UPDATE/INSERT To Make One-to-Many Table Become One-to-One
Jul 23, 2005
I have a scenario where two tables are in a One-to-Many relationship
and I need to move the data from the Many table to the One table so
that it becomes a One-to-One relationship.
I need to salvage the records from the many table and without going
into detail, one of the reasons I can't do the opposite as
there are records in the ONE table that I need to keep even if they
don't have any child records in the MANY table.
Below I created the code to create the sample tables:
1- tblProducts is the ONE side table
2- tblProductDetails is the MANY side table
3- tblProductsResult is the RESULT I expect to get after running
some T-SQL code
4- tblProductComponents is another MANY side table to tblProducts
5- tblProductComponentsResult is the RESULT I expect to get...
Some of the points to consider:
6- Normally all UniqueID columns are to be IDENTITY. For
this sample i am entering the UniqueID values myself.
7- I don't want to create new tables like tblProductsResult
and tblProductComponentsResult. I want to update the real tables.
I have created the tblxxxResult tables only for this post.
8- The goal is to update the name of the Product by giving it the
name of the first matching Name from tblProductDetails.
9- If there are more than one entry in tblProductDetails for each
Product, then I need to create new Products inheriting the original
Product's information including its child records from tblProductComponents.
If you run the code and open the tables it will be much clearer
to visually see what I want to achieve.

I actually work in an organisation and we have to find a solution about the data consistancy in the database. our partners use to send details to the organisation and inserted directly in the database, so we want to create a new database as a buffer database to insert informations from the partners then make an update to the main database. is there a better solution instead of that?
Link ( GroupID int , MemberID int ) Member ( MemberID int , MemberName varchar(50), GroupID varchar(255) )
The Link table contains the records showing which Member is in which Group. One particular Member can be in multiple Groups and also a particular Group may have multiple Members.
The Member table contains the Member's ID, Member's Name, and a Group ID field (that will contains comma-separated Groups ID, showing in which Groups the particular Member is in).
We have the Link table ready, and the Member table' with first two fields is also ready. What we have to do now is to fill the GroupID field of the Member table, from the Link Table.
For instance,
Read all the GroupID field from the Link table against a MemberID, make a comma-separated string of the GroupID, then update the GroupID field of the corresponding Member in the Member table.
Please help me with a sql query or procedures that will do this job. I am using SQL SERVER 2000.
table2 is intially populated (basically this will serve as historical table for view); temptable and table2 will are similar except that table2 has two extra columns which are insertdt and updatedt
process: 1. get data from an existing view and insert in temptable 2. truncate/delete contents of table1 3. insert data in table1 by comparing temptable vs table2 (values that exists in temptable but not in table2 will be inserted) 4. insert data in table2 which are not yet present (comparing ID in t2 and temptable) 5. UPDATE table2 whose field/column VALUE is not equal with temptable. (meaning UNMATCHED VALUE)
* for #5 if a value from table2 (historical table) has changed compared to temptable (new result of view) this must be updated as well as the updateddt field value.
We need to Insert/Update a Fact Table from staging Table. currently we are using a SP which update Fact Table for Each region. this process is schedule, every 5 min job is run and Update fact table.but time of Insert and Update too long from staging to Fact, currently we are using merge statement for Insert and update.in my sp we are looping number how many region we need to update and at a time single Region we are updating using while loop in current SP.
I'm importing XML file into DataTable and need to Insert Data into SQL Table. I'm not sure if its posible to take a DataTable with Data and insert into DataAdapter. From there i wanted to update SQL using TableAdapter? Any Tips? Thanks,
This should be easy for someone, but I just can't seem to find a sample to do this.....I have created a table...CREATE TABLE dbo.test ( oId int NOT NULL UNIQUE, test1 varchar(50) NOT NULL PRIMARY KEY )Now, I need to go back and simply add another column to the table such as test2 varchar(50)Not sure if the insert is the way to go and been playing around with various statements but with no luck.Suggestions?Thanks all,Zath
I am new to triggers and need help on the following:
I have a hourly table that inserts new rows every hour but I need to either Insert or Update the daily table with the sum of the reading from the hourly table. If a row exist in the daily table with the date of the hourly table, then I need to update this row but if it doesn't exist, I need to insert this row.
I currently have 2 tables as follows:CREATE TABLE [CRPDTA].[F55MRKT119](mhan8 int,mhac02 varchar(5),mhmot varchar(5),mhupmj int)GOCREATE TABLE [CRPDTA].[F55MRKT11](mdan8 int,mdac02 varchar(5),mdmot varchar(5),mdmail int,mdmag int,mdupmj int)What I would like to do is place a trigger on F55MRKT119 which willinsert records to the F55MRKT11 if they do not exist in that tablebased on the [mdan8] field. If the record does exist I would likeUpdate the corresponding record and increment either the [MDMAIL] orthe [MDMAG] based on the inserted [MHMOT]. What I have so far is asfollows:TRIGGER #1:CREATE TRIGGER trgIns_Summary ON [CRPDTA].[F55MRKT119]FOR INSERTASBEGININSERT INTO CRPDTA.F55MRKT11select INS.MHAN8, INS.MHAC02, INS.MHMOT,case when INS.MHMOT='MAG' then 0 ELSE 1 end,case when INS.MHMOT='MAG' then 1 ELSE 0 end,'0' from INSERTED INSWHERE ins.mhan8 not in(select mdan8 from crpdta.f55MRKT11)ENDTRIGGER #2:CREATE TRIGGER trgUpd_Summary ON [CRPDTA].[F55MRKT119]FOR UpdateASBEGINUPDATE CRPDTA.F55MRKT11SET MDMAIL= case when INS.MHMOT='MAG' then 0+MDMAILwhen INS.MHMOT<>'MAG' then 1+MDMAIL end,MDMAG= case when INS.MHMOT='MAG' then 1+MDMAGwhen INS.MHMOT<>'MAG' then 0+MDMAG endfrom INSERTED INS JOIN CRPDTA.F55MRKT11on(ins.mhan8=mdan8)ENDFor instance if I do the following insert:INSERT INTO CRPDTA.F55MRKT119VALUES('212131','VK4','AL4','0')thenINSERT INTO CRPDTA.F55MRKT119VALUES('212131','VK4','MAG','0')This is what I expect in both tables:[CRPDTA.F55MRKT119] (2 Records)MHAN8 MHAC02 MHMOT MHUPMJ------ ------ ----- ------212131 VK4 AL4 0212131 VK4 MAG 0[CRPDTA.F55MRKT11] (1 Record)MDAN8 MDAC02 MDMOT MDMAIL MDMAG MDUPMJ----- ------ ----- ------ ----- ------212131 VK4 AL4 1 1 0The insert part works fine in that it iserts in both tables with thecorrect values. However it seems as if the Update protion is failingfor some reason. WHat I have tried so far is setting the trigger orderfor the update to run first and vice-versa, but still no luck. Anyhelp would be appreciated.
Hi,Does anyone know of a simple way to do this? I want to create aninsert trigger for a table and if the record already exists based onsome criteria, I want to update the table with the values that arepassed in via the insert trigger without having to use all the 'set'statements for each field (so if we add fields in the future I won'thave to update the trigger). In other words, I want the trigger codeto look something like this:if exists (select * from TableA where Fld1 = inserted.Fld1) then//don't do insert, do an update instead (would i want to rollback here?and will I have access to the 'inserted' table still?)Update TableASet TableA.<all the fields> = Inserted.<all the fields>where Fld1 = inserted.Fld1end ifAny help or ideas would be appreciated.Thanks,Teresa
Just wondering if anyone is aware of a SQL server shareware utility that places a front end on a table to manage insert, update, and delete of rows on a lookup table.
We can certainly write this but before reinventing the wheel I figure I'd ask and see.
A problem has come up in designing a Web page to maintain a small reference table in SQL Server 2000 (9 columns, about 25 records).
I tried to design the Web page to allow INSERT and UPDATE operations using a single page that posts back to itself. The page contains a set of empty form fields for a new record, followed by a set of filled-in form field for each row in the table. The form fields for existing records are given a unique name based on the field name concatenated with the primary key value for that row.
If I set up the page to INSERT only, it works properly. But when I add the fields for existing records, the INSERT operation malfunctions. Specifically, anytime a set of existing fields for a particular column is added to the page, the INSERT will no longer work properly for that column. This is true for all fields except the primary key field. It always INSERTs correctly. I tried adding only some columns to the set of existing form fields. In that case, the INSERT operation added the correct values for the fields that were not listed in the existing records section, but failed for the others.
I am using the INSERT INTO syntax for that operation and the recordset .Update syntax for the edits. I tried using the recordset .AddNew/.Update syntax for the insert, but it exhibited the same problems. The column data types contain smallint, bit, nvarchar, and ntext types.
I know that the correct values are being put into the INSERT statement. I also tried renaming the INSERT form fields to be totally different than the names of the existing record fields. But the problem comes back no matter what.
If necessary, I can split the logic so that inserts and updates are handled by different pages. But I would like to make this work if possible. If a reader knows why SQL Server is causing this problem, any help would be greatly appreciated.

I need to Insert the XML File data into SQL SERVER 2005 db(table). For that I created the table with XML Native column (using typed xml) *********************************create table command************ CREATE TABLE XmlCatalog ( ID INT PRIMARY KEY, Document XML(CONTENT xyz)) *********************************** In order to Create the table with typed xml ,before that we have to create the xml schema which i mentioned below ************************************create schema command******** CREATE XML SCHEMA COLLECTION xyz AS 'Place xml schema file ’ ************************************ I created the xml schema file by using the xmlspy software.
--------------------------Insert command--------- INSERT into XmlCatalog VALUES (1,'copy xml file ‘) ------------------------------- I need to retrieve the xml data from the table ------------select query---------- SELECT Document.query (‘data (/X12//UserId)') AS USERID, Document.query (‘data (/X12/X12_Q1/header/ISA//ISA_Authorization_Information_Qualifier)') AS ISA_Authorization_Information from XmlCatalog. -----------------
I Need to update/insert/delete the xml data in the table
Can you please suggest the procedure to implement the above requirement(insert/update/delete)
I've had little success gooling/searching for this (so far).
Given a simple spreadsheet:
StoreNumber StoreName
1 UPDStoreName_1
2 UPDStoreName_2
3 UPDStoreName_3
4 NEWStoreName_4
I want to have an SSIS package that will update a table: mystores (storenumber int, storename nvarchar(255))
StoreNumber StoreName
1 StoreName_1
2 StoreName_2
3 StoreName_3
5 StoreName_5
.. what I need to do is insert the new, update the existing and leave the remaining unchanged. i.e. :
StoreNumber StoreName
1 UPDStoreName_1
2 UPDStoreName_2
3 UPDStoreName_3
4 NEWStoreName_4
5 StoreName_5
(the UPD and NEW are added to simplify the example).
Now the default action of an excel source into an ole db destination is an insert into the table - so PK constraints causes failures.
Now, given that the table is referred to by other table, and is in a 24x7 website, how do I change the SSIS package such that, on a row-by-row basis, anUpSert (update or insert) is performed?
The only idea I have so far is:
create temp table
insert excel data into temp table
iterate through the table, using if exists ... update else insert logic <-- this to be done in a SP
I have Three tables Student,Daily_Attendance_Master and Daily_Attendence_Details.
I want to run sql of insert or update of student attendence(apsent or present) in Daily_Attendence_Details based on Daily_Attendance_Master_Id and Student_Id(from one roll number to another).
If Both are present in table Daily_Attendence_Details then i want to run Updating of attendance from one roll number to another roll number in Daily_Attendence_Details on the basis of Daily_Attendence_Details_Id
And if both or any one is not present i want to run insert of student attendense from one roll number to another roll number in Daily_Attendence_Details.
I give below the structure of three tables Student,Daily_Attendance_Master and Daily_Attendance_Details.
I have 2 tables (Dept and Emp) The columns in table Dept are Deptno and Deptname. Deptno is bigint and it is primary key. In Emp table, columns are Empno(PK) ,EmpName and Deptno(foreign key referring to Dept)
To Insert or Update record in Emp through application, value of Deptno is coming as 0(Zero). I want the value of Deptno to be inserted or updated as null if the value is Zero (0). How to do this in sql server 2005 by using trigger on table Emp
How to find out that a table has changed. For example if a table has 50K rows, and if any update, insert, or delete was made it should be captured without using any trigger. Is it possible to get such information from any of the system table or DMVs?
I want to be able to duplicate every single record that is inserted or updated in a particular table to another table, but not the delete. Is the best way to set-up a trigger? If so can anyone provide me with an example of how to do this? Also could you just duplicate certain columns in the row I would you have to do all columns?
I'm trying to update (increment) Company.SumtotalLogons from CompanyUsers.NumberOfLogons where CompanyUsers.CompanyID = Company.CompanyID
I'd like to either write a formula (if it is even possible to fire a formula from one table update/insert to increment a field in another table), or a stored procedure that triggers an auto update/append into Company.SumTotalLogons
I know this is possible in access, so i'm wondering how to go about it in ms-sql?
I have been looking for a solution for this for some time and have came up empty handed.
I have 2 servers development box and a live box. Time has passed and my live box has a lot of new data in the database and now I need to update the dev box so I can properly test with real data. Problem here is I want to keep the records that are in the dev box, update them if they exsist on the live box, because live server may or may not contain that record and isert all records that are not on the dev box database.
I hope I am making some sense here, I think I am just making it more difficult then it has to be.
Is it possible to allow a user to insert and update data in a table but prevent them from performing deletes against that same table? For auditing purposes I need to prevent the end users from being able to delete data.
So, I've written an Instead of Trigger to update a foreign key field based on information in another field of the same record.
To add some error handling to the process I updated the Trigger to insert any records that don't have legitimate foreign keys into a second table.
This process works great when I test it by just adding a record using the table view in the SQL Management Studio or through a query run in the query browser.
However, when a record is added via an ODBC connection I get foreign key constraint errors and records are not added to the second table. If the foreign key is legit the record is added and the part of trigger that updates that keyed field executes just fine.
Is anyone aware of this issue? Is there a way around it?
I found the following MSKB article but I'm not sure if it applies to my situation: http://support.microsoft.com/kb/304096
Here's my current code, if that track the problem in anyway:

I am experimenting with using CDC to track user changes in our application database. So far I've done the following:
-- ENABLE CDC ON DV_WRP_TEST USE dv_wrp_test GO EXEC sys.sp_cdc_enable_db GO
-- ENABLE CDC TRACKING ON THE AVA TABLE IN DV_WRP_TEST USE dv_wrp_test
[Code] ....
The results shown above are what I expect to see. My problem occurs when I use our application to update the same column in the same table. The vb.net application passes a Table Valued Parameter to a stored procedure which updates the table. Below is the creation script for the stored proc:
SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO
if exists (select * from sysobjects where id = object_id('dbo.spdv_AVAUpdate') and sysstat & 0xf = 4) drop procedure dbo.spdv_AVAUpdate
[Code] ....
When I look at the results of CDC, instead of operations 3 and 4, I see 1 (DELETE) and 2 (INSERT) for the change that was initiated from the stored procedure:
-- GET CDC RESULTS FOR CHANGES TO AVA TABLE USE dv_wrp_test GO SELECT * FROM cdc.dbo_AVA_CT GO
--RESULTS SHOW OPERATION 1 (DELETE) AND 2 (INSERT) INSTEAD OF 3 AND 4 --__$start_lsn__$end_lsn__$seqval__$operation__$update_maskAvaKeyAvaDescAvaArrKeyAvaSAPAppellationID --0x0031E84F000000740008NULL0x0031E84F00000074000230x02119Test26NULL --0x0031E84F000000740008NULL0x0031E84F00000074000240x02119Test36NULL --0x0031E84F00000098000ANULL0x0031E84F00000098000310x0F119Test36NULL --0x0031E84F00000098000ANULL0x0031E84F00000098000420x0F119Test46NULL
Why this might be happening, and if so, what can be done to correct it? Also, is there any way to get the user id associated with the CDC?
Our system runs a SQL Server 2012 DB, it has a table (table_a) which has over 10M records. Our system have to receive data file from previous system daily which contains approximate 3M updated or new records for table_a. My job is to update table_a with the new data.
The initial solution is:
1 Create a table (table_b) which structur is as the same as table_a
2 Use BCP to import updated records into table_b
3 Remove outdated data in table_a: delete from table_a inner join table_b on table_a.key_fileds = table_b.key_fields
4 Append updated or new data into table_a: insert into table_a select * from table_b
As the test result, this solution is very inefficient. Step 3 costs several hours, e.g. How can I improve it?
I am using SSIS integration between two database. Both databases are sql server 2008. using many integration but getting problem in two only only two integration giving problem, both are executing perfectly and out put also not showing any error.
but destination table not inserted/updated anything.
first issue integration is using data flow task with oledb source and destination. second one is using execute task with for-eachloop container.
I do not insert/update/delete on the view directly.
For every insert/update in table A /B the values should get insert/update in the view respectively. This insert/update on view should invoke the trigger.
And I am unable to see this trigger work on the view if any insert/update occurs on base table level.
Trigger is working only if any operation is done directly on the view.
I am currently working with C and SQL Server 2012. My requirement is to Bulk fetch the records and Insert/Update the same in the other table with some business logic? How do i do this?
there is two similar fields (Size) with the same datatype, I want to make a relation in a way if I change the value in (TableX.Size) the same value will be applied to (TableY.Size).
Hi.We have stored procedure update specific table Each time it run it delete 5000- 6000 rows from table then insert 5000- 6000 rows with different information. It take up to 1 1/2 min execute.
1.Can force Sql server do not make entry for each insert and if yes would it increase speed of procedure ? 2. Is any other way increase speed of insert?
