Transact SQL :: Parent / Child Tables - Pivot Child Data To Parent Row
May 19, 2015Given 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)

If it's the way how it works with MS SQL Server2000, well, IMHO, it's limiting because the above transaction C is avalid one. Or maybe check constraint is not fit for this purpose?Maybe, it doesn't make much sense for me to go into Q2 but I'll try-- create job's child table, taskcreate table #task (taskID int identity(1,1) primary key, taskNamevarchar(25) unique not null, taskEndDate dateTime, taskComplete bitdefault(0), jobID int not null references #job (jobID));-- skip check constraint for taskEndDate and taskComplete for nowNow, the Business Rule says,1) if all tasks are complete then automatically set jobComplete forthe #job table to yes;2) the jobEndDate in the #job table must be >= the last/MaxtaskEndDateI tend to think trigger would slow down data update quite a bit, so,try to stay away for this purpose if possible.Always appreciate your idea.
View 2 Replies View RelatedInsert Data Into Parent And Then Child Tables
Nov 16, 2006hello -
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

SSIS And Parent-Child Relationship Tables
Jun 15, 2006Supose 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.
Copy Parent/child Rows To Same Respective Tables
Feb 29, 2008My 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.
Inserting Data Into Two Tables With Parent-child Relationship
Nov 13, 2006I 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.

Design Question - Parent Child Tables && Identity Columns
Apr 17, 2007I don't know if this is the right forum but...
In a parent/child table structure (order/orderdetail) I have used identity columns for the orderdetail or compund primary keys. I find a single identity column on the detail table easier to manage (with a fk to the parent) but what ends up bieng easiest for the user is to have an order (say #3456) and detail items listed sequentially from 1 to n. This reflects a compound key structure but generating the 2nd field is a pain. Is there any way to tie an identity field to the parent key so that it will generate this number for me automatically?

Parent/Child Table Replication
Apr 4, 2008Hello 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.

View 9 Replies View RelatedUpdate Parent Table With Summation Of Its Child Records
May 24, 2013I 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:
