SQL Server :: SqlDataAdapter Update Returns 0 Records?

Jan 25, 2011

using ASP.NET 2.0 SqlDataAdapter update returns 0 records. I have a simple application that stores Passenger's ticket info in a sql database.

when a user clicks "Create Reservation" I add a Passenger Information (name, destination, PNR) to dataset
and save dataset in ViewState.

Then when user clicks update, I pull the dataset from viewState and try to update database. The update is returning 0. what i am doing incorrectly?

protected void btn_CreateReservation_Click(object sender, EventArgs e)
{
DataRow dr ;
dr = dt.NewRow();
dr["Name"] = txtBox_Name.Text; dr["Destination"] = txtBox_Destination.Text;
dr["PNR"] = Convert.ToInt32(txtbox_PNR.Text); dt.Rows.Add(dr);
dt.AcceptChanges();
ViewState["MyTable"] = dsPassengers;

[Code]....

SQL Server :: Update Multiple Records - Subquery Returns More Than 1 Row

Jan 5, 2011

I have a table line (ID, LineNo, LineName) having values as :

1, 1, <blank>
2, 2, <blank>
3, 3, <blank>

ID is PK with Auto-Increment and LinNo(I am manually incrementing through ASP.Net Page while record insertion) Now i have to write a query such that it updates LineName column from line table which is blank(as shown above) with values from table linet(linenamet) having values as :

a
b
c

My trial query is :
update line set LineName = (select linenamet from linet);

It gives ERROR as : Subquery returns more than 1 row
Expected Result : After Updation it should show line table as :
1, 1, a
2, 2, b
3, 3, c

SQL Server :: Update Statement Not Updating Records And Returns No Errors?

Sep 16, 2010

I am running an Update statement against an SQL database on server 2008. The update runs but does not update the record, but returns no errors.The database is part of a commercial help desk package called TrackIt 8.5 which was just a fresh install on a new web server and a new sql server. The update is running from a web form we use to automatically create active directory accounts. After the account is created the web form closes out the work order in the Trackit db. This was working fine when the system was running on Server 2003 and SQL server 2005. Running Trackit version 7.02.The login use to access the database has full permissions to read and write to the database, just as it did on the old server which never had an issue updating. Odd thing is, if I log onto the SQL server and make a change to any single field in that record. I can then run the web form and it updates the record normally.

C# - SqlDataAdapter.Fill(DataTable) Returns No Rows?

Feb 7, 2011

I am trying to use a SqlDataAdapter to fill a DataTable, which I use as a data source to a DataGrid. The query is fine, at least when I run it manually in SSMSE. When I do the fill operation, the table gets the right columns, but no rows. The most frustrating part of this is that the code is identical (with a different query) on a different page. I cannot post the query, but my initialization code looks like this:

SqlCommand areaDAC = new SqlCommand (areaQuery, connection);
areaDAC.Parameters.Add (new SqlParameter ("@param", System.Data.SqlDbType.NVarChar, 50));
m_areaDataAdapter = new SqlDataAdapter (areaDAC);

Then to use it:

m_areaDataAdapter.SelectCommand.Parameters["@param"].Value = "Filter Val";
DataTable table = new DataTable ();
m_areaDataAdapter.Fill (table);

At this point, table has the right number of columns and no rows. I know the parameters are being added correctly, I know that data exists for the given query.

Update (as provided by Nik in a comment):

DataSource Controls :: How To Add Rows To Datatable And Use Sqldataadapter Update Method

Jan 24, 2010

I'm trying to add new rows to a data table and then use the sqldataadapter update method bu fund some problems. First, I written this code:

Excuse me but the most part of variable are in italian, however I think it is possible to understand how does it work. If I execute this code I obtain this error:

System.InvalidOperationException: Update requires a valid InsertCommand when passed DataRow collection with new rows.

After this I added these lines of code just above the last line:

SqlCommandBuilder cb = new SqlCommandBuilder(adapter);
adapter.InsertCommand = cb.GetInsertCommand;

and I obtained this error:

Cannot convert method group 'GetInsertCommand' to non-delegate type 'System.Data.SqlClient.SqlCommand'. Did you intend to invoke the method?

C# - SubSonic .Paged() Query Returns Duplicate Records

Feb 8, 2011

Using a SubSonic (2.2) SqlQuery object, I am querying a view that contains distinct rows from another table. The results of the query, however, contain multiple rows for certain rows in the view. It appears to be because of a join on a temporary table in the query generated to achieve paging. How can I avoid this duplication of rows?

Bonus points: I have to use the view because SubSonic can't do .Paged() and .Distinct() at the same time. Why not?

Web Forms :: Class Method Returns Incorrect Records

Apr 27, 2016

This is the query I am running in DB:

select UM.USER_NAME, RM.ROLE_ID, RM.ROLE_NAME
FROM [MICommonDB].[dbo].[ROLE_USER_MAPPING] as RUM
join [MICommonDB].[dbo].[ROLE_MASTER] as RM ON RM.ROLE_ID=RUM.ROLE_ID
join [MICommonDB].[dbo].[USER_MASTER] UM ON UM.USER_ID = RUM.USER_ID
where UM.USER_NAME='useruser'
which is giving me proper result(i.e., 2 records) when running in SQL server.

Now I have created below method in a class with same query (I am calling this method inside Controller):

public IEnumerable<RoleUserDO> getRoleNameByUserName(string userName)
{
IEnumerable<RoleUserDO> strResult = null;

strResult = (from RUM in oDBContext.ROLE_USER_MAPPING

[CODE]..

but it returns only 1 record instead of 2 records(when compared with DB query)

SQL Server :: Timeout When Calling SqlDataAdapter.Fill (DataSet)?

Sep 13, 2010

This issue has stumped me for a while. Hopefully someone here can give me some insight.

When my site runs the following code it works just fine 99% of the time.

[Code]....

The command is calling a SQL Server 2005 stored procedure that takes 20 parameters and returns 6 tables of about 5-50 rows each. The paramters are all NVARCHAR, INT, or BIT data types. Only one of the parameters is Input/Output. There is a total of about 100 rows returned. Normally this takes a fraction of a second, but for some queries, it times out after 30 seconds.

When I run the exact same query in the Management Studio query window it takes 1 second.

what I can do to get the same performance from .Net as I am getting from Management Studio?

Merge The Records From The Database On The Local Machine With The Records On The Remote Server?

Mar 31, 2010

The website is over half way done and the functionality for the blog is (except for adding posts) is already implemented and working correctlyI have a SQLExpress 2008 backendBlog posts are rendered on the page with full HTML markup within a label control.

All of the above is done and working. Though I am essentially new to creating websites with ASP.NET, CSS and SQL, I am sure that I could simply carry on and make a login page with some controls that would allow me to add records (blog posts) directly to the database on the host server. However, I am fearful of doing this because I know that malicious code can be passed in this way. Also, because of my lack of knowledge, the only way that I know of to pass the code from a control to the database is to disable validation for the page the control is on. Without a doubt I do not want to do that.

So what are my options for getting blog posts into the database? Is it safest for me to fully create the post in html and update a copy of the database that resides on my local machine? If I do it this way, how can I merge the records from the database on the local machine with the records on the remote server?

Server.TransferRequest Returns Blank Page On Specific Server?

Jun 17, 2010

I have a webapplication based on MonoRail, where we utilize the routing feature from MonoRail. On the first request after the application has started, the routing isn't initialized. To circumvent this, I have the following code in Application_OnError():

public virtual void Application_OnError()
{
if ( // identified as routing error )
Server.TransferRequest( Context.Request.RawUrl, false );
return;
}

Problem beeing that on our development server (which runs server 2008 R2, with IIS 7.5 and .NET 3.5) returns a blank page without headers, but on my workstation (which runs win7, IIS 7.5 and .NET 3.5) it works fine.

What could be the cause of this? If the code in Application_OnError() throws an exception, what would be the expected output?

I have verified the following:

The access-log shows one entry, I'm not sure if a TransferRequest would show up as a second entry when invoked successfullyThe application actually do some work according to my internal logs, and it doesn't die since a subsequent requests works flawlessly (because routing will be active)

Can Update Some Records In A Database Correctly

Mar 14, 2011

I have an ASP.NET web form application that on the server side I need to know the user's identity. I do not need to impersonate the user. I just need their username so I can update some records in a database correctly.When the request is processed I have the following line of code:

string userName = Request.LogonUserIdentity.Name;
if(true == string.IsNullOrEmpty(userName))
{
logger.logwarning("missing username");
}
else
{
logger.loginfo("update by {0}", userName);
}

In my development & QA environment this works perfectly - I see the userName in the log file and all of the database records have the lastModifiedBy field filled in correctly. However, when we go to production - userName is an empty string.
