When creating a new row or record in the Master table (by an Adapter update), how do I then populate new records in 15 different Child tables?
These Child tables are attributes of the Master table. I am sure there is more than one way to do this...
Thanks
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.
hi all, can anyone help me?I am a relative newbie to sql server and I am more familiar withEnterprise Manager than QA. I have made many many access databasesthough. I am making an asp.net application where by there are a setnumber of users, about 80, each one logs in and manages informationwithin their department.To get them started a manager has written 10 different hazards thatwill apply to all of the departments, and he has written consequencesand controls for the hazards. Each department must have thisinformation as each will manage and deal with them differentlyThe hazard information is stored in a main 'hazards' table, and theconsequences and controls are stored in related tables linked by the'hazardID' from the main table to a foreign key 'hazardID' in therelated tablesWhat i want to know is if there is a relatively simple way of using aquery to populate the 10 hazards to each department, and to alsoinclude the related table links, i dont mind renaming the departmentsnames to match each hazard, but i do not want to have to relink therelated tables manuallyIf anyone can give me any advice to get me started i will be incrediblygratefulthank youTable information is belowHazards------------HazardID - identity key fieldHazard - varcharDepartment - varcharConsequences----------------------ConsequenceID - identity key fieldHazardID - FKConsequence - varcharControls------------ControlID - identity key fieldHazardID - FKControl - varchardwight

Was wondering if there is easy anyway to autopopulate a field by pulling a value from a field in the previous record?
For example, I have a table with fields name "Dist_From" and "Dist_To". When I add a new record I would like it to populate the "Dist_From" field with the "Dist_to" value from the previous record.
TIA

Hi,
I have been developing SSIS packages and recently I found a strange thing happening. When executing chilld packages from the parent packages the child packages dont open automatically in the Package Designer window. Hence I cant monitor the places where the errors/ row movement have happened in child pkgs without manually opening the them first and then executing the parent.

I am working with a vendor application called Cisco Unified Attendant Console - it operates on a Windows server with a SQL express database. The CUPs function of the application needs to reference a "contact" field with only the user portion of the contact's email address - generally, the contact's User ID will match the user portion of their email address, however, for this customer it does not (they use the employee number as the User ID and firstname.lastname as user portion of the email address.
Writing a script to accomplish the following:
The dbo.Contact_Properties table of the ATTCFG database has the following fields that we can work with:
- First_Name
- Last_Name
- Email
- User_Field_2
- Contact_Unique_Ref (appears to be the field that ties all other contact tables together ?)
Is it possible to create a script that could run daily to either, combine the First_Name and Last_Name fields (with a period between) and populate the User_Field_2 field for each user, or populate the User_Field_2 field with everything before the @ symbol in the Email field for each user?
Also, by default the servers that this application is installed on does not have SQL Server Management Studio installed - is it possible to accomplish with PowerShell script triggered from the Windows Scheduler?
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 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.

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 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

I have a temporary table (@tblResults) that has 4 columns that need to be populated with a calculation made from columns held within 2 other tables.
Joins
@tblResults tr JOIN dbo.MarketPrice mp
ON tr.Item = mp.Item
AND tr.[Month] = mp.[Month]
AND tr.[Year] = mp.[Year]
AND mp.[Date] BETWEEN tr.LatestStartDate AND tr.PriorEndDate
[code]....
Where the 2 dbo.MarketPrice and dbo.MillDifferentials date fields are NOT equal, the last (chronologically) dbo.MillDifferentials.Diff value should be used (or '0' if no previous value found).
so expected results where @tblResults.Id = 1:
The dbo.MarketPrice.Price value of '2014-10-29' should be combined with the dbo.MillDifferentials.Diff value of '2014-10-06' - this produces the combined Max value of 184.50
The dbo.MarketPrice.Price value of '2014-04-28' should be combined with the dbo.MillDifferentials.Diff value of '2014-04-28'
The dbo.MarketPrice.Price value of '2014-01-22' should be combined with the dbo.MillDifferentials.Diff value of '2014-01-20'
The dbo.MarketPrice.Price value of '2014-01-21' should be combined with the dbo.MillDifferentials.Diff value of '2014-01-20' - this produces the combined Min value of 111.50
The dbo.MarketPrice.Price value of '2014-01-04' should be combined with '0.00' if there is no matching or previous dbo.MillDifferentials.Diff value OR the top 1/max (most recent) dbo.MillDifferentials.Diff value if a record is found before the specified @tblResults.LatestStartDate
