how recursive CTE works...Synthesise table with non-recursive CTE
;WITH Employee (ID, Name, MgrID) AS
(
SELECT 1, 'Keith', NULL UNION ALL
SELECT 2, 'Josh', 1 UNION ALL
SELECT 3, 'Robin', 1 UNION ALL
SELECT 4, 'Raja', 2 UNION ALL
[code]....
the first part query will return one row
IDNameMgrIDnLevelFamily
1KeithNULL11
then this result set using after union all query .how the level + 1 condition is working ? and how its return values .
Hi All, I have a requirement here to import data from XML file to SQL Database. The XML schema contains of various elements and one of the element is recursive ie. Parameter node contains parameter node within it and it can have n number of iterations. I have given the sample schema below:
But all the nodes contain the data which has to be imported to a single table dbo.Parameters. I cannot use Union ALL since i dont know how many iterations I will have in the file. Is there any way to do this operation in Data Flow Task using XML Source? Can anyone help me on this?
Category_ID Number Parent_ID Number <----Category_ID reports to this colum Category_Name Varchar....
MY QUERY <---I replaced the query above with my data ============================= WITH Hierarchy(Category_ID, Category_Name, Parent_ID, HLevel) AS ( SELECT Category_ID, Category_Name, Parent_ID, 0 as HLevel FROM Dir_Categories UNION ALL SELECT SubCategory.Category_ID , SubCategory.Category_Name, SubCategory.Parent_ID, HLevel + 1 FROM Dir_Categories SubCategory INNER JOIN Hierarchy ParentCategory ON SubCategory.Parent_ID = ParentCategory.Category_ID ) SELECT Category_ID, Category_Name = Replicate('__', HLevel) + Category_Name, Parent_ID, HLevel FROM Hierarchy
My OUTPUT============
All the categories under reporting to Parent_ID 0 or continuous, then the ones reporting to 1 and so fourth. Subcategories are not showing within their main categories. I AM GOING NUTS WITH THIS.
I have a parent-child table, and i want to copy subtrees of it, so for instance this would be the starting point: (id, parentId, label) 0, null, World 1, 0, US 2, 1, NY 3, 0, UK 4, 3, London
now i want to copy object 3 (UK) and it's children, so i would get 0, null, World 1, 0, US 2, 1, NY 3, 0, UK 4, 3, London 5, 0, UK_copy 6, 5, London_copy
I have this sproc:
Code Snippet
alter proc CopyObject
(@ObjectId int,
@NewParentId int)
as
declare @NewId int,
@NewName varchar
select @NewId = max(Id) + 1 from Object
select @NewName = [Name] + 'copy' from [Object] where Id = @ObjectId
-- copy object
INSERT INTO [Object]
([Id]
,[Name]
,[ParentId]
select @NewId,
@NewName,
@NewParentId
from [Object]
where Id = @ObjectId
-- copy children and set their parent to the newly created object
declare c cursor fast_forward for
select Id
from [Object]
where ParentId = @ObjectId
declare @ChildId int
open c
fetch next from c into @ChildId
while @@fetch_status = 0
begin
exec CopyObject
@ObjectID = @ChildId,
@NewParentId = @NewId
fetch next from c into @ChildId
end
close c
deallocate c
But htis throws an error that the cursor already exists:
Msg 16915, Level 16, State 1, Procedure CopyObject, Line 66
A cursor with the name 'c' already exists.
Msg 16905, Level 16, State 1, Procedure CopyObject, Line 72
The cursor is already open.
I've tried to think of an approach without cursors, but i can't figure it out. Because on the first pass, the new parentId will be the same as the parentId of the object to be copied. But the copies of the children of this first original object should have the parentid set to id of the copied object, and so all the way down the tree.
I need limit on recursion. I have a recursion query. which gives me a parent child record set. I want my application to fetch only top 100 rows. In those 100 rows the parent child set should not get break. Even if it gives 105 rows also fine but it should have entire parent child structure.
If you see my below table. where null is the table which dont have parents but have the child.
And it is temp table #test1and my recursive query.
;WITH Cte AS ( SELECT ItemID,ParentItemID,CAST(ItemID AS VARCHAR(200)) [path] FROM #Test1 WHERE ParentItemID IS NULL UNION ALL SELECT t.ItemID,t.ParentItemID, CAST([path]+'.'+CAST(t.ItemID AS VARCHAR(20)) AS VARCHAR(200)) FROM Cte c JOIN #Test1 t ON C.ItemID=t.ParentItemID ) SELECT * FROM Cte ORDER BY path ASC
I am using the following code to get the next immediate parent of a customer in the hierarchy and it works fine. However, it works only for one customer at a time (i made this a scalar function and I pass the customer id as shown below).
How can I modify this so that i can get each customer and its next immediate parent (all of them in one shot in a single data set)?
WITH my_cte (CustomerID, ParentID, Level) AS ( SELECT CustomerID, ParentID, 0 AS Level FROM [dbo].MyTable WHERE CustomerID = @CustomerID
UNION ALL SELECT CustomerID, ParentID, Level + 1 FROM [dbo].MyTable e INNER JOIN my_cte AS cte ON e.CustomerID = cte.ParentID )
select CustomerID from my_cte WHERE Level <> 0 AND Level = (SELECT MIN(Level) FROM my_cte WHERE Level <> 0)
I'm trying to find it difficult to use recursice CTEs or better solution for a special request below. There are two tables 1) @sizes serves as a lookup or reference for right drive and 2) @test is sample data with different sizes. Assume that I want to evenly distribute the drive letters from table1 to table2 by checking the size available.
E.g.: for the first record in @test; id = 1 where the size is 50 and it fits in Y: drive -- left over space in Y: = 50
id=2, size 2.5, space available from left over = 50 - 2.5 = 47.5 which again fits into Y: id = 3, size 51, cannot in fit in Y: drive as there is enough space in Y: to allocate (51 > 47.5)
so pick the next drive check on availability again
DECLARE @sizes TABLE (id TINYINT, size DECIMAL(5,2), drive VARCHAR(3)) INSERT INTO @Sizes SELECT 1,100.00,'Y:' UNION ALL SELECT 2,80.85,'Z:'
[Code] ....
-- My output should look like
col1 , val , path A 50 Y: B 2.5 Y: C 51 Z: D 2.6 Y: E 52 Z: F 2.7 Y:
- Sequence container with multiple tasks - Send Mail Task 1 if my container finish with success (green constraint) - Send Mail Task 2 if my container finish with Fail (red constraint)
Each task in my container is configured with "FailParentOnFailure = true" so if one task fail may sequence container fails.
Every think works fine if there is no error and I receive mail notification for success status, however if there is an error in one task may container fails (it turns red) but "Send Mail Task 2" component is not executed and I don't receive any notification
Did I miss something in my settings? Thank you a lot for your help
I need to write recursive query to find child of a parent until the last leaf. Below is my code.
;WITH Parent AS( SELECT [ParentID],Value FROM[DynamicColsValues_TP1] WHEREValue IS null UNION ALL SELECT t1.[ParentID],T1.Value, FROM DynamicColsValues_TP1 t1 INNER JOIN Parent t2 ON t1.[ParentID]=t2.[ParentID] ) SELECT * FROM Parent option (maxrecursion 0)
When I execute this code. It is returning me millions of rows. Whereas i have only 20 rows in a table max 40 rows it should return.
Hello, I'm trying to do something simple but can't make it work. I want to use the result of this sql "Select MAX(Stoptime) AS LatestStop FROM Stoptime" and use it in "Delete from Stoptime Where Stoptime > ?" but here with just the date. How do I set this up with parameters in the Control Flow in Integration Services?
I am having problem to apply updates into this function below. I triedusing cursor for updates, etc. but no success. Sql server keeps tellingme that I cannot execute insert or update from inside a function and itgives me an option that I could write an extended stored procedure, butI don't have a clue of how to do it. To quickly fix the problem theonly solution left in my case is to convert this recursive functioninto one recursive stored procedure. However, I am facing one problem.How to convert the select command in this piece of code below into an"execute" by passing parameters and calling the sp recursively again.### piece of code ############SELECT @subtotal = dbo.Mkt_GetChildren(uid, @subtotal,@DateStart, @DateEnd)FROM categories WHERE ParentID = @uid######### my function ###########CREATE FUNCTION Mkt_GetChildren(@uid int, @subtotal decimal ,@DateStart datetime, @DateEnd datetime)RETURNS decimalASBEGINIF EXISTS (SELECTuidFROMcategories WHEREParentID = @uid)BEGINDECLARE my_cursor CURSOR FORSELECT uid, classid5 FROM categories WHERE parentid = @uiddeclare @getclassid5 varchar(50), @getuid bigint, @calculate decimalOPEN my_cursorFETCH NEXT FROM my_cursor INTO @getuid, @getclassid5WHILE @@FETCH_STATUS = 0BEGINFETCH NEXT FROM my_cursor INTO @getuid, @getclassid5select @calculate = dbo.Mkt_CalculateTotal(@getclassid5, @DateStart,@DateEnd)SET @subtotal = CONVERT (decimal (19,4),(@subtotal + @calculate))ENDCLOSE my_cursorDEALLOCATE my_cursorSELECT @subtotal = dbo.Mkt_GetChildren(uid, @subtotal,@DateStart, @DateEnd)FROM categories WHERE ParentID = @uidENDRETURN @subtotalENDGORod
My Requirement is Update Table 1 set Column::No=Table 2.ID
based on Exact Match of
Table1.Name=Table2.Name and
Table1.Add=Table2.Add
It means Get back the Id for Source Table 1
2nd Data flow Source(Table1:Name, Add,No) |
--LOOKUP(Table2:Name, Add::Matched Look Columns Name, Add and Tick Mark on ID) |(Match)
-->OLEDB Command: update Table1 set N0=? where RowID=?(Here Param_0= NO ,Param_1=RowID)
Here My Issue is if Table 1 had Duplicates(same Name, Add, but Row Id is different it is Updating Same ID for Table 1.No It means Get Back ID correctly not updating Result::
Table 1:
------- ----- ---- ---- Name Add No RowID ------- ----- ---- ------- aa #a-1,India 1 10 bb #a-1,India 2 11 aa #a-1,India 1 12
Hi all, I am new to transact-sql and hoped that someone here might be able to help. I have a db with a field called "part" ... part contains text in the format:
xxxxx-xx-xxxxx
(the number of x's before or after each hyphen vary) such that I could have xxx-xxxxx-xxx as the part.
Someone wrote this transact-sql to take my current "part" field and move it to three different part fields ... a,b,c
If xxxxx-xx-xxxxx was the part in the original db, then a would contain xxxxx .. b contains xx ... c contains xxxxx
Make sense? Here is the code. It doesn't work and I can't seem to figure out why! It looks like it is just trying to find the hyphens and cut out the text from that... but it fails with an error that says "invalid length parameter passed to the substring function". Note, if I take off the "-1" from each line below... then the function works but produces the wrong data.
char(45) = "-" (hyphen)
UPDATE [dbo].[parts] SET a = SUBSTRING(part,1,CHARINDEX(CHAR(45),part)-1), b = SUBSTRING(part,CHARINDEX(CHAR(45),part)+1,CHARINDEX(CHAR(45),RIGHT(part,LEN(part)-CHARINDEX(CHAR(45),part)))-1), c = SUBSTRING(part,CHARINDEX(CHAR(45),RIGHT(part,LEN(part)-CHARINDEX(CHAR(45),part)))+CHARINDEX(CHAR(45),part)+1,LEN(part)) GO
Does anyone know what I can do to fix this or is it much more difficult to do than what it seems?
In the following t-sql 2012 merge statement, the insert statement works but the update statement does not work. I know that is true since I looked at the results of the update statement:
Merge TST.dbo.LockCombination AS LKC1 USING (select LKC.comboID,LKC.lockID,LKC.seq,A.lockCombo2,A.schoolnumber,LKR.lockerId from [LockerPopulation] A JOIN TST.dbo.School SCH ON A.schoolnumber = SCH.type
[Code] ...
Thus can you show me some t-sql 2012 that I can use to make update statement work in the merge function?
I am wanting to create a custom workday calendar to show Monday - Friday as a workday, then go back and update a few holidays as non-workdays. This is the syntax I have to start with, but it is presenting with an error:
Msg 241, Level 16, State 1, Line 21 Conversion failed when converting date and/or time from character string.
What should I alter?
CREATE TABLE dbo.CreateCustomCalendar ( wk_Date INT IDENTITY NOT NULL, FullDate DATETIME NOT NULL, WeekDayName VARCHAR(9) NOT NULL, IsWorkday varchar(20) NOT NULL )
Hi, Recently I have been trying to write a script in order to redo this entire database, it's actually only about rectifying column and table names as well as a few erroneous relations, etc. The idea is that the actual data is okay it's just the organization that is completely messed up (spaces in column and table names, etc.)
Anyway my problem is this, a part of this script is about mass-renaming columns and tables the code is as follows in the Query Analyzer:
When I barely analyze the code (Ctrl+F5) it gives me the following error: Serveur : Msg 170, Niveau 15, État 1, Ligne 2 Ligne 2 : syntaxe incorrecte vers 'sp_rename'.
Which would roughly translate into: Server : Msg 170, Level 15, State 1, Line 2 Line 2 : Incorrect syntax near 'sp_rename'
When I execute it, it gives the same error. Why does it do that when i give it the two lines while if i enter the lines one by one it works just fine. How is a SCRIPT supposed to work if I have to "baby-feed" every statement separately.
PS: i am working on SQL Server 2000 (in Query Analyzer menu ?/About .. it says SQL Version 8.00.194
I have this sql stored procedure in SQL Server 2012:
ALTER PROCEDURE [dbo].[CreateBatchAndSaveExternalCodes] @newBatches as dbo.CreateBatchList READONLY , @productId int , @cLevelRatio int , @nLevelRatio int AS set nocount on;
Below is the stored procedure i have it works fine if i have 1 value passed to @invited_by but i want to modify but i want this code to be working for multiple inputs .Lets say if i do
exec [dbo].[sp_GetInvitationStatusTest] 'Test1 . I get the desired output but i want this procedure to work for exec [dbo].[sp_GetInvitationStatusTest] 'Test1,Test2'. USE [merck_acronyms] GO
Basically, I am asking if it is possible to use SSMS (Query Analyzer window) with Informix. I am thinking linked server. If I have the ODBC driver installed on my workstation (win 7 pro VM workstation -- SSMS on same VM machine) is this doable? Do I just do the standard linked server routine or is there a special way (if it is even doable).
I created a dbo.Calendar table that stores dates and a work day flag (1=work day, 0=non-work day) so I can use it to calculate the next business date from a date using a function. I'm using a while group to count only the work days and a couple other internal variables but I'm not sure if I can even use them in a function.
Assuming Sats & Suns are all non-work days in April 2014, if my @WorkDays = 10 for 10 work days and my @DateFromValue - 4/1/2014, I would expect my return date to be 4/15/2014.

I need to pass a parameter from control flow to data flow. The data flow will use this parameter to get data from a Oracle source.
I have an Execute SQL task in control flow to assign value to the Parameter, next step is a data flow which will need take a parameter in the SQL statement to query the Oracle source,
The SQL Looks like this:
select * from ccst_acctsys_account
where to_char(LAST_MODIFIED_DATE, 'YYYYMMDD') >?
THe problem is the OLE DB source Edit doesnt have anything for mapping parameter.
I have an Execute SQL Task that returns a Full Rowset from a SQL Server table and assigns it to a variable objRecs. I connect that to a foreach container with an ADO enumerator using objRecs variable and Rows in first table mode. I defined variables and mapped them to the columns.
I tested this by placing a Script task inside the foreach container and displaying the variables in a messagebox.
Now, for each row, I want to write a record to an MS Access table and then update a column back in the original SQL Server table where I retreived data in the Execute SQL task (i have the primary key). If I drop a Data Flow Task inside my foreach container, how do I pass the variables as input to an OLE DB Destination on the Data Flow?
Also, how would I update the original source table where source.id = objRects.id?
Thank you for your assistance. I have spent the day trying to figure this out (and thought it would be simple), but I am just not getting SSIS. Sorry if this has been covered.
Dear All! My package has a Data Flow Task. In Data Flow Task, I use a Script Component and a OLE BD Destination to transform data from txt file to database. Within Data Flow Task, I want to call File System Task to move file to a folder or any Task of "Control Flow" Tab. So, Does SSIS support this task? Please show me if any Thanks
I'm currently setting variables at the package level with an ExecuteSQL task. This works fine. However, I'm now starting to think about restartability midway through a package. It would be nice to have the variable(s) needed in a data flow set within the data flow so that I only have to restart that task.
Is there a way to do that using an SQL statement as the source of the value in a data flow?
OR, when using checkpoints will it save variable settings so that they are available when the package is restarted? This would make my issue a moot point.
Hi all! I recently started working with SSIS and one of the things that is puzzling me the most is what's the best way to go:
A small control flow, with large data flow tasks A control flow with more, but smaller, data flow tasksAny help will be greatly appreciated. Thanks, Ricardo

Hello Everyone, I have a purchase order table that holds say 2 columns. PO and OrgPO. That is Purchase Order # and Original Purchase Order # respectively. Assume i have the following rows in the table. PO OrgPO -- ------ po1 NULL co1 po1 co2 co1 co3 co2 po2 NULL cpo1 po2 po3 NULL Now what i would like to report in the output is the PO and along with the lastly generated change order for that po. For eg, PO LastCO -- ------ po1 co3 po2 cpo1 po3 po3 Currently i 'm using function to achieve this effect and i believe this is not the efficient way. I would like to generate this in a much efficient way. Please help me to achieve this.
