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).

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.

Update Parent Table With Summation Of Its Child Records

May 24, 2013

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 am expecting the following after the update:

Code:
Select * from @t1

201200000018092013-03-14 00:00:00.000 211.15 10.00 3.14

All I am getting are the original values.

Transact SQL :: Use FOR XML To Return Multiple Child Records Within Each Parent Record

Aug 7, 2015

I have a single complex query.

SELECT 
Col1, -- Header, 
Col2, -- Header, 
Col3, -- Detail
Col4, -- Detail 
Col5, -- Detail
FROM 
TableName;

The query repeats the Header row value for all children associated with the header.I need the output of the query in XML format such that..For every Header element in the XML, all its children should come under that header element//I am using - 

SELECT 
Cols 
FROM 
Table Names 
FOR XML PATH ('Header'), root('root') , ELEMENTS XSINIL 

This still repeats the header for each detail (in the XML) , but I need all children for a header under it.I basically want my output in this format - 

<Header >
  <detail 1>
   </detail 1>
  <Detail 2>
  </Detail 2>
  <detail 3>
  </detail 3>
</Header>

Delete Child Records Without A Parent

Oct 12, 2013

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
FROM memtype AS a
WHERE NOT EXISTS
(SELECT *
FROM members AS b
WHERE a.MemberID IN (b.MemberID));

Sql clearly doesn't like this

Union Parent Child Records

Feb 24, 2014

I have an application that has an existing query which returns org units (parent and child) from organization table with orderby on createddate + orgid combination.

Also I added another log table Organization_log with exact columns as Organization table and additional 'IS_DELETED' bool column.

WITH Org_TREE AS (
SELECT *, null as 'IS_DELETED', convert (varchar(4000), convert(varchar(30),CREATED_DT,126) + Org_Id) theorderby
FROM Organization WHERE PARENT_Org_ID IS NULL and case_ID='43333'

[code]...

I need to modify the query:

1. To display the records both from the Organization table and Organization_Log table.
2. The orderby should be sorted on 'Organization Name' asc and it should follow the child order in alpha sort as well.

E.g.:

aaa
==>fff
==>ggg
bbb
==> aaa
==> hhh
eee
==> ccc
==> ddd
==> fff

Insert Parent Child Records...

Apr 28, 2006

Hello,

We have a complex functionality of migrating data from a single record into multiple parent child tables.

To give you an example, lets us assume that we have a single table src_orders in the source database. We have a parent Order table and a child OrderDetails table in the target database. We need to pick one row from src_orders and insert this row in the Order table, pick up its PK (which is an identity column) and then use this to insert rows (say 5) in the OrderDetails table.

Again, we go back to the source, take a row, insert it into Orders, pick up the Orders PK and insert n rows in OrderDetails.

As of now, we are using the following approach for achieving this functionality.

1. Get the identity generated from the target table and store both the source table id and the target table id in a recordset.

2. Use the recordset as the source to a foreachloop , using foreachADO enumerator

3. Use data flow tasks to get the fields from the parent table for the source id, that needs to be inserted into the target child table

In case I have not ended up confusing everyone, can anyone validate this or suggest a better approach? :)

Thanks,

Satya

Selecting TOP X Child Records For A Parent Record

Oct 29, 2006

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 ?

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

Writing Parent/Child Records To Flat File

Mar 19, 2007

I have a set of parent/child records that need to be exported to a space delimited Flat File. Each parent record must be followed by 3 child records, each on their own line with different format.

I have a prototype using the Derived Column component that concatinates the various fields of each record into one "wide" text column. This fools SSIS to think that each row has the same format. Then I merge them together using an artificial sort id. But this seems overly tedious and very brittle.

What would be the best approach to writing these records out? I'm hoping there is a better more maintainable method.

Thanks,

Jon

My Tables are in SQL 2005. I was thinking to read the Category records in a Data Reader and within the While Loop, call a SP to retrieve the matching records from Products Table. If matching records found, call System SP_Mail to send the E-mail. The drawback with that for every category records (Within While Loop) I need to call my SP to get Products Data. Will be OVERKILL? Ideally I would like extract my records with one call to a SP. Is there any way I can run a while loop inside the SP and extract Child Data based on Parent Record?  Any Help or sample URL, Tutorial Page will be appreciated.  Thanks

dbo.CorpAdv.pID is an integer and unique ID for each record, later records have higher numbers
dbo.CorpAdv.AcctNum is text field

How To Automatically Create New Records In A Foreign Table When Inserting Records In A Primary Table.

Sep 13, 2006

Ok, I'm really new at this, but I am looking for a way to automatically insert new records into tables.  I have one primary table with a primary key id that is automatically generated on insert and 3 other tables that have foreign keys pointing to the primary key.  Is there a way to automatically create new records in the foreign tables that will have the new id?  Would this be a job for a trigger, stored procedure?  I admit I haven't studied up on those yet--I am learning things as I need them. Thanks.

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

SQL Server 2014 :: Selecting Records From Table 2 While Counting Records In Table 1

Aug 11, 2015

Table1 contains fields Groupid, UserName,Category, Dimension

Table2 contains fields Group, Name,Category, Dimension (Group and Name are not in Table1)

So basically I need to read the records in Table1 using Groupid and each time there is a Groupid then select records from Table2 where Table2.Category in (Select Catergory from Table1)
and Table2.Dimension in (Select Dimension from Table1)

In Table1 There might be 10 Groupid records all of which are different.
