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).
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.
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
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]
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
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 -
declare @table table ( ParentID INT, ChildID INT, Value float ) INSERT INTO @table SELECT 1,1,1.2
[code]....
This case ParentID - Child 1 ,1 & 2,2 and 3,3 records are called as parent where as null , 1 is child whoose parent is 1 similarly null,2 records are child whoose parent is 2 , .....
Now my requirement is to display parent records with value ascending and display next child records to the corresponding parent and parent records are sorted ascending
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));
I have a parts table which has partid (GUID) column and parentpartId (GUID) column. Need to copy the records to the same table with new GUIDs for partids. How to do that? cursor or temp tables?
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.
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? :)
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 ?
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
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 for your time, How to calculate & save a Parent status [qcStatus varchar(30)] and Alert [alertFlag bit] in dbo.a1_qcParent based on comparison of its Child records in dbo.a3_qcItems2Fix columns [itemComplete bit] and [alertFlag bit] Where a1_qcParent[a1_id] = a3_qcItems2Fix[a1_ID]
- Parent CLOSED: if all children [itemComplete] are True - Parent OPEN: if any child [itemComplete] is False
- Parent ALERT: True if any child row [alertFlag bit] is True
Using sql_Datasource in webpage, but more comfortable in sql... After-Trigger? Can Parent columns have calculated formula referencing the child table? Please help.
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'

Folks,Using NorthWind as Example: Parent Table derived from: Categories. I added a new Column E-Mail and Selecting rows where Category Id <=3. Here is my Data.
Category ID Category Name Category E-mail
1 Beverages Beverages.com
2 Condiments Condiments.com
3 Confections Child Table derived from: Products. I am Selecting rows where Category Id <=3. Here is my Sample Data.
Category ID Product Name Quantity Per Unit
1 Chang 24 - 12 oz bottles
1 Côte de Blaye 12 - 75 cl bottles
1 Ipoh Coffee 16 - 500 g tins
1 Outback Lager 24 - 355 ml bottles
2 Aniseed Syrup 12 - 550 ml bottles
2 Chef Anton's Gumbo Mix 36 boxes
2 Louisiana Hot Spiced Okra 24 - 8 oz jars
2 Northwoods Cranberry Sauce 12 - 12 oz jars
3 Chocolade 10 pkgs.
3 Gumbär Gummibärchen 100 - 250 g bags
3 Maxilaku 24 - 50 g pkgs.
3 Scottish Longbreads 10 boxes x 8 pieces
3 Sir Rodney's Scones 24 pkgs. x 4 pieces
3 Tarte au sucre 48 piesI would like to read 1st Category Id, Category E-Mail from Categories Table (ie. Category Id = 1), find that in Products Table. If match, extract matching records for that Category from Both Tables (Categories.CategoryID, Products.ProductName, Products.QuantityPerUnit) and e-mail them based on E-Mail Address from Parent (Categories ) Table. If no E-Mail Address is listed, do not create output file. In this instance Category Id = 3.Basically I want to select 1st record from Parent Table (Here is Category) and search for all matching Products in Products Table. And Create an E-mail and sending just those matching records. Repeat the same process for remaining rows from Categories Table. I am expecting my E-Mail Output like this: For Category Id: 1
2 Northwoods Cranberry Sauce 12 - 12 oz jarsI am not extracting the Data for any user Interface (ie. Grid View/Form View Etc). I will just create a Command Button in an ASP.NET 2.0 form to extract Data. 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
I really need creating a query that will retreive all records from a table where the dbo.CorpAdv.AcctNum field equals a specific value (for this example "0023"), the TranCode = "R" and the sum of the records, starting with the latest, equals the value of a field in another table (dbo.Master.TotalAdv)
dbo.Master.TotalAdv is numeric (dollar amount) and in this example the value is $1,850.00
dbo.CorpAdv.pID is an integer and unique ID for each record, later records have higher numbers dbo.CorpAdv.AcctNum is text field dbo.CorpAdv.AdvAmt is numeric (dollar amounts)
I have a situation where I need a table if bad items to match to. Forexample, The main table may be as:Table Main:fd_Id INT IDENTITY (1, 1)fd_Type VARCHAR(100)Table Matcher:fd_SubType VARCHAR(20)Table Main might have a records like:1 | "This is some full amount of text"2 | "Here is half amount of text"3 | "Some more with a catch word"Table Matcher:"full""catch"I need to only get the records from the main table that do not haveanything in the match table. This should return only record 2.
I've 2 tables ResumeSkill (Child table) and Skill (Parent table), There are duplicates in the parent table and after removing the foreign key constraint in child table deleted all duplicate values from Parent table. But those deleted duplicate values has references in child table which need to be deleted now.
ResumeSkill Skill
Id SkillId SkillId Name
I want to delete all the records from ResumeSkill that dont have matching skillId in Skill table.
Can we push the data for the above query in a physical table and create index to make the query fast rather than using the same set tables multiple times
I need to delete records from a table (Table1) which has a foreign key column in a related table (Table2).
Table1 columns are: table1Id; Name. Table2 columns include Table2.table1Id which is the foreign key to Table1.
What is the syntax to delete records from Table1 using Table1.Name='some name' and remove any records in Table2 that have Table2.table1Id equal to Table1.table1Id?
I am developing an application in vb.net 2005 using SQL Server 2000. In this I have two tables SessionMaster and SessionChild. Fields of session master - SessionMastId, Start_Date, End_Date, Session_Type, Fields of session child - SessionChildId, SessionMastId, UserName, Comment. SessionMastId and SessionChildId are primary keys of respective tables and also they are auto increment fields. Please how to write trigger to insert record into both tables at a time.
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.
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?

What is sql for this delete?I appreciate your help. Please ignore table design and I just use it for myproblem illustration.Jim
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.
