SQL Stored Procedure Returns Duplicates
Mar 23, 2007
I am new to SQL and SQL Server world. There must be a simple solution
to this, but I'm not seeing it. I am trying to create a crystal
report (v8.5) using a stored procedure from SQL Server (v2000) in
order to report from two databases and to enable parameters.
When I create the stored procedure, it joins multiple one-to-many
relationship tables. This results in repeated/duplicate records. Is
this an issue that should be solved within the stored procedure, or is
this inevitable? If latter, how do you eliminate the duplicates in
Crystal Reports?
Let's say we have three different tables - Event, Food, Equipment.
Each event may have multiple food and multiple equipments; some events
may not have food and/or equipments. The stored procedure outcome may
look like this:
Event Food Food_Qty Equipment
Equipment_Qty
Event1 Food2 10 Equipment5
1
Event1 Food4 10
NULL NULL
Event2 Food4 50 Equipment2
10
Event2 Food4 50 Equipment5
2
Event2 Food1 12 Equipment2
10
Event2 Food1 12 Equipment5
2
As you can see in Event2, for each Food variations, Equipment values
repeat. When I am creating a Crystal Reports, I have the duplication
problem.
What I would like to see in the report is either:
Event1
Food2, 10 Equipment5, 1
Food4, 10
Event2
Food4, 50 Equipment2, 10
Food1, 12 Equipment5, 2
OR:
Event1
Food2, 10
Food4, 10
Equipment5, 1
Event2
Food4, 50
Food1, 12
Equipment2, 10
Equipment5, 2
Attempt1: Using "Eliminate Duplicate Record" option does not work with
the Equipment section since CR does not recognize "Equipment2" in the
third line of the table and "Equipment2" in the fifth line of the
table as duplicates.
Event1 Food2, 10 Equipment5, 1
Food4, 10
Event2 Food4, 50 Equipment2, 10
Equipment5, 2
Food1, 12 Equipment2, 10
(duplication)
Equipment5, 2
(duplication)
Attempt2: I created group for each category (Event, Food, Equipment),
put the data in Group Headers and used "Suppress Section" to eliminate
if the same equipments are listed more than once within the Food
group. This eliminated the duplication, but the items do not align
correctly.
Event1 Food2, 10 Equipment5, 1
Food4, 10
Event2 Food4, 50 Equipment2, 10
Equipment5, 2
Food1, 12 (I want this to appear right below the
'Food4, 50' line)
I would really appreciate any suggestions! Thank you in advance.

I am trying to create a report in Crystal Reports (v 8.5). I have astored procedure to pull data from two databases and parameters.There are multiple one-to-many relationships and the stored procedurereturns duplicates; e.g., one schedule may have multiple resources,supplies, and/or orders (and one order may have multiple foods). Isthere a way to stop the duplication?The stored procedure looks like this:************************************************** **********************************SET QUOTED_IDENTIFIER OFFGOSET

Hi,I have a stored procedure (the code is below) that I use to retrieveone value from my database. I tested the code in Query Analyzer, and itworks (I get the value I was looking for). However, when I call thesame code from the stored procedure, I get no value. The code that isexecuted is the same and the input parameter is the same. Does anybodyhave an idea?The code:SELECT Top 1CharID,CharName,CategoryName,CharDescription,UserIDFROM [Character]WHERE CharName='Character'-- returns the right valueThe Stored Procedure:CREATE PROCEDURE SpCharacters_SelectOneByUserName@UserName NVarCharASSELECT Top 1CharID,CharName,CategoryName,CharDescription,UserIDFROM CharacterWHERE CharName=@UserNameGO-- returns no value

Hello,I have a stored procedure: -- Get an individual league match by IDALTER PROCEDURE [dbo].[mb_League_GetLeagueMatchByID]( @LeagueMatchID int)ASSET NOCOUNT ONSELECT * FROM mb_LeagueMatch WHERE mb_LeagueMatch.LeagueMatchID = @LeagueMatchIDThe mb_LeagueMatch table has a column named IsActive that is a bit datatype.The value for all rows is set to true (in database explorer in visual studio 2005).When I execute the above stored procedure I always get -1 (I'm guessing that means null) as a result for IsActive if it was true and 0 when false (as expected).However, when I run a query on the database for the same parameter, I get the expected 1 as the value for IsActive.Has anyone seen this before?Thanks,Howard

I have following stored procedure:
-------------
CREATE PROCEDURE dbo.Test
@name as char(36)
as
select a, b
from testtable
where name LIKE @name +'%'
------------
when I run the select statement from query analyzer,
select a, b from testtable where name LIKE 'a%'
it returns records.
But when I call the stored procedure from query analyzer,
exec Test 'a'
it returns no record.
What might be wrong?
Any help is appreciated.

I have a stored procedure
Code Block
CREATE PROCEDURE WEA_SelectEmployeeListByCourseOrProject

@strUserName nvarchar(20)
AS
SET CONCAT_NULL_YIELDS_NULL OFF

AND
( ((@CourseID = 0 AND @blnIsSearch=1 ) OR COALESCE(AssignedEmployee.CourseID,0) = @CourseID))
AND
(@ProjectID = 0 OR COALESCE(AssignedEmployee.ProjectID,0) = @ProjectID)
AND
(
(@strRole = 'MIS_TUTOR' AND

)
OR
(@strRole <> 'MIS_TUTOR')
)
SET CONCAT_NULL_YIELDS_NULL ON
GO
now if i run this stored procedure in Query Analyzer like so...
exec wea_SelectEmployeeListByCourseOrProject 0,0,1,'K_T'
i get 48 records returned.
but if i lift the SQL out of the stored procedure and run it in Query Analyzer like so....
Code Block

OR

)
SET CONCAT_NULL_YIELDS_NULL ON
i only get 5 records returned???
so why do i get a difference when its the same SQL??
Username 'K_T' is of role 'MIS_TUTOR' therefore @Role = 'MIS_TUTOR'
any help on unravelling this mystery is appreciated!

I have a stored procedure on a SQL server, which is workign correctly to check some date/time parameters and then insert a row into a log table.
I am calling it from an ASP page. Initially I just called it and didn't worry about the return value. However the Stored procedure now will return a value to determine if it made the change or not and if not why (ie log entry was at incorrect time etc).
I woudl liek to capture this returned value in my code to display a message to the user but am havign problems finding the right way to get the value.
I am calling the SP as follows:
Shared Sub createlogentry(ByVal ID, ByVal tme, ByVal val) Dim result As String Dim cs As String = ConfigurationManager.ConnectionStrings("connecttion1").ToString Using con As New System.Data.SqlClient.SqlConnection(cs) con.Open() Dim cmd As New System.Data.SqlClient.SqlCommand() cmd.Connection = con cmd.CommandType = Data.CommandType.StoredProcedure cmd.CommandText = "CreateLogEntry" cmd.Parameters.Add("@ChID", Data.SqlDbType.Int) cmd.Parameters("@ChID").Value = ID cmd.Parameters.Add("@Value", Data.SqlDbType.Int) cmd.Parameters("@Value").Value = val result = cmd.ExecuteNonQuery().ToString End Using End Sub
I have tried amending the ExecuteNonQuery line to ExecuteReader()
Any help appreciated
Regards
Clive

Hi !
I have trying to do an insert with a subroutine that calls a stored procedure, but it doesn’ t run. The page loads properly but nothing is inserted in the table of the database, no errors appears after submit the form.
<asp:Button id="SubmitButton" OnClick="Send_data" Text="Submit" runat="server"/>
Here is the code:
Sub Send_data(Sender As Object, E As EventArgs)
Dim CmdInsert As New SqlCommand("new_user1", strConnection)
CmdInsert.CommandType = CommandType.StoredProcedure
Dim InsertForm As New SqlDataAdapter()
InsertForm.InsertCommand = CmdInsert
CmdInsert.Parameters.Add(New SqlParameter("@RETURN_VALUE", SqlDbType.bigint, 8, "User_id"))
CmdInsert.Parameters("@RETURN_VALUE").Direction = ParameterDirection.ReturnValue
CmdInsert.Parameters.Add(New SqlParameter("@e_mail", SqlDbType.varchar, 50, "e_mail"))
CmdInsert.Parameters("@e_mail").Value = mail.Text()
End Sub
What it lacks?

Guys,
could someone please tell me : am I supposed to use the OLE DB
Command in a dataflow to call a stored procedure to return a value? Or
is it just supposed to be used to call a straightforward insert
statement only?
What I am hoping to do:
I have a table with a few columns and one identity column. In a
dataflow I would like to effect an insert of a record to this table and
retrieve the identity value of the inserted record... and I'd like to
store the returned identity in a user variable.
If I AM supposed to be able to do this... then how on earth do I do it?
I have spent hours fooling around with the OLE DB command trying to call a stored proc and get a return value.
In the Advanced Editor any time I try to add an output column (by
clicking on Add Column) I just get an error dialog that says "the
component does not allow adding columns to this input or output)
So, am getting pretty concussed .. banging my head of the wall like this...
So put me out of my misery someone please.... is the OLE DB Command intended for this or not?
Thanks

I have a Column called SaleID in some tables in a Database.The SaleID column has the int datatype. I need a stored procedure that returns the next value in sequence for the SaleID column.
For Example,
If the last value inserted into the SaleID column was 1022 the stored procedure should return 1023
If the last value inserted into the SaleID column was 1023 the stored procedure should return 1024.
If the last value inserted into the SaleID column was 1024 the stored procedure should return 1025.
Also an exclusive lock should be maintained while the the stored procedure is running.
I am using SQL Server 2005.

I have a Gridview bound to a SQLDataSource that uses a Stored Procedure expecting 1 or 2 parameters. The parameters are bound to textbox controls. The SP looks up a person by name, the textboxes are Last Name, First Name. It will handle last name only (ie. pass @ln ='Jones' and @fn=null and you get all the people with last name=Jones. I tested the SP in Management Studio and it works as expected. When I enter a last name in the Last Name textbox and no First Name I get no results. If I enter a Last Name AND First Name I get results. I don't understand.
Here's the HTML View of the page. The only code is to bind the Gridview when the Search button is pressed.

I'm pretty new to .NET and am looking for advice on how to speed up a simple stored procedure that returns 35,000 plus rows. It's a super simple query that returns a client list. It's just that there is soooooo many rows, it's super slow when the page loads.

I have a stored procedure that works when executed in query analyzer. (It is also way too long to post here) When called from my application ado.net returns the error:
Invalid object name #idTable
If I run the proc in query analyzer using the same parameters (copied from quickwatch while debugging) there is no error.
While very complicated, this procedure runs quickly so timing out is not an issue.
Does anyone know why a proc would run in query analyzer and not in an asp.net/c# application?
Thank you.

I have a stored procedure like "select * from ThisTable"
I'm doing a dataread like:
Dim val as String = dateRead("column_from_ThisTable")
If the value in the column is not null everything works great, but if the value is null, instead of getting a value of "" which I expect, I get the column name??? In this case "column_from_ThisTable"
How do I make sure I get "" returned when the value in the column is db.null?

Hi All,
When I use the following I get an error. I think it is because of duplicate records in my table.
Update person
Set username = (Select username
From update_person
Where person.firsname = update_person.firstname
and person.lastname = update_person.lastname)
There are a few users that have the same first and last name. How can I ignore the duplicate records and continue to update the table?
Thanks in advance.

Hi there everyone. I have a stored procedure called “PagingTable� that I use for performing searches and specifying how many results to show per ‘page’ and which page I want to see. This allows me to do my paging on the server-side (the database tier) and only the results that actually get shown on the webpage fly across from my database server to my web server. The code might look something like this:
strSQL = "EXECUTE PagingTable " & _
"@ItemsPerPage = 10, " & _
"@CurrentPage = " & CStr(intCurrentPage) & ", " & _
"@TableName = 'Products', " & _
"@UniqueColumn = 'ItemNumber', " & _
"@Columns = 'ItemNumber, Description, ListPrice, QtyOnHand', " & _
"@WhereClause = '" & strSQLWhere & "'"
The problem is the stored procedure actually returns two result sets. The first result set contains information regarding the total number of results founds, the number of pages and the current page. The second result set contains the data to be shown (the columns specified). In ‘classic’ ASP I did this like this.
'Open the recordset
rsItems.Open strSQL, conn, 0, 1
'Get the values required for drawing the paging table
intCurrentPage = rsItems.Fields("CurrentPage").Value
intTotalPages = rsItems.Fields("TotalPages").Value
intTotalRows = rsItems.Fields("TotalRows").Value
'Advance to the next recordset
Set rsItems = rsItems.NextRecordset
I am trying to do this now in ASP.NET 2.0 using the datasource control and the repeater control. Any idea how I can accomplish two things:
A) Bind the repeater control to the second resultset
B) Build a “pager� of some sort using the values from the first resultset

This SQL is meant to show the changes that will be made, when removing a selected user's email address from a batch.
However, when executed, each row is duplicated, and in the duplication, the semi-colon or comma isn't removed. For example, if I wanted to remove user "sam@mail.com"
The table results displayed would be:
Row 1:
BatchID: 50
ParamName:EmailTo
ParamValue: jack@mail.com;sam@mail.com;frank@mail.com
NewParamValue: jack@mail.com;frank@mail.com
Row 2:
BatchID: 50
ParamName:EmailTo
ParamValue: jack@mail.com;sam@mail.com;john@mail.com
NewParamValue: jack@mail.com;;frank@mail.com
Ideally, it should only display each row once, and not have the semicolon error. It seems to be a union error, because when I comment out the First and second union statements, it runs fine.
-- Delete email address from a.Batch
IF(@EmailAddress IS NOT NULL)
BEGIN
IF(LEN(@EmailAddress) > 0)
BEGIN
IF(@ShowOnly = 1)
[Code] ......

}
same sp working perfectly with SQL Server 2000
am getting a error message
com.microsoft.sqlserver.jdbc.SQLServer
Exception: A server cursor cannot be opened on the given statement or statements
. Use a default result set or client cursor.
If a SP doesnt have a temp table, then there is no issue, SP executes perfectly, but if a SP has a temp table, this error occurs.
SP :

@countrCode varchar(3)
as
select countryname INTO #TMPCOU from country where countryCode = @countrCode
SELECT COUNTRYNAME FROM #TMPCOU

Hi everybody I need help on finding duplicates and deleting the duplicate record depending on name and fname , deleting the duplicates and leaving only the first one.
my PERSON table is this below:
ID name fname ownerid id2
1 a b
2 c c
3 e f
4 a b 1 10
5 c c 2 11
I have this query below that returns records 1 and 4 and 2 and 5 since they have the same name and fname
select * from ( Select name ,fname, count(1) as cnt from PERSON group by
name,Fname ) where cnt > 1
ID name fname ownerid id2
1 a b
4 a b 1 10
2 c c
5 c c 2 11
With this result I need to delete the second record of each group but update the first records with the ownerid and id2 of the second record that would be deleted... I don't know how to proceed with this..

Hi,
I have a procedure that inserts a record to a table and return the @@Identity as an output parameter.
This table has a trigger that is triggered when a record is inserted and add a new record to other table.
The problem is that the @@Identity returned is totally wrong.
Any ideas?
Thanx in advance.

I am using SQL Server 2005 Developer on XP Home.
I have the following in one "New Query" window.
use test_01;
go
create table test_tbl_01 (
fname nvarchar(30),
lname nvarchar(30),
phone nvarchar(30),
another_field nvarchar(30));
go
insert into test_tbl_01 (fname, lname, phone, another_field)
values ('Susan', 'Johnstone', '555-0123', 'Some other data');
insert into test_tbl_01 (fname, lname, phone, another_field)
values ('Steven', 'Stonewall', '555-0124', 'More filler data');
insert into test_tbl_01 (fname, lname, phone, another_field)
values ('Bob', 'Otherguy', '555-0125', 'Just some text');
insert into test_tbl_01 (fname, lname, phone, another_field)
values ('Fred', 'Johnson', '555-6666', 'What ev');
insert into test_tbl_01 (fname, lname, phone, another_field)
values ('Carol', 'Jackson', '555-5432', 'You go girl!');
go
create procedure test_sp_01 @LName nvarchar
as
select *
from test_tbl_01 tt
where tt.lname like @LName + '%';
go
exec test_sp_01 @LName = 'John';
The result is:
Susan Johnstone 555-0123 Some other data
Fred Johnson 555-6666 What ev
Carol Jackson 555-5432 You go girl!
Why does the result include Carol Jackson? I expect that it should only include the two John....
More importantly, how can I get it to inlude only Susan Johnstone and Fred Johnson?
Thanks,
Gregory

I am databinding a dataset formed from a stored procedure,(all done on page_load).
However, the reference to the column name is not recognised with the following error being returned.
Column with name "CalcVal" was not found.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. Exception Details: System.ArgumentException: Column with name "CalcVal" was not found.Source Error:
Line 152: chartCommand.Fill(chartDs);
Line 153: Chart1.DataSource = chartDs;
Line 154: Chart1.DataBind();
Line 155:
Line 156: }
This worked before deployment and the other controls which are bound to data using stored procedures seem to work. However, these other data sources are all sqlDatasoure controls.
Any suggestions would be helpful.
I have found issues relating the to user ID and password which seems to depend on whether the web server and data server are the same machine or whether they are remote from each other.
cheers-jim.

SQL (using 2012) .I'm trying to create some stored procedures that calculate stats needed for item response theory and test scoring (things like reliability, correlation, etc.). I'm writing a procedure that's aimed at splitting a test in half (first half of the items and second half of the items) and calculating each individual (TestID) score for each half. I can insert the first half of the test, but end up getting an error stating that the subquery returned more than one value. I know it's being caused by the group by clause, but if I remove it I end up with a total count of the items answered correctly, but it's necessary for me to link it batch to the TestID (so each row should have a BatchID [same for all at the moment], a unique TestId, a corresponding FirstHalfScore and a corresponding SecondHalfScore for each testID).
Insert into SplitHalfTestScores (BatchId, TestID, FirstHalfScore)
(Select distinct 10001 as BatchId, irt.TestID, count(*) as FirstHalfScore
From irt_TestItems irt where batchID=10001 and ItemId <=40 and TestId = irt.TestId and AnsweredCorrectly = 1 group by TestId)
Update SplitHalfTestScores
Set SecondHalfScore = (Select count(*)
From irt_TestItems irt where BatchId = 10001 and TestId = irt.TestId and irt.ItemId > 40 and AnsweredCorrectly = 1
group by TestId)

I have a table with 22 million Business records. I can see that there are duplicates when I group by BusinessName and Address and Phone. I'd like to place only the duplicates into a table, with a ranking, oldest business key gets a ranking of 1.
As a bonus I'd like each group to have a distinct group name (although not necessary, just want to know how to do this)
Later after I run more verifications to make sure these are not referenced elsewhere I'll delete everything with a matchRank > 1 out of the main Business table.
DROP TABLE [dbo].[TestBusiness];
GO
CREATE TABLE [dbo].[TestBusiness](
[Business_pk] INT IDENTITY(1,1) NOT NULL,
[BusinessName] VARCHAR (200) NOT NULL,
[Address] VARCHAR(MAX) NOT NULL,
[code]....
