I have a table called "College". In a table, I have to create a structure for multilevel parent-child relationship
For Example,
1) State has number of colleges, Number of colleges has Number of dept. , Number of dept. has no. of subjects, no. of subject has number of chapters and the hierarchy goes on.
Expected Output is,
College 1
Dept 1
subject 1
subject 2
subject 3
Dept 2
Dept 3

I tried in so many ways, I do not know how to query in single table.
I want to build Parent child relation . i have two aproaches .I would like to know which is the best solution ?
1)1st method:-
Parent table with parent id . Child table with child id and parent id.Foreign key relationship exists between parent and child tables with cascade delete option enabled.
Parent TAble
Id name
1 XYZ
Child table
id name parent id
1 abc 1
2 qwe 1
2)2nd method
table with id and parent ID. Top level element will have null value in table. eg
id name parent id
1 xyz
2 abc 1
3 qwe 2
4 adf 1

Which is the best solution to store parent child relationship???
i have 2 Tables. i am saying emails in table1 and also if there is any attachments there i saved them also in the same table but with differet ID, and in another table i am saving the relationship of both documents.
Now i have defined another table in which i want to store a single New ID generated by the new Table to email document and it's attachment document..
what i am now doing i just create a SP, and it's take the first record from the main table and check if there is attachments , if no then it's just assign a new ID and save the document id into newly created table, but if there is attachement then it's go to relationship table and returen me the child id on behalf of parent ID and then in the newly created table it save the child docment id with the same id as the parent id has already been saved.
i m doing like this
SELECT all the emails those has attachments..
Insert Into newlyCreated Table (ID,doc)values(1,1)
then SELECT doc from Relationship table where Maintable doc=@doc
Insert into newlycreated tAble(ID,doc)values(1,2)
and so on .. and if i have more then one attachement then i have to use the loop..
what i m looking , is there any short way to do this all, bcoz it's taks ages to do.. is there any single line query that i can use to get the child doc id rather then going into loops ..
I want to retrive the output in a single SQL query.
I had two columns in a table; I used some values of column1 in column2. I want to identify all the column1 vlaues in Left Hand side and column2 values in Right Hand side, with a single query.
example:
MasterTable
ParentRow ChildRow --------- -------- A B C D E F G C H E M G
Output required:
ParentRow ChildRow --------- -------- A B C D E F G D (C mapped tfrom D) H F M D (G mapped from C, and C mapped from D)
To get the above output, I written query using WHILE...[BREAK|CONTINUE] concept until I get @@rowcount become zero.
I am looking for better performace and to get the output in a single query, instead of multiple passes.
Can any one suggest good tools and articles on performance tuning techniques?
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'
I've 2 tables QuestionAnswers and ConditionalQuestions and fetching data from them using CTE join and I'm seeing repetitive rows (not duplicate) like, If you have multiple answers for 1 question, the output is like
where london where paris where toronto
why us why japan why indonesia
I want to eliminate the repetitive question and group them as parent child items.
with cte as ( select cq.ConditionalQuestionID from ConditionalQuestions cq inner join QuestionAnswers qa on cq.QuestionID=qa.QuestionID where cq.QuestionID=5 and qa.IsConditional='Y') select distinct q.Question, a.Answer from QuestionAnswers qa inner join Answers a on a.AnswerID = qa.AnswerID inner join Questions q on q.QuestionID = qa.QuestionID inner join cte c on c.ConditionalQuestionID = qa.QuestionID;
Include children and exclude children in a single hierarchy in parent child dimension in mdx

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..
Below is my sample data of my table named "Groups"
Code: with Groups as ( select 1 as GroupId,'Oracle' as GroupName,0 as IdParentGroup union all select 2 as GroupId,'Microsoft' as GroupName,0 as IdParentGroup union all 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.
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.
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.

if i give categoryid=5[Note:Tyson] result should be as 1 boxing [main category] 5 tyson [sub category]
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.
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.
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'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))
insert into Hier select 'subramanium','Manickam' union all select 'subramanium','Munuswamy' union all select 'Munuswamy','senthil' union all select 'Munuswamy','sasi' union all select 'Munuswamy','uma' union all select 'manickam','vijay' union all select 'manickam','bhavani' union all select 'manickam','dhanam' union all select 'uma','varsha'
Delete from Hier where child='uma'
I tried:
select parent from Hier where parent not in(select Child from Hier) and parent <> 'subramanium' Getting resultset as: parent ====== uma
I need to know whether my select statement is correct or not,if its correct,how to write the same in CTE?
I have two table both say A and B.If i insert a record in A that record should be inserted in B.If i delete a record in A that record should be deleted from B.Is that possible.If yes please tell me.Thankyou in advance,vishnu
Hi, I have tables parent - PurchaseInvoices and child - PurchaseInvoiceDetails. I have trigger in PurchaseInvoiceDetails that would update stock qty based on Location code stored in parent table - PurchaseInvoices upon INSERT/UPDATE/DELETE.
I also set table RI to have cascade delete. I faced problem that, when I delete record in parent table, it would cascade delete child table. Trigger in child table fired and try to update stock qty. However, in this case, trigger unable to locate parent table record anymore.
How to overcome this? I can't move my stock update code to other place since I got to update stock if any changes happen to child table.

We have equipment table which stores Equipment_ID,Code,Parent_Id etc..for each Equipment_ID there is a Parent_Id. The PK is Equipment_ID Now i want to select the Code for the Parent_Id which also sits in the same table. All the Parent_Id's also are Equipment_ID's.
I am sure someone must have run into this before. I have a couple of tables with a parent child relationship.
I created a trigger on the insert of the parent but don't want it to fire until both the parent and child have been inserted into.
However sometimes the child may not get inserted in to at all. In other words it is a 1 to 0 or more relationship.
I created the whole insert into the parent and the child and wrapped it all up in a transaction hoping that the trigger would not fire until the transaction actually completed.
However such is not the case and it fires when the parent is inserted into but nothing is inserted into the child yet even though that is part of the transaction.
Is it possible to postpone trigger fire until after both parent and child table values have been inserted?
1. to display all parent with ORDER BY ItemOrder (no need to sort by ItemDate) 2. display all child row right after their parent (ORDER BY ItemOrder if ItemDate are same, else ORDER BY ItemDate) 3. display all grand child row right after their parent (ORDER BY ItemOrder if ItemDate are same, else ORDER BY ItemDate)
I am working on SQL server 2005 Reports. I have one report, one dataset is assigned to it, and one table which displays it. Now I come accros requirement that, the column value in the filter condition for the table is present in one textbox.
I can not use textbox i.e. reportItems in filter condition. Can someone suggest me how to use textbox value in filters?
I want to display parent/child records on report. I am not getting the proper solution.
The data is like this:
Sequence ItemCode IsParent
1 XYZ 0 'do not have child record
2 PQR 1 'have child records with sequence no 3
3 ASD 0
3 AFDGE 0
3 VDC 0
4 ASR 1 'have child records with sequence no 5 5 ASR 0
If IsParent = 1, that record has child records with sequence = parent sequenece + 1
I think u can understand the data I need to bind, and it is like:
XYZ
+ PQR
ASD
AFDGE
VDC
ASR
On + click we can do show/hide of child records.
I m not getting how to achive this in SQL server report. Can u give some hint?
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
