Transact SQL :: Parent Child Data With Different Order By Clause?
Jun 24, 2015
I'm asking my previous question in this new thread with more specific data and condition.I have below sample data,
DECLARE @DATA TABLE (U_ID INT, U_NM NVARCHAR(20), U_DT DATE, U_ORD INT, P_U_NM NVARCHAR(20) NULL)
INSERT INTO @DATA VALUES (1, 'Design', '06/15/2015', 2, NULL), (1, 'Plan', '07/01/2015', 1, NULL), (1, 'Cust Plan 1', '06/10/2015', 0, 'Plan'), (1, 'Cust Plan 2', '06/05/2015', 0, 'Plan'),
(2, 'Design', '06/25/2015', 2, NULL), (2, 'Plan', '06/20/2015', 1, NULL)
We have 2 different U_ID (1, 2) and I want a SELECT query to display,
1. For U_ID = 1, we have 2 parent U_NM (Design & Plan) and Plan having 2 child (Cust Plan 1 & Cust Plan 2).
2. I want to display parent U_NM ORDER BY U_ORD
3. If any parent having child element, then need to show immediately under that parent and ORDER BY U_DT
4. For U_ID = 2, we don't have any child, hence display ORDER BY U_ORD

I have a table with below kind of data,
DECLARE @TBL TABLE (ItemId INT IDENTITY(1,1), ItemName NVARCHAR(20), ItemDate DATE, ParentItemName NVARCHAR(20), ItemOrder INT, ReportId INT)
INSERT INTO @TBL (ItemName, ItemDate, ParentItemName, ItemOrder, ReportId)
VALUES ('Plan', '2015-06-01', NULL, 1, 20),('Design', '2015-06-01', NULL, 2, 20),('Test', '2015-06-20', NULL, 3, 20),('Complete', '2015-06-30', NULL, 4, 20),
('Design child A', '2015-06-02', 'Design', 1, 20), ('Design child B', '2015-06-01', 'Design', 2, 20),
('Test child A', '2015-06-10', 'Test', 1, 20), ('Test child B', '2015-06-09', 'Test', 2, 20), ('Test child C', '2015-06-08', 'Test', 3, 20),
('Test grand child A', '2015-06-08', 'Test child B', 1, 20), ('Test grand child B', '2015-06-08', 'Test child B', 2, 20)
select * from @TBL
Here I want,
1. to display all parent with ORDER BY ItemOrder (no need to sort by ItemDate)
2. display all child row right after their parent (ORDER BY ItemOrder if ItemDate are same, else ORDER BY ItemDate)
3. display all grand child row right after their parent (ORDER BY ItemOrder if ItemDate are same, else ORDER BY ItemDate)
Looking for below output ...

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] .....

I have used Aasim Abdullah's (below link) stored procedure for dynamically generate code for deletion of child tables based on parent with certain filter condition. But I am getting a output which is not proper (Query 1). I would like to have output mentioned in Query 2.
Link: [URL]
--[Patient] is the Parent table, [Case] is child table and [ChartInstanceCase] is grand child
--When I am deleting a grand child table, it should be linked to child table first followed by Parent
--- Query 1
DELETE Top(100000) FROM [dbo].[ChartInstanceCase]
FROM [dbo].[Patient] INNER JOIN [dbo].[Case] ON [Patient].[PatientID] = [Case].[PatientID]

I have a table with parent child relationship data.
DECLARE @DATA TABLE (U_ID INT, U_NM NVARCHAR(20), U_DT DATE, U_ORD INT, P_U_NM NVARCHAR(20) NULL)

SELECT * FROM @DATA
1. For U_ID = 1, we have two diffrent U_NM and for one U_NM we have 2 child data. Need to show parent data order by U_ORD and need to show child data within their parent order by U_DT
2. For U_ID = 2, we don't have child data, hence need to show data order by U_ORD only
SELECT 1 AS U_ID, 'Plan' AS U_NM, '06/01/2015' AS U_DT, 1 AS U_ORD, NULL AS P_U_NM
UNION ALL SELECT 1, 'Cust Plan 2', '06/05/2015', 0, 'Plan' UNION ALL SELECT 1, 'Cust Plan 1', '06/10/2015', 0, 'Plan'

I would like to display child row right after parent row with ORDER BY DataDate for below set of data.
DECLARE @DATA TABLE (DataUID INT PRIMARY KEY IDENTITY(1,1), DataId INT, DataName NVARCHAR(20), DataDate DATE, ParentDataName NVARCHAR(20))

select * from @DATA
1. as a example the child row 'child implement 1' & 'child implement 1' show correctly under parent 'Implement' with Order BY DataDate.
2. I'm looking for a SELECT query which should display 'child plan 1' & 'child plan 2' under parent 'Plan' with Order BY DataDate clause.
Below is the expected output I'm looking for,

I have a table as below
ItemID ParentID
6 NULL
7 NULL
8 7
11 7
12 8
Here ParentID null means it does not have the parent its the master. I want result in below format.
ItemID ParentID
6 NULL
--No parent no child
7 NULL
--No parent but has child
8 7
--7 is the parent of 8
12 8
--8 is the parent
11 7
--7 is the parent
Basically it should be in parent id then child id after that child's childID , In a recursive way.

I have a Recursive CTE for TFS database which gives me below results:
Parent (User Story) level 0
-------------.Task(Dev) and ask(QA) --
level 1
BUG level 2
---------------Task (Dev) and Task(QA)
level2
So, My ParentID column keeps two ParentId one for User story which keeps the child tasks and child bugs and another for Bug Child tasks
I need to update this results and want to see all of the tasks under User story so the result I want is:
User Story:
Task(dev and QA)
Task (Dev and QA ) but its should know that these tasks are the bug tasks.

I have a single complex query.
SELECT
Col1, -- Header,
Col2, -- Header,
Col3, -- Detail
Col4, -- Detail
Col5, -- Detail
FROM
TableName;
The query repeats the Header row value for all children associated with the header.I need the output of the query in XML format such that..For every Header element in the XML, all its children should come under that header element//I am using -
SELECT
Cols
FROM
Table Names
FOR XML PATH ('Header'), root('root') , ELEMENTS XSINIL
This still repeats the header for each detail (in the XML) , but I need all children for a header under it.I basically want my output in this format -
<Header >
<detail 1>
</detail 1>
<Detail 2>
</Detail 2>
<detail 3>
</detail 3>
</Header>

UNION ALL
SELECT t1.[ParentID],T1.Value, FROM DynamicColsValues_TP1 t1 INNER JOIN Parent t2
ON t1.[ParentID]=t2.[ParentID]
)
SELECT * FROM Parent option (maxrecursion 0)
When I execute this code. It is returning me millions of rows. Whereas i have only 20 rows in a table max 40 rows it should return.

I am working on an ASP.NET site to display information about authors and books. I'm working on the Author page right now and I'm having trouble getting it to display the data I want.
I'm trying to do everything with declarative controls and as little code-behind as possible.
I have a datasource on the main page that selects the Author data and provides this to a FormView. Inside the FormView is another datasource that takes the AuthorID as a parameter and selects the list of books, which is provided to a DataList.
Inside the DataList I display some limited Book information. I also want to display some child items of the Book (grandchildren of the author), for example other authors who contributed to that book, or alternative titles. I have tried using datasources in each DataList row with a parameter set to the BookID, and it works just great, but the response time is just not acceptable. Each datasource of possible several dozen is making its own call to the database and it's just too slow.
If I use code I can grab all the data in one operation and use relations in the DataBinding event (I believe) to select the data I want, but this is a bit cumbersome and I expect will cause trouble if I want to eventually use an ObjectDataSource.
Incidentally, on a display-only page I use the XMLDataSource and it works great, but I need read-write access on the Edit page.
Is there a good way to do what I'm trying to do?
Thanks,
Graham

hello -
i am trying to figure out how i can create an SSIS package to insert into multiple tables. After the first insert, I want to take the ID created (an Identity column) and then use that to insert into other associated (foreign key) tables.
For example, I have a table Users. The primary key is an Identity column. Once the SSIS insert is complete, the bulk load of new users has an identity ID value for each row. What I want to do, during the same SSIS package, is to take each row as it is inserted and add rows to other tables. Like, UserDepartment - it has a foreign key for the user id and a foreign key to the department being added. And, as part of this I will need to get the latest ID value and possibly some other values and store them in variables.
I looked at multi-cast, but I don't know/think that this will work for me.
does anyone know of a good example or article like this?
thanks
- will

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.

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.

In SQL 2012.A query that joins 2 table, with order by clause doesn't get sorted and the result set is not ordered. This happens when some of the columns in the where criteria are in a unique index which is the index that is used for the join between the 2 tables, and all the columns in the unique index are in the where criteria.In the query plan there is no component for sort.The work around was to drop the unique index, or change it to a non-unique index. Once this was done, the execution plan was changed to add the sort component (even when the index was changed to non-unique and the join was still using this index).

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

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

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

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!

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

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.

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.
Thanks, James
