My dillema is this.
I have a table with the simplified sturcture like this:
Teacher
TeacherID
Name

YearlyTeacherRecord
TeacherID
Year
Phone Number
blah

I need a list of teachers with their most recent yearly teacher record. How would I do that
Hello all, I'm having a real hard time trying to figure this one out. I'm trying to create a sql query that selects both the parent name and it's children, but it's got to loop through all the record sets to populate a drop down as an end result.
I think I thought this out correctly:
I have 2 tables
category
relationship
tbl category
cat_id //auto int
cat_name // varchar
relationship
r_id // auto int
parent_id // int
child_id // int
both the parent_id and child_id are associated with the cat_id
in my category table I could have
1cars // this is parent
2 audi
3 bmw
4 chevy
Table data example
r_id parent_id child_id
****************************
1 1 15
2 1 16
3 1 17
4 2 55
5 2 56
etc...
I want to select both the parent cat_name from category and also select the child cat_name where the parent_id = #
I can do it manaully like this
select cat_name, cat_id, parent_id , child_id from category, relationships where child_id = cat_id and parent_id = 1
what is the best way to loop through all the parent ids to find child category?
Could this be done in a stored procedure?
thanks in advance.
Hi,I have a stored procedure that has to extract the child records forparticular parent records.The issue is that in some cases I do not want to extract all the childrecords only a certain number of them.Firstly I identify all the parent records that have the requird numberof child records and insert them into the result table.insert into t_AuditQualifiedNumberExtractDetails(BatchNumber,EntryRecordID,LN,AdditionalQualCritPassed)(select t1.BatchNumber,t1.EntryRecordID,t1.LN,t1.AdditionalQualCritPassedfrom(select BatchNumber,RecordType,EntryRecordID,LN,AdditionalQualCritPassedfrom t_AuditQualifiedNumberExtractDetails_Temp) as t1inner join(select BatchNumber,RecordType,EntryRecordID,Count(*) as AssignedNumbers,max(TotalNumbers) as TotalNumbersfrom t_AuditQualifiedNumberExtractDetails_Tempgroup by BatchNumber, RecordType, EntryRecordIDhaving count(*) = max(TotalNumbers)) as t2on t1.BatchNumber = t2.BatchNumberand t1.RecordType = t2.RecordTypeand t1.EntryRecordID = t2.EntryRecordID)then insert the remaining records into a temp table where the number ofrecords required does not equal the total number of child records, andthenloop through each record manipulating the ROWNUMBER to only selectthe number of child records needed.insert into @t_QualificationMismatchedAllocs([BatchNumber],[RecordType],[EntryRecordID],[AssignedNumbers],[TotalNumbers])(select BatchNumber,RecordType,EntryRecordID,Count(*) as AssignedNumbers,max(TotalNumbers) as TotalNumbersfrom t_AuditQualifiedNumberExtractDetails_Tempgroup by BatchNumber, RecordType, EntryRecordIDhaving count(*) <max(TotalNumbers))SELECT @QualificationMismatched_RowCnt = 1SELECT @MaxQualificationMismatched = (select count(*) from@t_QualificationMismatchedAllocs)while @QualificationMismatched_RowCnt <= @MaxQualificationMismatchedbegin--## Get Prize Draw to extract numbers forselect @RecordType = RecordType,@EntryRecordID = EntryRecordID,@AssignedNumbers = AssignedNumbers,@TotalNumbers = TotalNumbersfrom @t_QualificationMismatchedAllocswhere QualMismatchedAllocsRowNum = @QualificationMismatched_RowCntSET ROWCOUNT @TotalNumbersinsert into t_AuditQualifiedNumberExtractDetails(BatchNumber,EntryRecordID,LN,AdditionalQualCritPassed)(select BatchNumber,EntryRecordID,LN,AdditionalQualCritPassedfrom t_AuditQualifiedNumberExtractDetails_Tempwhere RecordType = @RecordTypeand EntryRecordID = @EntryRecordID)SET @QualificationMismatched_RowCnt =QualificationMismatched_RowCnt + 1SET ROWCOUNT 0endIs there a better methodology for doing this .....Is the use of a table variable here incorrect ?Should I be using a temporary table or indexed table if there are alarge number of parent records where the child records required doesnot match the total number of child records ?
View 2 Replies View RelatedDisplaying a list of parent and child objects in a certain way, here's the code to create and populate an example dataset.
CREATE TABLE OrgStructure

The dataset I'm working on contains ~700 rows and the OrgUnitNames can be anything, they aren't labelled like the example dataset with 1.1.1 and so on.
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:

insert @child select 1, 1, 'AA', '1/1/2015', '3/31/2015'

I was wondering if it is possible to use a generic list object to use as the datasource/data for a report? Right now we use these business objects to display information on our website and would be great it we could re-use those objects and create reports based on them. We are doing some calculations etc in the business layer to build these objects, so if we could re-use, that would be best.
Thanks!

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)
Looking for below output ...
Huh?
I've got good RI data...BUT..a developer loaded the tables in alpha table order....
Such that the child loaded BEFORE the parent....
Huh?
Got a test being set up now to mess with the child file to add a key that doesn't exist in the parent...
But Why is this allowed?
In DB2 you can specify
LOAD DATA REPLACE NO CHECK....
On the load card...you then need to run a check after to verify the data...
Is that what's going on? Is there such a utility in SQL Server to run a check post load?
I'm confused....
Any comments appreciated.

I have a parent/child relationship in a relational database broken out like this:
Table Name: categories[category_id] int (primary_key NOT NULL),[category_name] varchar(50),[parent_fk] int
The parent references the category_id in the same table to create the parent/child relationships. I can get all the bottom level categories by doing this:
select category_id, category, parent_fk from categories where category_id not in ( select parent_fk from categories)
Each bottom-level category has a count attached to it.
The problem I have is getting the counts rolled up for each parent of the bottom level. A parent could/will have multiple bottom-level categories (and counts).
My sql is a little weak, could you help me out? I can utilize everying in SQL 2000 (stored proc, UDF, anything).
Thanks!

I am designing a table to represent data in hierarchy structure, I use id and parent id to represent the data in hierarchy form:
Id | parent_id
---+-----------
1 | 0
2 | 0
3 | 0
4 | 1
5 | 1
6 | 4
7 | 4
8 | 7
9 | 7
This structure requires complicated queries (recursive call) to find out all the child of a root node, so I have added another field for the root id.
Is this a good relational database design ? kindly suggest.
Id | parent_id | root_id
---+-----------+---------
1 | 0 |
2 | 0 |
3 | 0 |
4 | 1 | 1
5 | 1 | 1
6 | 4 | 1

10 | 2 | 2
11 | 2 | 2
12 | 10 | 2
13 | 10 | 2

View 1 Replies View RelatedI am having problems creating a trigger in SQL Server? I have 2 tables (parent and child) with one to many relationship. When I save a record, one row gets inserted in the parent and one to many gets inserted in the child. The trigger is on the parent table and it is trying to select the number of new records just inserted in the child table that meets a certain criteria. Since the transaction hasn't been committed I can not select the number of records from the child. Does anyone know how to handle this? My manager insists this be done in a trigger.

Hello 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.
I am importing data from a paradox table and trying to clean it up. I have this query that finds all the child records that are not in the parent table.
Select MemberID
FROM memtype AS a
WHERE NOT EXISTS
(SELECT *
FROM members AS b
WHERE a.MemberID IN (b.MemberID));
Now I'm trying to delete all those child records instead of just selecting them so I tried...
Delete MemberID

(SELECT *

WHERE a.MemberID IN (b.MemberID));
Sql clearly doesn't like this

Hello,

Your Input would be greatly appricated.
hello there,
I think I might know the answer to this, but I wanted to see if any one has come up with a slick idea for enforcing this relationship. If I have two tables and one is dependent on the other (parent-child relationship), how can I enforce that every parent record has a corresponding child record? Here is a code example
USE tempdb
GO
CREATE TABLE dbo.Parent
(
ParentId int NOT NULL
)
ALTER TABLE dbo.Parent ADD CONSTRAINT PK_Parent PRIMARY KEY CLUSTERED (ParentId)
CREATE TABLE dbo.Child
(
ParentId int NOT NULL
,ChildId int NOT NULL
)
ALTER TABLE dbo.Child ADD CONSTRAINT PK_Child PRIMARY KEY CLUSTERED (ParentId, ChildId)
ALTER TABLE dbo.Child ADD CONSTRAINT FK_Child_Parent FOREIGN KEY (ParentId)
REFERENCES dbo.Parent(ParentId)
INSERT INTO dbo.Parent VALUES (1)
INSERT INTO dbo.Child VALUES (1,1)
INSERT INTO dbo.Parent VALUES (2)
INSERT INTO dbo.Child VALUES (2,2)
INSERT INTO dbo.Child VALUES (2,1)
INSERT INTO dbo.Parent VALUES (3)
SELECT
p.ParentId, 'I SHOULD HAVE A DEPENDENT RECORD'
FROM
dbo.Parent p
LEFT JOIN
dbo.Child c
ON
p.ParentId = c.ParentId
WHERE c.ParentId IS NULL
ParentId 3 should have a child record associated with it. I am assuming that these are my choices:
1) code all inserts to the parent table along with a insert to the child table and wrap those in a transaction
2) place a trigger for insert on the parent table that ensures that the child table is populated after data for the parent.
Here is the gotcha, we will be using a middle-tier data access layer (nhibernate or dlink) so .NET application developers will be creating the data modifications at the transactional level. Also there might be several ongoing ETLs that populate this schema as well, so multiple points of entry and seperate code blocks. I don't want to hide business logic within triggers.
I assume that all our coders are competent and could enforce this properly via code, but I know that mistakes happen. Has any one come across this situation and have a solution for enforcing the integrity of the schema with constraints?
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.

View 8 Replies View RelatedI have a fairly simple SSIS project that has nested parent-child packages.
I am trying to find the best way to manage the connections strings so as to make the package portable across machines and environments. Currently there is one "master" package which calls 6 child packages. 1 of these child package calls 3 child packages of its own.
For the database connections, I've settled on creating a standardized .dtsConfig file for each server/login. This is a relatively small number (intially 8) that I don't expect to grow much.
I've taken a different approach for the file-system connections used by Execute Package components that call the child packages. For each package that has child packages, I store all the connection strings (paths) to the child packages in a single .dtsConfig file. This works well for the top-level "master" package where I can pass in the .dtsConfig file (that has the paths to the child packages) as a run-time option in the Execute Package Utility.
However, this approach seems to fall apart for the 2nd generation package that in turn call 3rd generation packages because I don't know how to get the .dtsConfig file (with the 3rd generation .dtsx package paths) path to this downstream dtsx package.
Though I'm sure there are others, the only two solutionsI can think of now are
(a)don't nest packages beyond 1 parent/child relationship -- not really an option or
(b)Store the path of .dtsConfig files for each .dtsx package as an environment variable on each machine. This option is unappealing because it would require adding an environment variable for every .dtsx package that has child packages. I don't think it would take long for this to grow into a large number, that would make managing environment variables cumbersome.
So far my experience with SSIS has been that there was a simple solution for each scenario I had. So this hoop jumping I'm going through seems to indicate I am just missing something.
Is there a better way I am just not getting?
Hello,
I'm having problem to pass variable from a package to a another one.
I having 2 packages: the parent (parent.dtsx) use a Execute Package Task to execute the child package (child.dtsx).
In the parent package, I have a variable named var1 (data type String) with value=test
In my child package, I having a script task using the variable var1 to make a MsgBox (var1 is in readonly in the script):
MsgBox(CStr(Dts.Variables("var1").Value))
In this case, I having an error (cause the variable may no exist) but i can see the value of the variable in the MessageBox and the execute package task fail because of this error.
After I tried this solution: (Found in this Forum)
In the child package, I create the variable var1 (same type, no value). Then in the control flow, I right click on the background and select "package configurations".
I enable package configurations.
Then I add a new one. I change the configuration type to "parent package variable."
Then, in the specify configuration settings entry, I enter the name of the variable in the parent package.
On the following screen, I select the "value" property of the variable created in this package (Child package). At last, I give the configuration a name and hit finish.
If I execute my parent package, the result is no value in the MessageBox.
I also tried the same thing (with the package configuration) to pass a a variable with the connection string from a package to the connection of an another one (I set the connection string of the connection) and it doesn't work.
What did I miss ?
Thanks in advance for your help.

Hi there,
sorry if the message seems a bit garbled i cannot see the textbox properly with ie7/ff
anyways. the situation.
childpackage contains a loop-container. in there i use an ole-db-source with a variable
based on an expression. ie. "select * from foo where bar=" + len(@[bar]) == 0 ? "initial" : @[bar] + " and etc=1"
where bar is the variable that is set by the loop.
this works great.
however i need to call this package several times, only the expression is a tad different.
so i need a scripttask that sets the expression correctly, then i call the childpackage
and map the current-expression to the expression in childpackage.
how do i do that? or am i doing it wrong?
my script-task looks something like:
dts.Variable("theVar").Expression = " ""select * from foo where bar="" + len(@[bar]) == 0 ? ""initial"" : @[bar] + "" and etc=1"" "
in the childpackage i have a package-conf that maps thevar to thequery with target-object expression.
