Trouble Writing To A Database
Nov 13, 2007
I am trying to write to a database through C++ with the ODBC stuff. I can connect to and close the database as well as write certain things to it. I am having trouble writing strings or chars to it though. I'm not really a DB programmer and probably won't have to do it in C++ for a long time, so I'm just looking for some quick help so I can move on to other stuff. I know this code probably won't look right either since I;ve only seen this stuff for about 2 days now. Basically I have a string that I want to bind using SQLBindParameter so that I can use it in an ExecDirect statement. Basically when I run the little code snippet below, it writes some crazy character set out. Any help would be appreciated because I really have no clue what I'm doing.
SQLCHAR test1 = 'a';
SQLINTEGER test = SQL_NTS;
retcode = SQLBindParameter(hstmt, 1, SQL_PARAM_INPUT, SQL_C_CHAR, SQL_CHAR,0,0,&test1, 0,&test);

hi,
i am a nubie, and struggling with the where clause in my stored procedure. here is what i need to do:
i have a gridview that displays records of monthly view of data. i want the user to be able to page through any selected month to view its corresponding data. the way i wanted to do this was to set up three link buttons above my gridview:
[<<Prev] [Selected Month] [Next>>]
the text for 'selected month' would change to correspond to which month of data was currently being displayed in the gridview (and default to the current month when the application first loads).
i am having trouble writing the 'where' clause in my stored procedure to retrieve the selected month and year.
i am using sql server 2000. i read this article (http://forums.asp.net/thread/1538777.aspx), but was not able to adapt it to what i am doing.
i am open to other suggestions of how to do this if you know of a cleaner or more efficient way. thanks!

hi, I'm trying to write to a database from a web page. The code is throwing back no errors but it just isn't writing to the database. Am I missing something? void SubmitDetails(Object s, EventArgs e) { SqlConnection objConn = new SqlConnection(ConfigurationManager.AppSettings["ConnectionString"]); SqlCommand objCmd; objCmd = new SqlCommand( "INSERT INTO Member_Information (Name, Address_Line_1, Address_Line_2, Address_Line_3, Email_Address, Contact_Number, " + "Password, Name_Of_Bank, Account_Number, Sort_Code, Bank_Address_Line_1, Bank_Address_Line_2, Bank_Address_Line_3) " + "VALUES (@Name, @Address_Line_1, @Address_Line_2, @Address_Line_3, @Email_Address, @Contact_Number, " + "@Password, @Name_Of_Bank, @Account_Number, @Sort_Code, @Bank_Address_Line_1, @Bank_Address_Line_2, @Bank_Address_Line_3)", objConn); objCmd.Parameters.AddWithValue("@Name", txtName.Text); objCmd.Parameters.AddWithValue("@Address_Line_1", txtAL1.Text); objCmd.Parameters.AddWithValue("@Address_Line_2", txtAL2.Text); objCmd.Parameters.AddWithValue("@Address_Line_3", txtAL3.Text); objCmd.Parameters.AddWithValue("@Email_Address", txtEmail.Text); objCmd.Parameters.AddWithValue("@Contact_Number", txtContact.Text); objCmd.Parameters.AddWithValue("@Password", txtPassword.Text); objCmd.Parameters.AddWithValue("Name_Of_Bank", txtBank.Text); objCmd.Parameters.AddWithValue("Account_Number", txtAN.Text); objCmd.Parameters.AddWithValue("@Sort_Code", txtSort.Text); objCmd.Parameters.AddWithValue("@Bank_Address_Line_1", txtBA1.Text); objCmd.Parameters.AddWithValue("@Bank_Address_Line_2", txtBA2.Text); objCmd.Parameters.AddWithValue("@Bank_Address_Line_3", txtBA3.Text); objConn.Open(); objCmd.ExecuteNonQuery(); objConn.Close(); }

Hi, I'm relatively new to SQL and ASP.NET and I'm after some assistance to what I hope is an easily achievable goal.
I need to upload some files (.pdf, .doc, .jpg - whatever) to a directory on my webserver. Once this has been done, I'd like to write some data to an SQL Database Table that will contain information about these files in a datagrid (or something similar) along with a link to download them.
E.g I upload car.jpg which is located at /images/secure/car.jpg and is a photo of car. When a user logs in, they will be shown a datagrid which pulls information from said SQL database and in this datagrid will be something like:
Filename Description Link
car.jpg A pic of a car Download
If anyone is able to help me out with regards to linking to a file from an SQL dB it would be greatly appreciated, and if you require any further information just let me know :)
Ben.

I was all set to build some triggers on some modified date tables when in the last minute I found out that the application (built in C#) was controlling the after update trigger.
Is there a tool you can use in SSMS to see if there is a connection set up like this?

Can someone advise if there is a delay in data being written to the database following a tableadapter.update(datatable) command?
I save transactions which are subjected to the above and then a listview is updated to reflect them.
As I work through all is OK and the transactions appear in view.
I then run a backup through my app using a backup object to do this and this reports all OK
I then close the app and re-open and as as I am in debug the database is empty.
I perform a restore through my app using a restore object and selecting the backup file I created previoulsy which reports all OK
The retore procedure calls application.restart to allow the app to initialise to the restored data.
The problem is quite a bit of my data in missing from the restore as if the last block I did prior to backup never actaully made it to the database?
I also rememeber noting that at times when the update method is performed the actual timestamp on the physical databse is not updated....until I close the app and return to the designer?
So does this mean then prior to performing a backup I have to somehow force the app to ensure it has written all changes to the databse?
Thanks

Hey all Im trying to make a system in which users logged on can change their password. I dont want to use a grid view because that dosent give me the chance to let them put in their old password first for validation but now I need a way of takeing data out of the textbox with the new password and placeing it in to the field in a database.As I stand at the moment I have a data.dataview variable equal to an SQL Data Source with my query in it, bringing back a record from a users table with the users username, password and a field stating what type of user they are. It filters this by username which is stored as a session variable and username is the primary key. there is then an if statement checking that the string in the password field is equal to what the user has written in the old password box and if they match it uses the command:dv.Table.Rows(0)(1) = txtNewPassword.TextMsgBox("Password Successfully Changed", MsgBoxStyle.Information)When I run this the validation successfully checks the password is correct and then displays the message box saying the password is correct but it hasnt actually changed it. Somone I know told me that I need to use the command sqldatasource.update but I cant see where it fits in. Anyone got any ideas?

Hi Forum,
I am having a problem writing string values to my SQl database. I have the following code:
Dim pItemDescription As New SqlParameter("@itemdescription", o.ItemDescription)
cmdOrderDetails.Parameters.Add(pItemDescription)
o.Item Description returns the full string as a parameter but when it is written to the database it only writes the first letter in the database field. The column is set up as a VARCHAR with a a field length of 50 which is more than enough. Is there something I am doing wrong or missing out?
Thanks

Hi,
I have a data structure called 'Quote' which contains a number of different variables and controls ranging from text boxes, check boxes and radio buttons, i need to be able to read and write this from a database.
First I think a description of my overall project is needed:
Project Description
I have been given a brief that basically says: i have to create a programmed solution in VB to solve a problem. This problem can be anything we like, and I personally have chosen to create a program that manages quotes for building Log Cabins (this is very contrived and far from anything someone would do in the real world).
My solution will allow a generic user to create a quote (using a form with controls such as text boxes, check boxes, radio buttons) , and then save this to file. These users may then wish to load/edit this quote at a later date, from another form.
Whilst completing this project, i'll only have up to about 5 records (quotes) within the system, so i dont need the ability to store hundreds of records. And each record will be relatively short, with only about 10-15 data items within the data structure.
Also the Admin (or business owner in this case) need to be able to view all saved quotes in a presentable format, and edit them if needs be, from within this same program.
This solution does not need to be absolutely perfect and 100% efficiently coded, or have all the bells and whistles a real-world program would have. This is for an A level computing project by the way.
So basically, i need to be able to read from the database (to populate a Data Grid (i imagine this is best way?)) and so Admin can access any quote and edit it (editing is not vital, but viewing/printing is. Maybe i should stop at just viewing any quote?). Also i need generic users to be able to fill in the Edit Quote form and then save this data into the database.
And is a data structure really required for me to use a database?
I've never used databases in VB before (but have used them elsewhere, mainly Access) and so am completely new to this. Any help will be much appreciated.
Thanks

Hi,
I have created a package which uses the OLE DB Command as the target where I write the sql command to insert data into the table. The issue which I am facing is, while at the OLE DB COmmand , the package fails. I notices that it is not able to get the input columns which are mapped to the target columns.
The same package works fine when the target is on Oracle database or a SQL Server database.
For DB2, i have tried using the Microsoft OLE DB Driver for Db2, as the IBM DB2 Driver doesnt work for insert properly.
Any suggestion regarding this would be really helpful.
Thanks,
Manish

Hello!
I have created my self a person website in VS2008 using Linq and ahev downloaded a copy of sql express to use as my database when working on it at home.
I have just noticed, now I am trying to upload it to a server that my sql express is automatically creating the database in my app_data folder, this is causing me problems, as I don't want it to do this. I want it to be able to point it at a full version of SQL server.
Is there some setting I have missed? Of how can I stop tis automatic creation of the database?
Thanks
Bex

Hi I am new at this.
I have a little program written in C# in asp.net. The program basically accesses a database and stores new records. The database is supposedly already attached to MSDE so I am able to see the tables of the database inside asp.net. I can click on the individual slots of the table and modify the datas manually. However, I want to connect to the database from my C# program and be able to input data into the database via the website that the C# program produces. After I type in the data into the website and click the submit button on the website, I get an error page that says this:
Login failed for user 'sa'
the line of code thats causing this error is:
con = new SqlConnection("data source=(local)\NetSdk; initial catalog=Friends; user id=sa");
Why is it not able to connect to the database?

I used VWD 2005 Express to create my web application (that uses a sql 2005 database), and now I'm trying to deploy it. I was to understand that all I had to do was to upload all my files to the root folder and the web host's server (webhost4life.com). However, they require me to upload the sql 2005 db to a seperate sql server using a control panel that is very clunky. Does anyone know how to upload the sql 2005 db to the host server or an online tutorial where I could go to learn? Thanks for the help!

I am doing one of the Microsoft virtual labs "Creating ASP.NET Web Applications with C# - Part 2" using Visual Web Developer Express. I am trying to fill a gridview with database information, but it gives me the error "An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)".This is on the local machine that I am executing the code. public void BindGrid(string sortfield)
{
//Create DataAdapter to fetch data from Prodcuts table
SqlDataAdapter myCommand = new SqlDataAdapter("select * from Products", myConnection);
//Create dataset and fill it with Product data
DataSet ds = new DataSet();
myCommand.Fill(ds, "Products");
//Bind Product data to Datagrid
DataView Source = ds.Tables["Products"].DefaultView;
Source.Sort = sortfield;
dgProducts.DataSource = Source;
dgProducts.DataBind();
} It stops on the line "myCommand.Fill(ds, "Products"); and points out the error mentioned earlier. I am not sure what to do...any help would be greatly appreciated, thanks in advance, and I apologize as well if I have not pointed out enough information.

Hi all, this has been bothering me for a few days now so i thought id better get some good advice!
I am going through the process of exporting a SQL Server 2005 DB to my hosting company for the first time. Initially I tried using SQL Server Management Studio to "Export" the DB, which has all of the membership functionality (by runnung aspnet_regsql.exe) and a few extra tables - nothing too complicated.
Exporting with SQL SMS did not seem to copy my stored procedures accross and this gave me problems.
I then tried SQL Server Database Publishing Wizard - as recommended by this post: http://weblogs.asp.net/scottgu/archive/2007/01/11/tip-trick-how-to-upload-a-sql-file-to-a-hoster-and-execute-it-to-deploy-a-sql-database.aspx
So this is my process:
1. set up empty DB on hosting server2. get admin to allow dbo permissions on this DB3. open SQL SDPW and create a script which will create an exact copy of my local DB4. run the script on my new empty Db on server...
when i do this i get the following errors:
Msg 208, Level 16, State 1, Procedure vw_aspnet_Users, Line 3Invalid object name 'dbo.aspnet_Users'.Msg 208, Level 16, State 1, Procedure vw_aspnet_MembershipUsers, Line 3Invalid object name 'dbo.aspnet_Membership'.Msg 208, Level 16, State 1, Procedure vw_aspnet_Profiles, Line 3Invalid object name 'dbo.aspnet_Profile'.Msg 208, Level 16, State 1, Procedure vw_aspnet_UsersInRoles, Line 3Invalid object name 'dbo.aspnet_UsersInRoles'.Msg 208, Level 16, State 1, Procedure vw_aspnet_WebPartState_User, Line 3Invalid object name 'dbo.aspnet_PersonalizationPerUser'.
When i look at the DB hosted on the server, it seems that all of my stored procedures are there. One thing I noticed was that some of my "Views" were in the "Tables" folder (i dont know if this matters)The result that this is having is that I do not get any errors, but the queries on my page where i reference one of my views (like vw_aspnet_MembershipUsers), the latest records are not appearing.I think that somehow my stored procedures are not referencing the correct views and tables maybe?Anyway - if anyone has come across this, please help me out (even if its just to say ive done something stupid )

First off, I am fairly new to sql.
I've created an sql database in VB express, created some tables, and entered some data in those tables. My problem now lies with actually using that data. What i'd like to do is have a Sub use the database's data and fill in a series of variables. Right now i have the Sub using an Excel file to assign the information, looks like this:
Public Sub CharStatDefault() 'loads each character's default stats
CharSheet = xlBook.Worksheets(2)
P.initialize()
For excelInt = 1 To 22
P.C(excelInt).Initialize()
With P.C(excelInt)
.Vit = CharSheet.Range("AC" & excelInt).Value
.Phy = CharSheet.Range("AD" & excelInt).Value
.Mag = CharSheet.Range("AE" & excelInt).Value
.Off = CharSheet.Range("AF" & excelInt).Value
.Def = CharSheet.Range("AG" & excelInt).Value
.Agl = CharSheet.Range("AH" & excelInt).Value
End Sub
So basically i want to change the CharSheet.Range("XX" & excelInt).Value to something that utilizes the data from my database.

Hello,
Is there any ability to do database-level triggers in SQL 2000? I have a SQL 2000 database, and I was asked if we could create a trigger that whenever anyone touches the data in a database, to create an entry in an event log? If not, I have a main table I can put a trigger on; however, my question is how do you write to a file in a trigger as well?
Thanks.

Hi All,
I have seen some different behaviors when I am writing SQL Server compact edition Database file into SD Memory card or any user removable storage media.
The following Steps for reproducing these behaviors.
1. Set your database location is in the SD Memory card.
2. Create a database and establish session.
3. Writing first record into the database is done
4. Remove your SD card manually from the system
5. Try to write a Second record into the database
6. You will get the error from this "SqlCeWriteRecordProps" API call - This is fine.
7. Put your SD card back into the system.
8. Writing Second record again into the database is done - This is fine.
So far the behaviors are good after that
9. Remove your SD card manually from the system again
10. Try to write a Third record into the database
11. You will suppose to get the error from this "SqlCeWriteRecordProps" API call but you won€™t get that error €“ I don€™t know why?
12. Then Try to write a Forth record into the database
13. You won't get any error from the API call "SqlCeWriteRecordProps" and return status is success.
14. Now put your SD card back into the system.
15. Then write Fifth record but this time its writing record Third, Fourth and Fifth into the database.
Note:
I am clearing (means Free) my record structure everything after calling this function "SqlCeWriteRecordProps". So I don€™t know why its wring Third, fourth and fifth record into the database.
Please Let me know your feedback.
Thanks,
Rajendran

Is there a way I can write a query to dynamically select a database table. That is, instead of having a variable for a certain column like customerId which would be €ścustomerID = @customerID€? I want to use the variable to select the table. I assume I may have to use a stored procedure but I am unclear as to how this would be coded.
Thanks

I would like to know how to (if it is at all possible) in SQL (or even ADO) to retrieve all the data concerning database X's
a) Tables
b) Tables column names
c) Tables column's data types
I don't want to use the doa.tabledefs object.. .i would prefer to do it in SQL, but using ADO objects (since I am developing stuff in VB) would be ok too.
Please Help.. i have been going crazy trying to find anything useful.. email me back please!
Thanks,
Matt

Hello everyone.
Pretty new to SQL Server and i've run into some trouble with something I am attempting to do.
Basically, we imported one of our databases on one of our SQL Servers to a new sql server that we just setup. That went ok with no problems. The DB is now in the new SQL Server.
Now, we need to copy the contents of a second DB from the original server into this new sql server DB. For reference:
We imported a DB Called: siebeldb
We want to import/overwrite another DB into that same DB. We backedup the DB and moved the file to the new SQL server.
So:
Import/Restore: sbprd01(a backup file) into siebeldb
I hope that makes sense.
I have the following command that I am trying to execute in the SQL Query analyzer:
RESTORE DATABASE siebeldb
FROM DISK='C:Documents and SettingsAdministratorDesktopsiebelprddb092509.bak'
WITH MOVE 'siebelprddb_Data'
TO 'C:Program FilesMicrosoft SQL ServerMSSQLDatasiebeldb_Data.mdf',
MOVE 'siebelprddb_Log'
TO 'C:Program FilesMicrosoft SQL ServerMSSQLDatasiebeldb_Log.mdf',
REPLACE
It is running right now, but seems to be running into errors. I just added the 'REPLACE' option according to the t-sql reference guide.
Does my script look ok? Am I doing anything wrong?
Thanks,.

Hey everyone I've got this question that has me stuck for the last few days but its an important part of my website.....What I am trying to do is basicly have a user be able to upload a file, have that uploaded file plus some other info automaticly display on other parts of my site, and have a different user eventually be able to download that file....I have thought about allowing the file upload as a BLOB but still cannot find a proper way to execute this using VB, plus I have heard that this way of doing it is not reccommeneded cause databases were not designed to store large files like this, lots of articles recommened having the file upload to a Folder on your server then get the binary data for the file that can be placed in a database to refrence that particular file.....Well this also proves to be a lot harder then said here is what I got so far (written in C#) protected void UploadBtn_Click(object sender, EventArgs e)
{
if (FileUpLoad1.HasFile)
{
FileUpLoad1.SaveAs(@"C:Documents and SettingsAdamMy DocumentsVisual Studio 2005ProjectsWebsiteFiles" + FileUpLoad1.FileName);
Label1.Text = "File Uploaded: " + FileUpLoad1.FileName;
}
else
{
Label1.Text = "No File Uploaded.";
}
}
and here is the asp part of the code that goes with it<asp:FileUpLoad id="FileUpLoad1" runat="server" />
<asp:Button id="UploadBtn" Text="Upload File" OnClick="UploadBtn_Click" runat="server" Width="105px" />
<asp:Label ID="Label1" runat="server" Text=""></asp:Label>
Now from what I know is I need to get the binary of the file which I have read you can do with the Page.Request.Files statement but again not sure how I would impliment this. Does anyone have any suggestions on which way I should take when dealing with this should I try and just use the BLOB method or use the binary refrence method? and if so how would I impliment this, heck even some good tutorials on the subject would be great... Thanks.....Adam
