From DataSet To SqlDataReader In A CLR Stored Procedure
May 4, 2006
Hi all,
I'm writing a CLR stored procedure that just execute a query using 2 parameters.
SqlContext.Pipe.Send can send a SqlDataReader, but if I've got a DataSet?
How can I obtain a SqlDataReader from a DataSet?
Dim command As New SqlCommand(.......).....Dim ds As New DataSet()Dim adapter As New SqlDataAdapter(command)adapter.Fill(ds, "MyTable")... 'manipulating the ds.Tables("MyTable")
At this moment I have to send the table...but
ds.Tables("MyTable").CreateDataReader()
just give me a DataTableReader, and i can't send it with SqlContext.Pipe.Send(...
I am trying to access data using this code: SqlCommand myCommand = new SqlCommand("myStoredProcedure", myConnection); myCommand.CommandType = CommandType.StoredProcedure; myCommand.Parameters.Add(new SqlParameter("@myID", SqlDbType.Int)); myCommand.Parameters["@myID"].Value = myIDValue; myConnection.Open(); myDataReader = myCommand.ExecuteReader(); myTextBox.Text = myDataReader["myColumn"].ToString(); myDataReader.Close(); myConnection.Close(); I get "data reader has no data" error. A problem with the parameter? The stored procedure returns a row when executed from the database explorer. I have used datasets and table adapters up to now as in the data access tutorial on this site Any Ideas?
Hi All, I'm hoping somebody can help me with this as it is driving me mad. I've created a stored procedure which returns Employee information recordset when the windows username is passed to it as a parameter. I want to then store this information in Session variables so content can be filtered depending on employee status, but when I execute my code no records are returned. I know for a fact that the stored procedure works because I bound it sqldatasource and displayed results from it in a Datalist and tested it in sql server. My code is as follows can anybody see any problems with it, in runs through fine with but when I try a read a field from the datareader in says there is no data to read. Dim CurrentUser As String, Pos1 As Int16, EmployeeId As Int32 Dim cn As New System.Data.SqlClient.SqlConnection Dim param As New System.Data.SqlClient.SqlParameter Dim reader As System.Data.SqlClient.SqlDataReader Dim cmd As New System.Data.SqlClient.SqlCommand
cmd.Parameters.Add(param) reader = cmd.ExecuteReader(CommandBehavior.CloseConnection) EmployeeId = reader.Item("EmployeeID") reader.Close() Any help would be much appricated this is driving me mad. Thank You Shaft
Hello and thank you for taking a moment to read this message. I am simply trying to use a stored procedure to set up a dataset. For some reason when I try to fill the dataset with the data adapter I get the following error: Compiler Error Message: BC30638: Array bounds cannot appear in type specifiers.Line 86: ' Create the Data AdapterLine 87: Dim objadapter As SQLDataAdapter(mycommand2, myconnection2) my code looks as follows for the dataset:<script runat="server">Sub ListSongs() ' Dimension Variables in order to get songs Dim myConnection2 as SQLConnection Dim myCommand2 as SQLCommand Dim intID4 As Integer 'retrieve albumn ID for track listings intID4 = Int32.Parse (Request.QueryString("id")) ' Create Instance of Connection myConnection2 = New SqlConnection( "Server=localhost;uid=jazz***;pwd=**secret**;database=Beatles" ) myConnection2.Open() 'Create Command object Dim mycommand2 AS New SQLCommand( "usp_Retrieve song_",objCon) mycommand2.CommandType = CommandType.StoredProcedure mycommand2.Parameters.Add("@ID", intID4) ' Create the Data Adapter (this is where my code fails, not really sure what to do) Dim objadapter As SQLDataAdapter(mycommand2, myconnection2) 'Use the Fill() method to create and populate a datatable object into a dataset.

I am trying to make a dataset to use with a report. I need to get the data out of a stored procedure. I am using a temporaty table in the stored procedure, and the dataset doesnt recognize any of the colums that are output.
I have the following stored procedure for SQL Server 2000: SELECT a.firstName, a.lastName, a.emailfrom tbluseraccount ainner join tblUserRoles U on u.userid = a.useridand u.roleid = 'projLead' Now, this is not returning anything for my dataset. What needs to be added?Here is the code behind:Dim DS As New DataSetDim sqlAdpt As New SqlDataAdapterDim conn As SqlConnection = New SqlConnection(DBconn.CONN_STRING)Dim Command As SqlCommand = New SqlCommand("myStoredProcdureName", conn)Command.CommandType = CommandType.StoredProcedureCommand.Connection = connsqlAdpt.SelectCommand = CommandsqlAdpt.Fill(DS) Then I should have the dataset, but it's empty.Thanks all,Zath
Hi all, Im still relatively new to SQL Server & ASP.NET and I was wondering if anyone could be of any assistance. I have been googling for hours and getting nowhere. Basically I need to access the query results from the execution of a stored procedure. I am trying to populate a DataSet with the data but I am unsure of how to go about this. This is what I have so far:- 1 SqlDataSource dataSrc2 = new SqlDataSource();2 dataSrc2.ConnectionString = ConfigurationManager.ConnectionStrings[DatabaseConnectionString1].ConnectionString;3 dataSrc2.InsertCommandType = SqlDataSourceCommandType.StoredProcedure;4 dataSrc2.InsertCommand = "reportData";5 6 dataSrc2.InsertParameters.Add("ID", list_IDs.SelectedValue.ToString());7 8 int rowsAffected;9 10 11 try12 {13 rowsAffected = dataSrc2.Insert();14 } As you know this way of executing the query only returns the number of rows affected. I was wondering if there is a way of executing the procedure in a way that returns the data, so I can populate a DataSet with that data. Any help is greatly appreciated. Slainte, Sean
HiI have this code snippet[CODE] string connstring = "server=(local);uid=xxx;pwd=xxx;database=test;"; SqlConnection connection = new SqlConnection(connstring); //SqlCommand cmd = new SqlCommand("getInfo", connection); SqlDataAdapter a = new SqlDataAdapter("getInfo", connection); a.SelectCommand.CommandType = CommandType.StoredProcedure; a.SelectCommand.Parameters.Add("@Count", SqlDbType.Int).Value = id_param; DataSet s = new DataSet(); a.Fill(s); foreach (DataRow dr in s.Tables[0].Rows) { Console.WriteLine(dr[0].ToString()); }[/CODE] When I seperately run the stored procedure getInfo with 2 as parameter, I get the outputBut when I run thsi program, it runs successfully but gives no output Can someone please help me?
I am trying to use a dataset for the first time and I've run into a roadblock early. I added the dataset to the AppCode folder, set the connection string, and selected 'use existing stored procedures' in the configuration wizard. The problem is that there are three input parameters on this procedure and they're not showing up in the 'Set select procedure parameters' box. I went through several of the stored procedures and this is the case for all of them. The weird thing is that if I select the same procedure as an insert procedure then the parameters do show up. Very frustrating, any thoughts? Thanks in advance, N
I'm not sure if anybody else is having a problem with the Return Value of Stored Procedures where you get the "Specified cast not valid" error, but I think I found a "bug" in VS2005 that prevents you from having a return value other than Int64 datatype. I tried to look for the solution for myself on the forums but unfortunately I just couldn't find it. Hopefully, this will help out anyone who had come across the same problem. Basically, I have a stored procedure that I wanted to call as an Update for my ObjectDataSource that returns a Money value. Everytime I do this, I keep getting that error saying "Specified cast not valid" even when I try to change the @RETURN_VALUE data type to Currency or Money. After a long session of eye gouging moments, I decided to look at the code for my dataset. There, I noticed that the ScalarCallRetval for my StoredProcedure query was still set to System.Int64. I changed it to System.Object and, like a miracle, everything works like its suppose to. Ex. protected void SomeObjectDataSource_Updated(object sender, ObjectDataSourceStatusEventArgs e) {GrandTotalLabel.Text = ((decimal)e.ReturnValue).ToString("C"); }
The following is NOT filling the dataset or rather, 0 rows returned.....The sp.....CREATE PROCEDURE dbo.Comms @email NVARCHAR ,@num INT OUTPUT ,@userEmail NVARCHAR OUTPUT ASBEGIN DECLARE @errCode INT SELECT fldNum, fldUserEmailFROM tblCommsWHERE fldUserEmail = @email SET @errCode = 0 RETURN @errCode HANDLE_APPERR: SET @errCode = 1 RETURN @errCodeENDGOAnd the code to connect to the sp - some parameters have been removed for easier read..... Dim errCode As Integer Dim conn = dbconn.GetConnection() Dim sqlAdpt As New SqlDataAdapter Dim DS As New DataSet Dim command As SqlCommand = New SqlCommand("Comms", conn) command.Parameters.Add("@email", Trim(sEmail)) command.CommandType = CommandType.StoredProcedure command.Connection = conn sqlAdpt.SelectCommand = command Dim pNum As SqlParameter = command.Parameters.Add("@num", SqlDbType.Int) pNum.Direction = ParameterDirection.Output Dim pUserEmail As SqlParameter = command.Parameters.Add("@userEmail", SqlDbType.NVarChar) pUserEmail.Size = 256 pUserEmail.Direction = ParameterDirection.Output sqlAdpt.Fill(DS) Return DS Like I said, a lot of parameters have been removed for easier read.And it is not filling the dataset or rather I get a count of 1 back and that's not right.I am binding the DS to a datagrid this way.... Dim DScomm As New DataSet DScomm = getPts.getBabComm(sEmail) dgBabComm.DataSource = DScomm.Tables(0) And tried to count the rows DScomm.Tables(0).Rows.Count and it = 0Suggestions?Thanks all,Zath
Hi, Can anyone please help me solve this problem. My functions works well with this stored procedure: CREATE PROCEDURE proc_curCourseID@studentID int ASSELECT * FROM StudentCourse WHERE mark IS NULL AND studentID = @studentID AND archived IS NULLGO But when I applied the same function to the following stored procedure CREATE PROCEDURE proc_memberDetails@memberID int ASSELECT * FROM member WHERE id = @memberIDGO I received this message Exception Details: System.Data.SqlClient.SqlException: Procedure or function proc_memberDetails has too many arguments specified.Source Error:
Line 33: SqlDataAdapter sqlDA = new SqlDataAdapter(); Line 34: sqlDA.SelectCommand = sqlComm; Line 35: sqlDA.Fill(dataSet); Line 36: Line 37: return dataSet; The function I am using is returning a DataSet as below: public DataSet ExecuteStoredProcSelect (string sqlProcedure, ArrayList paramName, ArrayList paramValue) { DataSet dataSet = new DataSet(); SqlConnection sqlConnect = new SqlConnection(GetDBConnectionString()); SqlCommand sqlComm = new SqlCommand (sqlProcedure, sqlConnect); sqlComm.CommandType = CommandType.StoredProcedure;
for (int n=0; n<paramName.Count; n++) { sqlComm.Parameters.Add(paramName[n].ToString(),Convert.ToInt32(paramValue[n])); }
SqlDataAdapter sqlDA = new SqlDataAdapter(); sqlDA.SelectCommand = sqlComm; sqlDA.Fill(dataSet); return dataSet; } If this is not the correct way, is there any other way to write a function to return a dataset as the result of the stored procedure? Thanks.
I have a great deal of experience in Intrebase Stored Procedures, and there I had the FOR SELECT statement to loop through a recordset, and return the records I wish (or to make any other calculations in the loop). I'm new in MS SQL Stored Procedures, and I try to achieve the same if possible. Below is a Stored Procedure written for MS SQL, which returns me a calculated field for every record from a table, but it places different values in the calculated field. Everything is working fine, except that I receive back as many datasets as many records I have in the Guests table. I would like to get back the same info, but in one dataset:
ALTER PROCEDURE dbo.GetVal AS
Declare @fname varchar(50) Declare @lname varchar(50) Declare @grname varchar(100) Declare @isgroup int Declare @id int Declare @ListName varchar(200)
DECLARE guests_cursor CURSOR FOR SELECT id, fname, lname, grname, b_isgroup FROM guests
OPEN guests_cursor
-- Perform the first fetch. FETCH NEXT FROM guests_cursor into @id, @fname, @lname, @grname, @isgroup
-- Check @@FETCH_STATUS to see if there are any more rows to fetch. WHILE @@FETCH_STATUS =0 BEGIN if (@isgroup=1) Select @grname+'('+@lname+', '+@fname+')' as ListName else Select @lname+', '+@fname as ListName -- This is executed as long as the previous fetch succeeds. FETCH NEXT FROM guests_cursor into @id, @fname, @lname, @grname, @isgroup
I have a big SQL Stored Procedure which works with a cursor inside of it. During the procedure the data is inserted into a table and at the end is a SELECT statement from that table. The problem is that when i create a dataset with that stored procedure and i run it in the Data tab i get the correct select, but in the Fields section of the Report I don't get the fields from the last SELECT, but the fields from the cursor. Am I doing something wrong or is this a bug and how can i fix it. Thanks!
Is it possible to use an Oracle Stored Procedure for an RDLC report. There are posts I've read that deal with RDL reports that use the data tab and command type of "Stored Procedure", but I don't have that installed. I just create a new dataset that the report uses. I can do reports just fine with SQL statements, but I want to be able to call a stored procedure...
Is it possible to combine a stored procedure result set and a table into one dataset? For example, if I have a stored procedure with field "TradeID", and a table with "TradeID", can I join the them in a dataset?
I have a SP that return a dataset and I was thinking to execute that SP inside of other SP then catch the dataset to put into a variable or put into a temp table. What I know is you can not use recordset on output and input parameter in SP correct me if im wrong. I'm just wondering if I there is a work around in this scenario.
I have 4 sets of select queries under 1 stored proc, now on the report calling the stored proc via dataset. when i run the dataset the only first set of the select query related fields appearing under the dataset.
But on the back end sql server, if i execute the same stored proc, i get 4 resultsets in one single executioln.
i am not seeing the remaingin 3 resultsets, on the reports dataset.
Is it possible on the reports or not.
In the asp.net project i was able to use that kind of stored procedures whcih has multiple select statements in 1 procedure., i use to refer 0,1,2,3 tables under a dataset.
I have a procedure where I am inserting some elements into #Table and then finally get the datset I need. Now when I am using this procedure as dataset to my report, it throws up the following error:
Invalid object Name "#TEMP2".
The data that I retrieve is similar to the data that I get from this query in the post by Manivannan.D.Sekaran http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=1871478&SiteID=1
Is it because my columns are generated on the fly that I am not able to retrieve the column headers appropriately. If so can someone suggest a way over to this?
I am not sure should I posting it here or in T-SQL Forum.
ALTER PROCEDURE [dbo].[ReportChart]@Num int,@patID char(16) ASbegin if @Num=2 Begin select * from table1 where patientid=@patID End else If @Num=1 Begin select * from table2 where patientid=@patID End end
While using the above stored procedure, when i bind it with Dataset. The fields corresponding to table1 are displayed in the Fields Tab of the Dataset whereas the Fields corresponding to table2 are not displayed. Please help me out . Thanks In Advance Regards Navdeep

I have a stored procedure that works in my dataset editor, but when i try to run the report, only the "amount" field shows up. Everything else is blank. why is this happening. Here is the stored procedure.
Help! I'm very tired (and new at this) and have looked for a solution in many places. I have an Employee table with a one to many Revenue table. All revenue types are in this table. I need the goals and actuals (two different revenue types) for a datagrid.
This is the result. Because I am looking at two revenue types, the result is providing 2 rows of data instead of one. what is the best way to combine this.

We are facing an issue while executing a stored procedure which uses a table of current database with INNER JOIN a table of another database in same instance.
Per our requirement, we are inserting select statement output in table variable. Then applying business logic and finally showing the data from table variable.
This scenario is working exactly fine in Dev environment. But when we deployed the code in quality environment. Stored procedure does not returning OUTPUT/ (No column names) from table variable.
During initial investigation, we found that collation of these two databases are different but we added DATABASE_DEFAULT collation in the JOIN.
We are collecting values in a string format with delimeteres and sending to DB .We would like to insert the data in Bulk insert format rather than splitting the same and then inserting..
In sql 2014 can we archive the same..sample format currently we are getting the client is like this is
Saleid$ salename$month$year$totalsale#Saleid$salename$month$year$totalsale# has a dataset.
Hi all - I'm trying to optimized my stored procedures to be a bit easier to maintain, and am sure this is possible, not am very unclear on the syntax to doing this correctly. For example, I have a simple stored procedure that takes a string as a parameter, and returns its resolved index that corresponds to a record in my database. ie exec dbo.DeriveStatusID 'Created' returns an int value as 1 (performed by "SELECT statusID FROM statusList WHERE statusName= 'Created') but I also have a second stored procedure that needs to make reference to this procedure first, in order to resolve an id - ie: exec dbo.AddProduct_Insert 'widget1' which currently performs:SET @statusID = (SELECT statusID FROM statusList WHERE statusName='Created')INSERT INTO Products (productname, statusID) VALUES (''widget1', @statusID) I want to simply the insert to perform (in one sproc): SET @statusID = EXEC deriveStatusID ('Created')INSERT INTO Products (productname, statusID) VALUES (''widget1', @statusID) This works fine if I call this stored procedure in code first, then pass it to the second stored procedure, but NOT if it is reference in the second stored procedure directly (I end up with an empty value for @statusID in this example). My actual "Insert" stored procedures are far more complicated, but I am working towards lightening the business logic in my application ( it shouldn't have to pre-vet the data prior to executing a valid insert). Hopefully this makes some sense - it doesn't seem right to me that this is impossible, and am fairly sure I'm just missing some simple syntax - can anyone assist?

More Information for you to know: I have the "ssmsExpressDB" database in the Database Expolorer of VB 2005 Express. But I do not know how to get the SqlConnection and the SqlDataAdapter into the Form1. I do not know how to get the Fill Method implemented properly. I try to learn "Working with SELECT Statement in a Stored Procedure" for printing the 6 rows that are selected - they are not parameterized.
I have written a SQL Procedure to return all the results from a table and am writing a function to run the procedure (So that it is easier to use within my app). I have kinda got a bit confused. :oS
The SQL procedure Gallery_GetAllCetegoryPictures has one input variable (CategoryID) and returns a table procedure is something like SELECT * FROM Gallery WHERE CategoryID = @CategoryID.
The code im having trouble with is below:
Function GetAllCategoryPictures(ByVal CatID As Integer) As DataSet Dim MyConnection As SqlConnection Dim MyCommand As New SqlCommand Dim MyParameter As SqlParameter MyConnection = New SqlConnection(AppSettings("DSN")) MyConnection.Open()
I have some code that I need to run every quarter. I have many that are similar to this one so I wanted to input two parameters rather than searching and replacing the values. I have another stored procedure that's executed from this one that I will also parameter-ize. The problem I'm having is in embedding a parameter in the name of the called procedure (exec statement at the end of the code). I tried it as I'm showing and it errored. I tried googling but I couldn't find anything related to this. Maybe I just don't have the right keywords. what is the syntax?
