Parent | Child Relationship And Showing Tree

Aug 3, 1999

Hi!

I am new to SQL Server and am starting to learn. Here is an issue I have not solved yet:

If I have a table with an CompanyID, Parent ID, Child ID and CompanyName and given a CompanyID, how would I (using a stored procedure I imagine) provide a Tree Structure of the company and all it's descendants?

Also, how would I show it's ancestry?

Company1
subsidary1 > subsidary1's child
subsidary2 > it's children, etc...etc...

I hope I phrased the questions right.

Thanks for your help!

Need To Insert Parent/child Relationship Rows Into DB

Oct 18, 2006

Hi

I need to read a file and write parent/child relationship rows. I cannot seem to fugure out how I can generate keys that I an use for the relationship.

I looked at using a variable, but have no joy - I cannot instantiate the variable and it errors - notsure wy.

I also looked to see if I can write to a DB table that maintains key id, but not sure how to do that.

I alo thought of setting up the parent table key to be auto-increment,but canot see how I can read this so that I can us it in the child row inserts.

Help will be really appriciated

Thanks in advance.

Parent Child Relationship Column Hint?

Feb 22, 2007

I've got a dilemma which I hope someone has a solution to.

Let's say we're building a data mining model to predict aircraft reliability. In the training table we've got a column (among many others) with a unique aircraft ID, and then a column for the type (737,747) and then a column for the series (100,200,300). I.E. A 737-800 series would be "737" and "800".

There is in essence a parent-child relationship between these 2 columns. 737's should share a common set of reliability factors, and then those factors might be further defined by the series number (for instance, the 737 might have very reliable radar except for the 500 series). The series is analogous to what model year a car is. What I want to make sure doesn't happen is for the system to correlate a 747-400 and a 737-400 because they are the same series. They are totally independent if the model number is different.

My only idea was to merge the columns and have a single value "737-100". But it would seem then that the model won't have any idea that a "737-100" and "737-200" should have a lot more in common than a "737-100" because the values will be completely different.

I was hoping to find some sort of parent-child hint in the column properties but found none.

What solutions have other people tried? It sure seems that there should be an elegant solution for something like, but I'm missing it.

SSIS And Parent-Child Relationship Tables

Jun 15, 2006

Supose I have two records in a parent-child relationsuip (actually I have many more such records). Does SSIS offer any support ask for inserting one record into the parent table, the other into the child table, and updating the foreign key of the child to point to the parent?

TIA,

Barkingdog

P.S. I have to do just this as part of the datawarehouse test I'm running. Seems like a common task but I don't recall anything in SSIS addressing the issue.

Inserting Data Into Two Tables With Parent-child Relationship

Nov 13, 2006

I am trying to insert data into two tables with a SSIS package. One table has a foreign key relationship to the other table's primary key. When I try to run the package, the package will just seems to hang up in bids. I have found two ways around the issue but I don't like either approach. Is there a way to set which table gets insert first?

If I uncheck the check constraints option on the child table, the package will run very quickly but this option alters the child table and basically disables the constraint. I don't like this option because it is altering the database.

The second approach is to set the commit level on both tables to say 10,000 and make sure that the multicast component has the first output path moved to the parent table. I don't like this option because I am not sure if the records are backed out if the package should abend after records have been committed.

Transact SQL :: Parent / Child Tables - Pivot Child Data To Parent Row

May 19, 2015

Given the sample data and query below, I would like to know if it is possible to have the outcome be a single row, with the ChildTypeId, c.StartDate, c.EndDate being contained in the parent row.  So, the outcome I'm hoping for based on the data below for ParentId = 1 would be:

1 2015-01-01 2015-12-31 AA 2015-01-01 2015-03-31 BB 2016-01-01 2016-03-31 CC 2017-01-01 2017-03-31 DD 2017-01-01 2017-03-31

declare @parent table (Id int not null primary key, StartDate date, EndDate date)
declare @child table (Id int not null primary key, ParentId int not null, ChildTypeId char(2) not null, StartDate date, EndDate date)
insert @parent select 1, '1/1/2015', '12/31/2015'

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.

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.

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

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.

How To Postpone Trigger Fire Until After Both Parent And Child Table Values Have Been Inserted

Feb 13, 2008



Hi all,

I am sure someone must have run into this before. I have a couple of tables with a parent child relationship.

I created a trigger on the insert of the parent but don't want it to fire until both the parent and child have been inserted into.

However sometimes the child may not get inserted in to at all. In other words it is a 1 to 0 or more relationship.

I created the whole insert into the parent and the child and wrapped it all up in a transaction hoping that the trigger would not fire until the transaction actually completed.

However such is not the case and it fires when the parent is inserted into but nothing is inserted into the child yet even though that is part of the transaction.

Is it possible to postpone trigger fire until after both parent and child table values have been inserted?

Thank you,
John

I can not use textbox i.e. reportItems in filter condition. Can someone suggest me how to use textbox value in filters?


I want to display parent/child records on report. I am not getting the proper solution.

The data is like this:

Sequence ItemCode IsParent

1 XYZ 0 'do not have child record

2 PQR 1 'have child records with sequence no 3

3 ASD 0

3 AFDGE 0

3 VDC 0

4 ASR 1 'have child records with sequence no 5
5 ASR 0

If IsParent = 1, that record has child records with sequence = parent sequenece + 1



I think u can understand the data I need to bind, and it is like:

XYZ

+ PQR

ASD

AFDGE

VDC

ASR

On + click we can do show/hide of child records.

I m not getting how to achive this in SQL server report. Can u give some hint?

Thanks in advance

---Try to obtain the LEFT OUTER JOIN Results for the Parent-Child Table

SELECT * FROM Person AS I LEFT OUTER JOIN Book ON I.ID=P.ID

GO

////---Results---//////

Msg 156, Level 15, State 1, Line 5

Incorrect syntax near the keyword 'NOT'.

////////////////////////////////////////////////////

(1) Where did I do wrong and cause the Error Message 156?

(2) I try to get a Parent-Child table by using the LEFT OUTER JOIN via the following code statement:

Msg 156, Level 15, State 1, Line 5

Incorrect syntax near the keyword 'NOT'.

Can I get a Parent-Child table after the error 156 is resolved?

Please help and advise.

Thanks,

Scott Chang
