Transact SQL :: Select Records From Two Child Tables
Jun 18, 2015
i have 3 tables names parent, child1, child2 parent has 1 record, child1 has 2 record and child 3 has 3 records the script
select Parent.*,child1.f1,child2.f2 from child1 inner join Parent on parent.id =child1.id
inner join child2 on child1.id =child2.id
running above query gives me sixes rows but i want only all rows of childs but not their Cartesian products
Object: Table [dbo].[Parent] Script Date: 06/18/2015 17:33:02 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE TABLE [dbo].[Parent](
[id] [int] NOT NULL,
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 been able to get this select query to work, but I'm not sure how to modify it to turn it into a DELETE query:
USE QSCTestENG select p.[testid], COUNT(c.[testid]) FROM [dbo].[tblTestHeader] p left outer join [dbo].[tblTestMeasurements] c ON p.[testid]=c.[testid] where p.[model] = 'XPPowerCLC125US12' group by p.[testid] having COUNT(c.[testid]) <>48;
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 -
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).
I have used Aasim Abdullah's (below link) stored procedure for dynamically generate code for deletion of child tables based on parent with certain filter condition. But I am getting a output which is not proper (Query 1). I would like to have output mentioned in Query 2.
Link: [URL]
--[Patient] is the Parent table, [Case] is child table and [ChartInstanceCase] is grand child
--When I am deleting a grand child table, it should be linked to child table first followed by Parent
--- Query 1
DELETE Top(100000) FROM [dbo].[ChartInstanceCase] FROM [dbo].[Patient] INNER JOIN [dbo].[Case] ON [Patient].[PatientID] = [Case].[PatientID] INNER JOIN [dbo].[ChartInstanceCase] ON [Case].[CaseID] = [ChartInstanceCase].[CaseId] WHERE [Patient].PracticeID = '55';
--Query 2
DELETE Top(100000) [dbo].[ChartInstanceCase] FROM [dbo].[ChartInstanceCase] INNER JOIN [dbo].[Case] ON [ChartInstanceCase].[CaseId]=[Case].[CaseID] INNER JOIN [dbo].[Patient] ON [Patient].[PatientID] = [Case].[PatientID] WHERE [Patient].PracticeID = '55';
how to modify the SP 'dbo.uspCascadeDelete' to get the output as Query 2
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 need to compare records between two tables. There is no ID in the tables to do a simple join between them. So, what I'm looking for is: get the first record from table1 and read all record from table2 and give me back the most similar record. The String Distance is a predefined function.
Select a.table1 ,b.table2 from table1 a, table2 b where StringDistance (''a.table1,'b.table2') >90
Lets say we are executing this query below to retrieve each customer and the amount associated to a table
"INSERT INTO tblReceiptDue (Dealer, Amount) SELECT CustomerName, SUM(CASE WHEN VoucherType = 'Sales' then Outbound ELSE - Inbound END) AS AMOUNT from tblSaleStatementCustomer WHERE CustomerType = 'Dealer' GROUP BY CustomerName"
Table 3: ID RoleID Time 1 1 09:14 2 1 09:15 1 2 09:16
Now I want all the records which belongs to RoleID 1 but if same ID is belongs to RoleID 2 than i don't want that ID.From above tables ID 1 belongs to RoleID 1 and 2 so i don't want ID 1.
I have customers named Alex (Cid=1), Bob (Cid=2), and Carrie (Cid=3) in a table customer.
Cid First_Name 1 Alex 2 Bob 3 Carrie
I have products name Gin (Pid=1), Scotch (Pid=2) and Vodka (Pid=3) in a table products.
Pid Product_Name 1 Gin 2 Scotch 3 Vodka
And I have a table that holds purchase called Customer_Purchases that contain the following records:
Cid Pid 1 1 1 2 2 1 2 3 3 2
I would like to make a marketing list for all customers that purchased Gin or Scotch but exclude customers that purchased Vodka. The result I am looking for would return only 2 records: Cid’s 1 (Alex) and 3 (Carrie) but not 2 (because Bob bought Vodka).
I know how to make a SELECT DISTINCT statement but as soon as I include Pid=2 This clearly doesn’t work :
SELECT DISTINCT Pid, Cid FROM Customer_Purchases WHERE (Cid = 1) OR (Cid = 3) OR (Cid <> 2)
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
HiI'm using Access 2002. I have 2 tables tblGroupContact,tblGroupPermission, both have 2 fields identical structure:ContactID GroupID (Both are Composite keys and both hold integers)tblGroupContact holds everybody and the groups they are members of.tblGroupPermission holds only those people who have permission to makechanges to another part of the DB.The SQL at the end of post works, but opens a dialogue box looking fora parameter value 'query1.ContactID'Clicking enter or cancel (without entering anything) works OK.What have I done wrong to cause this parameter request.Thanks ColinKSELECT tblGroupContact.ContactID, tblGroupContact.GroupIDFROM tblGroupContact LEFT JOIN tblGroupPermission ON(tblGroupContact.ContactID = tblGroupPermission.ContactID) AND(tblGroupContact.GroupID = tblGroupPermission.GroupID)WHERE (((tblGroupPermission.ContactI*D) Is Null) AND((tblGroupPermission.GroupID) Is Null));
I want to select all of the date and weekDay values from tblWagesWeeks for a specific weekID. I also want to show all entries fromtblTimeEntry for the weekID when a record exists. If data does not exist in fromtblTimeEntry I want to display a blank entry but still need weekDay and date from tblWagesWeeks.
I'm trying to look for an efficient way to select records from two tables, combine them (not just one set above the other) and also efficiently page the results as well as dynamically order by specific columns. So far I have this....
INSERT INTO @Temp SELECT i.ID, i.Name, Type = 'I' FROM Item i UNION SELECT p.ID, p.Name, Type = 'P'FROM Package p
SELECT * FROM @Temp ORDER BY Name ASC
I was going to then implement some sort of of ROW_NUMBER like paging and ordering on the @Temp table variable. Problem is there could be potentially 1000's or more Items and Packages and they would all go in this single Temp table before having records 1 to 10 returned. Is there a more efficient way of doing this before I proceed any further?
I encontered a problem which did not allow me to select any thing from the temparary tables of the tempdb database. (e.g one of the temparary tables is #239E4DCF), why is that and how can we solve this problem? As I urgently need to look at this tempdb database, it is full. I am looking forward to hearing from you and thanks a lot in advance for your help.
I have table1 which has many unique ID numbers and table2 that has many records for each ID. some of the ID numbers in table1 have changed and I have created a translation table (table3) that links the old and new ID numbers.
What I need to do is some sort of update sql statement that updates all the records in table2 changing all the oldID numbers to the new ones using the translation table.
Table1 and table2 are not linked...can anyone help me with the sql statement
example
Table 1 IDNUM NAME 12345 Joe 12346 Mary 12347 David
I need to insert a record in a master table and 20 records in a child table. I want to do this using stored procedure. Is it better to do it in stored procedure? Have somebody already tried this? Or is there any sample that I can use?
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.
I have been involved in a project wherein i have to delete old records from two table and the corresponding child records from the interlinked tables. I try to find a SQL Procedure that deletes the child records, but that procedure uses the sysforeignkeys table for recursively deleting the child records. When i looked at my sysoreignkeys table, it was empty(no rows). Request you all if you can provide me the SQL Procedure that can delete record in the table with the child records.
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]
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? :)
1. For U_ID = 1, we have two diffrent U_NM and for one U_NM we have 2 child data. Need to show parent data order by U_ORD and need to show child data within their parent order by U_DT
2. For U_ID = 2, we don't have child data, hence need to show data order by U_ORD only
SELECT 1 AS U_ID, 'Plan' AS U_NM, '06/01/2015' AS U_DT, 1 AS U_ORD, NULL AS P_U_NM UNION ALL SELECT 1, 'Cust Plan 2', '06/05/2015', 0, 'Plan' UNION ALL SELECT 1, 'Cust Plan 1', '06/10/2015', 0, 'Plan' UNION ALL SELECT 1, 'Design', '06/15/2015', 2, NULL UNION ALL SELECT 2, 'Plan', '06/20/2015', 1, NULL UNION ALL SELECT 2, 'Design', '06/25/2015', 2, NULL
The problem of mine is, I have a datagrid, Which displays data from a Employee(parent) table. Now I want to delete some records based on the user selected checkbox,only those records which has no related records in the EmployeeProject(child) can be deleted.I want to know which are all the record that cannot be deleted? How can I achieve this?
tblServer represents a server, tblInstance represents any SQL Server instances present on the server. They're related thru srvID.
I'd like to write a query that gives me servers with all instances, on one row. This dataset will populate a List in an SSRS report.
I have this but it's clunky and does not provide for more than 2 instances on the server. I'd like this to account for any number of instances all on one row without having to hard code multiple joins:
with serverInfo as ( select srv.srvType as Type ,srv.srvName as ServerName ,srv.srvIP as ServerIP ,ins.instNetName as InstanceNetName
