Error: There Is Already An Open DataReader Associated With This Command
Nov 1, 2006
Hi
I'm trying to loop through all the records in a recordset and perform a database update within the loop. The problem is that you can't have more than one datareader open at the same time. How should I be doing this?
cmdPhoto = New SqlCommand("select AuthorityID,AuthorityName,PREF From qryStaffSearch where AuthorityType='User' Order by AuthorityName", conWhitt)
conWhitt.Open()
dtrPhoto = cmdPhoto.ExecuteReader
While dtrPhoto.Read()
If Not File.Exists("D:WhittNetLiveWebimagesstaffphotospat_images_resize" & dtrPhoto("PRef") & ".jpg") Then
cmdUpdate = New SqlCommand("Update tblAuthority Set NoPhoto = 1 Where AuthorityID =" & dtrPhoto("AuthorityID"), conWhitt)
cmdUpdate.ExecuteNonQuery()
End If
End While
This is my code:1 If Session("ctr") = False Then 2 3 Connect() 4 5 SQL = "SELECT * FROM counter" 6 SQL = SQL & " WHERE ipaddress='" & Request.ServerVariables("REMOTE_ADDR") & "'" 7 dbRead() 8 9 If dbReader.HasRows = True Then 10 11 dbReader.Read() 12 hits = dbReader("hits") 13 hits = hits + 1 14 dbClose() 15 16 SQL = "UPDATE counter SET hits=" & hits 17 SQL = SQL & " WHERE ipaddress='" & Request.ServerVariables("REMOTE_ADDR") & "'" 18 dbExecute() 19 20 Else 21 22 SQL = "INSERT INTO counter(ipaddress,hits)" 23 SQL = SQL & " VALUES('" & Request.ServerVariables("REMOTE_ADDR") & "',1)" 24 dbExecute() 25 26 End If 27 28 Session("ctr") = True 29 30 End If 1 Public Sub Connect() 2 Conn = New SqlConnection("Initial Catalog=NURSETEST;User Id=sa;Password=sa;Data Source=KSNCRUZ") 3 If Conn.State = ConnectionState.Open Then 4 Conn.Close() 5 End If 6 Conn.Open() 7 End Sub 8 9 Public Sub Close() 10 Conn.Close() 11 Conn = Nothing 12 End Sub 13 14 Public Sub dbExecute() 15 dbCommand = New SqlCommand(SQL, Conn) 16 dbCommand.ExecuteNonQuery() 17 End Sub 18 19 Public Sub dbRead() 20 dbCommand = New SqlCommand(SQL, Conn) 21 dbReader = dbCommand.ExecuteReader 22 End Sub 23 24 Public Sub dbClose() 25 SQL = "" 26 dbReader.Close() 27 End Sub
I have gathered from reading online that I need to create a 2nd connection to SQL Server if I want to insert records into the database while in a "while (reader.Read())" loop.
I am trying to make my code as generic as possible, and I don't want to have to re-input the connection string at this point in my code. Is there a way to generate a new connection based on the existing open one? Or should I just create 2 connections up front and carry them around with me like I do for the 1 connection now?

it was instantiated once in aspx.cs code.I invoke liuyan(string id,string sign) twice.The first one is OK and the second one makes an exception.
Looking at the below code you can see that I have a separate Connection for each Insert Statement.'OPEN CONNECTION TO ESOSQL MyConnection = New SqlConnection("......") MyConnection.Open()

MyCheck = New SqlCommand("SELECT * FROM ARREST_CHARGES WHERE ARRESTNO = '" & Session("uid") & "'", MyConnection) MyCheck.CommandType = CommandType.Text MyDataReader = MyCheck.ExecuteReader

MyConnection1 = New SqlConnection("...") MyConnection1.Open()
MyInsert = New SqlCommand("INSERT INTO ARREST_INDEX (ARRESTNO, NOTES) VALUES ('" & Session("uid") & "','" & tx_notes.Text & "')", MyConnection1)
Label1.Text = "" Else div1.Style.Add("display", "block") Label1.Text = "You must enter charges before proceeding." End If MyConnection.Close()One would think I should only have to use one connection. However, if I use only one I get this error:There is already an open DataReader associated with this Command which must be closed first.

This seems to me as very inefficient. Can anyone explain why I couldn't just use one connection?Thanks.

I have created a data reader to loop thru a table and build an update statement. Now I need to execute this statement in the datareader loop but the connection object is in use.
I tried creating another connection object but get an error: "The context connection is already in use."
Is there a way to open another connection while the main context connection is open. Just to make it clear, I do not want to read all the rows into memory first and then call update, it has to happen for each iteration of the datareader.
I have the following SQL statement in the DataReader.SQLCommand.
select * from myTable where DataEdited > 'some hard coded date data'
I want to read the above 'some hard coded date data' from a table sitting in different database which is not the same server where the DataReader is connected.
How to do that?
I can populate the 'some hard coded date data' to a SSIS variable but do not know how to embed that in the SQL statement.

I have a multiple form project for a Windows CE 5.0 device (Symbol MC3000) written in VB.NET (Visual Studio 2005) using SQL Server Compact 3.5.
If I create the database on the SD Card, the program works fine until the unit is "suspended". When the power resumes, I can still continue to work and save/access data in the database as long as I do not go to another form. If I go to another form, I get an access violation error (0xC0000005).
If the database is installed in main memory the prorgam works properly even after the power is cycled.
Unfortunately, due to the memory size restrictions on the device, there are cases where the database needs to be stored on the SD Card.
Currently the program uses a single "global" SQLCeConnection and the connection is closed prior to the device being powered off. However, each procedure/event in the program uses it's own SQLCeCommand and SQLCeDataReader objects (which are created and closed/disposed prior to the end of the procedure).
I have tried everything I can think of, including OS updates, .NET Compact Framework 2.0 updates and modifications to the program to correct this, but the results are the same.
Would creating a global SQLDataReader and SQLCeCommand object help with this issue or should the way that this is currently being handled work?
Hello, I get the following error when I run my package interactively. From the logs written out by the driver, it appears that all is working well as far as connecting to the data source and pulling data. It seems as if this error occurs when the DataReader source tries to process the received data.

During our DR drill we found that the same code which used to run perfectly fine on our Primary Data Centre is running very slow on Disaster Recovery DB Server and there are Lot's of open transaction with sleeping status and waittype as 'AWAITING COMMAND'.CPU, Memory and disk utilization are good. The ping reply between the app server and the DB server is well within the limit's even blocking is not their, also nothing is reported in the error logs. We are using SQL server 2014 STD 64 BIT on Windows Server 2012.
i am using a OLE DB Source in my dataflow component and want to select rows from the source based on the Name I enter during execution time. I have created two variables,
enterName - String packageLevel (will store the name I enter)
myVar - String packageLevel. (to store the query)
I am assigning this query to the myVar variable, "Select * from db.Users where (UsrName = " + @[User::enterName] + " )"
Now in the OLE Db source, I have selected as Sql Command from Variable, and I am getting the variable, enterName,. I select that and when I click on OK am getting this error.
Error at Data Flow Task [OLE DB Source [1]]: An OLE DB error has occurred. Error code: 0x80040E0C. An OLE DB record is available. Source: "Microsoft SQL Native Client" Hresult: 0x80040E0C Description: "Command text was not set for the command object.".
Can Someone guide me whr am going wrong?
myVar variable, i have set the ExecuteAsExpression Property to true too.
I have a problem with DataReaderSource. I'm trying to get data from Notes table. I created a Connection manager and the connection was successful. The SQLCommand in "Component properties" tab is a simple "select * from <table_name>". When I switch to the "Column mappings" tab, only the first column from the table is displayed. Pressing the "Reftesh" button resulst in the following error: Error at Data Flow Task {DTS.Pipeline]: The "output column <column_name> has a length that is not valid. The length must be between 0 and 4000. When I go to the "Input and Output Properties" tab, the DataType for the output column is not populated and the error message "Error in Data Flow Task [DTS.Pipeline]: The output column <column_name> had an invalid datatype (0) set." The DataType property is not populated at all. Changing the data type to DT_STR results in error: "Property value is not valid". Details: Error at Data Flow Task [DataReader Source]: The data type of output columns on the component "DataReader Source" cannot be changed".
I read on a previous post to explicitly convert field , and tried to explicitly covnert the dataype on the field in my query (ex. select convert(varchar(50) from fieldname)
It then gives foll err:

I get an error at the end of a 47 million row job when I use the datareader source. It goes through all the records and then the package fails. The error (DataReader Source [1]] Error: System.NullReferenceException: Object reference not set to an instance of an object. ) occurs at the datareader source. I suspect it's because my record set returns a null value at some point. Any ideas?

I call the datareader using a sqlCommand that I programmatically build and it accesses the database fine. I can use the exact SQL command that I generate and I can get a result when i run it in SQL Management Studio. When I run the application and try to access the datareader, it throws an exception whose message is quite frustratingly, <column name>, or in this case "image_URL". Anyone have any idea what might be causing such an ambiguous error?
Hi, I am trying to import data from Oracle RDB into SQL Server 2005 using SSIS. Created a ODBC data source to connect to Oracle and used DataReader Source component and ADO.net to connect to the ODBC data source.
Under the Component properties tab, the SQL Command looks something like this.
Select ID, ADDRESS, REVISED from ADDRESS
The data type for the source columns are Integer, Varchar(30) and DATE VMS.
Now when I look at the Input and Output properties window,
The External columns has the following data types.
ID - four-byte signed integer [DT_I4] ADDRESS - Unicode string [DT_WSTR], length = 0 REVISED - database timestamp [DT_DBTIMESTAMP]
The Output columns has the following data types
ID - four-byte signed integer [DT_I4] ADDRESS - Unicode string [DT_WSTR], length = 0 REVISED - database timestamp [DT_DBTIMESTAMP]
When I tried to change the length of the ADDRESS on the output column, I get the following error.
Error at Data Flow Task [DataReader Source [1]]: The data type of output columns on the component "DataReader Source" (1) cannot be changed.
Is this the default length for the Unicode string type. I was not able to load the ADDRESS column as it gets truncated before I load it into destination. Even if I use Derived or Data Conversion transformation, the ADDRESS is getting truncated before it reaches this transformation.
Hi. I am writing a program in C# to migrate data from a Foxpro database to an SQL Server 2005 Express database. The package is being created programmatically. I am creating a separate data flow for each Foxpro table. It seems to be doing it ok but I am getting the following error message at the package validation stage:

Problem:
When adding the DataReader Source component to the package, I cannot assign the Connection Manager. Designer issues the error message:
"The runtime connection manager with the ID "" cannot be found. Verify that the connection manager collection has a connection manager with that ID."
Editing the DataReaderSrc component shows only one row under the Connection Managers tab:
The datareadersrc component editor displays the warning message: "Not all connection managers have been set. Set all connection managers.". Clicking the Refresh button causes the error message to be displayed "The runtime connection manager with the ID "" cannot be found. Verify that the connection manager collection has a connection manager with that ID."
I am prevented from assigning my Connection Manager object the DataReaderSrc.
The package already contains one Connect Manager object:
Provider: .Net Providers/Odbc Data Provider System DSN
I have a data source that I access via odbc in a DataReader Source component in SSIS. I can access the data fine. However, I am having problems with certain fields that are numeric (specifically home prices ranging from 100,000.00 to 99,999,999.00). In the advanced editor for my data reader source under the input and output properties tab, in data reader output under the external columns and output columns, these fields for some reason default to numeric data types with a precision of 4 and a scale of zero, not large enough to hold the data that is coming in. This causes errors that make the data come in as null (after i specify to ignore the errors).
I can change the precision and scale to 18 and 4 in the external columns, but when I try to change the datatype, precision or scale in the output columns I get the following message:
Property Value is not valid.
The details are:

I have small problem with the ADO 2.6 - 2.8 Command object.
I created a Stored procedure preforming some tasks within a tran.
whitin the tran i'm collecting the @@ERROR values and in the end (after tran closing )generating the correct error string - which will be send back to the caller
in the VB6 app, i'm using a command object with the next line:
Set MyRecordset= MyCommand.Execute
In all the cases and option, when i run the SP - the command preform the tasks and return closed recordset (with the currect answer) and i can't read it.
the only solution that worked until now: i need to call MyRecordset.Open which will requery the SP again and generate an error (User defined error).
It happens only when i run command.execute with SP that preforms multitasks and return result recordset.
Hi, I am accessing an MSDE Database from within a C# program. When calling the OleDbConnection.Open() method, I get the following error:
Exception: System.Data.OleDb.OleDbException Message: Object was open. at System.Data.OleDb.OleDbConnection.ProcessResults(Int32 hr) at System.Data.OleDb.OleDbConnection.InitializeProvider() at System.Data.OleDb.OleDbConnection.Open()
Now I do not know what this means, since the Connection isn't open. And I do not know why this occurs. I am accessing the same database (but other tables) in the same program several times in the same way and do not get this error.
One of my clients is accessing SQL Enterprise Manager via Citrix. He is getting an error message 'Unexpected error occured during this operation' while opening tables and displaying all rows in Enterprise Manager.
When I try the same thing through Enterprise Manager installed locally on my PC, I do not get any errors.
