Retrieve Values From Child Table

Feb 2, 2005

Hello there,





I need to get the last value (status) from a child table. I try to simplify the problem with the following example.





Create Table Users


(


UserId int,


Lastname nvarchar(50)


)





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.





Thx in advance.

Transact SQL :: Retrieve Currently Created Date From Master Table To Load Into Parent And Child Table

May 12, 2015

In Master tabel i have these date datas

2015-05-10

2015-05-11

2015-05-12

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.

Transact SQL :: Retrieve All Records From Parent Table And Any Records From Child Table

Oct 21, 2015

I am trying to write a query that will retrieve all students of a particular class and also any rows in HomeworkLogLine if they exist (but return null if there is no row). I thought this should be a relatively simple LEFT join but I've tried every possible combination of joins but it's not working.

SELECT
Student.StudentSurname + ', ' + Student.StudentForename AS Fullname,
HomeworkLogLine.HomeworkLogLineTimestamp,
HomeworkLog.HomeworkLogDescription,
ROW_NUMBER() OVER (PARTITION BY HomeworkLogLine.HomeworkLogLineStudentID ORDER BY

[Code] ...

It's only returning two rows (the students where they have a row in the HomeworkLogLine table).

What's The Accepted Way To Retrieve Records In A SQL Table With Null Values Using A Visual Studio 2005 Table Adapter?

Jan 21, 2008

I'm using an ObjectDataSource in Visual Studio to retrieve records from a SQL Server 2005 database.
 I have a very simple dilemma.  In a table I have fields FirstName, Surname, Address1, Address2, Address3 etc. None of these are mandatory fields.
It is quite common for the user not to enter data in Address2, Address3, so the values are <null> in the SQL table.
In Visual Studio 2005 I have an aspx form where users can pass search parameters to the ObjectDataSource and the results are returned according to the passed in parameters.
The WHERE clause in my Table Adapter is:WHERE (Address1 LIKE @Address1 + '%') AND (Address2 LIKE @Address2 + '%') AND   (Address3 LIKE @Address3 + '%') AND (FirstName LIKE @FirstName + '%') AND (Surname LIKE @Surname + '%')
If, for example, I simply want to search WHERE FirstName LIKE ‘R’, this does not return any results if the value of Address3 is <null>
My query is this: Could someone please show me the best way in Visual Studio 2005 to return records even if one of the Address fields is <null>.
For reference, I have tried: Address3 LIKE @Address3 + '%' OR IS NULLThis does work, however itsimply returns every instance where Address3 is <null>  (accounting for about 95% of the records in the database). Thanks in advance Simon

How To Postpone Trigger Fire Until After Both Parent And Child Table Values Have Been Inserted

Feb 13, 2008



Hi all,

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?

Thank you,
John

Retrieve A Recordset From One Table Based On The CSV Values In The Field Of Another

Feb 6, 2007

Hello!

I have 2 tables, one that contains a set of codes and their definitions, and another where each record has a field that contains several of these codes separated by commas:

Tab1

SubCode | Definition
---------------
S100 | Def of S100
S101 | Def of S101
S102 | Def of S102

Tab2

DepID | Purpcode |SubCodes
-----------------------------
1 | P100 | S100,S101,S102
1 | P101 | S100, S101
2 | P101 | S100,S102

I'm trying to create a query against Tab1 so that it retrieves a recordset of Subcodes and definitions based on the contents of the Subcodes field for a record in Tab2. I've tried this using a subquery, as follows:

SELECT SubCode ,Definition
FROM Tab1
WHERE SubjectCode IN
(SELECT CHAR(39) + REPLACE(SubjectCodes, CHAR(44), CHAR(39 + CHAR(44)+ CHAR(39)) + CHAR(39)
FROM Tab2
WHERE DepID = 1 AND PurposeCode = 'P101')

The subquery will return: 'S100','S101' and I expect the final recordset to be:

SubCode | Definition
---------------
S100 | Def of S100
S101 | Def of S101

However, it's not returning any records. If I execute the subquery separately and then plug its results into the main query e.g.

SELECT SubCode ,Definition
FROM Tab1
WHERE SubjectCode IN ('S100','S101')

it returns the expected recordset. Does anyone have any pointers? It's driving me nuts..

Cheers
Greg

Trying To Return A Single Record For Each Client From Child Table Based Upon A Field Of Date Type In Child Table

Nov 1, 2007

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..

Analysis :: Best Way To Add Additional Parent Child Attribute Values

Apr 16, 2015

I have a parent Child attribute in my dimension.  I am currently displaying the correct ID value as the business wants.  So now they can see the rollup of the ID(intOrgNodeID ) values.They would also like to see the same rollup of the Name (vcharOrgNodeName)  for this ID.However they do not want it concatenated.  They want to be able to see them separate.You cannot create two parent child attibutes in one dimension so not sure if there is some simple trick to make this work? It seems like there should be some simple trick for this. 

My dimension table looks something like this
intdimOrgNodeID int Key (surreget key)
intOrgNodeID int (Actual ID)
intDimParentOrgNodeID
vcharOrgNodeName
In the Propertys I have set this below.
KeyColumns  = tbldimOrgNode.intDimParentOrgNodeID
NameColumn = tbldimOrgNode.intOrgNodeID

Passing Multiple Values From Parent To Child Package

Dec 20, 2006

Starting with "How to: Use Values of Parent Variables in Child Packages" in the SQL Server 2005 Books Online (http://msdn2.microsoft.com/en-us/library/ms345179.aspx), it seems I need to create a separate package configuration in the child package (of type parent package variable) for each variable I want to pass from the parent to the child. Is that really so? The XML configuration file type allows me to specify any number of variables; how do I do that with the parent package variable?

For that matther, why doesn't the Execute Package Task simply allow me to specify the values of child variables (or other properties) directly? It seems SSIS has made something as trivial as a series of function calls completely opaque:

MyChildPackage(var1=1, var2="foo");

MyChildPackage(var1=2, var2="bar");

MyChildPackage(var1=3, var2="baz");

Retrieve When All Values In Group Have Same Record

Feb 25, 2015

Here is some sample data:

CREATE TABLE
#MyTable
(
Pk INT,
GroupID INT,
Value VARCHAR(10)

[code]...

I am looking to retrieve any GroupID in which every Value of that GroupID is either (a) null, (b) an empty string, or (c) "XYZ". So in the above example, GroupID #1 would not be returned in my query because there is a Value of "ABC", but GroupID #2 would be returned since it consists of only nulls, "XYZ"'s, and empty strings.What would be the most efficient way to write such a query?

Issue With Getting Values From Child Controls In A Gridview, To Use For The Update Using A SQLDataSource Control

Nov 21, 2006

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:
 
<asp:GridView ID="GridEditSettlement" runat="server" AutoGenerateColumns="False" BackColor="Navy"

<asp:SessionParameter DefaultValue="" Name="userid" SessionField="userid" />
</UpdateParameters>
</asp:SqlDataSource>
 
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

Retrieve NULL Values From Config File

Apr 10, 2008

Hi,

my configuration file provides parameters that are used for an SQL query in my package. However, for these parameters it must be possible to pass NULL to the query.

This seems to be impossible in SSIS..? If the config file provides no value, the package uses a default value - and this default value can not be null.

Any suggestions?

Thanks a lot,

Regards

Query Based Off Primary Key Of Parent Table - Adding Child Table

Jan 28, 2012

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)

Check Constraint - Compare Sum Of Two Values In One Table Against Values Located In Another Table

Jul 26, 2014

I am relatively new to SQL and as a project I have been asked to create the SQL for a simple database to record train details. I want to implement a check constraint which will prevent data from being inserted into a table if the weight of the train is more than the maximum towing weight of the locomotive. FOr instance, I need to add the unladen weight and maximum capacity of each wagon (located in the wagon type table) and compare it against the locomotive maximum pulling weight (the locomotive class table). I have the following SQL but it will not work:

check((select SUM(fwt.unladen_weight+fwt.maximum_payload) from
hauls as h,freight_wagon as fw,freight_wagon_type as fwt,train as t where
h.freight_wagon_serial_number = fw.freight_wagon_serial_number and
fw.freight_wagon_type = fwt.freight_wagon_type and
h.train_number = t.train_number) <
(select lc.maximum_towing_weight from locomotive_class as lc,locomotive as l,train as t where
lc.locomotive_class = l.locomotive_class and l.locomotive_serial_number = t.locomotive_serial_number))

The hauls table is where the constraint has been placed and is the intermediary table between train and freight wagon.

I may not have explained this very well; but in short, i need to compare the sum of two values in one table against a values located in another table...At present I keep getting a message telling me the sub query cannot return more than one row.

Transact SQL :: To Get Parent / Child / Grand Child Row On Various Order?

Jun 26, 2015

I have a table with below kind of data,

DECLARE @TBL TABLE (ItemId INT IDENTITY(1,1), ItemName NVARCHAR(20), ItemDate DATE, ParentItemName NVARCHAR(20), ItemOrder INT, ReportId INT)
INSERT INTO @TBL (ItemName, ItemDate, ParentItemName, ItemOrder, ReportId)
VALUES ('Plan', '2015-06-01', NULL, 1, 20),('Design', '2015-06-01', NULL, 2, 20),('Test', '2015-06-20', NULL, 3, 20),('Complete', '2015-06-30', NULL, 4, 20),
('Design child A', '2015-06-02', 'Design', 1, 20), ('Design child B', '2015-06-01', 'Design', 2, 20),
('Test child A', '2015-06-10', 'Test', 1, 20), ('Test child B', '2015-06-09', 'Test', 2, 20), ('Test child C', '2015-06-08', 'Test', 3, 20),
('Test grand child A', '2015-06-08', 'Test child B', 1, 20), ('Test grand child B', '2015-06-08', 'Test child B', 2, 20)
select * from @TBL

Here I want,

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)

Looking for below output ...

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 .

Thinks to help me

T-SQL (SS2K8) :: Stored Procedure To Truncate And Insert Values In Table 1 And Update And Insert Values In Table 2

Apr 30, 2015

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.
