Join Two Tables Together Using Particular Field
Sep 19, 2014
I am trying to join two tables together using a particular field. The code to reproduce is:
declare @chris as table
(
chrisid int identity (1,1) primary key,
name varchar(100),
SrvStopID int
)
[Code]...
My result is:
chrisidname SrvStopIDchrisidname SrvStopID
1Neal 1 1John 1
1Neal 1 2Jacob 1
1Neal 1 3Jinglehiemer 1
1Neal 1 4Smith 1
2SmithSon 1 1John 1
2SmithSon 1 2Jacob 1
2SmithSon 1 3Jinglehiemer 1
2SmithSon 1 4Smith 1
and my result should be: Just the results in @Neal that match SrvStopID in @Chris

I have a table activity which show the activities of the site. An activity could be related with no other entity or it could be related with an account, or with a contact or with an opportunity. An opportunity and a contact could be also related with an account.
My problem is that I need to show the activity and the related account (if there is any) but because the relationship with an account could be done by different ways, I dont know how to do it without join the account table several times.
This is my current query:
SELECT AC.IdActividad, CU.idcuenta
FROM Actividades AC LEFT JOIN Tareas TA ON TA.IdActividad = C.IdActividad
LEFT JOIN ActividadesXCuenta AXC ON AC.IdActividad = AXC.IdActividad LEFT JOIN dbo.Cuentas CU ON axc.IdCuenta = CU.IdCuenta
LEFT JOIN dbo.ActividadesXOportunidad axo ON AC.IdActividad = axo.IdActividad LEFT JOIN dbo.Oportunidades o ON axo.IdOportunidad = o.IdOportunidad LEFT JOIN dbo.Cuentas CU1 ON o.IdCuenta = CU.IdCuenta
LEFT JOIN dbo.ActividadesXContacto axco ON AC.IdActividad = axco.IdActividad LEFT JOIN dbo.Contactos con ON axco.IdContacto = con.IdContacto LEFT JOIN dbo.Cuentas CU2 ON o.IdCuenta = CU.IdCuenta
As you see, I have the table Cuenta joined 3 times. That means that I need to put the ActivityID field 3 times but based on how the report was developed, I could not do that.

I have a table of "applicants" with unique applicant id and another table "reviews" with reviews which has unique id and Emplid and contains general program name like Math and then may contain 3 addition rows for specific program like Calculus, algebra, geometry etc.
There may or may not be a record for each applicant id in table reviews or there can be 1 or more than one record in reviews based on level of review( General or Specific).
All the general reviews has “Math” as Program_code but if there are more reviews, they can have Program_code like “Cal” , “Abr”, “Geo”
I want to join the tables so I can get all the records from both the tables where Program_code in reviews table is “Math” only.
That is I want to join the table and get all the records from reviews table where the program_code is “Math” only
How can I do that?

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

Hello Experts,
Been struggling with this issue all morning and beginning to get a headache. Essentialy my problem is this. I have a gridview control that ive bound to datasource where the select statement is using an inner join to retrieve textual info from one table in refernce to an object_id contained within both. i.e
SelectCommand="SELECT 'multiple fields from both tables'FROM ZCRMTAB_ACTIVITY INNER JOIN ZCRMTAB_ACT_LOG ON ZCRMTAB_ACT_LOG.OBJECT_ID = ZCRMTAB_ACTIVITY.OBJECT_ID WHERE (ZCRMTAB_ACTIVITY.REF_CUST_NO = @REF_CUST_NO) ORDER BY ZCRMTAB_ACTIVITY.CREATED_AT DESC">
<SelectParameters><asp:QueryStringParameter Name="fieldName" QueryStringField="value" Type="String" />
My problem is that this returns individual row results and are displayed on individual lines. Where the object_id is the same i want all the textual info to be displayed within the same row.
Does anyone know how i can accomplish this?
Thanks in advance

hi, i need help with a query:SELECT Headshot, UserName, HeadshotId FROM tblProfile INNER JOIN Headshots ON Headshots.ProfileId=tblProfile.ProfileId WHERE (UserName= @UserName) this query will select what I want from the database, but the problem is that I have multiple HeadshotIds for each profile, and I only want to select the TOP/highest HeadshotId and get one row foreach headshotId. Is there a way to do that in 1 SQL query? I know how to do it with multiple queries, but im using SqlDataSource and it only permits one. Thanks!

i currently have a table like this..
user_id username app_id app2_id app3_id app4_id
1 john 3 4 5 6
2 mike 4 5 6 6
3 manager 4 5 6 6
4 vicepres 5 6 6 6
5 ceo 6 6 6 6
6 board 6 6 6 6
the basic pattern is... a user has approvers, and those approvers have approvers as well... i have 4 columns of approvers.. and if my first approver is the manager, then my second approver will be the managers approver and my third approver will be the managers approver's approver and so on..
on my actual page, i have select fields for the app, app2, app3, app4 and i need it so that when i change the very first app, it'll automatically update app2, app3, and app4
any ideas how i would do this? im pretty new to sql but im thinking i would use some type of join?
thanks

I have a datatable : Data_Table and a look up table: Lk_table. Myfield that I
use in Inner Join is defined in both the
data and look table.
So I build my query like this:
SELECT * FROM dbo. Data_Table INNER JOIN
dbo. Lk_table ON dbo.Data_Table.MyField = dbo.Lk_table.Myfield
The pb, sometimes I
have myfield still with its default null value in the datatable: Data_Table.
So, I end up getting 0 record when I execute the query shown above.
How do I turn that around so that even if myfield in Data_Table
is Null, I still get the records from Data_Table. (I don t want a set of
records including all possible values from the look up table: Lk_Table)

I'm doing a data conversion with one of my fields (SUMDWK) from one of the tables that will be used in a merge join. With the new, converted field, I do a look up. From this look up, I want to take a new field FiscalWeekOfYear, and replace the original field, SUMDWK. This is necessary because SUMDWK is one of the sorted fields. In the look up, it is not possible to change the Output Alias. Does anybody know a way around this? 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?

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.

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.

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 ?

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
