I am trying to create a view that encapsulates some specific info from many different tables. I have about 30 tables all with exactly the same field names and field types. I want to take 3 of the fields from every table and put them together into one 'VIEW' so I can run more efficient queries. SQL however, doesn't let you 'combine' 2 columns from different tables into one column in the view. (making sense?)
I tried running a 'UNION' but you are specifically NOT allowed to run a union in a create view statement. Anyone have any ideas?
PhoneType is an auxiliary table that has 5 records in it Home phone, Cell phone, Work phone, Pager, and Fax. Is there a way to do a join or maybe make a view of a view that would allow me to ultimately end up with…
StudnetID: 1 Name: John HomePhone: 123-456-7890 WorkPhone: 123-456-7890 CellPhone: Pager: 123-456-7890 Fax: Memo: This is one student record.
Some students will have no phone number, some will have all 5 most will have one or two. If possible I would like to do a setup like this in my database to keep from having to have null fields for 4 phone numbers that the majority of records won’t have. Thanks in advanced, Nathan Rover
I have created a join statement with 3 tables in my database. The join wokers fine but the result is not on the format (Layout) I need it. Here is where I need help. Let me explain what I need to accomplish. I have 3 tables in my database 1- Rates (Master Table) Every Prepaid long distance card have a list of countries with individual rates 2- Countries_Template (Child table used to get the country name) This table is to get copy of a list of countries every time a new card's rate is created 3- Card_Denominations (Child table where I create all the price denominations of each card) Each cards have multiple cards denominations ($2, $5, $10, $20 and so on) so every time a card is inserted in the Cards table I insert the card denominations on the Card_Denominations table. The format I need to return from my Query using above 3 tables have to look like this: Flag Country Rate $2 $5 $10 $20 pic USA .20 500 750 1200 1700

I have 3 tables that I'm trying to joing together in an SQL statement. I've tried several different JOIN statements, but can't seem to get it to work correctly.
Scenario:
I want all records from TABLE_1 I want to LEFT JOIN TABLE_1 to TABLE_2, but I only want records from TABLE_2 that are an 'Active' STATUS. My problem is, the STATUS field is in TABLE_3.
I have to link TABLE_1 to TABLE_2 by ITEMNUM. I have to link TABLE_2 to TABLE_3 by ORDERNUM since TABLE_3 does not have ITEMNUM, and pull across the STATUS.
TABLE_1 is an ITEMID table. TABLE_2 is our ORDER_LINE table, and TABLE_3 is our ORDER_HEADER info. I want all items listed; then I'd like to see all items that are on an order (TABLE_2), but only if the ORDER_HEADER (TABLE_3) is an 'ACTIVE' STATUS.
I am attempting to run the following select statement joining multiple tables but in the end result I would like only Distinct/Unique values to be returned in the invlod.lodnum column.
[select pw.schbat, adrmst.adrnam, adrmst.adrln1, adrmst.adrcty, adrmst.adrstc, adrmst.adrpsz, invlod.lodnum, shipment.host_ext_id, shipment_line.ordnum, car_move.car_move_id from aremst join locmst on (aremst.arecod = locmst.arecod) and (aremst.wh_id = locmst.wh_id)
I am currently having this problem with gridview and detailview. When I drag either onto the page and set my select statement to pick from one table and then update that data through the gridview (lets say), the update works perfectly. My problem is that the table I am pulling data from is mainly foreign keys. So in order to hide the number values of the foreign keys, I select the string value columns from the tables that contain the primary keys. I then use INNER JOIN in my SELECT so that I only get the data that pertains to the user I am looking to list and edit. I run the "test query" and everything I need shows up as I want it. I then go back to the gridview and change the fields which are foreign keys to templates. When I edit the templates I bind the field that contains the string value of the given foreign key to the template. This works great, because now the user will see string representation instead of the ID numbers that coinside with the string value. So I run my webpage and everything show up as I want it to, all the data is correct and I get no errors. I then click edit (as I have checked the "enable editing" box) and the gridview changes to edit mode. I make my changes and then select "update." When the page refreshes, and the gridview returns, the data is not updated and the original data is shown. I am sorry for so much typing, but I want to be as clear as possible with what I am doing. The only thing I can see being the issue is that when I setup my SELECT and FROM to contain fields from multiple tables, the UPDATE then does not work. When I remove all of my JOIN's and go back to foreign keys and one table the update works again. Below is what I have for my SQL statements:------------------------------------------------------------------------------------------------------------------------------------- SELECT:SELECT People.FirstName, People.LastName, People.FullName, People.PropertyID, People.InviteTypeID, People.RSVP, People.Wheelchair, Property.[House/Day Hab], InviteType.InviteTypeName FROM (InviteType INNER JOIN (Property INNER JOIN People ON Property.PropertyID = People.PropertyID) ON InviteType.InviteTypeID = People.InviteTypeID) WHERE (People.PersonID = ?)UPDATE:UPDATE [People] SET [FirstName] = ?, [LastName] = ?, [FullName] = ?, [PropertyID] = ?, [InviteTypeID] = ?, [RSVP] = ?, [Wheelchair] = ? WHERE [PersonID] = ? ---------------------------------------------------------------------------------------------------------------------------------------The only fields I want to update are in [People]. My WHERE is based on a control that I use to select a person from a drop down list. If I run the test query for the update while setting up my data source the query will update the record in the database. It is when I try to make the update from the gridview that the data is not changed. If anything is not clear please let me know and I will clarify as much as I can. This is my first project using ASP and working with databases so I am completely learning as I go. I took some database courses in college but I have never interacted with them with a web based front end. Any help will be greatly appreciated.Thank you in advance for any time, help, and/or advice you can give.Brian

I am having the following situation - there is a view that aggregates and computes some values and a table that I need the details from so I join them filtering on the primary key of the table. The execution plan shows that the view is executed without any filtering so it returns 140 000 rows which are later filtered by the join operation a hash table match. This hash table match takes 47% of the query cost. I tried selecting the same view but directly giving a where clause without the join €“ it gave a completely different execution plan. Using the second method is in at least 4 folds faster and is going only through Index Seeks and nested loops. So I tried modifying the query with third version. It gave almost the same execution plan as the version 1 with the join operation. It seams that by giving the where clause directly the execution plan chosen by the query optimizer is completely different €“ it filters the view and the results from it and returns it at the same time, in contrast to the first version where the view is executed and return and later filtered. Is it possible to change the query some how so that it filters the view before been joined to the table.
Any suggestions will be appreciated greatly Stoil Pankov
"vHCItemLimitUsed" - this is the view "tHCContractInsured" - this is the table "ixHCContractInsuredID" - is the primary key of the table
Here is a simple representation of the effect:
Version 1: select * from dbo.vHCItemLimitUsed inner join tHCContractInsured on vHCItemLimitUsed.ixHCContractInsuredID = tHCContractInsured.ixHCContractInsuredID where tHCContractInsured.ixHCContractInsuredID in (9012,9013,9014,9015)
Version 2: select * from vHCItemLimitUsed where ixHCContractInsuredID in (9012,9013,9014,9015)
Version 3: select * from dbo.vHCItemLimitUsed where ixHCContractInsuredID in (select ixHCContractInsuredID from tHCContractInsured where ixHCContractInsuredID in (9012,9013,9014,9015))
I have three table and I have to fetch some data from each one. This can be done by calling three diffrent stored procedures for each one.But it can be done with view and joining these three tables and only one time calling this view and getting the same result.(These joins can be from diffrent database too)
Which one is better View and joining these three tables and call this view one time or calling three stored procedures in for example .net side.
I have a simple query that joins a largeish fact table (3 million rows) to a view that returns 120 rows. The SKEY in the view is returned via a scalar function. The view returns instantly if queried on it's own however when joined to the fact table in the simple query below results in a query execution plan that runs forever. Interestingly if I change the INNER JOIN to a LEFT OUTER JOIN the query returns the matched results almost instantly.
Select Dimension.Age_Band.[10_Year_Age_Band], Count(*) From Fact.APC_Episodes Inner Join Dimension.Age_Band ON Fact.APC_Episodes.AGE_BAND_SKEY = Age_Band.AGE_BAND_SKEY Group By Dimension.Age_Band.[10_Year_Age_Band]
I know joining to a view using a column generated by a scalar function is not a good recipe for performance. I also know that I could fix this by populating a physical table with the view first as I have already tested this though I hoping not to have to go down that route.
Why a LEFT OUTER JOIN works and not an INNER JOIN or anyway I can get the query optimizer to generate an execution plan that works?
I have created 3 views, which I then want to join to produce an overall result. The first view returns customer details, along with payment information. The next two views return values only when the customer has purchased extras outside our standard product i.e. if there is no purchase of an extra, then nothing is written to the extra's table. When I join the views together they only return values where data has been matched in all 3 views i.e. extra's have been purchased. Any data that did not match in all 3 view (i.e. no extra's purchased) is either ignored or dropped from the results. So I need my script to return all values even if no data exists in the two extra views.

Write a CREATE VIEW statement that defines a view named Invoice Basic that returns three columns: VendorName, InvoiceNumber, and InvoiceTotal. Then, write a SELECT statement that returns all of the columns in the view, sorted by VendorName, where the first letter of the vendor name is N, O, or P.
This is what I have so far,
CREATE VIEW InvoiceBasic AS SELECT VendorName, InvoiceNumber, InvoiceTotal From Vendors JOIN Invoices ON Vendors.VendorID = Invoices.VendorID
Hi. I'm new to SQL, and need to join 2 tables... any hints??? table1:id (int)title(varchar(50))body(text) table2:id (int)title(varchar(50))body(text) somehow need to get the id, which table the record is from, and the title and body... so if the tables had the information: table1:id title body1 "first title" "first body"2 "second title" "second body"3 "third title" "third body" table2:id title body1 "first title" "first body"2 "second title" "second body"3 "third title" "third body" I would like to get... id table title body3 1 "third title" "third body"3 2 "third title" "third body"2 1 "second title" "second body"2 2 "second title" "second body"1 1 "first title" "first body"1 2 "first title" "first body" Does anyone know how to get this? I am fairly flexible if i need to change things... cheers, eh!
Hello everyone,I'm starting a new project right now and am trying to cut down on the number of stored procedures and tables I'm gonna have to use and I have run into a dead end.Up till now I have been doing the following: Say I had a PRODUCTS table with a DesignId column and ColorId column. I would then create a DESIGN table (Name, Id) and a COLOR table (Name, Id) to INNER JOIN with the two columns in my PRODUCTS table. And the same goes for all my other tables: ORDERS, CUSTOMERS, LINKS etc...... And in the end I would have a lot of tables and stored procedures for these category columns. So I thought, it would be nice to just have a Categories and Subcategories table for all my category columns for the whole website. That way every time I need to define a category column for any table I can simply just add the values to my Categories and Subcategories table instead of having to create a new table for every category column. Everything is fine and dandy except for trying to INNER JOIN these two tables with more than one column. To get values for one column is no problem:<code> SELECT *, _SubCategories.SubCategoryNameFROM _ProductsINNER JOIN _SubCategoriesON _Products.DesignId = _SubCategories.SubCategoryIdWHERE DesignId = COALESCE (@DesignId, DesignId)</code> But how do you INNER JOIN the ColorId column as well. Both DesignId and ColorId values are in my _SubCategories table. In a stored procedure: Is there any way to create a table and columns. Run a loop statement, with one INNER JOIN . Rerun another loop statement with a new INNER JOIN statement? Would that work or does any one else have an idea what would?Thank you guys for the help. It is much appreciated. Alec
Hello all, I have two datatables "customersReached " and "customersGuessed " and I want to combine them into one table only, the problem is that one table exeeded to the other by two fields, so what can I do??????? Mahmoudona
I've been trying to think about how I can do this. I have forums that I have written built around SQL Server. Basicly you have:
-A users Table -A Posts Table -A Replies Table.
Posts and replies have very similar structures. I'd like to be able to merge them and pick out the earliest post for said forum.
1 - is there a way to merge them so that the post date for both the replies and posts tables is contained in 1 column. If not is there a better alternative.
I'd also like to add indexing to the posts so I can do paging. Is there a way for me to add an index number to them while I can sort them anyway i want.
I am using MS SQL Server 2005 on Windows XP with SQL Server Management Studio Express CTP. I am having issues with my query on joining 2 tables I created using BETWEEN to restrict the Salary. Table 1 is called Employee and Table 2 is called Job_title. The column Job_title_code is the only column that is in both tables which is how I am joining both tables. Here is my SQL query:
Code:
SELECT Employee.*, Job_title.*
From Employee
INNER JOIN Job_title
ON Employee.Job_title_code=Job_title.Job_title_code
WHERE Salary
BETWEEN 50000 AND 500000;
The results I am getting back are:
Msg 207, Level 16, State 1, Line 7 Invalid column name 'Job_title_code'.
I can't figure out how to fix this error. I feel like I have tried everything, so any help will be much appreciated. Thank you.
Hi, I have a table with fields as partnerid, contractno. The partnerid field has the Id number which can be a supplier or a customer. I need to get the partner id(supplier) and the partner id (customers) of that particular supplier only. I tried with self join but the data is data is replicating.

When I try to join table4 with table i am getting a exception
Ps: as the original code was in SQL SERVER 6.5 I have to use *= for joins not keywords LEFT JOIN or RIGHT JOIN
I have a bit of an issue that I can not seem to figure out and was hoping to get some feedback/advice from you all.
First a little background. I have two databases and I am adding a new table too one of them. However I need to join the two databases but by columns and the columns I want to use to join them will use different data types and values.
Example database 1 column 1 will be groups.group.id and database 2 column 1 will be users.group.id. However in database 2 (users) the group_id will contain different data.
Database 1 group.id will contain a single integer and database 2 group.id I want to have it contain multiple integers seperated by a comma.
Example code: select groups.group.id, groups.group.name from groups, users where groups.disabled='1' and users.user_id = $user_id and groups.group.id ? users.group.id
The "?" is where I am having trouble. Does anyone know of a way to join two databases by columns using different data types?
Hi, i have some sql experience and can link tables but the link i am trying to get is not displaying how i need it to
here is the code i am using, which display logical results, but not the ones i need :P
qry = "SELECT * FROM wce_contact INNER JOIN wce_mailer_link ON wce_contact.UNIQUEID = wce_mailer_link.Contactid LEFT JOIN wce_mailer ON wce_mailer.uniqueid = wce_mailer_link.mailerid RIGHT JOIN wce_mailer_attachments ON wce_mailer_attachments.uniqueid = wce_mailer.fileid WHERE wce_contact.uniqueid = '"& Request.QueryString("id") &"'"
Ok i have these tables
wce_contact This has the contacts name and address
wce_mailer This holds the details of the mailer and a link to the wce_mailer_attachments, there would be multiple rows in wce_mailer_attachments table which link to 1 row in wce_mailer.
wce_mailer_link This holds the wce_contact uniqueid, and the wce_mailer uniqueid. there will be many contacts to many mailers
wce_mailer_attachments This holds an individual row for one attachment, but the uniqueid would be the same for multiple rows, Dependant on how many attachments the users adds. i.e. one mailer could have several attachments, they would all have the same uniqueid.
Basically the results i am getting using the join i built are displaying each attachment as a separate row when i display the mailers assigned to a contacts record. i need them to display in one single row where the uniqueids are the same in the wce_mailer_attachments and they match the only fileid in wce_mailer.
Hi all! I have a problem joining three tables. My tables are: rooms: room_id ¦ room_name computers: computer_id ¦ computer_name ¦ room_id bookings: booking_id ¦ computer_id ¦ date
I want to join them so that i get a listing that displays all room names, and if there is a booking for any computer in that room I also want to display the computer name and the booking date next to the room name. If one room has bookings for several computers I would like to display that room several times.
I have gotten a correct result with:
SELECT rooms.room_name, t.computer_name, temp.date FROM rooms LEFT JOIN (SELECT computers.room_id, computers.computer_name, bookings.date FROM computers JOIN bookings ON (bookings.computer_id = computers.computer_id)) AS temp ON (rooms.room_id = temp.room_id)
but I would like to use something shorter like: SELECT rooms.room_name, computers.computer_name, bookings.date from computers INNER JOIN bookings ON (computers.computer_id = bookings.computer_id) RIGHT JOIN rooms ON (computers.room_ID = rooms.room_ID)
That however gives me a list where every combination of rooms and computers is listed and bookings displayed when there is a match. I don't really get why this doesn't work and I've been staring at it for days. Could somebody help me out? (I'm using PHP and MySQL)
Let say i have 3 tables (tblA, tblB, tblC). I want to get all data in tblA. At the same time, i want to join the tables. If value in column aStatus equal to 1, it will get the value from tblB. If the column value is 2, it will refer to tblC. Else, if it 0, no need to refer to any table. just like inner join.. but i dun get the logic of how im going to do that.. can someone advise me on how to do the joining? please refer to picture below.
