Stored Procedure : How To Output Parent Child Etc Data
Mar 9, 2006
Q: How to Output Parent Child Data using 2, 3 or more related tables.
say you have 3 related tables where the Bold HouseID is the one to many relationship
Houses
HouseID
Name
add1
HouseOwer
AutoID
HouseID
Name
add1
HouseCorrespondent
AutoID
HouseID
Name
add1
Loop For each HouseID
step through the database
first get the ParentID from the Houses table
return that data
then get the related from the house owners table
return that data
then get the related correspondents from the House Correspondent table
return that data
end loop
ie return the date like below
Code:
HouseID | Name | add1
1 House1 abc Address
1 Mr abc Mr abc Ower Address
1 Mr abc Mr abc Correspondent Address
2 House2 def Address
2 Mr def Mr def Ower Address
2 Mr def Mr def Correspondent Address
3 House3 ghi Address
3 Mr ghi Mr ghi Ower Address
I hope ive explained well enough

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] .....

If match, extract matching records for that Category from Both Tables (Categories.CategoryID, Products.ProductName, Products.QuantityPerUnit) and e-mail them based on E-Mail Address from Parent (Categories ) Table. If no E-Mail Address is listed, do not create output file. In this instance Category Id = 3.Basically I want to select 1st record from Parent Table (Here is Category) and search for all matching Products in Products Table. And Create an E-mail and sending just those matching records. Repeat the same process for remaining rows from Categories Table. I am expecting my E-Mail Output like this: For Category Id: 1

12 - 12 oz jarsI am not extracting the Data for any user Interface (ie. Grid View/Form View Etc). I will just create a Command Button in an ASP.NET 2.0 form to extract Data. My Tables are in SQL 2005. I was thinking to read the Category records in a Data Reader and within the While Loop, call a SP to retrieve the matching records from Products Table. If matching records found, call System SP_Mail to send the E-mail. The drawback with that for every category records (Within While Loop) I need to call my SP to get Products Data. Will be OVERKILL? Ideally I would like extract my records with one call to a SP. Is there any way I can run a while loop inside the SP and extract Child Data based on Parent Record? Any Help or sample URL, Tutorial Page will be appreciated. Thanks

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)
INSERT INTO @DATA VALUES (1, 'Design', '06/15/2015', 2, NULL), (1, 'Plan', '06/01/2015', 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)
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'
UNION ALL SELECT 1, 'Design', '06/15/2015', 2, NULL UNION ALL SELECT 2, 'Plan', '06/20/2015', 1, NULL UNION ALL SELECT 2, 'Design', '06/25/2015', 2, NULL

I'm trying to use the Ratio to Parent sproc - [URL] .... The problem is that the stored proc appears to be pegged at 4 decimal places (which translates to ##.##%). This is losing precision and isn't adding up to 100% when the ratios are summed individually.
Can this be fixed within SSAS or will i need to modify the assp code? .NET decimals are meant to automagically scale, so not sure why it's coming out as (5,4) but my .net coding knowledge is fairly poor.I get the correct behaviour if hardcode a ratio to parent MDX calc (the resulting ratio has as many decimal points as are required)

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

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))
INSERT INTO @DATA (DataId, DataName, DataDate, ParentDataName)
VALUES (1, 'child plan 1', '2015-06-09', 'Plan'), (1, 'child plan 2', '2015-06-08', 'Plan'),
(1, 'Design', '2015-06-01', NULL), (1, 'Implement', '2015-06-01', NULL),
(1, 'child Implement 1', '2015-06-09', 'Implement'), (1, 'child Implement 2', '2015-06-10', 'Implement'),
(1, 'Plan', '2015-06-01', NULL), (1, 'Operate', '2015-06-01', NULL)
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,

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'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 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.

I am working on an OLAP modeled database.
I have a Lookup Transformation that matches the natural key of a dimension member and returns the dimension key for that member (surrogate key pipeline stuff).
I am using an OLE DB Command as the Error flow of the Lookup Transformation to insert an "Inferred Member" (new row) into a dimension table if the Lookup fails.
The OLE DB Command calls a stored procedure (dbo.InsertNewDimensionMember) that inserts the new member and returns the key of the new member (using scope_identity) as an output.
What is the syntax in the SQL Command line of the OLE DB Command Transformation to set the output of the stored procedure as an Output Column?
I know that I can 1) add a second Lookup with "Enable memory restriction" on (no caching) in the Success data flow after the OLE DB Command, 2) find the newly inserted member, and 3) Union both Lookup results together, but this is a large dimension table (several million rows) and searching for the newly inserted dimension member seems excessive, especially since I have the ID I want returned as output from the stored procedure that inserted it.
Thanks in advance for any assistance you can provide.

I am using execute sql task to run a stored procedure in oracle database which returns a resultset. This works. Now I need to send the ouput to a destination table in a sql database. Should I use for each loop to pick the resultset and insert it into the destination one by one (which I dont think is a great idea) or is there a better way to accomplish this task (in data flow task) ?
When I use dataflow task instead of execute sql task, the main issue is I am not able to see the output columns when I execute an oracle stored procedure, but when I see the preview I can see the resultset . But I can see the output columns for a sql server stored procedure.

I have a stored procedure 'ChangeUser' in which there is a call to another stored procedure 'LogChange'. The transaction is started in 'ChangeUser'. and the last statement in the transaction is 'EXEC LogChange @p1, @p2'. My questions is if it would be correct to check in 'LogChange' the following about this transaction: 'IF @@trancount >0 BEGIN Rollback tran' END Else BEGIN Commit END.
Any help on this would be appreciated.

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

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

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.
Brian

select 3 as GroupId,'IBM' as GroupName,0 as IdParentGroup union all
select 4 as GroupId,'SunMicrosystem' as GroupName,1 as IdParentGroup union all
select 5 as GroupId,'peoplesoft' as GroupName,1 as IdParentGroup union all
select 6 as GroupId,'mysql' as GroupName,1 as IdParentGroup union all
select 7 as GroupId,'Nokia' as GroupName,2 as IdParentGroup union all
select 8 as GroupId,'EShop' as GroupName,2 as IdParentGroup union all
select 9 as GroupId,'Meiosys' as GroupName,3 as IdParentGroup union all
select 10 as GroupId,'UrbanCode' as GroupName,3 as IdParentGroup )
select * from groups;
Expected result:
Code:
with ExpectedResult as (
select 'Oracle' as GroupName,'SunMicrosystem' as SubGroup union all
select '' as GroupName,'peoplesoft' as SubGroup union all
select '' as GroupName,'mysql' as SubGroup union all
select 'Microsoft' as GroupName,'Nokia' as SubGroup union all
select '' as GroupName,'EShop' as SubGroup union all
select 'IBM' as GroupName,'Meiosys' as SubGroup union all
select '' as GroupName,'UrbanCode' as SubGroup )
select * from ExpectedResult;
some sample query to how to achieve this parent-child has the same table.

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.

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
