Command Doesnt Support Executereader
Nov 26, 2006
Code:
connstr = "my connction info"
Set objConn = Server.CreateObject("ADODB.Connection")
objConn.Open connstr
Set objCmd=Server.CreateObject("ADODB.Command")
set objCmd.ActiveConnection = objconn
objCmd.CommandText = "my stored procedure"
objCmd.CommandType = 4
objcmd.parameters.append objcmd.createparameter("@itemcheckduplicate", 200, 1, 30, itemadd)
SqlDataReader forduplicate = objcmd.ExecuteReader()
my procedure :
@itemcheckduplicate varchar(30)
as
select sw_item_itemid
from sw_item
where sw_item_item like @itemcheckduplicate
why my command doesnt support ExecuteReader ?
Microsoft VBScript runtime error '800a01b6'
Object doesn't support this property or method: 'ExecuteReader'

HI I am having problem with my Execute Reader. I am trying to insert values from 2 different tables into another table. SqlCommand comm2; SqlDataReader reader2; /* Grabs the stuff out of the database */
comm2 = new SqlCommand("SELECT HiraganaCharacter,HiraganaImage FROM Hiragana", getConnection()); /* opens the database */
comm2.Connection.Open();
/* starts the reader */
reader2 = comm2.ExecuteReader();
/* goes through the first array list */
for (int i = 0; i < checkedLetters.Count; i++) { /* find the data by using the array list value as a where clause */ comm2.CommandText = "SELECT HiraganaCharacter,HiraganaImage FROM Hiragana WHERE HiraganaCharacter ='"
+ checkedLetters[i] + "'"; /* reads through the data */ reader2.Read(); /* puts the ID- this id was set somewhere else */ CommQuickLinksItems.Parameters["@QuickLinkID"].Value = QuickLinkId; CommQuickLinksItems.Parameters["@CharacterName"].Value = reader2["HiraganaCharacter"].ToString(); CommQuickLinksItems.Parameters["@CharacterImagePath"].Value = reader2["HiraganaImage"].ToString(); CommQuickLinksItems.ExecuteNonQuery(); } for (int j = 0; j < checkedLettersKata.Count; j++) { comm2.CommandText = "SELECT KatakanaCharacter,KatakanaImage FROM Katakana WHERE KatakanaCharacter ='"
+ checkedLettersKata[j] + "'"; reader2.Read(); CommQuickLinksItems.Parameters["@QuickLinkID"].Value = QuickLinkId; /* line it dies on */ CommQuickLinksItems.Parameters["@CharacterName"].Value = reader2["KatakanaCharacter"].ToString(); CommQuickLinksItems.Parameters["@CharacterImagePath"].Value = reader2["KatakanaImage"].ToString(); CommQuickLinksItems.ExecuteNonQuery(); } CommQuickLinksItems.Connection.Dispose(); CommQuickLinksItems.Dispose(); comm2.Connection.Dispose(); comm2.Dispose(); My first question is there a better way to setup a SqlCommand to just get the connection and wait on the Command object text? Right now I am doing comm2 = new SqlCommand("SELECT HiraganaCharacter,HiraganaImage FROM Hiragana", getConnection());Which is kinda pointless since in the for loop I change the command to something different right away. At the same time though I don't really want to make a new SqlCommand object in the for loop since then everytime it goes through the loop it would then re grab the connection what I find pointless tooNow the problem How I have it right now it does not grab the right stuff. The first for loop works great and everything gets inserted. The next loop does not work It seems like it it trying to take the data from the first for loop and insert that stuff again since I get this error System.IndexOutOfRangeException was unhandled by user code Message="KatakanaCharacter" Source="System.Data" StackTrace: at System.Data.ProviderBase.FieldNameLookup.GetOrdinal(String fieldName) at System.Data.SqlClient.SqlDataReader.GetOrdinal(String name) at System.Data.SqlClient.SqlDataReader.get_Item(String name) at Practice.QuickLinks() in g:WebsiteJapanesePractice.aspx.cs:line 385 at Practice.btnQuickLink_Click(Object sender, EventArgs e) in g:WebsiteJapanesePractice.aspx.cs:line 411 at System.Web.UI.WebControls.Button.OnClick(EventArgs e) at System.Web.UI.WebControls.Button.RaisePostBackEvent(String eventArgument) at System.Web.UI.WebControls.Button.System.Web.UI.IPostBackEventHandler.RaisePostBackEvent(String eventArgument) at System.Web.UI.Page.RaisePostBackEvent(IPostBackEventHandler sourceControl, String eventArgument) at System.Web.UI.Page.RaisePostBackEvent(NameValueCollection postData) at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) InnerException: Basically what I did was for the first loop I chose 2 items and for the 2nd loop I chose 3 items. When it died on this line CommQuickLinksItems.Parameters["@CharacterName"].Value = reader2["KatakanaCharacter"].ToString();The value was "i" but that was one of the values I choose for the first for loop. It should have been either u,e,o. So I am not sure what I am doing wrong. I thought as long as I change the Command text I would not need to do anything else but it seems like I am missing something.

I am currently tryinh to have this variable declared : Dim SQLLecteur As SqlDataReader = Command.ExecuteReader()And receiving the following error : 'ExecuteReader' is not member of 'String'.1. The ExecuteReader was not present in the list following the Command.2. The variable is declared from a : Public Shared Sub3. This sub is located in a code library referenced in the web.config as a namespace : <add namespace="PAX20070409" />4. If used directly in the .vb file within this sub : Protected Sub btnConnection_Click, I am not receiving any errors about the Dim.It is pretty clear why the code is not working, but I have not been able to find a way to fix the problem. I am currently trying to find a way to make the Dim work from within my code library. If you have any idea on how this could be achieve, it would be greatly apreciated.Thank you :)RV3

Hello,I would like to know whether it is possible to execute DTS(Data Transformation Services) packages created from withinthe EM (Enterprise Manager) user interface, from the commandline. That is, is it possible to execute a command at the DOSprompt which will execute, and optionally also reconfigure,the DTS package? This would allow invoking DTS packagesfrom within scripts.Thank you for your replies,Neil

I've heard that the Standard version supports the use of CommandNotification and that the Express version does not. What about the Workgroup edition?
The reason I'm asking is because there is a substantial monthly difference in cost between the two versions if I were to have my site hosted. I've been developing with MS SQL 2005 Express so obviously I have not tested this caching feature. Are command notifications reliable? On paper, it sounds impressive and extremely efficient especially if a site is to have heavy traffic and you can't afford the overhead of heavy database processing that is useless if the data is unchanged.
Does the Workgroup edition support automatic change notifications? Have automatic notifications been proven reliable and vastly more efficient than crude polling methods?
Thanks in advance.

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.
thanks

Reader Community
I've just started hosting my newly created Microsoft Visual Web Developer 2005 Express Edition web site. Unfortunately the Login group membership functions will not function correctly. Having contacted the web service hosting provider, They replied: "We do not support SQL express2005. The only way to use the extra functions of ASP.NET2 such as group membership is if it is using an SQL 2000 database to connect to. "
Is it possible to design web sites with Microsoft Visual Web Developer 2005 Express Edition that store membership details on an SQL 2000 database?
I've just paid £88 approx. $140 for a years subscription, have I chosen the wrong web service hosting provider?
Should I have designed the web site with a better web site design software tool that also makes designing membership login functionality easy, just as Microsoft Visual Web developer 2005 express edition?
Look forward to all comments?
Regards
Philip

Hi.
I'm trying to read data from a database. This is my code:
++++++++++++++++++++++++++++++++++++++++++++++++++++++++
connection.Open();SqlCommand cmd = new SqlCommand(sql, connection);
myReader = cmd.ExecuteReader();if (myReader.Read())
{
name1TextBox.Text = myReader.GetString(1);
addr1TextBox.Text = myReader.GetString(2);
code1TextBox.Text = myReader.GetString(5);
tel1TextBox.Text = myReader.GetString(6);
fax1TextBox.Text = myReader.GetString(7);
:
:
++++++++++++++++++++++++++++++++++++++++++++++++++++++++
The above code works fine until one of the GetString calls trys to return NULL (in this case myReader.GetString(5)).
In other words, this code will run through about 30 rows of data until it runs in to a NULL entry for one of the columns.
At that stage it's too late. I'm not allowed call GetString( ) on a NULL value.
Is there anyway I can test the column entry before calling GetString( ).
Regards (& thanks in advance)

when I execute the line:
reader = comm.ExecuteReader();
Is there a way to get a count of the number of records returned (the query is a SELECT with no count in it)? I want to vary the display of the results set based on the number of records returned.
For example if no records are returned I want it to display nothing, if one, I want the header to be in the singular, but if more than one record is returned, I want it to display the header in plural form.
Here is my code snippet with further explanation of what I am trying to do:int Inumber = 0;foreach (string item in menuHeaders)
{string title = menuHeaders[Inumber];
sp.Value = menuHeaders[Inumber];
Inumber++;
conn.Open();reader = comm.ExecuteReader(CommandBehavior.CloseConnection);
//Get the culture property of the thread.CultureInfo cultureInfo = Thread.CurrentThread.CurrentCulture;
//Create TextInfo object.TextInfo textInfo = cultureInfo.TextInfo;
// WHAT I AM TRYING TO DO....... Here I would like to wrap this with an if statement, if Records returned by the reader are 0, skip while loop and header display
// If one, then display in singular and if 2 add an s to the title. Convert to title case and display.content.Text += "<H3>" + textInfo.ToTitleCase(title) + "</H3>";while (reader.Read())
{
content.Text += "<a href='" + reader["website"] + "'>" + reader["f_name"] + reader["l_name"] + "</a>"+ ", " +reader["organization"]+"<br />";
}
//Close the connection.
reader.Close();
conn.Close();

Hi. I am executing a stored procedure. The stored procedure raises an error and all I need is to catch this error. Pretty simple, but it only works with an ExecuteNonQuery and not with an Executereader statement. Can anybody explain to me why this happens?
Here's the sp:
CREATE PROCEDURE dbo.rel_test
AS
select 1
raiserror ('My error.', 11, 2)
return
GO
Here's the ASP.Net page:
<% @Page Language="VB" debug="True" %>
<% @Import Namespace="System.Data.SqlClient" %>
<script runat="server">
Public Function RunSP(ByVal strSP As String) As SqlDataReader
Dim o_conn as SqlConnection = New SqlConnection(ConfigurationSettings.AppSettings("connectionstring"))
AddHandler o_conn.InfoMessage, New SqlInfoMessageEventHandler(AddressOf OnInfoMessage)
o_conn.Open
Dim cmd As New SqlCommand(strSP, o_conn)
cmd.CommandType = System.Data.CommandType.StoredProcedure
Dim rdr as SqlDataReader = cmd.ExecuteReader(System.Data.CommandBehavior.CloseConnection)
rdr.Close()
cmd.Dispose()
Response.Write(o_conn.State)
End Function
Private Sub OnInfoMessage(sender as Object, args as SqlInfoMessageEventArgs)
Dim err As SqlError
For Each err In args.Errors
Response.Write(String.Format("The {0} has received a severity {1}, state {2} error number {3}" & _

I am not seeing why this is not executing the reader, it just goes right by it when stepping through the code...
command.CommandType = CommandType.StoredProcedure;
// course
command.Parameters.Add( "@courseId", courseId );
// Parameter: LessonName
SqlParameter sLessonName = command.Parameters.Add( "@lessonName", SqlDbType.VarChar );
sLessonName.Size = 256;
sLessonName.Direction = ParameterDirection.Output;
// error code
SqlParameter pErrCode = command.Parameters.Add( "@errCode", SqlDbType.Int );
pErrCode.Direction = ParameterDirection.Output;
// execute the stored procedure
SqlDataReader spResults;
conn.Open();
spResults = command.ExecuteReader();
while( spResults.Read() ) // It never steps into the while statement like the reader is completed
{
RetrieveObjId objNames = new RetrieveObjId( spResults.GetString( 0 ));
searchResults.Add( objNames );
}
spResults.Close();And the stored procedure is.....CREATE PROCEDURE dbo.retrieveLessonNames @courseId VARCHAR(20), @lessonName VARCHAR(256) OUTPUT, @errCode INT OUTPUT ASBEGIN
SELECT @lessonName = objName FROM objStructure WHERE courseId = @courseId
SET @errCode = 0 RETURN @errCode HANDLE_APPERR: SET @errCode = 1 RETURNHANDLE_DBERR: SET @errCode = -1 RETURNENDGOSuggestions?Thanks all,Zath

I have VS 2005 and SQL CE 3.0. I sometimes get the a FileNotFoundException when I first use ExecuteReader. I believe this is because a dll has not been copied across because if I restart the emulator I can get it to work again.
Do I need to add a cab file/dll to my project to stop this happening?
Thanks

Try
'The first this we need to do here is query the database and verify

id = cmd.ExecuteScalar()
Response.Write(id.ToString & "<BR>")
Catch
Response.Write(sql & "<BR>")

Finally
If Not id.ToString Is Nothing Then

Else

Hello and thanks in advance.
This error was received executing a SqlCeCommand method of ExecuteReader();
I have only found 3 hits in Google about this error and the time it was asked in a MS forum it was not answered. I need an answer, please.

Hi,
I have written a CLR Function in C#. The function works as expected except that I am trying to read data some data during the function call and get the following error:
Msg 6522, Level 16, State 1, Line 1
A .NET Framework error occurred during execution of user-defined routine or aggregate "fn_SLARemaining":
System.InvalidOperationException: ExecuteReader: Connection property has not been initialized.
System.InvalidOperationException:
at System.Data.SqlClient.SqlCommand.ValidateCommand(String method, Boolean async)

at UserDefinedFunctions.fn_SLARemaining(SqlDateTime DateFrom, SqlDateTime DateTo, SqlInt32 PriorityTime, SqlDecimal AdjustmentTime, SqlDecimal Status)
.
The main code for the function is this:
using System;
using System.Data;
using System.Data.SqlTypes;
using System.Data.SqlClient;
using Microsoft.SqlServer.Server;
public partial class UserDefinedFunctions
{
[Microsoft.SqlServer.Server.SqlFunction(DataAccess = DataAccessKind.Read)]
public static SqlString fn_SLARemaining(SqlDateTime @DateFrom, SqlDateTime @DateTo, SqlInt32 @PriorityTime, SqlDecimal @AdjustmentTime, SqlDecimal @Status)
{
SLARemaining.CalculateTimeRemaining remaining;
remaining = new SLARemaining.CalculateTimeRemaining();
int duration = Convert.ToInt32(PriorityTime.ToString());
if (!DateFrom.IsNull)
{
string date = DateFrom.Value.ToShortDateString() + " " + DateFrom.Value.ToShortTimeString();
SqlString result = remaining.GetTimeRemaining(date, duration);
return result;
}
else
{
return null;
}
}
};
The function calls the following method from another class:
public string[] addSupportHours()
{
string[] supportedHours = new string[28];
SqlDataReader dr;
SqlCommand cmd = new SqlCommand();
cmd.CommandText = "xxxxxxx"; //<-- commented out for this post
using (SqlConnection cn = new SqlConnection("context connection=true;"))
{
cn.Open();
dr = cmd.ExecuteReader();
while (dr.Read())
{
//do some stuff
}
cn.Close();
cn.Dispose();
}
The error message claims that the connection has not been initialized - can't work out why? Any help will be appreciated!

I am accessing SQL2005 with C# code using OleDbConnection.
A try and catch block catches the following error once a while between the Open() and Close() of the connection:
ExecuteNonQuery requires an open and available Connection. The connection's current state is closed.
I do not even have any idea where to start to debug this. The ExecuteNonQuery() runs a delete SQL query. It works 99.9% of the time. I do not see anything wrong when this error happens.
Any hint would be greatly appreciated.

Hi All,
This is reletaed to SQL Server 2005.
I have a backup file that does not have any .bak extension and I am trying to restore it against a already existing DB. Thats the first time I am dealing with a backup that does not have a .bak extension and I dont know how to restore it.
The .bak backups are easy to restore and I restore it in SQL 2005 managment studio with the following steps;
a) I right clicking on the existing database (where I want it to be restored) and b) then click Tasks , c) click Restore, and d) click Database, and e) then in the restore database window click 'From device', f) then click '...' to browse and g) click add to browse and add the backup file to be restored.
I am doing the above steps for the non .bak extension backup file but I am unable tio add the file?
In SQL 2005 managment studio how can I restore a backup (that doesn't have .bak extension) against a exsisting database?
Please help.
Thanks a million.
Zee

Can someone tell me why this thing in the end return Null?
declare @uz_id uniqueidentifier
set @uz_id=null
set @uz_id=
case @Uz_ID
when null then '00000000-0000-0000-0000-000000000000'
else @Uz_ID
end
select @uz_id
...it should return '00000000-0000-0000-0000-000000000000' in my opintion
P.S. When I say return i mean the value that is shown after 'select @uz_id' is executed:)

INSERT INTO SALHISTY(EMPLOY_REF, SALARY, SAL_REASON, SAL_DATE)

Can anyone help,
I have created a report which works great when the users run from IE6, but when anyone runs report from IE7, the report displays ok, but the document appears to build but displays absolutely nothing.
Has anyone seen this problem with IE7 using Reporting Services 2000?
Thanks people

I have the following in my commandtext but it doesnt seem to replace the LanguageColumnName variable: Dim cmd As New SqlCommand("SELECT '+@LanguageColumnName+' FROM tblSports a INNER JOIN tblUsersAndSports b ON a.SportID=b.SportID " & _ "WHERE b.UserCode=@UserCode", MyConnection) cmd.Parameters.Add(New SqlParameter("@UserCode", UserCode)) cmd.Parameters.Add(New SqlParameter("@LanguageColumnName", LanguageColumnName))I have tried '+@LanguageColumnName+' and also just @LanguageColumnName but this variable isnt replaced for some reason.The value of LanguageColumnName is "de"...the funny thing is that when I just type my command like the following it DOES work..:SELECT de FROM tblSports a INNER JOIN tblUsersAndSports b ON a.SportID=b.SportID " & _ "WHERE b.UserCode=@UserCodeWhat am I doing wrong?

Hello,
Im having a problem with this query....SELECT a.ref, COUNT(b.entrypage) AS counter
FROM SiteCore.dbo.Campaigns AS a LEFT OUTER JOIN
webStats AS b ON b.entrypage LIKE '%?ref=partners%'
GROUP BY a.ref
But i want it to look more like this, so it pulls the approprite rows its selfSELECT a.ref, COUNT(b.entrypage) AS counter
FROM SiteCore.dbo.Campaigns AS a LEFT OUTER JOIN
webStats AS b ON b.entrypage LIKE '%?ref=' + a.ref + '%'
GROUP BY a.ref
The first one return the correct count where as the latter doesnt retuen anything, could any one shed any light as to what the problem could be?
Thanks
Bart

I am trying to select records based upon last name
WHERE (Last_Name BETWEEN 'A%' AND 'C%')
When I run this I get only last names starting with A and B--no C. ?!?
This is confusing to me....I ran it with lastname >= 'A%' and lastname <='C%'and it returned only names starting with B. Why does SQL ignore the "="
I hope this isnt obvious :/
