How To Join A Decendent Table On Parent Table Row?

Feb 24, 2006



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.

Omer Kamal

Query Based Off Primary Key Of Parent Table - Adding Child Table

Jan 28, 2012

I need to add a child table that will tell us who the participants counselor is, what I did was I did a Make Table query based off the primary key of the Parent table and made that the link (foreign key) for the People_tbl and the Counselor_tbl, so if the counselor changes then the user adds the record to the counselor tbl and then puts in the Effective date. The problem is that when I run a report it doesn't show the present counselor always shows the old counselor?

Code:
SELECT Student_ind.StudentFirstName, Student_ind.StudentLastName, Student_ind.[Student ID], People_tbl.[Family ID], People_tbl.FirstName,
People_tbl.LastName, People_tbl.[Parent ID]
FROM People_tbl RIGHT OUTER JOIN
Student_ind ON People_tbl.[Family ID] = Student_ind.[Family ID]
WHERE (People_tbl.LastName = @Enter_LastName) AND (People_tbl.FirstName = @Enter_FirstName)

Transact SQL :: Retrieve Currently Created Date From Master Table To Load Into Parent And Child Table

May 12, 2015

In Master tabel i have these date datas

2015-05-10

2015-05-11

2015-05-12

SO when i try to load from  Master table to parent and child table i am using using expresssion like 

select B.ID,A.* FROM FLATFILE_INVENTORY AS A JOIN DMS_INVENTORY AS B ON 
A.ACDealerID=B.DMSDEALERID AND A.StockNumber=B.STOCKNUMBER AND 
A.InventoryDate=B.INVENTORYDATE AND A.VehicleVIN=B.VEHICLEVIN
WHERE convert(date,A.[FtpDate]) = convert(date,GETDATE())  and convert(date,B.Ftpdate) = convert(date,getdate()) ;

If i use this Expression i am getting the current system date data's only  from Master table to parent and child tables.

My Problem is If i do this in my local sserver using the above Expression if i loaded today date and if need to load yesterday date i can change my system date to yesterday date and i can run this Expression.so that yeserday date data alone will get loaded from Master to parent and  child tables.

If i run this expression to remote server  i cannot change the system date in server.

while using this Expression for current date its loads perfectly but when i try to load yesterday data it takes current date date only not the yesterday date data.

What is the Expression on which ever  date i am trying load in  the master table  same date need to loaded in Parent and child table without changing the system Date.

Transact SQL :: Retrieve All Records From Parent Table And Any Records From Child Table

Oct 21, 2015

I am trying to write a query that will retrieve all students of a particular class and also any rows in HomeworkLogLine if they exist (but return null if there is no row). I thought this should be a relatively simple LEFT join but I've tried every possible combination of joins but it's not working.

SELECT
Student.StudentSurname + ', ' + Student.StudentForename AS Fullname,
HomeworkLogLine.HomeworkLogLineTimestamp,
HomeworkLog.HomeworkLogDescription,
ROW_NUMBER() OVER (PARTITION BY HomeworkLogLine.HomeworkLogLineStudentID ORDER BY

[Code] ...

It's only returning two rows (the students where they have a row in the HomeworkLogLine table).

SQL Server 2012 :: Join To Find All Records From One Table That Do Not Exist In Other Table

Apr 29, 2014

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".

Join Table Key To Multiple Table Names

Nov 5, 2004

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.

Thx

Parent/Child Table Replication

Apr 4, 2008

Hello all gurus out there.

I'm an entre level junior programmer. My question is kind of confusing but I'll try to put it as simple as I can.

First we have a main table called "job1". This table consists the order information. The file_id is the unique id and the primary key for this table. This table also pertains other information such as customer data (max limit 5), job data etc. This table is actively (non-stop) used throughout the day.

We have a non-interactive process which will take customers information from the main table and insert into the child table table "jobcust". Jobcust would have file_id, cust, cust_type. For example, if Job1 table had fiel_id=100 and cust1="Tom" and Cust2="David", now Jobcust will have two records file_id, cust1 and file_id,cust2. The main problem is the child table needs to be updated right away and our non-interactive process is good at doing that.. but it is causing a major DATA LATENCY. I would like to ask you all, if you know any better way of doing this without any process.. like in the back end with a trigger/procedure or something like that.

All you help is appreciated.

Thanks much.

Multiple Parent Table Question

Dec 12, 2006

Hi,

I've a question about how to implement a scenario, and would appreciate any suggestions anyone cares to offer.

I'm creating the following tables

FutureContract
Equity

These (and others), may have an option placed on them, I was planning to create seperate option tables for each
i.e.
FutureContractOption
EquityOption

With a FK pointing at the PK of the tables above.

However the data held in the option table looks the same for both, and I'm considering trying to use the same Option table for both the FutureContract & Equity tables.

There is a problem here with the Foreign key referencing the Primary key of the parent table.

I could add two foreign key columns and allow them to be null, so that only one is entered, however we can have an option on a lot of different things, so I might end up with a great list of these columns.
Table - Option
FK - FutureContractPK
FK - EquityPK
I'm using an unique number (identifier) column for the primary key of all tables.

I'm sure this is a relatively common problem, and would be grateful for any suggestions about how I might approach this.

Transact SQL :: Difference Between Inner Join And Left Outer Join In Multi-table Joins?

Oct 8, 2015

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.

Update Parent Table With Summation Of Its Child Records

May 24, 2013

I am trying to update a parent table with a summation of its child records. The child records are being deleted because the transaction has become invalid because payment was made with a bad check or there was a posting error. So a rollback of sorts is required.

Here are is the DDL for the tables and DML for the data:

Code:
DECLARE @t1 TABLE
(
[Year] int NOT NULL,
[Parcel] varchar(13) NOT NULL,
[InterestDateTime] datetime NULL,
[Principal] decimal(12, 2) NULL,
[Penalty] decimal(12, 2) NULL,

[Code] ....

I tried to use a Merge statement with an ON MATCH for each TransType, but it complained that I could not have multiple update statements. OK. So I tried a MERGE with single update statement with a case and it complained that I was updating the same parent multiple times, which I was and want to! So, I tried the following update statement and it still does not work, though no error message.

Code:
update t1 set
t1.Principal = t1.Principal + (case when t2.TransType = 'R' then t2.Payment else 0 end),
t1.Penalty = t1.Penalty + (case when t2.TransType = 'P' then t2.Payment else 0 end),
t1.Interest = t1.Interest + (case when t2.TransType = 'I' then t2.Payment else 0 end)
from @t1 t1
inner join @t2 t2 on t2.YEAR = t1.YEAR and t2.Parcel = t1.Parcel

I am expecting the following after the update:

Code:
Select * from @t1

201200000018092013-03-14 00:00:00.000 211.15 10.00 3.14

I have a table called "College". In a table, I have to create a structure for multilevel parent-child relationship

For Example,

1) State has number of colleges, Number of colleges has Number of dept. , Number of dept. has no. of subjects, no. of subject has number of chapters and the hierarchy goes on.

Expected Output is,
College 1
Dept 1
subject 1

subject 3
Dept 2
Dept 3

I tried in so many ways, I do not know how to query in single table.

Trigger In Child Table That Required Parent Info

Aug 5, 2007

Hi,
I have tables parent - PurchaseInvoices and child - PurchaseInvoiceDetails. I have trigger in PurchaseInvoiceDetails that would update stock qty based on Location code stored in parent table - PurchaseInvoices upon INSERT/UPDATE/DELETE.

I also set table RI to have cascade delete. I faced problem that, when I delete record in parent table, it would cascade delete child table. Trigger in child table fired and try to update stock qty. However, in this case, trigger unable to locate parent table record anymore.

How to overcome this? I can't move my stock update code to other place since I got to update stock if any changes happen to child table.

Please advice.
