Problem Inserting Data Into SQL Server 2005 DB From WebForm Controls

Mar 30, 2007

Hello all,

I am having problems running a stored proc from an aspx.cs file. Basically I want to extract data from webForm controls and create a new record in a DB table. I have watched the "Getting Started" videos on thi site, and the only difference between my code and the code of the demonstrator is the connection string.   My conn string:- dataSrc.ConnectionString = ConfigurationManager.ConnectionStrings["ProjectTblConnString"].ConnectionString;Demonstrator conn string:- dataSrc.ConnectionString = ConfigurationManager.ConnectionStrings("ProjectTblConnString");When I debug with the string as shown by the demonstrator the error list reports that ConnectionStrings is a property and I am trying to use it as a mothod,
which is fair enough, but I am just confused as how it worked for the demonstrator and not myself. When I debug with the code I used above I get no error, but nothing is inserted in the DB.Also, it looks as if the only class in my aspx.cs file that is actually being executed is PageLoad() - the remainder of the code seems to be ignored. Below is the entired aspx.cs file:- 1 using System;
2 using System.Data;
3 using System.Configuration;
4 using System.Collections;
5 using System.Web;
6 using System.Web.Security;
7 using System.Web.UI;
8 using System.Web.UI.WebControls;
9 using System.Web.UI.WebControls.WebParts;
10 using System.Web.UI.HtmlControls;

12 public partial class CreateProject : System.Web.UI.Page

23 {

26 }

28 }

30 protected void btn_create_Click(object sender, EventArgs e)
31 {
32 //connection string for connecting to SQL Server DB
33 SqlDataSource dataSrc = new SqlDataSource();
34 dataSrc.ConnectionString = ConfigurationManager.ConnectionStrings["ProjectTblConnString"].ConnectionString;
35
36
37 //insert data in table using the CreateNewProject stored proc in the DB
38 dataSrc.InsertCommandType = SqlDataSourceCommandType.StoredProcedure;
39 dataSrc.InsertCommand = "CreateNewProject";
40 dataSrc.InsertParameters.Add("Project_Title", txtbox_title.ToString() );

Best Way To Insert Large Amounts Of Data From A Webform To SQL Server 2005

Oct 21, 2007

HiI have a VB.net web page which generates a datatable of values (3 columns and on average about 1000-3000 rows).What is the best way to get this data table into an SQL Server? I can create a table on SQL Server no problem but I've found simply looping through the datatable and doing 1000-3000 insert statements is slow (a few seconds). I'd like to make this as streamlined as possible so was wondering is there is a native way to insert all records in a batch via ADO.net or something.Any ideas?ThanksEd

Porting VB 6 Data Controls To Use SqlDatasource Controls - Please Help!!!!

May 9, 2007

Hi,  I am porting a massive VB6 project to ASP.net 2005.  Most of the code is fine, however because the original developers used lots of data controls and my own time restrictions I thought to replicate the functionality by using Sqldatasource controls instead. 
 These data controls are bound to DBtruegrids.   The project has has lots of code like...
 AdodcOrders.Recordset.RecordCount > 0 or  If AdodcOrders.Recordset.EOF  or  AdodcOrders.Recordset.MoveNext()  or
AdodcDetail.Recordset!FieldName
The problem is the sqldatasource control doesn't have a recordset/dataset property which I can access and manipulate, or does it?  What should I do to get round these?  The project has thousands of lines like this in so its not feasible to rewrite it (although if I could I would!).
 Any suggestions please gratefully appreciated.
many thanks
mike

Microsoft SQL Server 2005 Datamining Viewer Controls Feature Pack

Oct 24, 2006

Hi,

I downloaeded "Microsoft SQL Server 2005 Datamining Viewer Controls" feature pack, and tried to run the dataminingviewerclient.exe.

When i view my local time series data mining model, It works well for single series model, but when i load a Microsoft time series model containing multiple data series, an unhandled exception occurs.

I post the error message below:



See the end of this message for details on invoking

Inserting Data In SQL 2005 Using Javascript From A Form Object

Mar 4, 2008

I am new to ASP.NET. At present i am developing a web application in which i need to insert data in database(MS SQL 2005) from a form which uses only HTML controls. I need to use HTML controls so posting of form to the server is not done and hence i need to generate HTML controls using javascript. So the data in the form must be stored in the database. How this data can be inserted in the database is the problem and i think that javascript might be the solution for it.

Working In VB.Net 2005 Inserting NULL Into A Field In Microsoft SQL Server 2005

Feb 2, 2007

I am update/inserting records threw a web form in vb.net. I need to insert 'NULL'  into my microsoft sql server database.  I am not talking about the below line of code where website is the name of my paramater.  If i do that it will just place a blank into that field in the database.  If i dont enter anything into that textbox I want it to to say NULL in that field. So if I go into the actual table in the SQL Server Management Studio and look at the website field of the recored I just added or updated and did not type anything into the web site textbox it needs to say NULL.  I also tried the second line of code but that places a single quote in front and behind NULL. So the field will have the value 'NULL'.
website.value = txtwebsite.text.tostirng
 if txtwebsite.text ="" then
   website.value ="NULL"
end if
The reason why I need the NULL there is because I bind the website filed to a hyperlink template in a gridview.  The actual text of the hyperlink is bound to PAYER which is a name of a insurance payer but the navigateto is bound to the website field.  If i do not enter any data into the website field and it stays as NULL, then when my gridview is loaded, payers that dont have a website will not be underlined and user wont have the option to click on them since there is no value for the navigateto.  But if i use my form to update/add a payer and leave the website textbox blank in puts a blank into that field in my database and when it loads that new row into the gridview the PAYER is underlined and u can click on it but it will just take u to the web site is unavailable page.  So is there anyway to actaull have NULL placed into a filed and not just blank space

Data Mining Web Controls

May 13, 2007

Hi ... hope you can help.

I would like to use the Data Mining Web Controls which ship with the MSSQL2005 Beta 2. The installer (BetaAnalysisServicesSamples.MSI) is supposed to create a new virtual directory and should also create the DataMiningHTMLViewers.dll according to "ReadMe_Data_Mining_Web_Controls.rtf"

But the MSI only creates a few new directories with the source code and a deployment project (DMHTMLViewersSetup.vdproj) which won't open with VS2003. The solution apears to be for VS2005.

How do I install the Web Controls?

Trying To Insert Form Controls And Another Data Source

I'm trying to insert data into a table from two sources (a table and form controls) at the same time.   
--this data from the tradeitem table and is inserted into the selections table
--based on the variable @builderid --no problem it works fine as is
INSERT INTO Selections ([TradeItemID], [TradeID], [ProductName], [OrigSalesPrice], [RevSalesPrice])
SELECT [TradeItemID], [TradeID], [TradeItem], [Price], [Price]
FROM tradeitems
WHERE BuilderID = '1'
However, I need these also to pull from the form controls
--These variables will pull from form controls and need to be associated
--with each record added to the seleciton table
INSERT INTO Selections ([UserDataID] = '1', [DefaultQty] = '0')
--How do I get these combined into one statement so I get the following result?

Data Access, DataReaders, DataSets, Web Pages And Controls

May 10, 2007

I have a question about loading data on the page lode event. The question is more conceptual then how to.
 
Using C#, I would like to make a call to a SQL 2000 Server, with the use of a stored procedure return one row with eleven fields. Then use the data to fill five different controls. There is no manipulation of the data it is just presented as information. With a DataReader and the GetValues method using the resultant array I can fill the controls (or can I), or with a DataSet and the Load method do the same thing. Now this code can be placed in the code behind page or it can be implemented in a class. This is the only page that uses this combination of fields and controls; however I would think a more generic call to the data could be made then pick and chose the fields as needed. What process makes the most sense? Is what I just described even possible (as yet I haven’t tried it)?
 
As always thanks in advance for any thoughts, comments, and suggestions.

Extract Data And Populate Values Into The Respective Controls

Apr 16, 2008

Hi!

I am creating a scheduling web application. I have managed to insert data into the database. The code is as follow:

Dim insertSQLDatasource As New SqlDataSource()
insertSQLDatasource.ConnectionString = ConfigurationManager.ConnectionStrings("ScheduleConnectionString").ToString

insertSQLDatasource.InsertCommandType = SqlDataSourceCommandType.Text
insertSQLDatasource.InsertCommand = "INSERT INTO Demo_Theatre_DB (StartTime, EndTime, CompanyName, Purpose, AccountManager, Presenter, ColorCode, Status, Comments) VALUES (@StartTime, @EndTime, @CompanyName, @Purpose, @AccountManager, @Presenter, @ColorCode, @Status, @Comments)"

insertSQLDatasource.InsertParameters.Add("StartTime", StartTimeTextBox.Text)
insertSQLDatasource.InsertParameters.Add("EndTime", EndTimeTextBox.Text)
insertSQLDatasource.InsertParameters.Add("CompanyName", CompanyNameTextBox.Text)
insertSQLDatasource.InsertParameters.Add("Purpose", PurposeTextBox.Text)
insertSQLDatasource.InsertParameters.Add("AccountManager", AccountManagerTextBox.Text)
insertSQLDatasource.InsertParameters.Add("Presenter", PresenterTextBox.Text)
insertSQLDatasource.InsertParameters.Add("ColorCode", ColorDDL.SelectedValue.ToString)
insertSQLDatasource.InsertParameters.Add("Status", StatusRadioButtonList.SelectedValue)
insertSQLDatasource.InsertParameters.Add("Comments", CommentTextBox.Text)

Try
insertSQLDatasource.Insert()
Catch ex As Exception
Panel1.Visible = True
InsertMsgLabel.Text = ex.Message.ToString
Finally
insertSQLDatasource = Nothing
End Try

Now I am trying to select the values for a particular event. For example, if the user selects an event with id 40, the values that corresponds to that row will be read and filled into the respective controls. I tried the following code, but doesn't work.

Dim sqlConn As SqlConnection = New SqlConnection("ScheduleConnectionString")
Dim com As SqlCommand = New SqlCommand("SELECT * FROM Demo_Theatre_DB WHERE ID=@ID", sqlConn)
sqlConn.Open()
Dim r As SqlDataReader = com.ExecuteReader()
While r.Read()
StartTimeTextBox.Text = r("StartTime")
EndTimeTextBox.Text = r("EndTime")
CompanyNameTextBox.Text = r("CompanyName")
PurposeTextBox.Text = r("Purpose")
AccountManagerTextBox.Text = r("AccountManager")
PresenterTextBox.Text = r("Presenter")
ColorDDL.SelectedValue = r("ColorCode")
StatusRadioButtonList.SelectedValue = r("Status")
CommentTextBox.Text = r("Comments")
End While

I hope someone can help me with this.

Your help will be appreciated.

Thanks!

SQL Server 2012 :: Get Empty Data Set For Inserting Data?

Nov 11, 2014

I have 2 tables in my database.

one is Race table and 2nd one is Age Range.

I want to write a query where I can see all races and age range as column.

TblRace

ID, RaceName

TblAgeRange

ID,AgeRange.

There is no connection between this two table. I need to display result like below.

Race 17-20 21-30 31-40

A

B

How do i get this kind of empty data set so that I can fill it out in front end or any better solution. The age range will be displayed as many row as they have. It's not static. Above is just an example.

Inserting Data Into Ms SQL Server

Oct 8, 2007

I am trying to transition from Access to MS SQL. I downloaded and installed MS SQL 2005 Express and the Server Management Studio Express. Keep in mind that I am a total newbie to this database since I've always used Access. My question is, how do I insert data manually into my tables? I figured out how to set up a table and query a table, but is there somewhere I can just plug in data? In Access, I just open the table and type it in. Also, how do you set an auto increment numeric field in a table?- Jason

values("PP0073", @counter, "080464", "19990901", 1)
select @counter=@counter-1
end

HI there,
I run the above statement in Query Analyzer and the expected result should be 300,000 records inserted into Revenue table. But unfortunately the actual records inserted were less than 300,000. I also realise that it insert different amount of record each time I run it. Can anyone please tell me why?

Thanks,
Will

Inserting Data Into SQL Server

Sep 22, 2000

Hi, Everybody:

Could anyboby please tell me any way which can quickly inserting large data to SQL Server except using cursor?

Every morning, I use DTS to transfer around 100,000 data from foxpro to SQL Server 7.0 temporary table. Then I use cursor to check if the data already exist in the SQL Server table, then I do update; if the data does not exist in the SQL Server table, then I do insert into. In SQL Server database, each table already has over million record, also I have 12 table with the same situation.

Now I find cursor very slow to do above, can anybody tell me any way which can quickly to do update and insert?

Thank you very much.

They can create tables but cannot insert/update data (to their own tables), I cannot insert data either using Access or any other application to those tables created by them (under dbo schema) Is there something I am missing with permissions?

Problem In Inserting Data To SQL Server

Mar 12, 2008

Hi,
Just look at my Code:protected void Button1_Click(object sender, EventArgs e)
{SqlConnection Conn = new SqlConnection("MyConnectionString");
SqlCommand Cmd = new SqlCommand();string linktext,headline, quote, para1, para2, para3;
linktext = this.TextBox1.Text;headline = this.TextBox1.Text;
quote = this.TextBox2.Text;para1 = this.TextBox3.Text;
para2 = this.TextBox4.Text;para3 = this.TextBox5.Text;Cmd.CommandText = "insert into desieyenews(linktext,newsheadline,quote,para1,para2,para3) values ("+linktext+","+headline+","+quote+","+para1+","+para2+","+para3+")";
Cmd.Connection = Conn;
Conn.Open();
Cmd.ExecuteNonQuery();
Conn.Close();
 
}
 
Details: In the above code I am inserting data from 5 textbox to my databse. It works fine but when I am trying to insert text like Tom's..., problem occurs. Whenever I am trying to insert some text with a single quote, the problem arises. Although the datatype of my database is text in MS SQL Server 2005.
Please give me some solution so that I can get rid of this problem....
Thanks in advance.

Problems Inserting Datetime Object Into Sql Server 2005

Nov 22, 2007

hey everyone,

Im trying run a stored procedure, but I am getting the following message when trying to execute it.

Implicit conversion from data type datetime to int is not allowed. Use the CONVERT function to run this query.

which seems strange, as there is no integer going to a datetime field. Also, it does not return the value that is incorrect, nor the parameter that is failing. If there is anyway to view this in VS 2005 Team suite, please let me know.

It should also be noted that when I execute this sproc from within sql management studio, it executes fine.

This is the stored procedure im trying to execute...

CREATE PROCEDURE [dbo].[sp_UpdateRequest]

@request_id INT,
@request_client_id INT,
@request_description VARCHAR(150), @request_date DATETIME,
@request_edit_date DATETIME, @request_status VARCHAR(25), @request_approve_date DATETIME,
@request_activity_code VARCHAR(7), @request_department_code VARCHAR(3), @request_participants INT,
@request_activity_date DATETIME, @request_activity_due_date DATETIME,
@request_company_id INT, @request_company_code INT,
@request_notes VARCHAR(2000)

AS
BEGIN

UPDATE invoice_requests

SET request_client_id = @request_client_id,request_description = @request_description,
request_date = @request_date, request_edit_date = @request_edit_date,
request_status = @request_status, request_approve_date = @request_approve_date,
request_activity_code = @request_activity_code,
request_department_code = @request_department_code,
request_participants = @request_participants,
request_activity_date = @request_activity_date,
request_activity_due_date = @request_activity_due_date,
request_company_code = @request_company_code, request_company_id = @request_company_id,
request_notes = @request_notes

WHERE request_id = @request_id

END
GO

in my .net app, all the datetime objects are valid dates, so I could not see why this would be generating the error that it is, so I ran the SQL Profiler, and this was the output. Again, i cannot see where im going wrong...

please note, I have seperated the output from the single slab of text, making sure I didnt remove anything...

exec sp_executesql
N'EXECUTE sp_UpdateRequest
@request_id,
@request_client_id,
@request_description,
@request_date,
@request_edit_date,
@request_status,
@request_approve_date,
@request_activity_code,
@request_participants,
@request_activity_date,
@request_activity_due_date,
@request_company_id,
@request_company_code,
@request_notes',

N'@request_id int,
@request_client_id int,
@request_description varchar(8000),
@request_date datetime,
@request_edit_date datetime,
@request_status varchar(5),

@request_activity_code varchar(8000),
@request_department_code varchar(8000),
@request_participants int,
@request_activity_date datetime,
@request_activity_due_date datetime,
@request_company_id int,
@request_company_code int,
@request_notes varchar(8000)',

@request_id=5,
@request_client_id=1,
@request_description='',
@request_date=''2007-11-22 16:34:32:997'',
@request_edit_date=''2007-11-22 16:34:32:997'',
@request_status='Draft',
@request_approve_date=''1970-01-01 00:00:00:000'',
@request_activity_code='',
@request_department_code='',
@request_participants=0,
@request_activity_date=''2007-11-29 00:00:00:000'',
@request_activity_due_date=''2007-11-23 00:00:00:000'',
@request_company_id=0,
@request_company_code=1,
@request_notes=''

any help on this would be greatly appreciated.
Cheers

I have tried changing the COLLATE parameter of the database and tables while creating the database, but still the issue persists.
Please help me.
