Transact SQL :: Retrieve Descendants With Depth Level
Nov 22, 2015
I have a table of Affiliates, each Affiliate can have a ParentId, which refers to another Affiliate. How can I retrieve all children of a given Affiliate, along with their depth level? I have this query which selects the total number of descendants of a given Affiliate, but I need to select all the children + their depth level, up to a certain level.
WITH Descendants AS(
SELECT RootId = Id, Id
FROM Affiliates
UNION ALL
SELECT RootId, Af.Id
FROM Descendants
[Code] .........
What I want to achieve is a statement that has 3 parameters: RefererId, StartLevel, and EndLevel.
I need a statement that selects all the specified Affiliate.ReferrerId's descendants including their level distance from the referrer, filtered by the StartLevel and EndLevel (WHERE CurrentLevel >= StartLevel AND CurrentLevel <= EndLevel ).
I've got a fairly large hierarchy table and I'm trying to put together a query to find the lowest level descendants of the hierarchy. I think there must be some way to use the "Breadth-first" approach that's stated in the MSDN technet sites about SQL Server HierarchyID but i'm not sure how to write the necessary T-SQL to traverse that. I know I can get all the descendants of a parent node like this
SELECT * FROM AdventureWorks2012.HumanResources.Employee WHERE OrganizationNode.IsDescendantOf(@ParentNode) = 1
However, this query returns all levels for that parent's branch. If I just wanted list of employees that were at the lowest level of the branch(es) for this parent node, how would I do this?
has anyone out there found a way to get the best of both recursive hierarchy and drill down in the same report, ie without needing to know how many levels there are in your hierarchy, still being able to report them like a tree view with collapse and expand capability at each level?
I have a report which is grouped by a field called R_ID, which gives me a list of records for each R_ID. So here is the thing, I want to get only top 3 records for each R_ID. Is there any way to do this thing in the report level. I tried it from the query level, but the result is not like what I wanted.
I want to reach and display the value of @data inside if [wwtest].
The UDT is from the database [test] and I retrieve an error message "The type name 'test.dbo.tvf_id' contains more than the maximum number of prefixes. The maximum is 1.".
I don't know how to retrieve the data from the database test inside of the query document for [wwtest]?
create table datatable (id int, name varchar(100), email varchar(10), phone varchar(10), cellphone varchar(10), none varchar(10) );
Hi there, I'm new here and quite green when it comes to SQL in general - I havent used it in any depth for some years and, in the absence of our DBA I've been asked to produce a report... I'm just using query analyser to extract some data as I don't have access to Crystal or anything similar...
I have a table laid out as follows - the PK is REC_ID. It basically stores all the contract start dates for each client we deal with.
I can easily extract, for example, how many companies have taken up individual services, or many times individual services have been employed... what I'm having difficulty with is trying to extract, for example, all those companies who have had say taken up ICT AND SOFT services, whether explicit or using a LIKE statement.
For instance, if I wanted to find all those companies that had taken up both 'ICT-Hardware' AND 'Soft-Maintenance' and literally just get back the results...
Company
ABCLtd SteetsPLC
Or a numeric result(in this case 2) would be ok...
How would I do that?
Sorry, this may seem to be very obvious to you but I'm at a loss...
I want to enforce a constraint on the table where , the same MenuId cannot have 2 different prices for the same date range (accidentally).I think CHECK constraint won't work.
We are accessing a database through Linked Servers. That database has a bunch of views.We are able to get a list of columns for our views by querying [syscolumns]. However, how do we find out which of those columns have primary keys?
DECLARE @PN_INC INT, @POSITION_DESC VARCHAR(15) SELECT @PN_INC= MAX(PositionNumberInc) FROM dbo.tblPosition WHERE LTRIM(RTRIM(UPPER(PositionDescription)))=LTRIM(RTRIM(UPPER(@POSITION_DESC))); SELECT @PN_INC is returning null when there is no record in the table;
1. how can I make it return 0 when @PN_INC is null else it should pick the MAX(PositionNumberInc) value
2. I have written the below query to return 0 when @PN_INC is null but I need query to select the MAX(PositionNumberInc) value when @PN_INC is not null
SELECT @PN_INC= coalesce(MAX(PositionNumberInc), 0) FROM dbo.tblPosition WHERE LTRIM(RTRIM(UPPER(PositionDescription)))=LTRIM(RTRIM(UPPER(@POSITION_DESC)));
I have a database table where upon inserting a new record, I get 1 row(s) affected twice. But when deleting the record, I only get one instance of that message. I'm not really an expert, neither have I designed the database, but how can I retrieve the actual affected rows or determine what table does the other row pertain to?
We have one table.We have updated the status for one column to 1 and we did not committed the transaction. Can we do an another update on another row.
In below example i am updating GEO_D and transaction is not committed. Now my requirement is we have to update other records (not Geo_D). If try to update GEo_D it should wait.
IF OBJECT_ID('TEMPDB..##TEMP_STSTUS') IS NOT NULL DROP TABLE ##TEMP_STSTUS CREATE TABLE ##TEMP_STSTUS ( ID INT IDENTITY(1,1) ,NAME VARCHAR(10) ,STSTUS VARCHAR(10) ) INSERT INTO ##TEMP_STSTUS SELECT 'GEO_D','0'
I have a table (can't change the schema of it since it is part of an off the shelf app ) that has columns for individuals which I need to extract several pieces of information, essentially Phone, Email Address, etc. See U1 - U6
What is a better way to return this information rather than multiple joins?
My 3D bar charts don't look as good as they could because the bars are too thick when displayed in 3D (depth-wise). If I have many bars, the bars are very thin on the front, and then go back far too much. Has anyone played with the settings to see how to optimize this? Even with 5% rotations, it is still too thick for my taste and doesn't look like the previews in the designer.
I have a query which works absolutely fine when connecting to an actual server:
WITH CLAIMDATA AS( SELECT DISTINCT DB_NAME() AS DBName, 'UA' AS Client, POLICY AS KMPONO,
[code]...
If i change the connector to REPLPROD (which is a linked server): From REPLPROD.XUNMDTAUAI.dbo.UPPOREP UP INNER JOIN REPLPROD.XUNMDTAUAI.dbo.UKKMREP UK
I get the error:
Msg 8180, Level 16, State 1, Line 1 Statement(s) could not be prepared. Msg 125, Level 15, State 4, Line 1
I am trying to pick up the customers invoiced twice or more within a month. In the case below Pepsi Cola and Jack Daniel were invoiced twice in October. The query need to pickup the previous month, se being in October I need to pick up the invoice of September.
In my query, I am showing Student Record and also want to retrieve the last class attended by the student using JOIN to the table (ClassHistory).
Master ID Student_Name 1 Arindam 2 Brenda 3 Callie
(ClassHistory) ID Class Year 1 4 2003 1 5 2004 1 6 2005 2 4 2003 2 5 2004 3 4 2003
DESIRED RESULTSET ID Student_Name Class Record 1 Arindam 6 2 Brenda 5 3 Callie 4
The result is like - Arindam last class was Class 6, while Brenda was in Class 5 and Callie was in class 4.
Please note that the query will b part of a larger query and the Class record to be retrieved from ClassHistory if possible need to be retrieved through JOIN.
I need to group by transactions at line item level. As the each item in the transaction may belong to different category and I'musing case statement to identify particular category for one column , I'm using sub-query to retrieve the results at item level.
Below is the query in which i want to retrieve another column (exchange rate) from a particular date for the sub query.
Actually PurchaseOrderDet table get records related to purchaseorder but for each row in purchaseorderdet need info from the same table for all rows on a particular date.
how i can achieve this query without using RANK() and other functions.
"SELECT Supplier.Uniid AS SupplierID, Supplier.Name, PurchaseOrder.Uniid AS PurchaseID, PurchaseOrder.OrderNo, PurchaseOrder.FormDate, StockItem.Uniid AS StockID, StockItem.StockCode + N' - ' + StockItem.Description1 AS StockItem, PurchaseOrderDet.ExchangeRate, PurchaseOrderDet.UnitPrice, PurchaseOrderDet.Discount, SUM(PurchaseOrderDet.OrderQty) AS SumOfOrderQty,
We have a service that inserts some rows into a parent table (P) and child table (C). This operation is atomic and performed within a transaction.
We also have a service that queries these tables such that rows are (should only be) returned from P where there are no children for that parent.
The SQL that performs this is simplified below:
SELECT P.SomeCol FROM P LEFT OUTER JOIN C ON P.PKofP_Value = C.PkofP_Value WHERE C.PkofPValue IS NULL AND P.SomeOtherCol=0
Our expectation is that the query service should only return rows from P where there are no rows in C.
However, this seems not to be the case, and occasionally we find that rows from P are returned where there are matching rows in C.
We are sure that the process that inserts rows into P and C does so within a single transaction.
We have traced this with SQLTrace and can see the txn stag and committing and all operations using the same transactionid within the transaction.
We are running the default isolation level committed.
In SQLTrace we can see the query process start, the inserter process start and complete and then the query process continue (after presumably being blocked).
So how can the query process "miss" the child rows and return the parent from the above query?
Is it possible that, in this isolation level, the inserter process can block the query process such that when the inserter process commits and when the query process continues it does not see the child rows inserted because they were inserted in the table/index "behind" where the query process has already read - some kind of phantom phenomenon?
Goal: My request is the retrieve the return result from sp_Test as 8, 2, 4, 1 ,3 (take a look at picture 1) based on the chronological list from User-Defined Table Type dbo.tvf_id.
Problem: When I execute the stored procedure I sp_Test I retrive the list that is from 1 to 8. I don't know how to do it?
Information: I'm using SQL server 2012
create table datatable (id int, name varchar(100), email varchar(10), phone varchar(10), cellphone varchar(10), none varchar(10) ); insert into datatable values
I work for an organization that repairs serialized devices. Each time a device is repaired it's serial number is recorded in a database table along with the date it was repaired along with other information about the device. There are multiple cases where a unit has been repaired more than once.
I am trying to write a query that will return the serial only once and that record will be the record of the latest repair date. To sum it up,
Return a list of serials where if a serial exists more than once in the table, return only the instance of the serial record(s) with the max(created_dt). The end result will be a list of distinct serial numbers.
Here is my Query. The problem I believe is in my sub-query but I am not sure how to structure it.
Since installing Reporting Services on my machine, I have been getting an error whenever I try to execute a reader.read line.
When I ran the same exact code on another machine using someone else's credentials who did not have Reporting Services it ran fine. When I tried to run it on someone else's machine who did not have Reporting Services using my own credentials, I got the same error. Also, when the person who's pc and credentials worked fine on his machine ran the same code back on my machine using his own credentials, he got the same error. When another person who also had Reporting Services tried to run it on his own pc, he got the error as well.
When the reader is first executed (MyDataReader = sSql.ExecuteReader) these were the property values: depth = 0 fieldcount = 5 hasrows = true isclosed = false Item = In order to evaluate an indexed property, the property must be qualified and the arguments must be explicitly supplied by the user. recordsaffected = -1 (even though there are records) VisibleFieldCount = 5
When the reader is loaded into a table (MyTable.Load(MyDataReader)) then the property values changed to:
Depth = {"Invalid attempt to Depth when reader is closed."} FieldCount = {"Invalid attempt to Depth when reader is closed."} HasRows = {"Invalid attempt to Depth when reader is closed."} IsClosed= True Item = In order to evaluate an indexed property, the property must be qualified and the arguments must be explicitly supplied by the user. RecordsAffect = -1 VisibleFieldCount = {"Invalid attempt to Depth when reader is closed."}
And when I execute the the following code:
dtReader = MyTable.CreateDataReader()
While (dtReader.Read()) I get this error: "DataTableReader is Invalid for Current DataTable"
Since the code works with someone else's credentials on a machine that does not have SSRS, and the same problem happens for me regardless of what machine I am on as long as I am using my own credentials what could be causing my problem?
I have an SSIS Package which Retreives Data using a SQL Query like below
select a.* from dbo.test a (nolock) JOIN dbo.test1 b (nolock) ON a.DetailsId = b.DetailsId JOIN dbo.test c (nolock) on c.DetailsLineId = b.DetailsLineId where convert(date,c.CpPlacedDate)>? and convert(date,c.CpPlacedDate) < convert(date,GETDATE()) and c.PartnerCode in ('akakak07')
The CpPlacedDate DataType is Datetime. After the Successfull Execution of SSIS Package the final output results in destination is lesser than source.
The Maximum of cpplaceddate in the Destination for a particular date is '2015-06-13 23:46:08.923'
The Maximum of cpplaceddate in the Source for a particular date is '2015-06-13 23:59:14.873'
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.
I want to perform column level and database level encryption/decryption.... Does any body have that code written in C# or VB.NET for AES-128, AES-192, AES-256 algorithms... I have got code for single string... but i want to encrypt/decrypt columns and sometimes the whole database... Can anybody help me out... If you have Store procedure in SQL for the same then also it ll do... Thanks in advance
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).
When you utilize transactions in ADO.NET are the locks put on the entire TABLE used or at the row level? For instance if you do a SELECT within a transaction if you only pull 5 rows out of a 1000 row table can you just make it lock the rows that have been pulled? It seems like it locks the entire table?
