I want to know how to create a recursive loop/function in SQL, I can’t seem to figure out how to do it.
The database table I am working with is simply the following:
SeedID, ThisParentSeedID
1, 0
2, 1
3, 1
4, 2
5, 4
6, 5
7, 6
8, 7
9, 7
10, 7
11, 10
12, 0
13, 0
14, 0
The example table above shows that SeedID 1 = the parent level of the data. SeedID 2 and 3 are children of SeedID 1, 4 is child of 2, 5 is child of 4... 12 13 and 14 are also parent levels (they are not children of anything).
I want to know how to create a SQL script that is “object oriented� in that I will not have to create as many levels of nested scripts as there are nested “children� in the data.
What I am wanting to figure out is, with a single script, “which sub-children are assigned to [@SeedID]�? So if this script was called, and @SeedID = 1, it would return (2,3,4,5,6,7,8,9,10,11). If @SeedID = 12, it would return null. If @SeedID = 7, it would return (8,9,10,11)
I have tried to keep my question and data as simple as possible for the sake of getting some feedback or help. If you want me to clarify or explain better, please ask me to!
Hi there. I want to avoid a cursur using a quite basing nested while loop. The problem is, that the outer index-variable (i) won't increment at all while the inner loop works perfectly.
This one should be quite easy to solve I guess, I'd be very happy if someone could give me a hint what I should try, though because I don't know what to try. The manual didn't help me much either, using CONTINUE and BREAKs didn't solve this problem for me.
My code: DECLARE @i INTEGER DECLARE @j INTEGER SET @i = 1 SET @j = 0
WHILE(@i<= 10) BEGIN WHILE(@j <= 100) BEGIN SELECT @i, @j, COUNT(*) as anz FROM mytable WHERE dim1 = @i AND dim2 = @j SET @j = @j + 1 END SET @i = @i + 1 END
Hi,I'm probably missing something obvious (either that or doing this totally wrong).I'm trying to use a nested loop to generate the following results:Unit Day1 Day2 Day3 Day4 Day5Name1 25 45 89 54 76Name2 48 54 81 74 98What I have so far is this:WHILE @FCount < @TotalFoodUnitsBEGINSELECT (SELECT Unit FROM tbl_acc_FoodVenues WHERE UnitID = (@FCount + 1)) AS Unit WHILE @FDCount < @Days BEGIN SELECT (SELECT FdRevenue_a FROM tbl_acc_aud_SportsAudits WHERE AudDate = DATEADD(day, @FDCount, @pdStartDate)) AS Rev SET @FDCount = @FDCount + 1 END SET @FCount = @FCount + 1ENDAny suggestions please
I have came across a situation - When there are no indices on the tables and if we force SQL server to use the "Nested Loop" joins, the query becomes very slow. Since there are no indices then Nested loop join should not be used.
The background for this problem is - Analysis services is sending some query to SQL server while doing the cube processing. SQL server is using Nested loop joins even though there are no indices on any of the tables. Is there any way by which we can force the SQL server/Analysis services not to use Nested loop joins since there are no indices in any of the tables.

i'm running the following code on Ms SQL Server 2000, Query Analyzer to analyze the result of Nested Loop Join.
SET STATISTICS PROFILE ON GO SELECT pdN.ProductID, pdN.ProductName, spN.CompanyName, spN.ContactName FROM dbo.ProductsNew pdN INNER JOIN dbo.SuppliersNew spN ON pdN.SupplierId = spN.SupplierId GO
but the execution plan give me the following result :-
I need to create a query to list all the subfolders within a folder.
I have a database table that lists the usual properties of each of the folder.
I have another database table that has two columns
1. Parent folder 2. Child folder
But this table maintains the parent child relationship only to one level.
For example if i have a folder X that has a subfolder Y and Z. And Y has subfolders A and B. and B has subfolder C and D and C has subfolder E and F
The database table will look like
parentfolder child folder X Y X Z Y A Y B B C B D C E C F
I want to write a query which will take a folder name as the input and will provide me a list of all the folders and subfolders under it. The query should be based on the table (parent - child) and there should not be any restriction on the subfolder levels to search and report for.
I have been banging my head to do this but i have failed so far. Any help on this will be highly appreciated.

I have to automate a process that assigns sales leads to sales people.For example:Every day we buy a list of sales leads, it ranges in size from 50 -100 records.We have a team of sales people that also can range from 5 - 8 people.I need to take the new records and divide them evenly among the salespeople.If i get 50 records, and have 5 sales people, then each sales persongets 10 leads.--So, im guessing that I may need to have a nested loop inside this. Ihave tried it several different ways, but cant seem to get it quiteright.DECLARE @TotalRecordCount int, @TotalSalesPeopleCount int,@AmountForEach int, @LooperSalesPeoplerecords int,@LooperNewSalesLeadsRecords int, @SalesPersonID intSELECT @TotalSalesPeopleCount = COUNT(UserId)FROM SalesPeopleWHERE Active = 1--SELECT @TotalRecordCount = COUNT(*)FROM NewSalesLeads--SELECT @AmountForEach = (@TotalRecordCount/@TotalSalesPeopleCount)--SELECT @LooperSalesPeoplerecords = 1SELECT @LooperNewSalesLeadsRecords = 1--WHILE @LooperSalesPeoplerecords <= @TotalSalesPeopleCountBEGINWHILE @LooperNewSalesLeadsRecords <= @TotalRecordCountBEGINSELECT @SalesPersonID = (SELECT UserIDFROM SalesPeopleWHERE UniqueId = @LooperSalesPeoplerecords)SELECT @LooperSalesPeoplerecords =(@LooperSalesPeoplerecords + 1)UPDATE SalesLeadsSET SalesPerson_ID = @SalesPersonIDWHERE UNIQUEID = @LooperSalesPeoplerecordsSELECT @LooperSalesPeoplerecords =(@LooperSalesPeoplerecords + 1)ENDEND----Table structuresCREATE TABLE [dbo].[SalesPeople] ([SalesPerson_ID] [int] NOT NULL ,[FirstName] [varchar](20)NOT NULL) ON [PRIMARY]--INSERT INTO SalesPeople (SalesPerson_ID,FirstName) VALUES (26, 'Bill')INSERT INTO SalesPeople (SalesPerson_ID,FirstName) VALUES (28, 'Bob')INSERT INTO SalesPeople (SalesPerson_ID,FirstName) VALUES (37,'Chris')------------------------------------------------CREATE TABLE [dbo].[SalesLeads] ([SalesLeadID] [int]NOT NULL ,[SalesPerson_ID] [int]NOT NULL) ON [PRIMARY]--INSERT INTO SalesLeads (SalesLeadID,SalesPerson_ID) VALUES (1001,0)INSERT INTO SalesLeads (SalesLeadID,SalesPerson_ID) VALUES (1002,0)INSERT INTO SalesLeads (SalesLeadID,SalesPerson_ID) VALUES (1003,0)INSERT INTO SalesLeads (SalesLeadID,SalesPerson_ID) VALUES (1004,0)INSERT INTO SalesLeads (SalesLeadID,SalesPerson_ID) VALUES (1005,0)INSERT INTO SalesLeads (SalesLeadID,SalesPerson_ID) VALUES (1006,0)------------------------------------------------So in this case, all 3 salespeople should receive 2 salesleads each.I dummied this down quite a bit. It actually ends up being more like15 sales people, and about 400,000 sales leads. But it should work onany level.Thanks for any help you might shed on this.

I have two queries that seem to be the same, but perform very differently. The first query runs very fast (7000+ records returned in <1 sec.). The execution plan shows that it uses a nested loop with index seeks on both tables.
select * from t_loadbasic
where ld_nbr in (select ld_nbr from t_tripcombined where comp_date between '11/1/07' and '11/05/07')
The second query is almost the same, save the fact that it uses date variables instead of hard dates. The execution plan shows that it uses a hash match instead of a nested loop with an index scan on the main table (t_loadbasic). This query takes about 12 seconds to run.
declare @startdate datetime
,@enddate datetime
set @startdate = '11/1/07'
set @enddate = '11/5/07'
select * from t_loadbasic
where ld_nbr in (select ld_nbr from t_tripcombined where comp_date between @startdate and @enddate)
I'm trying to figure out why the database executes these two statements so differently. BTW, I've tried switching the order of the tables. I've tried using joins instead of a subquery. The execution plan seems completely dependant on the use of variables. I can attach the execution plans if necessary.
I apologize if this is too simple a question, but I couldn't find an answer on any forums, web searches or BOL. Thanks in adavance.
Hi friends, I've been stumped on this for almost a week now. Everything works in the stored procedure code below except for the 'INSERT INTO @Uppdates' block of code. I have a SQL Analyzer test driver and when the code gets to the SELECT statement below the INSERT INTO @Updates line the value of the select line is displayed on the screen and nothing gets written to @Updates.

Hello Folks,I encountered a problem with SQL server 2000 and UDFs.I have a scalar UDF and a table UDF where I would like the scalar UDFto provide the argument for the table UDF like in:SELECT*FROMtransaction_tWHEREtrxn_gu_id in (select get_trxns_for_quarter(get_current_quarter( GetDate() ) ))'get_current_quarter' returns an integer which is a GUID in a tablecontaining business quarter definitions, like start date, end date.'get_current_quarter' is a scalar UDF.'get_trxns_for_quarter' will then get all transctions that fall intothat quarter and return their GUID's in a table.'get_trxns_for_quarter' is a table UDF.This doesn't seem to work at all. Regardless whether I provide thenamespace (schema) calling the scalar UDF or not. Error message isjust different.Both functions operate correctly invoked un-nested.The whole expression does work fine if I turn 'get_trxns_for_quarter'into a scalar UDF as well, e.g. by returning just one trxn_gu_id withe.g. MAX() in a scalar datatype. But of course that's no good to me.It also works fine if I select the result of 'get_current_quarter'into a variable and pass that variable into 'get_trxns_for_quarter'.But that's no good to me either since then I cannot use the wholething embedded into other SELECT clauses.Both UDF's are non-deterministic but I couldnt see how that would havean impact anyway.Never mind the syntax on that example or anyhting, I tried all theobvious and not so obvious stuff and it really seems to come down tothe fact that one UDF is scalar and the other one is not. However, Idid not come across any type of information saying that this cannot bedone.Have you any ideas?Any help would be greatly appreciated.Carsten
I am trying to execute a UDF in an Execute SQL Task within a Foreach loop.
I have an Execute SQL task to get the dataset (Firstname, Lastname, CompanyID) which is going into a full result set called @PendingPar. The Foreach Loop is set to a Foreach ADO Enumerator against @PendingPar and I have created 3 variables at the Foreach Loop scope level called @Firstname (String), @Lastname (String) and @CompanyID (Int32). These are mapped in the Foreach Loop as index 0,1 and 2.
Within the Foreach Loop I have an Execute SQL Task with the sql command
select dbo.udf_GetParTitle (?,?,?)
In the parameter mapping I have Variable Name = User::Firstname Direction = Input Data Type = VARCHAR and Parameter Name = 0, User::Lastname, Input, VARCHAR, 1 and User::CompanyID, Input, VARCHAR,2
Finally the UDF returns a @NewPar value so i have the result set in the execute sql task to Single Row which goes into variable @NewPar. This @newPar will be used later but I cannot get the first bit to work yet.
the error message i get back is
Error: 0xC002F210 at Execute SQL Task 1, Execute SQL Task: Executing the query "select dbo.udf_GetParTitle (?,?,?)
" failed with the following error: "Syntax error, permission violation, or other nonspecific error". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly.
Task failed: Execute SQL Task 1
the initial execute sql task where the dataset is selected works fine but it is within the foreach loop that it fails.
I have a table called Tbltimes in an access database that consists of the following fields:
empnum, empname, Tin, Tout, Thrs
what I would like to do is populate a grid view the a select statement that does the following.
display each empname and empnum in a gridview returning only unique values. this part is easy enough. in addition to these values i would also like to count up all the Thrs for each empname and display that sum in the gridview as well. Below is a little better picture of what I€™m trying to accomplish.
Tbltimes
|empnum | empname | Tin | Tout | Thrs |
| 1 | john | 2:00PM | 3:00PM |1hr |
| 1 | john | 2:00PM | 3:00PM | 1hr |
| 2 | joe | 1:00PM | 6:00PM | 5hr |
GridView1
| 1 | John | 2hrs |
| 2 | Joe | 5hrs |
im using VWD 2005 for this project and im at a loss as to how to accomplish these results. if someone could just point me in the right direction i could find some material and do the reading.
I have this function in access I need to be able to use in ms sql. Having problems trying to get it to work. The function gets rid of the leading zeros if the field being past dosn't have any non number characters.For example:TrimZero("000000001023") > "1023"TrimZero("E1025") > "E1025"TrimZero("000000021021") > "21021"TrimZero("R5545") > "R5545"Here is the function that works in access:Public Function TrimZero(strField As Variant) As String Dim strReturn As String If IsNull(strField) = True Then strReturn = "" Else strReturn = strField Do While Left(strReturn, 1) = "0" strReturn = Mid(strReturn, 2) Loop End If TrimZero = strReturnEnd Function
I need to be able to pass the output of a function to another function as input, where all functions involved are user-defined in-line table-valued functions. I already posted this on Stack Exchange, so here is a link to the relevant code: [URL] ...
I am fairly certain OUTER APPLY is the core answer here; there's *clearly* some way in which does *not* do what I need, or I would not get the null output you see in the link, but it seems clear that there should be a way to fool it into working.
Can you give a whole SQL statement an alias so you can use it later?
Eg.
SELECT * FROM Employees WHERE age < 19 -- Could I call the above statement something like 'statement1' to use below as shown
SELECT * FROM Employees WHERE age < 25 AND NOT IN (statement1)
Soin effect I get a nested statement. The reason I am asking about aliases is because this would need to be repeated for, E.g. age < 30 Then age < 35 and so on and so forth.
So basically, I just want to alias a qhole SQL statement
Hi all,I have a query that looks like so:SELECT GLDCT AS [Doc Type], GLDOC AS DocNumber, GLALID ASPerson_NameFROM F0911WHERE (GLAID = '00181913')However by stipulating that GLAID = GLAID I cannot get the person_nameas not all the GLALID fields are filled in. from my reading of thehelpdesk I have a felling that a nested query might be the way to goor a self-join but beyond this I am lost!?Many thanks for any pointers in advance.Sam
I am trying to do some nested IF ELSE conditions. I get an error saying 'Error near work Begin'. Below is teh query and the variables comes in thru cursor.
Can somebody advise me on this and also let me know the best practices and alternative to this if any.
IF (@CCTable = 'Claiminassoc') BEGIN IF ( @ClaimCenterField = 'ClaimID' AND @VALUE ='Claim') BEGIN UPDATE dbo.Table SET ColName = 'Y' WHERE ID = @ID AND CCTable = 'Claiminassoc' AND CCField = 'ClaimID' AND DWField = 'CatastropheDesignationFlag' END END
ELSE IF (@CCTable = 'EmploymentData') BEGIN IF (@VALUE ='TRUE') BEGIN UPDATE dbo.Table SET ColName = 'Y' WHERE ID = @ID AND CCTable = 'Claim' AND CCField = 'WagePaymentCont' END
ELSE IF (@VALUE ='FALSE') BEGIN UPDATE dbo.Table SET ColName = 'N' WHERE ID = @ID AND CCTable = 'Claim' AND CCField = 'WagePaymentCont' END END
I have a challenge, which seems like it is probably trivial, but SQL chops are not up to the task, and I am hoping one of you hot-shot DBAs can throw me a bone!
I have a query that populates an OLAP Time dimension table (basically one row per day of the year over several years). What I want to do is expand that table to include each hour of each day over the time span.
The CTE I am using for the day population is:
Code Snippet WITH dates(date) -- A recursive CTE that produce all dates between 2006 and 2057-12-31 AS ( SELECT cast('2006' AS dateTime) date -- SQL Server supports the ISO 8601 format so this is an unambigious shortcut for 1999-01-01 UNION ALL -- http://msdn2.microsoft.com/en-us/library/ms190977.aspx SELECT (date + 1) AS date FROM dates WHERE date < cast('2058' AS dateTime) -1 )
What I wanted to do was something like:
Code Snippet WITH hours(hr) AS ( SELECT (DATEPART(hh,date) hr UNION ALL SELECT (hr + 1) AS hr FROM hours WHERE hr < 24 )
inserted just after
Code Snippet FROM dates
in the initial CTE. But from what I have read, it seems as though nested CTEs are not allowed.
Can someone pls advise the maximum number of nested IIF statements allowed in a VS 2005 report builder layout textbox expression? I seem to be hitting a wall at about 10, but cannot find verification. In case the limitation is by characters, the full expression would run about 3,500. Any other limitations which may have a bearing?
Hi all! I have a problem with my stored procedure, What I'm trying to do here is whenever a user tries to register, the stored procedure will check if the username already exists, and if not it'll now check if the email has already been entered into the database then if not the stored procedure will go ahead and insert the values into the database. *If the username already exists it'll return -1, and if the email already exists then return -2.
SELECT Username FROM UserAccount WHERE Username = @UsernameIF @@ROWCOUNT = 0 SELECT Email FROM UserAccount WHERE Email = @Email IF @@ROWCOUNT = 0 BEGIN
INSERT INTO UserAccount (Username, Password, Email, FirstName, LastName, Gender, BirthDate, Country, State, Zip, AdditionalInfo) VALUES (@Username, @Password, @Email, @FirstName, @LastName, @Gender, @BirthDate, @Country, @State, @Zip, @AdditionalInfo) END ELSE BEGIN
