Limit The Number Of Records Returned In Stored Procedure.
Aug 17, 2007
In my ASP page, when I select an option from the drop down list, it has to get the records from the database stored procedure. There are around 60,000 records to be fetched. It throws an exception when I select this option. I think the application times out due to the large number of records. Could some tell me how to limit the number of rows to be returned to avoid this problem. Thanks.

I have no problem getting OLE DB Command transformations to support single returns by a procedure.
For example, exec name_of_procedure ?,?,? OUTPUT
However, I have a stored procedure which accepts 1 input and returns 5 outputs. This procedure works fine at the command line but when I try to incorporate it into a OLE DB Command I don't get the multiple values returned. There's no problem at all configuring the transform as it recognizes all input and output parameters. For some reason I just don't get values returned.
I am doing some SELECT queries on my database through ASP, but for example, I only want to return the 50 most recent entries that match the criteria. Is there any easy way to limit the number of results returned?
I have a stored proc that is returning the results I need for output to .txt file.
Is there a way in SSIS to commit 50K (or whatever number) row batches at a time or should I just handle this in the stored proc?
select * into #TempTable from SomeTable [WHILE LOOP] --throttle commit batches of 50K rowcount select * from #TempTable [END LOOP] drop table #TempTable
But If I'm doing this in SSIS, I can't drop the #temp table otherwise I have nothing to output right?
When querying a bit field, I am encountering a problem with MS SQLServer returning a larger number of records for a table than theactual number of records that exist within that table.For example, my customer table has 1 million unique records, so theresults of the following query are as such:select count(customer_nbr) from customer = 1,000,000There is bit field in the customer table that denotes whether acustomer has placed an order with us called. That flag is calledorder_flagIf I run the following query:select count(customer_nbr) from customer where order_flag = 1The result is 3,000,000 records.There is no logical way that this is possible, as my table onlycontains 1,000,000 unique records and the number of customers with anorder should be a subset of this.If a run the above query with a distinct before customer number, I getthe results I want:select count(distinct customer_nbr) from customer where order_flag = 1600,000 records.So while I can get to the answer I want, I have no idea why I amreturning incorrect values if I don't select distinct.Can anyone help? I checked microsoft support and message boards buthaven't seen anything.I should note that the bit field is indexed.I am not sure if that isthe problem or not.
Hi,I'm using c# with a tableadapter to call stored procedures. I'm running into a problem where if I have over a certain byte size or number of parameters being passed into my stored proc I get an exception that reads: "Cannot evaluate expression because a thread is stopped at a point where garbage collection is impossible, possibly because the code is optimized." If I remove one parameter, the problem goes away. Has anyone run into this before? Thanks,Mark
Hi, I use a strong-typed DataSet to build the data access tier of my application, and the IDE generates most of code for me. However I can't find a way to get the value returned by a stored procedure(The stored procedure seems like 'RETURN 0').I noticed that a @RETURN_VALUE parameter is added automatically for each query method, but I don't know how to read the value. Anybody could help me with the problem? Thanks.
I have a store procedure (e.g. sp_FetchOpenItems) in which I would like to call an existing stored procedure (e.g. sp_FetchAnalysts). The stored proc, sp_FetchAnalysts returns a resultset of all analysts in the system. I would like to call sp_FetchAnalysts from within sp_FetchOpenItems and insert the resultset from sp_FetchAnalysts into a local temporary table. Is this possible? Thanks, Kevin
I have an asp.net 1.1 website that uses sql server 2000 and vb.I have a bit of a dilema, when I run a stored procedure in a webpage it returns the wrong value, but if I run itin the query analyzer the correct value is returned. Dim orderHistory As nlb.OrdersDB = New nlb.OrdersDB
' Obtain Order ID from QueryString Dim OrderID As Integer = CInt(Request.Params("ID"))
' Get the customer ID too Dim myNewCustomerId As Integer = 0 myNewCustomerId = orderHistory.GetOrderCustomer(OrderID)
Public Function GetOrderCustomer(ByVal orderID As Integer) As Integer
' Create Instance of Connection and Command Object Dim myConnection As SqlConnection = New SqlConnection(ConfigurationSettings.AppSettings("ConnectionString")) Dim myCommand As SqlCommand = New SqlCommand("nlbsp_OrdersCustomerID", myConnection)
' Mark the Command as a SPROC myCommand.CommandType = CommandType.StoredProcedure
' Add Parameters to SPROC Dim parameterOrderID As New SqlParameter("@order_id", SqlDbType.Int, 4) parameterOrderID.Value = orderID myCommand.Parameters.Add(parameterOrderID)
Dim parameterOrderCustID As New SqlParameter("@customer_id", SqlDbType.Int, 4) parameterOrderCustID.Value = ParameterDirection.Output myCommand.Parameters.Add(parameterOrderCustID)
'Open the connection and execute the Command myConnection.Open() myCommand.ExecuteNonQuery() myConnection.Close()
' Return the customer_id (obtained as out paramter of SPROC)
If parameterOrderCustID.Value <> 0 Then Return CInt(parameterOrderCustID.Value) Else Return 0 End If
End Function
the stored procdure is CREATE PROCEDURE [dbo].[nlbsp_OrdersCustomerID] ( @order_id int, @customer_id int OUTPUT ) AS
/* Return the customer_id from the Orders. */ SELECT @customer_id = customer_id
FROM nlb_Orders
WHERE order_id = @order_id GO
I know a particular order_id returns a value of 1. But when I run it in the webpage it always comes back as 2. Any ideas would be appreciated ThanksPete
The following query only brings back too much data in the table - there are duplicates and the lab it shows is wrong. The problem is: AND a.calLab = f.ID in the Where statement. Some equipment does not need calibration, so, a.calDueDate = 0 AND a.calLab would be NULL or 0. tblLabs ID field has 1 - 18 (Labs) - no 0 and of course no null I need to get the rest of the data. Any suggestions? Thanks..... Zath
SELECT a.assignedID, b.Manufacturer, a.modelNumber, a.serialNumber, e.equipmentType, a.Description, c.Location, d.Status, a.modifiedDate, a.modifiedBy, a.Notes, a.Picture, f.LabName, a.calibrationRequired, a.calDate, a.CalDueDate, a.assetNumber, a.ID FROM tblEquipments a, tblManufacturers b, tblLocation c, tblStatus d, tblEquipment_Type e, tblLabs f WHERE a.manufacturer = b.manufacturerID AND a.location = c.locationID AND a.Status = d.statusID AND a.EquipmentType = e.ID AND (a.calLab = f.ID or a.calLab Is NULL or a.calLab = 0) ORDER BY a.ID
I have a stored procedure that selects * from my table, and it seems to be working fine: USE myDB GO IF OBJECT_ID ( 'dbo.GetAll', 'P') IS NOT NULL DROP PROCEDURE GetAll GO CREATE PROCEDURE GetAll AS DECLARE ref_cur Cursor FOR SELECT * FROM myTable Open ref_cur FETCH NEXT FROM ref_cur DEALLOCATE ref_cur
The problem is, I'm trying to create a DB class, and I'm not sure what Parameter settings I'm supposed to use for my returned values. Can anyone help me finish this?public class dbGet_base { public dbGet_base() { _requestId = 0; }
public dbGet_base(Int64 RequestId) { this._requestId = RequestId; getDbValues(RequestId); } public void getDbValues(Int64 RequestId) { getDbValues(RequestId, "GetAll"); } public void getDbValues(Int64 RequestId, string SP_Name) { using(SqlConnection Conn = new SqlConnection(ConfigurationManager.AppSettings["WSConnection"])) using (SqlCommand Command = new SqlCommand(SP_Name, Conn)) { Command.CommandType = CommandType.StoredProcedure; Command.Parameters.Add("@Request_Id", SqlDbType.Int).Value = RequestId; Command.Parameters.Add(?? } }

I can run it in Query Analyzer and it returns one record as it should. I want it in ASP.NET to return the amount of rows that are effected, e.g that the login is correct.
The code I have is:
public bool ValidateUserIdAndPassword(string userId, string password) { sqlCommand.CommandType = CommandType.StoredProcedure; //the name of the stored procedure sqlCommand.CommandText = "spValidateUserIdAndPassword";
SqlParameter myParam;
//add the param's to the SP
//userId information for the user myParam = new SqlParameter("@UserId", SqlDbType.VarChar, 50); myParam.Value = CStr(userId); sqlCommand.Parameters.Add(myParam);
//password information for the user myParam = new SqlParameter("@Password", SqlDbType.VarChar, 50); myParam.Value = CStr(password); sqlCommand.Parameters.Add(myParam);
I have a stored procedure that return either 1 or -1 : IF EXISTS( ) BEGIN return 1 ENDELSE BEGIN return -1 ENDAnd then I try to retrieve the returned value by doing this:int value = Convert.ToInt32(command.ExecuteScalar());But the value I get is always 0. Anyone see what is wrong?
I have the following stored procedure. The good thing is I finally got the syntax to the point where it doesn't blow up, but I was under the impression the "print" statement would print my result. In this case all I get is the statement ' 1 Row Affected ' which by the way is not the answer I was expecting.
Here's the code: ' CREATE PROCEDURE createevents AS
declare @myvariable varchar(700)
declare @myvar varchar(700)
begin Select @myvariable = d.id from table1 d, table2 dc where d.class = dc.class
If @myvariable > 0 begin Select @myvar =dp. class from table3 dp, table2 dc where dp.class = dc.class
If @myvariable >= 1 begin print @myvariable + (',') + @myvar end end
else begin print @myvariable + ('is empty') end end
Hi,I have a .NET application that I want to save the Config.EXE contentsto my SQL database for remote review/testing. This config file is3700+ bytes long. I created a field in one of my tables with a VARCHAR4800 and then created a stored procedure that receives a parameter(also VARCHAR(4800).However it fails to write anything if the length of the value that Ipass is anything greater than 900. If I pass exactly 900 characters orless - the data is written to the field. If I pass 901 characters Iget nothing.I'm suspicious since it is exactly 900. I seriously doubt it's somelimitation of MS-SQL so I need a nudge in the right direction.Thanks
I am using the following stored procedure to insert a value into the database. I am new to stored procedures so I need help. Basically this stored procedurewill only insert a value for "CustomerName" if it is not a duplicate value. So I noticed in My C# when I call this stored procedure, a negative one "-1"is returned if the insert is not performed because of a duplicate value. Is that correct? Should I be getting back a negative one "-1" ? You seeI thought that a Zero "0" would be returned if the insert was not performed.Not a negative one? SET ANSI_NULLS ONGOSET QUOTED_IDENTIFIER ONGO CREATE PROCEDURE [dbo].[CustomerCreate]( @CustomerDescription nvarchar(100), @CustomerName nvarchar(100), @LastUpdateDate datetime, @LastUpdateUser nvarchar(32), @inserted_record smallint output) AS if exists (select 1 from Customer where CustomerName = @CustomerName) BEGIN set @inserted_record = 0 END ELSE BEGIN INSERT INTO Customer ( CustomerDescription, CustomerName, Active, LastUpdateDate, LastUpdateUser ) VALUES ( @CustomerDescription, @CustomerName, @LastUpdateDate, @LastUpdateUser ) END
I am trying to use a stored procedure inside the scripter in a site server pipeline. Can anyone tell me how the scripter will read the the result which is a variable. The stored procedure is returning the right value when run in query analyzer but I don't know how to retrieve it inside the pipeline.

CREATE PROCEDURE AddUserToLog (@UserID int ) AS INSERT INTO SelectedUsers (UserID,SelectedOn) VALUES (@UserID,getdate()) Can anyone help me to get these working togethsr in the same qurey?
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.
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;
Is there a way to limit the number of rows returned by a SqlDataReader? I know I can do it by modifying the Stored Procedure, but I'd rather not modify a procedure that is used in multiple apps. I'm hoping there is something easy like setting SqlDataReader.RowsReturned = 100, but that might be too easy to hope for.
I have a stored procedure which returns a result set as follows:
(Headers)Total,WV1,WV2,WV3,WV4,WV5..... (Example data) "Some total name",1,2,3,4,5.....
The WV1, WV2, WV3 column names will be different depending on parameters passed to the stored procedure. In other words, the column names or number of columns aren't fixed (apart from "Total").
What I would like to be able to do is to just force SSRS to use the column headers supplied by the stored procedure as the column names in the report.
