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).
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.
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[ 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
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, xyz789
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.
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.
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.
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'.
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.
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.
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 2 table patient & PatientServiced and i want to join both the table the common field is id(patient) & patient_id(patientservices) so what will be the sql query for it?
But I need to add that we only want part# that have a reporting code that is, are not blank in this table "Audia" ItPRT# would join on the other prt# and then we want this col added to the output: IARCC9
and then we need to sort by that as well.

I want to select a few fields from table Detail, and then one field from the table Ink, but when i do this the sql server says: Ambiguous column name 'inkModel'. Can anyone help me out?
SELECT userDeptName, userDeptCategory, inkModel, quantity, dateOfTheRequest, AprovedBy FROM Detail
INNER JOIN Ink ON Detail.inkModel = Ink.inkPrice WHERE Ink.inkPrice = 1200.00
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]);
I have 2 table with one having customer info like personal details. The other table has sales records of each customer. I need join these 2 tables and retrive only the latest sales record per customer. How could I do this. Any help appriciated.
I 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
Hi all, Lets say that i have 3 tables, they are already related together, information on each of the 3 tables and their relationship between eachother can be found below:I am using Microsoft SQL Server 2005 Database in Visual Web Developer 2008 using VB programming (ADO.NET)The 3 tables are as follows:
FloorRoomLocation
Fields inside each of the tables can be found below:
The Relationships between the 3 tables are as follows:
ID field in Floor table is referenced by the field named FloorID in the Room Table ID field in Floor table is referenced by the field named FloorID in the Location table
NOTE: Location Table serves only as an extension to Floor table thus they have a 1 to 1 relationship, due to My Projects Lead's instructions I am not allowed to consolidate the Floor Table and the Location Table as 1 whole table. Floor Table has a 1 to Many Relationship with the Room Table.
I Have already done the physical relationships between each of the 3 tables in the Database Diagram, in Visual Web Developer 2008 Express Edition under the Database Explorer
So i have created this form to accept user input:
this form is in a aspx page called AddRooms.aspx
Country Name:______________ (data sent to location table)
City Name:_________________ (data sent to location table)
Building Name:______________ (data sent to location table)
FloorID:[This is a DropDownList which is databinded to the Floor Table]
Room Name:_______________ (data sent to room table)
*Just imagine that the above is a form to accept user input
*With a hit of a submit button all data will be sent to their respective tables in the database
Now i know that i have to JOIN tables in my database in order for my application to work, but i have no experience performing JOIN, i need great guys like you to help me apply JOIN to the 3 tables mentioned above, do let me know if you have any doubts in what i am trying to do.
Do give me that code that i can either apply in the (VB environment Visual Web Developer 2008) and/or in Microsoft SQL Server 2005 environment
Just need the SQL Statment that i will need to construct to perform the JOIN i need to.
Ok, I have tried this a million ways, and I am just stumped...
I have a access statement I am trying to convert to a T-SQL Statement.. There is no reason I should be having such a hard time with a simple query. Please Help!
UPDATE Tbl1 INNER JOIN Tbl2 ON Tbl1.ID = Tbl2.ID SET tbl1.Field1 = tbl2.Field1
Hi, I was wondering if it would be possible to do a join on a grouped select. SELECT Top 1 forumThreads.psRelTopId FROM forumThreads where forumThreads.psRelTopId > 0GROUP BY forumThreads.psRelTopId This will return a specific psRelTopId and I would like to retrieve the psSubject column that is associated to that row. How would I do a join in this scenario, am looking to see if it can be done in one step as opposed to a two step process. This is within a Stored Procedure of course.
