I have a parameter which should take multiple values into it and pass that to the code that i use. For, this i created a parameter and temporarily for testing i am passing some values into it.Using a dynamic SQL i am converting multiple values into multiple records as rows into another variable (called @QUERY). My question is, how to insert the values from variable into a table (table variable or temp table or CTE).OR Is there any way to parse the multiple values into a table. like if we pass multiple values into a parameter. those should go into a table as rows.
Is it possible in SQL 2000 to return a table variable from dynamic sql? We need to have some code that looks kind of like this:
declare @qry varchar(8000)
declare @sourcetable varchar(100) -- name of source table
declare @mytable table (ID_Num int identity(1,1), Child_Key varchar(100))
set @sourcetable = (select tablename from tblConfig where app = 1)
set @qry = 'insert into @mytable
select * from @sourcetable'
execute (@qry)
if (select count(*) from @mytable) > 0
begin
'insert into myFinalTable
select * from @mytable where blah blah blah
I can get the first part to work by declaring the table variable (mytable) in the dynamic sql, but I can't figure out how to return the table object.
I tried to create a dynamic table, fill in it and return it as recordset. The codes as this:
Declare @tbl Table(id int, name varchar(100), age int)
Insert Into @tbl(id, name, age)
Values(1, 'James, Lee', 28),
(2, 'Mike, Richard', 32),
(3, 'Leon Wong', 29)
Select * From @tbl Order By age
It works well in "SQL Query Ananizer". But return no records in ASP page.
Empid 1 has 2 entries for the date 09/01/2015 and my left join returns both of those entries. What do I need to alter to make it so that only the most recent entry is returned not both entries?

I don't know why this is so difficult. What I want to do is take a table name as a parameter to build a query and get an integer value from the result of the query. But from all of the research I have been doing, Dynamic SQL is bad in SQL server because of SQL Injections. But my users are not going to be supplying the table names.
Things I have learned:
- SQL Functions cannot use Exec to execute query strings.
- SQL Functions can return a concatenated string that could be used by a stored procedure to Exec the query string.
So how can I write a stored procedure that will
1. take a parameter
2. Pass the parameter to a function that will return a string
3. Execute that string as SQL
4. Get a return value from that SQL statement
5. Then finally, from a View, how can I pass a parameter to the stored procedure and get the returned value from the stored procedure to be used as a field in the View?
Numbers 3, 4, and 5 are where I am really stuck. I guess I don't know the proper syntax and limitations of SQL Server.
I have
Customer table, tblCust: ID; Name
1 Peter2 Mary
Product table, tblProduct: ID; Name
1 Banana2 Orange3 Apple
Order tblOrder, tblOrder: CustID; ProductID; Amount
1 ;2 ;$20 – means Peter ordered $20 oranges
How do I write the SQL query so that the values in tblProduct become column, currently I have 20 items in that table. So, it will return something like this according to the information that I provide above?
Name Banana Orange Apple
Peter 0 20 0
We have a previous SQL 2012 cluster that emails us when a new database is added. I am unable to figure out why we get this error any time we add a new database to it, and also it prevents us from adding a new availability group to this cluster because of this error.
I also am unable to figure out what profile it is talking about as this was setup before me and I am not a DBA.
I've to write a function to return a comma delimited values from a table columns
If a table has Tab1 ( Col1,Col2,Col3).
E.g. as below ( the columnName content I want to use as columns for my pivot table
CREATE FUNCTION [RPT].[GetListOfCol]
(
@vCat NVARCHAR(4000)

RETURNS @PList
AS
BEGIN
SELECT @PList += N', [' + [ColumnName] +']'
FROM [ETL].[TableDef]
WHERE [IsActive] = 1
AND [Category] = @vCat
RETURN;
END;
I want out put to be as below, I am getting this output from the select query independently by declaring @Plist variable and passing @vcat value, now I want it to be returned from a function when called from a select query output ,Colum1,column2,....
Is there any way to convert a bind variable, which is a list of integer or string values, to nested table in MS SQL Server. I am looking for something like
CAST in Oracle, which converts a varray type column into a nested table. Do we have something like this in SQL Server.
in Oracle:
SELECT CAST(s.addresses AS address_book_t)
FROM states s
WHERE s.state_id = 111;
I have read about Table valued Parameter, but I am looking for another solution.
I would like to INSERT an array of integer into a table in MSSQL Server, then count the number of rows in the table with c++ using ODBC. Here you find my code to do this task:
#include <windows.h>
#include <stdlib.h>
#include <stdio.h>
#include<tchar.h>
#include <sql.h>
#include <sqlext.h>
#include<sqltypes.h>
[Code] ....
In my code, I would like to Insert the array and then count the number of rows:
SQLTCHAR Statement[] = _T("INSERT INTO information1(Wert1,Wert2) VALUES(?,?) select count(*) as a from information1 ") ;
Problem : My expectation is, that first 9 rows are inserted into table then comes 9 as result to user (if the table is empty) but this code returns me 1 if first the table is empty. If the table is not empty, it returns 1+number of existing rows in the table. If I take a look inside the table, the 9 rows are successfully inserted in it. Only the number of rows in the table is wrong.
Hint : If I monitor the database using SQL Profiler. It looks like this:
Why this statement doesn't work correctly?
I have tables and a function as representated by the code below. The names for objects here are just for representation and not the actual names of objects. Table RDTEST may have one or multiple values for RD for each PID. So the function GIVERD will return one or multiple values of RD for each value of PID passed to it.
When I run the following query, I get the required result except the rows for CID 500 for which PID is NULL in table T1. I want the rows for CID 500 as well with PID values as NULL.
SELECT A.CID,

I'm new to SSIS, but have been programming in SQL and ASP.Net for several years. In Visual Studio 2005 Team Edition I've created an SSIS that imports data from a flat file into the database. The original process worked, but did not check the creation date of the import file. I've been asked to add logic that will check that date and verify that it's more recent than a value stored in the database before the import process executes.
Here are the task steps.
[Execute SQL Task] - Run a stored procedure that checks to see if the import is running. If so, stop execution. Otherwise, proceed to the next step.
[Execute SQL Task] - Log an entry to a table indicating that the import has started.
[Script Task] - Get the create date for the current flat file via the reference provided in the file connection manager. Assign that date to a global value (FileCreateDate) and pass it to the next step. This works.
[Execute SQL Task] - Compare this file date with the last file create date in the database. This is where the process breaks. This step depends on 2 variables defined at a global level. The first is FileCreateDate, which gets set in step 3. The second is a global variable named IsNewFile. That variable needs to be set in this step based on what the stored procedure this step calls finds out on the database. Precedence constraints direct behavior to the next proper node according to the TRUE/FALSE setting of IsNewFile.
If IsNewFile is FALSE, direct the process to a step that enters a log entry to a table and conclude execution of the SSIS.
If IsNewFile is TRUE, proceed with the import. There are 5 other subsequent steps that follow this decision, but since those work they are not relevant to this post.
Here is the stored procedure that Step 4 is calling. You can see that I experimented with using and not using the OUTPUT option. I really don't care if it returns the value as an OUTPUT or as a field in a recordset. All I care about is getting that value back from the stored procedure so this node in the decision tree can point the flow in the correct direction.
CREATE PROCEDURE [dbo].[p_CheckImportFileCreateDate]
/*
The SSIS package passes the FileCreateDate parameter to this procedure, which then compares that parameter with the date saved in tbl_ImportFileCreateDate.
If the date is newer (or if there is no date), it updates the field in that table and returns a TRUE IsNewFile bit value in a recordset.
Otherwise it returns a FALSE value in the IsNewFile column.
Example:
exec p_CheckImportFileCreateDate 'GL Account Import', '2/27/2008 9:24 AM', 0
*/
@ProcessName varchar(50)
, @FileCreateDate datetime
, @IsNewFile bit OUTPUT
AS
SET NOCOUNT ON
--DECLARE @IsNewFile bit
DECLARE @CreateDateInTable datetime
SELECT @CreateDateInTable = FileCreateDate FROM tbl_ImportFileCreateDate WHERE ProcessName = @ProcessName
IF EXISTS (SELECT ProcessName FROM tbl_ImportFileCreateDate WHERE ProcessName = @ProcessName)
BEGIN
-- The process exists in tbl_ImportFileCreateDate. Compare the create dates.
IF (@FileCreateDate > @CreateDateInTable)
BEGIN
-- This is a newer file date. Update the table and set @IsNewFile to TRUE.
UPDATE tbl_ImportFileCreateDate
SET FileCreateDate = @FileCreateDate
WHERE ProcessName = @ProcessName
SET @IsNewFile = 1
END
ELSE
BEGIN
-- The file date is the same or older.
SET @IsNewFile = 0
END
END
ELSE
BEGIN
-- This is a new process for tbl_ImportFileCreateDate. Add a record to that table and set @IsNewFile to TRUE.
INSERT INTO tbl_ImportFileCreateDate (ProcessName, FileCreateDate)
VALUES (@ProcessName, @FileCreateDate)
SET @IsNewFile = 1
END
SELECT @IsNewFile
The relevant Global Variables in the package are defined as follows:
Name : Scope : Date Type : Value
FileCreateDate : (Package Name) : DateType : 1/1/2000
IsNewFile : (Package Name) : Boolean : False
Setting the properties in the "Execute SQL Task Editor" has been the difficult part of this. Here are the settings.

When I run this in debug mode with this SQL statement ...

When the above is run tbl_ImportFileCreateDate does not get updated, so it's failing at some point when calling the procedure.

The IsNewFile global variable is scoped at the package level and has a Boolean data type, and the Output parameter in the stored procedure is defined as a Bit. So what gives?
The "Possible Failure Reasons" message is so generic that it's been useless to me. And I've been unable to find any examples online that explain how to do what I'm attempting. This would seem to be a very common task. My suspicion is that one or more of the settings in that Execute SQL Task node is bad. Or that there is some cryptic, undocumented reason that this is failing.
Thanks for your help.
How can I insert the results of "set statistics profile on" into a table?
View 2 Replies View RelatedI have a stored procedure that selects the unique Name of an item from one table.
SELECT DISTINCT ChainName from Chains

Hello,
This is info that I am still not certain about and I just need to make sure, my gut feeling is correct:
A.
When a procedure is triggered upon reception of a message in a queue, what happens when the procedure fails and rolls back?
1. Message is left on the Queue.
2. is the worker procedure triggered again for the same message by the queue?
3. I am hoping the Queue keeps on triggering workers until it is empty.
My scenario is that my queue reader procedure only reads one message at a time, thus I do not loop to receive many messages.
B.
For my scenario messages are independent and ordering does not matter.
Thus I want to ensure my Queue reader procedures execute simultaneously. Is reading the Top message in one reader somehow blocking the queue for any other reader procedures? I.e. if I have BEGIN TRANSACTION when reading messages of the Queue, is that effectively going prevent many reader procedures working simultaneously. Again, I want to ensure that Service broker is effectively spawning procedures that work simultaneously.
Thank you very much for the time,
Lubomir
I have a table that I want to act as a queue.
It has no indexes and no key. Just one column.
Basically I want a stored procedure that will pull / return the first record off the queue (table) and delete it. I'd rather not use MSMQ for this.
There will be about 10 users trying to do this at the same time and will be trying to pull of about 15 times every second.
How can I do this and ensure that no two requests pull off the same row?
Thanks,
Kevin
I am trying to implement a very fast queue using SQL Server.The queue table will contain tens of millions of records.The problem I have is the more records completed, the the slower itgets. I don't want to remove data from the queue because I use thesame table to store results. The queue handles concurrent requests.The status field will contain the following values:0 = Waiting1 = Started2 = FinishedAny help would be greatly appreciated.Here is a simplified script to demonstrate what has been done.CREATE TABLE [dbo].[Queue] ([ID] [int] IDENTITY (1, 1) NOT NULL ,[JobID] [int] NOT NULL ,[Status] [tinyint] NOT NULL) ON [PRIMARY]GOCREATE INDEX [Status] ON [dbo].[Queue]([Status]) ON [PRIMARY]GOCREATE PROCEDURE dbo.NextItem@JobID integer,@ID integer outputASSELECT TOP 1 @ID = [ID]FROM Queue WITH (READPAST, XLOCK)WHERE (Status = 0) AND (JobID = @JobID)RETURNGO
View 6 Replies View RelatedI know we are not allowed to benchmark SQL Server but..... It would be nice to have material to present which demonstrates the performance gains using a queue compared to insert/delete in a SQL table.
Logically it seems faster to use a queue due to the conversation grouping locking and the service broker itself. But there seems to be some overhead involved just to manage these queues that the service broker has to perform.
I am sure we are not unique with the choice to figure out if we will get a boost in performance using SQL a queue between services rather than a table to queue data. What is available to help understand the performance gains of using a queue?
I'm trying to flesh out a good queue table design with our dev team.So here is a general overview of the scenario. First an application will hit a WebAPI and grab any updates to Content and store those ID's in SQL (queue table). Next is the fun part, different multi threaded apps will process ID's from the queue. One app will make updates to the data in a different SQL DB while the other will update an index (likely Elastic).
Obviously, we don't want multiple threads working on the same items. One strategy could be to use UPDLOCK & READPAST query hints. However, I'm not sure about the reliability or performance of this solution. I just started looking into setting up a service broker but that would be completely unfamiliar territory for me. Also I can see how a broker might work well within the instance but how would that work with the application making updates to Elastic?

When I create a tableadapter to do an insert it added
SELECT EventDate, EventID, org_id, ROMEventID FROM ROMEvents WHERE (ROMEventID = SCOPE_IDENTITY())
at the end. This looks useful to me since it implies that I can access ROMEventID which is the auto-incremented identity field.
How would I reference the variable in my .cs file?
My insert is working as ROMEventsTableAdapter ROMEventInsert = new ROMEventsTableAdapter();
ROMEventInsert.InsertIntoROMEvents(theDate, EventID, org_id);

Hi
I want a functionality such that I want to return a select query resultset and a varchar variable from a procedure. How can I achieve that,and moreover how can I fetch them in ASP??
Waiting for someone to shed a light of hope.
Thanx a lot
Why does this not work?
declare @ret varchar(50)
DECLARE @X SQL_VARIANT
set @X=10
SET @ret=select SQL_VARIANT_PROPERTY(@X,'BaseType')
Just trying to assign the SQL_VARIANT_PROPERTY return value to @ret and it issues an error: Implicit conversion from data type sql_variant to varchar is not allowed. Use the CONVERT function to run this query.
But I don't want to convert I just want to assign the result to the variable.
what's confusding is that you can do this:
if(select SQL_VARIANT_PROPERTY(@X,'BaseType'))='int'
So I assume I should b able to do the above.

Hi all
We are writing a web-based multi-user call centre application application.
we are getting concurrency problems as you would expect with a multiuser application.
the application is made for callers who will bring up a different contact to call based on some predefined priority. now because the algorithm that prioritises the contacts takes a good 2 seconds to run, if 2 different caller request for the next prioritised contact, they will retrieve the same contact.
The only way that we think can resolve this problem is by building a queue. The queue would be implemented as a table, the particular implementation of this queue would be, when ever someone retrieves an entry from the queue, a background process will go on and generate a new queued item, i.e. in a FIFO manner. So that's how we think we should implement the queue.
Now come the question how to implement it. My idea is to have row level locking and a trigger to remove queue items from the queue. so that once one caller have looked at one of the item in the queue, another user can't look at the same item.
Any suggestions as to how i might be able to avoid concurrency problems?
What do you all think of my idea of implementing the FIFO queue?/
Is it possible to do row level locking in such a way that other users won't even be able to read the locked entry??
James :)
hey all you database guru's hopefully someone can lend some insight as to a little table design problem I have.
Basically I've got a system in place to authorize users to access a website typical username password stuff. The table contains a list of users and there passwords plus the auth level and a few other tid bits that aren't really important enough to into detail about them here. What I want to do is add a messaging system to this, I think I could probably figure out a way to do this half decent if I setup a seperate table for each user to add a row to the table for every message entry than in my asp.net code have it delete everything but the last 10 entries every time a user logs on. However I would much prefer a way that I didn't have to setup a whole new table for each user just for messaging purposes, maybe store something like a list in one of the database cell's kind of like .nets generic.list or better yet generic.queue, I would also like a way if it's possible without too much work to have the table automatically delete the oldest message every time a new message is received if there's already 10 messages existing for the user.
Anyways hopefully someone has some experience in setting up a system like this, I don't really require any code samples I can code it all myself (other than the database code to automatically remove entry's, I'm not a database guy) if someone could just explain a way to accomplish what I'm trying to do, or if someone has a different more convenient way of doing this I would be up for suggestions
Thanks in advance for any help offered, I do appreciate it
In a situation where messages are coming in faster than they can be processed, at what point will service broker start up another queue_reader? Also, how do you prevent table locking if part of the processing of that message involves inserting or updating data in a table? We are experiencing this problem because of the high number of messages coming through, and I'm not sure what the best solution is - does service broker have some built-in support for preventing contention on a table when multiple readers are running? Or maybe a pattern that can be used to get around it?

as you can see, im trying to return a comment_count value, but the only way I can do this is by defining the variable.
I have had to do it this way, because I cannot say COUNT(comment.comment_id) AS comment_count or it returns an error that it cant reference the comment.comment_id.
But when change it to FROM article, comment; I get errors about the article_author_id and article_comment_id.
And i cant add a join, because it would return the amount of rows of the comment...
unless someone could help with what i Just decribed (as i would prefer to do it this way), how would i return the variable value as part of the select statement?
Cheers
I have a parent package (i.e. P) and a child package (C). I was able to easily pass a variable value from P to C. And C did computations and get a result (i.e. integer) and stored this integer to a variable (x).
Now I want the value of "x" to be passed back to P and store in P's variable (say Px). Anyone knows how to ?
