo.Customers ON dbo.CustomersStocks.CustomerId = dbo.Customers.CustomerID<br />
WHERE STOCKid <br />
GROUP BY dbo.Customers.CustomerName, dbo.CustomersStocks.StockID, dbo.CustomersStocks.CustomerId<br />
HAVING      (dbo.CustomersStocks.StockID =<br />
                          (SELECT     COUNT(*) AS CountOfStock<br />
                            FROM          dbo.Stocks))

It works okay.. but the customer who own a stock twice (e.g. "Michael" in my case) included in the result.. This is the problem..

So, How can I get the list of customers who own all stocks?

Thanks in advance.

You probably need to create a view of CustomersStocks that contains only a single entry for each customer instead of the multiple entries. Perhaps a select distinct might do it.

create or replace view uniquecustomersstocks as
select distinct customerid, stockid from customersstocks

Actually, I don't want to create a view to get this result.. I think that it is possible to get the result with one line (maybe..big line) of SQL

pmarfleet12-Nov-07 10:19

12-Nov-07 10:19

One way of doing this would be:

1) CROSS JOIN Customers with Stocks to get every possible combination of customers and stocks.

2) Do a LEFT JOIN between 1) and CustomersStocks. Get a DISTINCT list of the Customer IDs where there is no matching record on the RHS of the join. These are the customers who have not bought at least 1 of the available stocks.

3) Return the records from Customers where the Customer ID is NOT IN the set of records returned in 2) These will be the customers who have purchased all available stocks.

Hope this helps.

This line will be the same as all data from CustomersStocks.

problem with stored procedure

No it won't. CustomersStocks contains combinations of customers and stocks where the customer has bought the stock. Cross joining Customers and Stocks returns the cartesian product of the two tables, ie. every possible combination of customers and stocks regardless of whether a customer has actually bought the stock. The purpose of this is to compare the difference between this set and CustomersStocks to find which customers have not bought at least one of the available stocks. Once you have identified these customers, by process of elimination you can find the customers who have bought all available stocks.

I don't think there is any way to do this. Besides, is it necessary? Stored procedure are usually coded to select data from a particular table or tables. You would know which table(s) each stored procedure used, so you could use an OUTPUT parameter to return a varchar value which was hard-coded to that table name for each stored procedure.

well using sp_depends storedprocedurename , it will list all the details of a stored procedure.

This returns the query plus a table with 1 row - 1 column that contains the table name. Seems like a waste of time since the developer already knows the table name.

CREATE PROCEURE proc1
AS
    SELECT
        *
    FROM
        student
    
    SELECT 
        'student'
