For discussion sake, I've got two tables: customers and orders. What I want
is a query that will return the most recent order for each customer. Let's
say the tables are like:
Customer: customerId, customerName
Orders: orderId, customerId, orderDate
The simple joins I've done give me back all of the orders for all of the
customers.
Any advice?
I have one control table to store all related table name
Table ID TableName
1 TableA
2 TableB
In Table A:
RecordID Value
1 1
2 2
3 3
In Table B:
RecordID Value
1 1
2 2
3 3
How can I get the result by select the Table list first and then combine the data in table A and table B?
Thank you!
I have table 'stores' that has 3 columns (storeid, article, doc), I have a second table 'allstores' that has 3 columns(storeid(always 'ALL'), article, doc). The stores table's storeid column will have a stores id, then will have multiple articles, and docs. The 'allstores' table will have 'all' in the store for every article and doc combination. This table is like the master lookup table for all possible article and doc combinations. The 'stores' table will have the actual article and doc per storeid.
What I am wanting to pull is all article, doc combinations that exist in the 'allstores' table, but do not exist in the 'stores' table, per storeid. So if the article/doc combination exists in the 'allstores' table and in the 'stores' table for storeid of 50 does not use that combination, but store 51 does, I want the output of storeid 50, and what combination does not exist for that storeid. I will try this example:
'allstores' 'Stores'
storeid doc article storeid doc article
ALL 0010 001 101 0010 001
ALL 0010 002 101 0010 002
ALL 0011 001 102 0011 002
ALL 0011 002
So I want the query to pull the one from 'allstores' that does not exist in 'stores' which in this case would the 3rd record "ALL 0011 001".
I am using stored procedure to load gridview but problem is that i am not getting all rows from first table[Â Subject] on applying conditions on second table[ Faculty_Subject table] ,as you can see below if i apply condition :-
Faculty_Subject.Class_Id=@Class_Id
Then i don't get all subjects from subject table, how this can be achieved.
Sql Code:-
GO
ALTER Proc [dbo].[SP_Get_Subjects_Faculty_Details]
@Class_Id int
AS BEGIN

If I join Table1 to Table2 with a WHERE condition, isit the same if I would join Table2 to Table1 consideringthat the size of the tables are different.Let's assume Table2 is much bigger than Table1.I've never used MERGE, HASH JOINs etc, do any ofthese help in this scenario?Thank you

Hello I have a Source database and a Target database.
I want to join one table from the source to the other table in the target.
Please can some one write a sql query for this.
i gues its something like
select tablesource.col,tabledest.col
from database..tablesource,database..tabledestination
Ok One more question is where do I execute this Query in which database.. IF at all its possible to this.
Is it possible to insert data into a table from a temporary table that is inner join?
Can anyone share an example of a stored procedure that can do this?
Thanks,

Hi there. I haven't been able to figure out how to join a table on column on multiple table names. Here's the situation:
I have a table "tblJob" with a key of jobID. Now for every jobID, the program creates a new table that keeps track of the stock before the jobId was processed and after it was processed to give accurate stock levels and show the difference in stock levels. So, a jobID of 355 would be related to the table: "tblPreStock_335" and "tblPostStock_335". These 2 tables have all the materials in stock and the quantity. Therefore they show how much material was used. I need to figure out the difference in the material in the stock before and after the processing.
That means that I have to get a stockID, get the associated pre and post tables, and then display the difference of ALL the materials in the pre and post tables.
Could someone help me get started on the right path? Even a link to similiar problem that I haven't found would be nice.
Thx
I have one main Table "MainTable" which I want to relate with "subTable1, subTable2, ..." in such a way that:
"ith subTable" have to be related/joind on "ith row" of the "MainTable", "jth subTable" have to be related/joined on "jth row" of the "MainTable" and so on...
What I want Actually?
I want that when ever I delete a Record in the "MainTable", The corresponding "subTable" have to be deleted Itself.
I thought a solution that, I can cerate a Trigger on Delete of the "MainTable" and it would delete the corresponding "subTable". But I dont know how to ceate that.
Secound solution what I thought is, that may be there is some majic power in the Table Joinings. That I might join "MainTable" row with "subTable" ( ofcourse that I dont know either :))
So my question is, that what is the actual solution for my problem?
What ever solution is please give me a sample also with that. Like in a Trigger how can I write some Expression which can delete the "subTable" for the Currunt delete Row.

I was writing a query using both left outer join and inner join. And the query was ....
SELECT
       S.companyname AS supplier, S.country,P.productid, P.productname, P.unitprice,C.categoryname
FROM
       Production.Suppliers AS S LEFT OUTER JOIN
      (Production.Products AS P
        INNER JOIN Production.Categories AS C
[code]....
However ,the result that i got was correct.But when i did the same query using the left outer join in both the cases
i.e..
SELECT
       S.companyname AS supplier, S.country,P.productid, P.productname, P.unitprice,C.categoryname
FROM
       Production.Suppliers AS S LEFT OUTER JOIN
(Production.Products AS P
LEFT OUTER JOIN Production.Categories AS C
ON C.categoryid = P.categoryid)
ON
S.supplierid = P.supplierid
WHERE
S.country = N'Japan';
The result i got was same,i.e
supplier   country   productid   productname   unitprice   categorynameSupplier QOVFD   Japan   9   Product AOZBW   97.00   Meat/PoultrySupplier QOVFD   Japan  10   Product YHXGE   31.00   SeafoodSupplier QOVFD   Japan  74   Product BKAZJ   10.00   ProduceSupplier QWUSF   Japan   13   Product POXFU   6.00   SeafoodSupplier QWUSF   Japan   14   Product PWCJB   23.25   ProduceSupplier QWUSF   Japan   15   Product KSZOI   15.50   CondimentsSupplier XYZ   Japan   NULL   NULL   NULL   NULLSupplier XYZ   Japan   NULL   NULL   NULL   NULL
and this time also i got the same result.My question is that is there any specific reason to use inner join when join the third table and not the left outer join.
I'm having trouble with a multi-table JOIN statement with more than one JOIN statement.
For each order, I need to return the following: CarsID, CarModelName, MakeID, OrderDate, ProductName, Total ordered the Car Category.
The carid (primary key) and carmodelname belong to the Cars table.
The makeid and orderdate belong to the OrderDetails table.
The productname and carcategory belong to the Product table.
The number of rows returned should be the same as the number of rows in OrderDetails.
Here's my issue. I've got a series of tables like so:
dbo.CustomerBobJones
dbo.CustomerJaneDoe
dbo.CustomerBrianSmith
Each contains these columns:
DateOfComment datetime
CommentText varchar(200)
Now all other customer information is stored in another table dbo.CustomerList
CustomerID int
CustomerName varchar(50)
Address varchar(50)
and so on.
I need to join from this customer list to the individual tables for those customers.
My thought was to add to dbo.CustomerList the name of the table associated to that account... but I'm not sure once that information is entered how I'll be able to join between them.
I had thought that the id in sysobjects might be the key but I'm not sure how to join using an id instead of a table name.
Can anyone throw me a bone on this?
I have two tables:
Orders, with OrderID as primary key, a code for the client, and a code for the place of delivery/receipant.
Both the client and place of delivery should be linked to the table:
Relations, where each relation has it's own PrimaryID which is a auto-numbered ID. Now I want to substract my orders, with both the clientcode, and the place of delivery code linked to the relations table, so that for both the name and adress is shown.
I can link one of them by:
InnerJoin On Orders.ClientID = Relations.ClientID, but it's not possible to also link to the ReceipantsID. Is there a way to solve this?

I am attempting to join 2 table variables on 2 keys, employeeID and employerID
SELECT * FROM @employees
INNER JOIN @addresses
ON ((@employees.employeeID = @addresses.employeeID) AND (@employees.employerID = @addresses.employerID))
Both tables are declared with proper fields and they are populated with the correct data; I get this error msg upon execution.
Server: Msg 137, Level 15, State 2, Line 28
Must declare the variable '@employees'.
Any ideas on what's going wrong?
All,
I have two tables, A and B.
Table A has names, address, phone.
Table B has names and image filename.
Table A and B can be linked by names.
I would like to show all the names in Table A and link to Table B such that it will show a column image filename if there is a image filename. If the name cannot be found in the Table B display a NULL on the column.
(Note : there may be two same names in the Table B, so how can i show only the first image filename).
Kindly advise.
thanks.
Hi All,
Im trying to write a SQL statement that will join 2 tables based on a customer has 2 specific products.
eg.
Table 1: Customer
MemberID
MemberName
Email ect
Table 2: Products
ProductID
MID (MemberID of table 1)
ProductName
So how do i write a sql statement to only bring up say cutomers that have a ProductName of "Computers" AND "Laptops" They must have both Computers as an entry in the products table and an entry of Laptops in the relational database.
Your help would be much appreciated.

I am trying to join 5 tables in a sql server 2k db. Does anyone know of a good set of guidelines for doing this? Alternately, could someone find the problem in the following query?
The query that I am using is listed here (please let me know if I am violating any programming guidelines on this):
SELECT p.ParticipantID, pr.Age, ir.FnlTime, e.EventDate
FROM Participant p INNER JOIN PartRace pr ON p.ParticipantID = pr.ParticipantID
JOIN IndResults ir ON pr.ParticipantID = ir.ParticipantID
JOIN RaceData rd ON ir.RaceID = rd.RaceID
JOIN Events e ON e.EventID = rd.EventID
WHERE rd.Dist = '5_km' AND p.Gender = 'm' AND ir.FnlTime <> '00:00' AND e.EventGrp = 1
ORDER BY ir.ParticipantID
The problem that I am having is that if a participant shows up multiple times (which they could do since this is designed to get the performances for an event over a series of years) it does not associate the correct data from year to year. Basically some times show up where they shouldn't.
For example... say i have this query:
Code:
select
table1.indicator
table2.name
table2.lastname
left join table2
on table1.client_name = table2.lastname
where table1.indicator = '1952423'
But I also have found out that "requestors" are also stored inside table2...
I cant do another join table2 on table1.requestor_name = table2.lastname
I am not sure what the correct way of doing it is, I think I can use IN() but I am not so sure...
I have a company table at below.
HTML Code:
comid companyname parentcompany maincom
------- ----------- --------------
1 test 0 1
2 testxx 1 0
So here the second record i have parent company = 1 meaning company test as parent for textxx , if a company has parentcompany as 0 means tat has no parent company.
So in this i need have a result to display in grid is
HTML Code:
companyname parentcompany
test no
testxx test
I tired with inner join , but it is only select the second record as it's skip the first record due inner join with comid .

I have 5 tables that I need to link with 1 table (All tables have a PolicyCode).
The problem is that I have to link it so that the result tells me what PolicyCodes in the 1 table was matched to either of the other 5 tables.
I would like to start using SQL Server CE rather than SQLite for an application I am developing, due to it's replication support for SQL Server however there appears to be a gaping hole in it that means I can't even consider it. Specifically to do with aggregates against detail tables.
Is there any way to do the equivalent of the following in SQL using SQL Server CE?
SELECT [Customer_Id], [Customer_name], COALESCE([OT].[Count_Orders],0) [CountOrders], COALESCE([OT].[Sum_Value],0) [OrderValue] FROM [Customers] LEFT OUTER JOIN (SELECT .[Customer_Id], COUNT(*) [Count_Orders], SUM(.[Order_Value]) [Sum_Value] FROM [Orders] GROUP BY .[Customer_Id]) [OT] ON [OT].[Customer_Id] = [Customers].[Customer_Id]);
Any help would be most welcome

How to write a left join using just one table? I have to select things using left join. Can you give just a example?
View 1 Replies View RelatedI remember when studying for exam 70-528 that I read a practice question that said it was better to return 2 select satements rather than a join on two tables as this would be more efficent. The question from MCPD Self Paced Training Kit: Designing and Developing Web Based Applications Using Microsoft .NET Framework (Certification Series): Designing and Developing ... Applications Using Microsoft .NET Framework was:
You are an ASP.NET application developer. You are participating in the design of a Web retail application.
The application accepts orders from the clients and stores them in a SQL Server 2005 database. Each order contains header information (order date, client information, and shipping address) and details information, which includes information about ordered products. Each detail line contains information about one ordered product and its quantity and price.
All of the preceding information will be stored in two database tables: one table called Orders for the order header and another table, called OrderDetails, for order details in which each record in the orders table could have one or more related records in the OrderDetails table.
When the user selects the specific order ID, the application is supposed to select all the information about the order from the database, and you need to create a stored procedure that allows selection of information about all the fields for the stored order from the database, based on a provided order ID value.
Which of the following stored procedures do you recommend creating in a database to achieve the best performance on a database server side and reduce network traffic between application and database server?The answer was:CREATE PROCEDURE ORDERS_SELECT_ORDER @ORDER_ID INT AS
SELECT * FROM Orders WHERE OrderID=@ORDER_IDSELECT * FROM OrderDetails WHERE OrderID=@ORDER_ID
RETURNAs oppose to the traditional:
CREATE PROCEDURE SP_SELECT_ORDER @ORDER_ID INT AS
SELECT * FROM Orders LEFT JOIN OrderDetails ON Orders.OrderID = OrderDetails.OrderlD WHERE Orders.OrderID=@ORDER_IDThe explanation was:
To achieve the best performance, avoid names of the stored procedures that start with sp_ prefix. If the name of the stored procedure starts with sp_ SQL Server always looks for the stored procedure in the master database first because all the system stored procedures start with the same prefix and are stored in a master database. It requires extra effort from the server to locate the stored procedure. This occurs even if you qualify the stored procedure with the database name. To avoid this issue, use a custom naming convention rather than the sp_ prefix.
In addition, using a join inside of the stored procedure for the provided scenario will require an extra task from the server to join the data and produce a joined result. It will also lead to the redundant data for the header information that will be duplicated with each detail of the order and will increase traffic between the client and the server. Using only two separate SELECT SQL statements will allow you to avoid a join operation and reduce the size of the returned data to the client.Any one got any views on this as I have never actually seen this demostrated in a sample applcation. Is it a lot more efficent?ThanksScott
