Join 3 Tables
Jul 21, 2006
Thank you, Thank you for reading my question!!! :)
I have 3 tables that need to be joined.
(Not necessarily needed info but might help: using Coldfusion with ODBC to Foxpro database)
Table 1: Timecard
--------
loginname date wrknum time
----------- --------- --------- ------
afrank 7/17/06 1 3
afrank 7/17/06 2 2
afrank 7/17/06 3 3
afrank 5/20/06 1 3
rjohn 7/17/06 1 3
.....
Table 2: Defaults
-----------
loginname wrknum
----------- ---------
afrank 1
afrank 2
afrank 3
afrank 4
afrank 5
....
Table 3: Workorders
wrknum description
---------- ---------------
1 descrip1
2 descrip2
.....
The result needs to be for the user afrank, date=7/20
and would look like:
Resultant Table:
loginname wrknum time description
----------- ---------- ------ ------------
afrank 1 3 descrip1
afrank 2 2 descrip2
afrank 3 3 descrip3
afrank 4 NULL descrip4
afrank 5 NULL descrip5
I've tried an outer left join but cannot get the right data. Basically everything from the timecard table and the leftovers from the default table with descriptions for all.

Hi guys,
I'll appreciate any help with the following problem:
I need to retrieve data from 3 tables. 2 master tables and 1 transaction table.
1. Master table TBLOC contain 2 records :
rcd 1. S01
rcd 2. S02
2. Master table TBCODE contain 5 records:
rcd 1. C1
rcd 2. C2
rcd 3. C3
rcd 4. C4
rcd 5. C5
3. Transaction table TBITEM contain 4 records which link to 2 master table:
rcd 1. S01, C1, CAR
rcd 2. S01, C4, TOY
rcd 3. S01, C5, KEY
rcd 4. S02, C2, CAR
I use Left Join & Right Join to retrieve result below (using non-ASNI method) but it doesn't work.
Right Join method:
SELECT C.LOC, B.CODE, A.ITEM FROM TBITEM A RIGHT JOIN TBCODE B ON A.CODE = B.CODE
RIGHT JOIN TBLOC C ON A.LOC = C.LOC
GROUP BY C.LOC, B.CODE, A.ITEM ORDER BY C.LOC, B.CODE
When I use Non-ASNI method it work:
SELECT C.LOC, B.CODE, A.ITEM FROM TBITEM A, TBCODE B, TBLOC C
WHERE A.CODE =* B.CODE AND A.LOC =* C.LOC
GROUP BY C.LOC, B.CODE, A.ITEM ORDER BY C.LOC, B.CODE
Result:
LOC CODE ITEM
-----------------------------
S01 C1 NULL
S01 C2 NULL
S01 C3 CAR
S01 C4 TOY
S01 C5 KEY
S02 C1 NULL
S02 C2 CAR
S02 C3 NULL
S02 C4 NULL
S02 C5 NULL
Please Help.
Thanks.

I need to perform a join on six different tables to produce a report. The biggest join I have ever done has been four tables. The way I did that query was to join three tables and then to perform the final select on the three table join.
Can anyone give me some advice. Should I use the same approach? Or can I just continue to use the keyword INNER JOIN to perform the joins?

Does a SQL server create a runtime table and write that table to disk is there is not sufficent space in RAM?

I have three tables:
1) Orders - order_id, orderdate
2) ordersdetails - order_id, partnumber, qty
3) products - partnumber
I need an output in following format
Date Partnumber qty
Following query gives the desired results.
select left(orders.orderdate,11) as date, orderdetails.partnumber, SUM(orderdetails.qty) as total
from orderdetails, orders
where orderdetails.partnumber is not null
and orderdetails.order_id = orders.order_id
and orders.orderdate >= {ts'2001-05-01 00:00:00'} and orders.orderdate <= {ts'2001-05-31 23:59:59'}
group by orders.orderdate, orderdetails.partnumber
order by orders.orderdate, total
But I do not have part that have null orders. My goal is to get
1) Get all part numbers, qty in the month of May.
2) at the end attach all partnumbers that have null ordered values to see which one have no orders.

I've got two tables, one called clientsharedeals and the clientorderdeals. In the first table, I have four fields (Rundate, Accno, Dealid, Nominal) that I need to sum(Nominal), grouping by dealid.
Once I've done this, I need to join to clientorderdeals, also having the same fields plus one extra (Rundate, Accno, Dealid, Nominal and Dealseq). Because of Dealseq, I can have more than one row in the table, matching (Rundate, Accno, Dealid, Nominal) of the first table. However, Dealseq increments, so I need to select max(Dealseq).
My query is doubling up on nominal because in my select statement, I am only using one account number, so I know what the value is for nominal and there are two rows in clientorderdeals - and it is not selecting max(dealseq) but both.
Can someone please cast some pearls my way ?
Thanks

Could somebody please explain to me how do we join a table onto itself as that is what I was advised to do but I can't quite get where I want to go.
What I want to do is list values from a table,but those values can be just a quote (what would cost if they decided to go for that option) or those values can represent what was spent and invoiced, what is confusing me is that all of that gets saved in the same table and in same columns, so what was quoted for example for AirFares and what was spent gets saved in the same record but when it is "quoted amount" then ID = 1 but when it is invoiced ID = -1 and that is how we know what was quoted and what was invoiced.
But I need to split that one field into two columns one showing AirFareQuoted and one AirFareInvoiced and i have no idea how to achieve this.
I hope this makes sense and somebody can help me

Hey Folks,
I am stuck at one place in data migration........ I have the following source tables having no PK / INDEX / Constraint defined on any of them........
T1
(
ID1 INT,
STYLE VARCHAR(34)
)
T2
(
COL_ID VARCHAR(34),
OBJ_ID VARCHAR(34)
)
T3
(
OUT_ID VARCHAR(34),
ITEM VARCHAR(34),
)
And here is the relation..........
Quote:
T1.STYLE = T2.COL_ID
T2.OBJ_ID = T3.OUT_ID
T3.ITEM = T2.COL_ID
Here is what I have tried with.........
Quote:
SELECT * FROM T3 WHERE ITEM IN
(
SELECT COL_ID
FROM T1
INNER JOIN T2
ON
T1.STYLE = T2.COL_ID
INNER JOIN T3
ON
T2.OBJ_ID = T3.OUT_ID
)
But this query is not helping me out. I mean the number of output records are 0.
Now can any one suggest me a join that includes all the 3 tables, or finetune my query?
Thanks,
Rahul Jha

hi everybody
I have a question and need answer as soon as possible. so i hope i get help. How can i join two tables have no common fields? I tried outer join but i get redundant data(repeated values).
Give me a script to solve the following problem . There are no real wrong answers, but the more efficient and bulletproof the query is the better. Assign rooms to classes based on capacity using the Classes and Rooms tables. Rules: each class should have a room (and NULL if a room is not available). No class can be in a room where there are more students than capacity. No room can be used twice.
And this is the tables query:
CREATE TABLE Classes (
ClassID int NOT NULL,
Class varchar (50),
Students int NOT NULL, CONSTRAINT PK_Classes PRIMARY KEY CLUSTERED (ClassID
) )
GO
CREATE TABLE Rooms (
Room int NOT NULL,
Capacity int NOT NULL,
CONSTRAINT PK_Rooms PRIMARY KEY CLUSTERED (Room)
)
GO
INSERT INTO Classes (ClassID, Class, Students) VALUES (1, 'Whats New for SQL Server 2008', 65)
INSERT INTO Classes (ClassID, Class, Students) VALUES (2, 'Introduction to Silverlight 1.1', 52)
INSERT INTO Classes (ClassID, Class, Students) VALUES (3, 'XQuery Deep Dive', 35)
INSERT INTO Classes (ClassID, Class, Students) VALUES (4, 'Ranking and Windowning', 35)
INSERT INTO Classes (ClassID, Class, Students) VALUES (5, 'Expression Blend 1.1', 65)
INSERT INTO Classes (ClassID, Class, Students) VALUES (6, 'Database Design Patterns', 75)
INSERT INTO Classes (ClassID, Class, Students) VALUES (7, 'CrossTabs for Dummies', 1)
INSERT INTO Rooms (Room, Capacity) VALUES (221, 30)
INSERT INTO Rooms (Room, Capacity) VALUES (222, 40)
INSERT INTO Rooms (Room, Capacity) VALUES (223, 50)
INSERT INTO Rooms (Room, Capacity) VALUES (224, 60)
INSERT INTO Rooms (Room, Capacity) VALUES (225, 70)
INSERT INTO Rooms (Room, Capacity) VALUES (226, 74)

i am facing an issue. i have got two tables say table1 and table2.
table1 has column1,2,3 ( has values a,b,c) where as table 2 has different columns 4,5,6(j,k,l).
column4 in table 2 has value which contains %+column1+% and it has two entires for each row in table1.the column4 value in table2 is different for all rows.When i am trying to join the two tables, i am getting values like
1 2 3 4 5 6
a b c j k l
a b c j1 k l
a1 b c j k l
a1 b c j1 k l
but i want to display
a b c k l
a1 b c k l
is there a way to do it.
My queries were
select distinct pc_assign_worklist.pxRefObjectInsName AS [pxRefObjectInsName],
pc_assign_worklist.pxUrgencyAssign AS [pxUrgencyAssign],
pc_assign_worklist.pyLabel AS [pyLabel],
pc_assign_worklist.pyAssignmentStatus AS [pyAssignmentStatus],
pc_assign_worklist.pxAssignedOperatorID AS [pxAssignedOperatorID],
CONVERT(char (11),pc_assign_worklist.pxCreateDateTime) AS [pxCreateDateTime],
pc_assign_worklist.pxCreateOpName AS [pxCreateOpName],
pc_index_workparty.MemberIdentifier AS [MemberIdentifier],
pc_index_workparty.LastName AS [Last Name],
pc_index_workparty.FirstName AS [First Name],
pc_index_workparty.pxInsName AS [pxInsName],
pc_index_workparty.pzInsKey AS [pzInsKey],
pc_index_workparty.pxpartySubscript as "Workparty"
from dbo.pc_assign_worklist
LEFT OUTER JOIN dbo.pc_index_workparty
ON pc_index_workparty.pzInsKey LIKE '%' + pc_assign_worklist.pxRefObjectInsName + '%'
where
pxAssignedOperatorID = 'dasxkx1'
i also tried left inner join but it always returns the same result seta.
I even created a view by inner join of two tables and then did left outer join on the second table . The result is same.
Can somebody tell whether this is achivable or not.

I am fairly new to sql and i am trying to join three tables:
SELECT *
from tbl_RegistrationInfo r JOIN tbl_Ideas i
on r.intRegID = i.intRegID JOIN tbl_Categories c
on i.intCategoryID=c.intCategoryID
where i.intIdeaID=4
ORDER BY i.DateCreated Desc
THe common key for the tables tbl_RegistrationInfo and tbl_Ideas is intRegID.
THe common key for the tables tbl_Ideas and tbl_Categories is intCategoryID.
And finally the user provides a value for the "idea" (i.intIdeaID=4).
i get a syntax error:
'syntax error in FROM clause'
I just dont see it. Can someone please help me? The small web app that I am writing will use this type of triple join often.
I did model this query from one I found online using the pubs sample db:
SELECT a.au_lname, a.au_fname, t.title
FROM authors a INNER JOIN titleauthor ta
ON a.au_id = ta.au_id JOIN titles t
ON ta.title_id = t.title_id
WHERE t.type = 'trad_cook'
ORDER BY t.title ASC

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:
Floor
Room
Location
Fields inside each of the tables can be found below:
Floor Table
(PK) ID
(Required) Name
DisplayOrder
Room Table
(PK) ID
(Required) Name
(PK, FK) FloorID
ExchangeID
Extension
IP
DeviceName
Remarks
(Required) Equipment
(Required) Floor2ID
FloorLocationX
FloorLocationY
Location Table
(PK,FK) FloorID
(Required) CountryName
(Required) CityName
(Required) BuildingName
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.
Please Help
Many Thanks : )
