How To Update Child Table Using The PK And A Seq #
Jun 17, 2002
Good morning,
I have two tables PARENTTBL which is a parent table and CHILDTBL which is a
Child table . For each insert in the Parent table i want to insert values in the child Table but (when inserting in child table) i want the Field FILED2 which is a varchar one will receive the value of the PKEY int cancatenated with a sequnetial value for each new PKEY
FILED2 = Rtrim(LTreim(Str(PKEY))+ Sequential # . which is a
Sequential # by PKEY value .
Exemple : If i insert
100,A,B in PARENTTBL (100 is a PK value)
i want to insert in CHILDTBL the following data :
125,100-1
126,100-2
300,100-3
452,100-4
The first column is the Child PK and the second column is the FILED2
I want to do this in one insert instead of insert then Update.
I don't find the equivalent of Number(*) of SYBASE or ROWNUM of Oracle in order to do This .
I 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 have table "Clients" who have associated records in table "Mailings" I want to populate a gridview using a single query that grabs all the info I need so that I may utilize the gridview's built in sorting. I'm trying to return records containing the next upcoming mailing for each client.
The closest I can get is below: I'm using GROUP BY because it allows me to return a single record for each client and the MIN part allows me to return the associated record in the mailings table for each client that contains the next upcoming 'send_date'
SELECT MIN(dbo.tbl_clients.client_last_name) AS exp_last_name, MIN(dbo.tbl_mailings.send_date) AS exp_send_date, MIN(dbo.tbl_mailings.user_id) AS exp_user_id, dbo.tbl_clients.client_id, MIN(dbo.tbl_mailings.mailing_id) AS exp_mailing_idFROM dbo.tbl_clients INNER JOIN dbo.tbl_mailings ON dbo.tbl_clients.client_id = dbo.tbl_mailings.client_idWHERE (dbo.tbl_mailings.user_id = 1000)GROUP BY dbo.tbl_clients.client_id The user_id set at 1000 part is what makes it rightly pull in all clients for a particular user. Problem is, by using the GROUP BY statement I'm just getting the lowest 'mailing_id' number and NOT the actual entry associated with mailing item I want to return. Same goes for the last_name field. Perhaps I need to have a subquery within my WHERE clause?Or am I barking up the wrong tree entirely..
I have table1 which has many unique ID numbers and table2 that has many records for each ID. some of the ID numbers in table1 have changed and I have created a translation table (table3) that links the old and new ID numbers.
What I need to do is some sort of update sql statement that updates all the records in table2 changing all the oldID numbers to the new ones using the translation table.
Table1 and table2 are not linked...can anyone help me with the sql statement
example
Table 1 IDNUM NAME 12345 Joe 12346 Mary 12347 David
Hi all, I have a gridview bound with a SQLDataSource. I am using the Update feature of the SQLDataSource to update a SQL Server database with values entered into the gridview. However I am not getting it to work. I believe this is due to the controls that contain the user entries are not the gridview itself, but rather child controls within the gridview. I have been using the names of the actual controls but nothing happens. Upon submit, the screen returns blank, and the database is not updated. Here is some code:
As seen above, controls such as txtPrimarySettlement are referenced but the update is not successful. The text boxes are within the GridEditSettlement gridview. In the .aspx code I cannot use FindControl (at least I don't think it will work). So the questions are: Is it possible to reference the child controls, if so - how? Is there another way to do this, such as in the vb code behind - in the either the gridview's RowUpdating event or the SQLDataSource's Updating event. What is the best approach? Anyone come up against this issue before? Thanks, KB
Here, 1. for all ReportId, child items's ItemOrder = 0 2. example, for ReportId = 5, both child items ("Item1-Child1" & "Item1-Child1") of parent "Item1" has ItemOrder = 0
I need to, 1. update all child items with ascending numbers starts with 1 against each parent and each report. 2. for each different parent or different report, order by should starts with 1 again.
In SQL Server 2000, I have a parent table with a cascade update to a child table. I want to add a record to the child table whenever I add a table to the parent table. Thanks
I need to add a child table that will tell us who the participants counselor is, what I did was I did a Make Table query based off the primary key of the Parent table and made that the link (foreign key) for the People_tbl and the Counselor_tbl, so if the counselor changes then the user adds the record to the counselor tbl and then puts in the Effective date. The problem is that when I run a report it doesn't show the present counselor always shows the old counselor?
Code: SELECT Student_ind.StudentFirstName, Student_ind.StudentLastName, Student_ind.[Student ID], People_tbl.[Family ID], People_tbl.FirstName, People_tbl.LastName, People_tbl.[Parent ID] FROM People_tbl RIGHT OUTER JOIN Student_ind ON People_tbl.[Family ID] = Student_ind.[Family ID] WHERE (People_tbl.LastName = @Enter_LastName) AND (People_tbl.FirstName = @Enter_FirstName)
I have two tables that are related by keys. For instance,Table employee {last_name char(40) not null,first_name char(40) not null,department_name char(40) not null,age int not null,...}Employee table has a primary key (combination of last_name and first_name).Table address {last_name char(40) not null,first_name char(40) not null,street char(200) not null,city char(100) not null,...}Address table has a primary key (combination of last_name, first_name andstreet in which (last_name, first_name) reference (last_name, first_name) inemployee table.Now I want to delete some rows in Address table based on department_name inEmployee table. What is sql for this delete?I appreciate your help. Please ignore table design and I just use it for myproblem illustration.Jim
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.

Create Table UserStatus ( UserId int, Date datetime, StatusId int )
Create Table Status ( StatusId int Status nvarchar(50) )
A user will go through all Status one by one. (1) Registered -> (2) In progress -> (3) authorized. Now I want to know which users are in progress (2) but a simple select statement like:
Select LastName from Users Inner Join Users.UsersId = UserStatus.UserId Where UsersStatus.StatusId = 2
Will not return the wanted records because all authorized Users have been in this status.
I hope you understand the problem and can help me out.

some sample query to how to achieve this parent-child has the same table.
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.
I have a single table which holds a hierarchical a structure. I would like to get all the child ID's from one Stored Proc call. For example I give it an ID in the structure and I would like to give me all the child records that exist to the lowest level for each category found
My table structure is [SvcID] [varchar](30) NOT NULL, [Ser_SvcID] [varchar](30) NULL, [SvcDesc] [varchar](100) NOT NULL
I know where the root of the hierarchy is because Ser_SvcID will be null. Im not sure how to do this in one stored procedure call
how can we delete parent table as well as child table using a single query applied on parent table, can someone please help me onn this topic? it will be very nice of you guys.
so if i give input say categoryid=1[This falls under main category-boxing] i need to get result as 1 boxing [main category] 4 mayweather [sub category] 5 tyson [sub category] 6 clinton woods [sub category]
if i give categoryid=5[Note:Tyson] result should be as 1 boxing [main category] 5 tyson [sub category]
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
I want to create a 1-many relationship. Parent table has a primarykey, child table has no primary key. The child table does have anindex with all four fields of the parent's PK. How can I do this?Thanks, Bob C.
I have a situation here. Please advice me on this.
I have a master table and a child table. They have a PK and FK relationship. The master table has an identity column with auto increment set to true. This map as a FK in the child table. My questions are:
Can I have a single form to insert a new record into master and child table at the same time?This has to be accomplished without stored procedures. Can it be done?Is it possible to do this with a single insert query? If yes, can it be done with sql data source or dataset or tableadapters’?Please point me towards appropriate link for doing so.
The problem of mine is, I have a datagrid, Which displays data from a Employee(parent) table. Now I want to delete some records based on the user selected checkbox,only those records which has no related records in the EmployeeProject(child) can be deleted.I want to know which are all the record that cannot be deleted? How can I achieve this?
hi, i have two tables with parent/child relationship - pipeline and pipelineStatus. the select statement like this:
SELECT * FROM pipeline INNER JOIN pipelineStatus ON pipeline.id = pipelineStatus.parentID
i got multiple records for each pipeline.id because of multiple records of pipelineStatus. Is it possible to get only one record for each pipeline.id with last record of pipelineStatus table? (stored procedure ok)

How to achieve this parent-child has the same table.
Should I change my current design which has a Lookup Child Table and a Parent Table containing a ID link tot he Child Table, and instead just putting a varchar for the Value in the Parent Table?
The issue is that the value is unique for a large percentage of cases (although some specific values reoccur very frequently).
However, the parent table has a high number of inserts, and that in turn often requires inserts to the Child Table, which in turn pushes the Child Table out of shape, and performance suffers.
The data is very seldom used (usually for debugging only)
Should I de-Normalise this for performance?
Details of the actual circumstances:
I have a table that Logs each "page hit" on our web site. That stores the "Referrer".
We store the Referrer for the SESSION separately (the first page viewed will have an external referrer, thereafter all pages will have an "internal" referrer).
This Referrer data is used VERY LITTLE - just for the occasional debugging issue.
Within some URLs are frequently used (www.mydomain.com/HOME.ASP) and others contain &Parameters and stuff and are either relatively unique(www.mydomain.com/ViewBasket.ASP&BasketID=1234) or variable (www.mydomain.com/ViewProduct.ASP&ProductID=1234)
Currently I store the Referrer in a Child "Lookup" Table, and the PK ID in the "Logging" Table.
Some analysis of the data shows:
119,509 rows (pages logged [purged after a couple of days, only includes data where the Referrer is not blank!])
Of those there are 10,760 distinct Referrer values. An average of 11 Page Hits per Referrer value.
On the face of it that suggests that using a child table is good! However, for each row inserted into the Page Hit table I have to do the following to get the Referrer ID:
SELECT @MyReferrerID = ID FROM MyLookupTable WHERE MyValue = @MyReferrerValue IF @@ROWCOUNT = 0 INSERT ... @MyReferrerValue ... SELECT @MyReferrerID = @@IDENTITY
(MyLookupTable has a PK on [ID] and a Unique Index on [MyValue] )
(In a busy month we will add 100,000 rows to this Lookup table, in a slack month 20,000. These get "purged" after a while, so the table size stays about the same. The table is defragged [if required] daily and the Stats updated. There are 350,000 rows in MyLookupTable)
Obviously some values in MyLookupTable reoccur, others are unique - and get purged after a while. Inserting these new entries pushes MyLookupTable out of shape, the SHOW_STATISTICS start to look awful, an sp_recompile sorts it out (Why? The query plan doesn't change ... although obviously the "shape" of the table has, maybe the Stats got auto-updated, would that change anything?)
So I'm thinking about just storing @MyReferrer as a VARCHAR in the Logging table, and throwing away MyLookupTable.
So really I'm just looking at performance, not Normalisation ...
Hi I wanted to use the table variable in Stored proc , for that i have create the table variable in the main SP which will be used by again called sp(child SPs) now when i am trying to use the same table variable in the child SP, at the time of compliation it is showing error
Msg 1087, Level 15, State 2, Procedure fwd_price_cons, Line 149 Must declare the table variable "@tmp_get_imu_retn".
Can any body give me the idea how to complile the child SP with the same table variable used in the main SP.
There are two tables, parent and child table.Foreign key field of the child table is not a required field. If thedata is submitted w/o a value into the foreign key field, what shouldI make it as a default value? Should it be "null"?
Hi, This is probably straightforward but I'm not sure how to approach this problem.
I have 2 tables, one parent and a child. The child table has a Quantity and a Price field and also a FK to the parent table.
I want the parent table to display its own row data along with the Total Cost of the child rows in the child table. So it needs to multiply the price by the quantity but also do a sum of this calculated column.
To start off with I tried SUM( TOTALCOST ) and it didn't like it. I've got an idea I might need to create a View but was wondering what is the standard way of doing something like this? E.g.
I'm using SQL Server 2005 along side Visual Studio 2005, using VB to create a web application at work. Now I'd like to bunch together some child fields in a gridview when displayed. Have a look at the attached pic to show what I would like.
Is this possible via a query or would I need to set something up on the gridview to do this?
I'm playing with CTE and just want to expand my skills and ask how you would build this tree structure to fill that [Tree] column for table like in sample below:
/* CREATE TABLE #T1 (child_id INT, parent_id INT, tree VARCHAR(MAX))
