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
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.

i've two tables. such as tableA and table B table A has a column named CreatedBY and table B the same column.. now i need to get only the rows which match with table A's createdby column.. suppose tableA has only 2 values. when i make the join with tableB it shows as 4 values
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?
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 have 2 tables. One with col1,col2 and second one with col1,col2,col3. My requirement is to compare col1,col2 of t1 with t2 and update only changed records in t2. How to implement? Please advise.
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.
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.
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.
hi, I knew how to join 2 tables but i have a process to select 3 tables. I have a sample table and field below. I want to join Parts & Orders using field Prt_no and Supplier & Parts using field Sup _code
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?
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)
i have 2 tables with a common ID in both tables. one table has more number of rows than the other i want to a query which gives the list of ids or rows which are missing in the other table.
left,right,inner jopins only give me common or common + right/left i want only the missing once.
hi, 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.

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.
Hi everybody I know how to join two tables with [INNER JOIN] or [LEFT/RIGHT OUTER JOIN] Keywords ,But when i have more than two tables , always i mixed up and have difficulty to build the query specially when i have to use LEFT or RIGHT OUTER JOIN Keywords!!! and that's why i always use SQL Server Query Builder and let it to make the query string for me. i couldn't understand how SQL SERVER build the [FROM] section of the query ,really what method (Algorithm) does it uses to Build the query String??? could anyone point me or give me some advices? is there any book to this topic?
I have have 3 tables TableA, TableB and TableC. TableA holds the keysto TableB and TableC. I need a query which will display the detailsfrom TableB and TableC depending on the key in TableA.For eg.TableA - columns {id, relatedkey, recordType} ===recordType will holdvalues like TableB or TableCTableB - columns{id, column1}TableC - columns{id, column1}the query should match the related key to the id of TableA or table Bbased on recordType and show the column1 value with the TabelA id sooutput for this should beid recordType column11 TableB value of TableB column12 TableC value of TableC column1Please help.CheersNick

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.
How can I join to or more tables? I tried by going to the table and right clicking, did update and changed the name to the table I wanted to update, but I keep getting errors, like for <
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
