Returning Parent / Child Rows

Mar 3, 2008

Hi,
I have the following table


JobID JobType JobName ParentJobID etc...
12345 Disconnection MyJob1
98475 New Pilot MyJob2 12345
85746 Streetlight MyJob3 98475




etc

I need a query that returns all the jobs that relate to a specific job

e.g if I pick 12345 I get the following:

12345 Disconnection MyJob1
98475 New Pilot MyJob2
85746 Streetlight MyJob3

As they are all related records.

Can anyone help

Thanks

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'
insert @child select 1, 1, 'AA', '1/1/2015', '3/31/2015'

[Code] .....

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.

Copy Parent/child Rows To Same Respective Tables

Feb 29, 2008

My Question: Does anyone know of a decent way (i.e. I do not want to loop to insert each row and check the SCOPE_IDENTITY() field or anything like that) to copy parent/child rows to their same respective table besides using the method I have listed below (my manager does not really like the idea of the "PreviousID" field)? More details are listed below.



My Table Situation: I have a parent table and a child table. Both tables have an identity column as the primary key. The relationship between the tables is established using the parent table's primary key to the column in the child table that stores the relationship. The identity column in both tables is the only column that is unique in the tables.

Sample Data (made up and simplified for visualization purposes):
ParentTable - "Items"
ID ItemCategory Price
1,T-Shirt,$20
2,Blue Jeans,$50
3,T-Shirt,$40

ChildTable - "Components
ID ItemID Component
1,1,Fabric
2,1,ScreenPrinting
3,2,Fabric
4,2,Zipper
5,3,ThickFabric
6,3,ScreenPrinting
7,3,Elastic

My Need: I need to make a copy of the records (keeping the parent/child relationship intact) to the same table as the source records. For example, in my data example above, I may need to make a copy of all the "T-Shirt" items and their child records. As the parent records are copied, they will be assigned new keys since the primary key is an identity. Obviously, this new key needs to be used when creating the child records, but I need to somehow associate this new key to the new child records.

Possible Solution: I know this can be achieved by adding another column to the parent table to store the "PreviousID" (INT NULL). Using this new field, when I want to copy the "T-Shirt" items, I would insert the new records and store the ID of source records (i.e. the identity value of the row that was copioed would be stored in this "PreviousID" field). Once the parent record has been copied, I could then insert the child records, and I could join on the "PreviousID" field to get to the new ID to use for inserting the copies of the child records.

Thanks for reading this and for any help offered.

Help Needed With Calculating Average For Both Parent And Child Rows

Mar 29, 2008

I am trying to create a SSRS report that needs to show average for both parent and child rows. In the example below i need to show an average of ErrorRecAge column for Company, then for cic_Group and one grand total/avg. How can this be done from single query (as below) and using SSRS built in functions/codes? I am also curious to know if this can be done from TSQL directly (ex. something similar to running sum/total). I appreciate the help.


Select


CustomerCorrection.Id As ParentId,

cc_company As cc_company2,

ccError.Id As ErrorId,

COALESCE(cic_Group,'Other Errors') As cic_Group,

COALESCE(cic_Code,'Unknown') As ErrorCode,COALESCE(cic_Description,'Unknown') As ErrorDescription,

DateDiff(hh,cc_entrydt,getdate())/24.00 AS ErrorRecAge

From


CustomerCorrection Inner Join CCError On

CustomerCorrection.Id = CCError.CustomerCorrectionId

Left Outer Join CustomerImportControl On

cic_code = ce_errno

Where cc_company = 'IWA' And CustomerCorrection.Id In (129,1004,3228)

Order By CustomerCorrection.Id



That Returns
129 IWA 992 Other Errors Unknown Unknown 399.500000
129 IWA 1089 Other Errors Unknown Unknown 399.500000
129 IWA 1760 Other Errors Unknown Unknown 399.500000
1004 IWA 952 Other Errors Unknown Unknown 365.333333
1004 IWA 1853 Other Errors Unknown Unknown 365.333333
3228 IWA 10 Other Errors Unknown Unknown 329.375000

Here is my temp workaround:

Select a.*,b.*

From


(

Select

cc_Company, Count(Distinct CustomerCorrection.Id) as RecCount, Avg(DateDiff(hh,cc_entrydt,getdate()))/24.00 As RecAge

From

CustomerCorrection

Group By cc_Company

) As a

Inner Join


(

Select

cc_company As cc_company2,

COALESCE(cic_Group,'Other Errors') As cic_Group,

Count(Distinct ccError.Id) As ErrorRecCount,

AVG(DateDiff(hh,cc_entrydt,getdate()))/24.00 As ErrorRecAge

From

CustomerCorrection Inner Join CCError On

CustomerCorrection.Id = CCError.CustomerCorrectionId

Left Outer Join CustomerImportControl On

cic_code = ce_errno

Group By cc_company, COALESCE(cic_Group,'Other Errors')

) as b

On a.cc_company = b.cc_company2

Order By cc_Company,cic_group

Parent/Child Rows In Report, Nested Table, Textbox Value In Filter Condition

Mar 26, 2008

Hi All,

I am working on SQL server 2005 Reports.
I have one report, one dataset is assigned to it, and one table which displays it.
Now I come accros requirement that, the column value in the filter condition for the table is present in one textbox.

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

Bcp In Child Before Parent

May 19, 2004

Huh?

I've got good RI data...BUT..a developer loaded the tables in alpha table order....

Such that the child loaded BEFORE the parent....

Huh?

Got a test being set up now to mess with the child file to add a key that doesn't exist in the parent...

But Why is this allowed?

In DB2 you can specify

LOAD DATA REPLACE NO CHECK....

On the load card...you then need to run a check after to verify the data...

Is that what's going on? Is there such a utility in SQL Server to run a check post load?

I'm confused....

Any comments appreciated.

Thanks

Parent Child Transversing

Jul 16, 2005

I have a parent/child relationship in a relational database broken out like this:
Table Name: categories[category_id]         int            (primary_key NOT NULL),[category_name]       varchar(50),[parent_fk]           int
The parent references the category_id in the same table to create the parent/child relationships. I can get all the bottom level categories by doing this:
select category_id, category, parent_fk from categories where  category_id not in (  select parent_fk from categories)
Each bottom-level category has a count attached to it.
The problem I have is getting the counts rolled up for each parent of the bottom level. A parent could/will have multiple bottom-level categories (and counts).
My sql is a little weak, could you help me out?  I can utilize everying in SQL 2000 (stored proc, UDF, anything).
Thanks!

Hierarchy – Parent And Child

Aug 2, 2007

I am designing a table to represent data in hierarchy structure, I use id and parent id to represent the data in hierarchy form:

Id | parent_id
---+-----------
1 | 0
2 | 0
3 | 0
4 | 1
5 | 1
6 | 4
7 | 4
8 | 7
9 | 7


This structure requires complicated queries (recursive call) to find out all the child of a root node, so I have added another field for the root id.
Is this a good relational database design ? kindly suggest.

Id | parent_id | root_id
---+-----------+---------
1 | 0 |
2 | 0 |
3 | 0 |
4 | 1 | 1
5 | 1 | 1
6 | 4 | 1
7 | 4 | 1
8 | 7 | 1
9 | 7 | 1
10 | 2 | 2
11 | 2 | 2
12 | 10 | 2
13 | 10 | 2

Selecting Parent / Child Relationships

Jun 28, 2004

Hello all, I'm having a real hard time trying to figure this one out. I'm trying to create a sql query that selects both the parent name and it's children, but it's got to loop through all the record sets to populate a drop down as an end result.

I think I thought this out correctly:
I have 2 tables

category
relationship

tbl category
cat_id //auto int
cat_name // varchar

relationship
r_id // auto int
parent_id // int
child_id // int

both the parent_id and child_id are associated with the cat_id
in my category table I could have
1cars // this is parent
2 audi
3 bmw
4 chevy

Table data example

r_id parent_id child_id
****************************
1 1 15
2 1 16
3 1 17
4 2 55
5 2 56
etc...
I want to select both the parent cat_name from category and also select the child cat_name where the parent_id = #

I can do it manaully like this
select cat_name, cat_id, parent_id , child_id from category, relationships where child_id = cat_id and parent_id = 1

what is the best way to loop through all the parent ids to find child category?
Could this be done in a stored procedure?

thanks in advance.

Insert Trigger For Parent/Child

May 9, 2006

I am having problems creating a trigger in SQL Server? I have 2 tables (parent and child) with one to many relationship. When I save a record, one row gets inserted in the parent and one to many gets inserted in the child. The trigger is on the parent table and it is trying to select the number of new records just inserted in the child table that meets a certain criteria. Since the transaction hasn't been committed I can not select the number of records from the child. Does anyone know how to handle this? My manager insists this be done in a trigger.

Parent-Child View Without Using Cursors

Jul 26, 2007

I would like to create a View (we'll call it FamilyView) using two tables, that I can then query against.
For example:

Parent
{
ID_PK,
Name,
PhoneNum,
Address
}

Child
{
ID_PK,
ParentID_FK,
Name
}

The view would return a dataset like this:

Parent.Name, Parent.PhoneNum, Parent.Address, Child.Name1, Child.Name2, Child.Name3... Child.NameN

William Smith, (555)555-5555, 123 Main Street, Susie, Peter, Bill Jr, Fred
Jason Jones, (666)666-6666, 54332 South Ave, Brian, Steven
Kay McPeak, (777)777-7777, 9876 Division NW, Kathy, Sally, Karen, Deb, Becky, Kendra, Ann, Edward

with an unknown number of children for each parent.

Then I would like to be able to query against this view with something like this:

SELECT * FROM FamilyView Where Child2 = 'Peter'


I have no idea how to write the SQL for this View. Is it possible?
Is this possible without using a cursor?

Thanks for any advice you all can give me.

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.

Delete Child Records Without A Parent

Oct 12, 2013

I am importing data from a paradox table and trying to clean it up. I have this query that finds all the child records that are not in the parent table.

Select MemberID
FROM memtype AS a
WHERE NOT EXISTS
(SELECT *
FROM members AS b
WHERE a.MemberID IN (b.MemberID));

Now I'm trying to delete all those child records instead of just selecting them so I tried...

Delete MemberID
FROM memtype AS a
WHERE NOT EXISTS
(SELECT *
FROM members AS b
WHERE a.MemberID IN (b.MemberID));

Sql clearly doesn't like this

Union Parent Child Records

Feb 24, 2014

I have an application that has an existing query which returns org units (parent and child) from organization table with orderby on createddate + orgid combination.

Also I added another log table Organization_log with exact columns as Organization table and additional 'IS_DELETED' bool column.

WITH Org_TREE AS (
SELECT *, null as 'IS_DELETED', convert (varchar(4000), convert(varchar(30),CREATED_DT,126) + Org_Id) theorderby
FROM Organization WHERE PARENT_Org_ID IS NULL and case_ID='43333'

[code]...

I need to modify the query:

1. To display the records both from the Organization table and Organization_Log table.
2. The orderby should be sorted on 'Organization Name' asc and it should follow the child order in alpha sort as well.

E.g.:

aaa
==>fff

bbb
==> aaa
==> hhh

Nov 2, 2007

hello there,

I think I might know the answer to this, but I wanted to see if any one has come up with a slick idea for enforcing this relationship. If I have two tables and one is dependent on the other (parent-child relationship), how can I enforce that every parent record has a corresponding child record? Here is a code example


USE tempdb

GO

CREATE TABLE dbo.Parent
(
ParentId int NOT NULL
)

ALTER TABLE dbo.Parent ADD CONSTRAINT PK_Parent PRIMARY KEY CLUSTERED (ParentId)


CREATE TABLE dbo.Child
(
ParentId int NOT NULL
,ChildId int NOT NULL
)

ALTER TABLE dbo.Child ADD CONSTRAINT PK_Child PRIMARY KEY CLUSTERED (ParentId, ChildId)

ALTER TABLE dbo.Child ADD CONSTRAINT FK_Child_Parent FOREIGN KEY (ParentId)
REFERENCES dbo.Parent(ParentId)

INSERT INTO dbo.Parent VALUES (1)
INSERT INTO dbo.Child VALUES (1,1)
INSERT INTO dbo.Parent VALUES (2)
INSERT INTO dbo.Child VALUES (2,2)
INSERT INTO dbo.Child VALUES (2,1)
INSERT INTO dbo.Parent VALUES (3)


SELECT
p.ParentId, 'I SHOULD HAVE A DEPENDENT RECORD'
FROM
dbo.Parent p
LEFT JOIN
dbo.Child c
ON
p.ParentId = c.ParentId
WHERE c.ParentId IS NULL



ParentId 3 should have a child record associated with it. I am assuming that these are my choices:

1) code all inserts to the parent table along with a insert to the child table and wrap those in a transaction

2) place a trigger for insert on the parent table that ensures that the child table is populated after data for the parent.

Here is the gotcha, we will be using a middle-tier data access layer (nhibernate or dlink) so .NET application developers will be creating the data modifications at the transactional level. Also there might be several ongoing ETLs that populate this schema as well, so multiple points of entry and seperate code blocks. I don't want to hide business logic within triggers.

I assume that all our coders are competent and could enforce this properly via code, but I know that mistakes happen. Has any one come across this situation and have a solution for enforcing the integrity of the schema with constraints?
