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?

Hi all,
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.
Please let me know if some body has any idea.
Thx.

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),

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.
RECID------Company-----Product-----------Date
445as------ABCLtd------ICT-Hardware------2007-01-14 00:00:00.000
253s1------ABCLtd------SOFT-Mainstream---2007-01-18 00:00:00.000
567o8------ABCLtd------SOFT-Maintenance--2007-01-18 00:00:00.000
809b9------Gen4Ltd-----ICT-Hardware------2007-01-14 00:00:00.000
098xc------Gen4Ltd-----SOFT-Maintenance--2007-01-18 00:00:00.000
551df------SteetsPLC---ICT-Hardware------2007-01-14 00:00:00.000
919sd------SteetsPLC---SOFT-Upgrade------2007-01-18 00:00:00.000
010qr------SteetsPLC---SOFT-Maintenance--2007-01-18 00:00:00.000
124vv------SteetsPLC---PERS-Allocations--2007-01-18 00:00:00.000
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...
Hope you can help.

The below is my query in SQL SERVER 2012
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?

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?
Select
[AccountNumber]
,a.[AccountId]
,[Name]
,[new_LocationID]
,[ws_name]
,[new_BillingManageruserName]

Hello,
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'm having a brain freeze.
I seem to recall that there is a system stored procedure that lists table objects and the "depth" of their dependencies. Something like:
table name 3
table 2 name 3
table 3 name 2
table 4 name 1
table 5 name 0
The results show the name of the table object and the numerical depth of dependencies (ie, if the table had no foreign keys, the depth would be 0).
Does this ring a bell with anyone? I've googled, but my google-shui is weak today.
Regards,
hmscott

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.
Here is the code:
SELECT
fs.TransactionId
,fs.DateKey
,dc.FirstName
,dc.LastName
,dc.Company
[code]....
Due to case by statement and having multiple category I have to use multiple group by.
select TransactionId
,DateKey
,FirstName
,LastName
,Company
,City
,Sum(CategoryAPurchase) CategoryAPurchase

5 1 4
6 0 6
7 1 6
8 2 7
9 3 8
10 4 9
11 0 11
As you can see even the parent element has parentId(in this case id = parentid)
How can I select the lowest level data in the hierarchy and get this result:
Id Level ParentId
3 2 2
5 1 4
10 4 9
11 0 11

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?

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.
SELECT
S.Id
, RMA
, PinSerial
, L4Serial
, L4Model

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?

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.

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?
Thanks
