Data Binding To A Stored Procedure That Returns Two Result Sets
Mar 6, 2007
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

Hi,
we are facing problem in executing a stored procedure from Java Session Bean,
coding is below.
pst = con.prepareStatement("EXEC testProcedure ?", ResultSet.TYPE_SCROLL_INSENSITIVE, ResultSet.CONCUR_READ_ONLY);
pst.setString(1, "IN");
//
rs = pst.executeQuery();
rs.last();
System.out.println(" Row Number "+rs.getRow());
rs.beforeFirst();
while(rs.next())
{
System.out.println(" Procedure is "+rs.getString(1));
}
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 :
create proc testProcedure
@countrCode varchar(3)
as
select countryname INTO #TMPCOU from country where countryCode = @countrCode
SELECT COUNTRYNAME FROM #TMPCOU
Its really very urgent. Please help me...!

I have a stored procedure like the following. This returns 2 result sets, however i only want it to return 2nd (SELECT SomeField FROM SomeTable). How is this done? Note - it is not possible to change 'SomeSPThatReturnsAnIntAndAResultSet '
CREATE PROCEDURE [dbo].[SomeSP]
@SomeParam int
AS
BEGIN
SET NOCOUNT ON;
declare @SomeScalar int
exec @SomeScalar = SomeSPThatReturnsAnIntAndAResultSet @SomeParam
if @SomeScalar = 0
BEGIN
SELECT SomeField FROM SomeTable
END
END

Greetings
I have a SQL Server stored procedure that performs several queries and therefore returns several "result sets" at any one time.
Wiring it up via ADO.NET I populate a DataSet with a number of items in the Tables collection - which is great - and I can give each item a name for identification purposes once the DataSet is populated.
But I'd like to know if there is some way I can set the names of each result set *within the text of the stored procedure*, i.e. before the DataSet gets populated.
Any help greatly appreciated.

I have a novice question. How does one suppress result sets returned from a stored procedure?
I have created a procedure which makes use of multiple stored procedures . The purpose of this procedure (lets call it procA), is to count the rows returned from other procedures. The €œOther€? procedures will return rows having an unknown number of columns. I would like to limit any changes which may be needed to be made to the €œOther€? procs.
Once procA has collected all of the information (@@rowcount) from the inner procedures, then it will return a result set having several columns €“ mainly the subProcedure name and number of rows returned.
The purpose of procA is to query several subsystems and identify which ones need attention.
Cursor While Loop
exec @ProcName @ObjectName,@userID,@syncDate
set @recs = @@rowcount;
My c# program calls the sp as follows:
cmd = DataUtility.GetSQLCommand();
cmd.CommandType = CommandType.StoredProcedure;
cmd.CommandText = "FetchAdminData";
cmd.Parameters.AddWithValue("@userID", userAlias);
cmd.Parameters.AddWithValue("@adminDate",userDate);
reader = cmd.ExecuteReader();
I do not wish to iterate over each resultSet when I am only interested in the last one. Any suggestions?

Hi all,
I want to know how to handle multiple result sets return from Stored Procedure? I know one way is to insert the result sets into the table, but the limitation is the result sets must have the same data structure. If the result sets have different data structure, how can I handle it.
Thanks,

I hvae a stored procedure that has this at the end of it:
BEGIN
EXEC @ActionID = ActionInsert '', @PackageID, @AnotherID, 0, ''
END
SET NOCOUNT OFF
SELECT Something
FROM Something
Joins…..
Where Something = Something
now, ActionInsert returns a Value, and has a SELECT @ActionID at the end of the stored procedure.
What's happening, if that 2nd line that I pasted gets called, 2 result sets are being returned. How can I modify this SToredProcedure to stop returning the result set from ActionINsert?

I have a stored procedure
Code Block
CREATE PROCEDURE WEA_SelectEmployeeListByCourseOrProject
@ProjectID int,
@CourseID int,
@blnIsSearch int,
@strUserName nvarchar(20)
AS
SET CONCAT_NULL_YIELDS_NULL OFF
DECLARE @strRole nvarchar(15),
@ContactID int
SELECT @strRole = Role, @ContactID = ContactID FROM Contact WHERE UserName = @strUserName
Select DISTINCT Contact.ContactID ID, UPPER(Surname + 'gd ' + Forename ) AS Description, UPPER(Surname + ' ' + Forename + ' ' + ContactReference) AS Description_CR
, UPPER(ISNULL(ContactReference,'')) ContactReference
FROM Contact
LEFT JOIN AssignedEmployee on Contact.ContactID = AssignedEmployee.ContactID
WHERE RUEmployee=1
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
(AssignedEmployee.ContactID = @ContactID
OR CourseID IN (SELECT CourseID FROM AssignedEmployee WHERE ContactID = @ContactID AND Lead = 1)
OR AssignedEmployee.ProjectID IN (SELECT ProjectID FROM AssignedEmployee WHERE CourseID IS NULL AND Lead = 1 AND ContactID = @ContactID))
)
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
SET CONCAT_NULL_YIELDS_NULL OFF
DECLARE @ProjectID int,
@CourseID int,
@blnIsSearch int,
@strUserName nvarchar(20)
SET @ProjectID = 0
SET @CourseID = 0
SET @blnIsSearch = 1
SET @strUserName = 'K_T'
DECLARE @Role nvarchar(15),
@ContactID int
SELECT @Role = Role, @ContactID = ContactID FROM Contact WHERE UserName = @strUserName
PRINT @ContactID
Select DISTINCT Contact.ContactID ID, UPPER(Surname + ' ' + Forename ) AS Description, UPPER(Surname + ' ' + Forename + ' ' + ContactReference) AS Description_CR
, UPPER(ISNULL(ContactReference,'')) ContactReference
FROM Contact
LEFT JOIN AssignedEmployee on Contact.ContactID = AssignedEmployee.ContactID
WHERE RUEmployee=1
AND
( ((@CourseID = 0 AND @blnIsSearch=1 ) OR COALESCE(AssignedEmployee.CourseID,0) = @CourseID)) -- the above line was modified to make sure only employees explicitly assigned to a project are brought back. unless it's a search
AND
(@ProjectID = 0 OR COALESCE(AssignedEmployee.ProjectID,0) = @ProjectID)
AND
(
(@Role = 'MIS_TUTOR'
AND ( (AssignedEmployee.ContactID = @ContactID OR CourseID IN (SELECT CourseID FROM AssignedEmployee WHERE ContactID = @ContactID AND Lead = 1)))
OR
AssignedEmployee.ProjectID IN (SELECT ProjectID FROM AssignedEmployee WHERE CourseID IS NULL AND Lead = 1 AND ContactID = @ContactID)
)
OR
(@Role <> 'MIS_TUTOR')
)
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!
Cheers,
Craig

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.

/*Subject: How to build a procedure that returns differentnumbers of columns as a result based on a parameter.You can copy/paste this whole post in SQL Query Analyzeror Management Studio and run it once you've made surethere is no harmful code.Currently we have several stored procedures which finalresult is a select with several joins that returns manycolumns (150 in one case, maybe around 50 the average).We have analyzed our application and found out that mostof the time not all the columns are used. We haveidentified 3 different sets of columns needed indifferent parts of the application.Let's identify and name these sets as:1- simple set, return the employee list for example2- common set, return the employee information (whichinclude the simple set)3- extended set, return the employee information (whichinlude the common set which itself includes the simpleset) + additional information from other tables, maybeeven some SUM aggregates and so on (I don't know forexample, how much sales the employee did so far).So the bigger sets contain the smaller ones. Please keepreading all the way to the bottom to better understandtechnically what we are trying.Here is a code sample of how our current procedureswork. Please note that the passing parameter we can eitherpass a Unique Identifier (PK) to retrieve a single record,or if we pass for example -1 or NULL we retrieve all theemployee records.*/create table a ( apk int primary key, af1 int, af2 int, af3 int, af4int, af5 int, af6 int)create table b ( bpk int primary key, bf1 int, bf2 int, bf3 int, bf4int, bf5 int, bf6 int)create table c ( cpk int primary key, cf1 int, cf2 int, cf3 int, cf4int, cf5 int, cf6 int)create table d ( dpk int primary key, df1 int, df2 int, df3 int, df4int, df5 int, df6 int)insert a values (1,1111,1112,1113,1114,1115,1116)insert a values (2,1211,1212,1213,1214,1215,1216)insert a values (3,1311,1312,1313,1314,1315,1316)insert a values (4,1411,1412,1413,1431,1415,1416)insert a values (5,1511,1512,1513,1514,1515,1516)insert a values (6,1611,1612,1613,1614,1615,1616)insert b values (1,2111,2112,2113,2114,2115,2116)insert b values (2,2211,2212,2213,2214,2215,2216)insert b values (3,2311,2312,2313,2314,2315,2316)insert b values (4,2411,2412,2413,2431,2415,2416)insert b values (5,2511,2512,2513,2514,2515,2516)insert b values (6,2611,2612,2613,2614,2615,2616)insert c values (1,3111,3112,3113,3114,3115,3116)insert c values (2,3211,3212,3213,3214,3215,3216)insert c values (3,3311,3312,3313,3314,3315,3316)insert c values (4,3411,3412,3413,3431,3415,3416)insert c values (5,3511,3512,3513,3514,3515,3516)insert c values (6,3611,3612,3613,3614,3615,3616)insert d values (1,4111,4112,4113,4114,4115,4116)insert d values (2,4211,4212,4213,4214,4215,4216)insert d values (3,4311,4312,4313,4314,4315,4316)insert d values (4,4411,4412,4413,4431,4415,4416)insert d values (5,4511,4512,4513,4514,4515,4516)insert d values (6,4611,4612,4613,4614,4615,4616)gocreate procedure original_proc @pk int asif @pk = -1set @pk = nullselecta.af1, a.af2, a.af3, a.af4, b.bf1, b.bf2, b.bf3, b.bf4, c.cf1, c.cf2,c.cf3, c.cf4, d.df1, d.df2, d.df3, d.df4fromajoin b on a.apk = b.bpkjoin c on b.bpk = c.cpkjoin d on c.cpk = d.dpkwherea.apk = ISNULL(@pk, a.apk)goexec original_proc 1go/*Currently the above SP is a single SP that is basicallyreturning ALL possible needed data.

I have a UI which supplies 16 parameters to my stored procedure , which in turn call another sored procedure on as400 which returns result set. So far i am able to send 16 parms and get the values in dataset.
My question here how would i send the result set to UI for display, please feel free to comment on any changes need to be made on code . I badly need to find a solution for this and i appreciate any feed backs
Thanks

I have a strange problem with an OleDB call to a stored procedure thatreturns a rowset.Only the first time I execute the query, after I restart SqlServer, myprogram crashes becausethe rowset is empty. All next calls (after restarting my program, ofcourse) run successfully.The context is:1) if I do not bind the output rowset, my program doesn't crash2) If I run the call without the binding and then I run the call withthe binding, it doesn't crash3) It is not the first query I do in my session4) the call crashes only if in the SP there are some inserts: it is awell known problem with OleDB, but in manyother cases I have fixed it setting NOCOUNT to ON

Hi all,
I have some problem about bind field from stored procedure to report.
Now I have dataset that come form stored procedure. In Dataset Dialog, "Fields" tab, I add Fieldname like fieldname in stored procedure. And "Parameters" tab, I add parameters those are neccessary for my stored procedure.
I test on data tab view. When I click "!" to run, then there is input dialog parameter.
I filled it, then the result is ok.
But when I build project, I noticed warning message....
[rsMissingFieldInDataSet] The data set €˜MyDataSet€™ contains a definition for the Field €˜MyField€™. This field is missing from the returned result set from the data source. c:.....visual studio 2005projects

After I build my project, I run the report, each textbox that binded field, display empty value.
What happen with my report? And how can I solve this problem?

Hi all;
How can I show the Name & Age of the selected student's ID in the appropriate TextBox(s) (txtName & txtAge)?
BTW:
My "ShowStudent" stored procedure:
ALTER PROCEDURE ShowStudent
@ID int
AS
SELECT ID, Name, Age FROM Student WHERE ID=@ID
RETURN
And this is the code for "Show" button:
' Which SP? Connection?
Dim cmdSelect As New SqlCommand("ShowStudent", con)
cmdSelect.CommandType = CommandType.StoredProcedure
'-----[ Spacifay SP parameters ]-----
'ID
cmdSelect.Parameters.Add("@ID", SqlDbType.Int, 4)
cmdSelect.Parameters("@ID").Value = CType(txtID.Text, Integer)
'Open Connection
con.Open()
'-----[ Execute the select command ]-----
cmdSelect.ExecuteReader()
'----------------------------------------
'Close connection
con.Close()
'========================================================
End Sub
So, do I have to use an OUTPUT parameter in the stored procedure? If Yes, How to get its (the parameter) value and bind it to the appropriate TextBox?
Hope my question is clear!!
Thanks in advanced!

Since RDMBS and its language SQL is set-based would it make more senseto call a given stored process "Stored Sets" instead of currenttheorically misleading Stored Procedure, as a measure to prodprogrammers to think along the line of sets instead of procedure?

If you write a stored procedure to "SELECT MAX" from a table and the answer is null since the table is empty, how is the null answer returned to the program from the stored procedure? Do you actually get the letters "NULL" or do you just get a space? How should you define your variable in your program?
Thanks in advance!

VS.NET 2005 automatically deploys a CLR stored procedure when you start a project with debugging. However, if the CLR stored procedure attempts to access external resources you will get a message stating:
System.Security.SecurityException: Request for the permission of type 'System.Data.SqlClient.SqlClientPermission, System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.
I've isolated this to being because the CLR stored procedure does not have the EXTERNAL_ACCESS permission set.
Is there a security attribute that can be used to decorate the CLR stored procedure code so that VS.NET 2005 will register the CLR stored procedure with the correct permission set?

My task is to add income by taking few variables from webpage. I had take User ID(From database), Field value by selecting it from DropDownBox( Which value is once again taken from database), Income Description, Date, Amount . I had completed this task successfully by binding DropDownBox to database by query string and added income using stored procedure as below.
I need this to be done using only single Stored Procedure for binding Field Value to DropDownBox and for adding income. Plz tell me how to do this?
ASPX.CS file
protected void Page_Load(object sender, EventArgs e)
{
SqlConnection con = null;
con = DataBaseConnection.GetConnection();
DataSet ds = new DataSet();
SqlDataAdapter da = new SqlDataAdapter("select PA_IFName from PA_IncomeFields where PA_UID=@PA_UID", con);
da.SelectCommand.Parameters.Add("@PA_UID", SqlDbType.Int).Value = (int)Session["PA_UID"];
da.Fill(ds);
IFDdl.DataSource = ds;
IFDdl.DataTextField= ds.Tables[0].Columns[0].ToString();
IFDdl.DataValueField = ds.Tables[0].Columns[0].ToString();
IFDdl.DataBind();
}

IFLabelMsg.Text = "Income Added Successfully!";
} // end of try
catch (Exception ex)

I have a report based on our product names that consists of two parts.Both insert data into a temporary table.1. A single grouped set of results based on all products2. Multiple tables based on individual product names.I am getting data by calling the same stored procedure multipletimes... for the single set of data I use "product like '%'"To get the data for individual products, I am using a cursor to parsethe product list.It's working great except that I have no idea how to identify theresults short of including a column with the product name. While thatis fine, I'm wondering if there is something that is like a header ortitle that I could insert prior to generating the data that would looka little tighter.Thanks in advance-DanielleJoin Bytes!

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

I am calling stored procedure called GetCommonItemCount within another stored procedure called CheckBoxAvailability, the first stored procedure should return a count to second stored procedure and based on that some logic will be executed.
I have 2 problems in that
1. The result is not coming from first stored so the variable called @Cnt is always 0 although it should be 18
2. At the end i need to see in the output the result from second stored procedure only while now i am seeing multiple results of record sets coming.
I have attached the scripts also, the line i described in step1 is

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.

Hi,
I need to know whether a stored procedure returns only a single record or it can return more than one if the query if for example to return all records in a specific date range.

I am new to SQL and SQL Server world. There must be a simple solutionto this, but I'm not seeing it. I am trying to create a crystalreport (v8.5) using a stored procedure from SQL Server (v2000) inorder to report from two databases and to enable parameters.When I create the stored procedure, it joins multiple one-to-manyrelationship tables. This results in repeated/duplicate records. Isthis an issue that should be solved within the stored procedure, or isthis inevitable? If latter, how do you eliminate the duplicates inCrystal Reports?Let's say we have three different tables - Event, Food, Equipment.Each event may have multiple food and multiple equipments; some eventsmay not have food and/or equipments. The stored procedure outcome maylook like this:Event Food Food_Qty EquipmentEquipment_QtyEvent1 Food2 10 Equipment51Event1 Food4 10NULL NULLEvent2 Food4 50 Equipment210Event2 Food4 50 Equipment52Event2 Food1 12 Equipment210Event2 Food1 12 Equipment52As you can see in Event2, for each Food variations, Equipment valuesrepeat. When I am creating a Crystal Reports, I have the duplicationproblem.What I would like to see in the report is either:Event1Food2, 10 Equipment5, 1Food4, 10Event2Food4, 50 Equipment2, 10Food1, 12 Equipment5, 2OR:Event1Food2, 10Food4, 10Equipment5, 1Event2Food4, 50Food1, 12Equipment2, 10Equipment5, 2Attempt1: Using "Eliminate Duplicate Record" option does not work withthe Equipment section since CR does not recognize "Equipment2" in thethird line of the table and "Equipment2" in the fifth line of thetable as duplicates.Event1 Food2, 10 Equipment5, 1Food4, 10Event2 Food4, 50 Equipment2, 10Equipment5, 2Food1, 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 eliminateif the same equipments are listed more than once within the Foodgroup. This eliminated the duplication, but the items do not aligncorrectly.Event1 Food2, 10 Equipment5, 1Food4, 10Event2 Food4, 50 Equipment2, 10Equipment5, 2Food1, 12 (I want this to appear right below the'Food4, 50' line)I would really appreciate any suggestions! Thank you in advance.
