View 4 Replies,I am creating a database where each record is required to have a twin record in the database.These is a type a value and a type b value and both must be present for the record to be valid.
Customer_ID, Order_Type, Product_Code
54, a, 00345
54, b, 00356
Is this something that would have to be done programmatically, or is it possible to create a constraint of some sort to ensure this?
Hi guys, may I know is it possible to create an update trigger like this ? Assuming there are two database, database A and database B and both are having same tables called 'Payments' table. I would like to update the Payments records on database A automatically after Payments records on database B had been updated. I can't use replication because both tables might having different records and some records are the same. Hope can get any assistance here, thank you.

I was stuck when update database using SqlDataAdapter. I have several textboxes in my webform1. When wepform1 is loaded, they will display user's information. The user can only input content in two textboxes. When user clicks the update button, I hope to update this record in SQL Server 2000 database. However, the program didn't work. There was no error message reported but when I stepped into the code, I found out that dataadapter's update method didn't succeed. I got 0 rows affected. Can I get some advice from someone ?
Here is the code:

SqlDataAdapter UpdateDa = new SqlDataAdapter("Select * from Table1",SqlConnection1);
UpdateDa.UpdateCommand = new SqlCommand(StrUpdateCmd, SqlConnection1);
//Add parameters of update command.
SqlParameter prm1 = UpdateDa.UpdateCommand.Parameters.Add("@Hphone",SqlDbType.NVarChar, 16);
prm1.Value = txtHphone.Text ;
SqlParameter prm2 = UpdateDa.UpdateCommand.Parameters.Add("@Cphone",SqlDbType.NVarChar, 16);

I has a strange question.My company is using a old system with Win NT 4.0 Server + MS SQL 7.0.The system is busy and handle a lot of SELECTs and INSERTs all the time.Sometimes, some transactions are blocked by some other transactions.For those INSERT transactions, we usually call a stored procedure and passparameters in to do the INSERT, at the end of the INSERT stored procedure,we always check @@ERROR = 0 and retrieve the @@IDENTITY (it is usually theauto number primary key) to confirm the INSERT is success. But the strangethings is, sometimes, @@ERROR is equals to 0 and I can get a value from@@IDENTITY but when I fetch the record by the primary key (the value of@@IDENTITY) it returns nothing!! The record is disappear and the primarykey is skipped! I found that this happens usually when the INSERT executeat the time when some other transactions are blocking. Anyone knows why therecord is disappear while @ERROR = 0 and the stored procedure can returnvalue from @@IDENTITY?? Anyone has such case happen in their server aswell? Please tell me some solutions on how to solve this, thank you x10000000 times.

Hello, i currently have a gridview component displaying data from a SQLSERVER2005 database. I have created an 'edit' hyperlink on each record so that when pressed, the primary key of a record is sent in the querystring to another page when pressed. example http://localhost/Prog/EditAppointment.aspx?AppointmentId=1
In the edit page, i have dragged and dropped a sqldatasource that contains the select and update statements. i would now like to use textboxes and dropdowns to display the data for the particular record selected (in this case appointmentid=1). however i dont want to use a formview or automated component, just to drag and drop the textboxes myself. how do i bind the textboxes in the HTML code to the data from the select statement? My current select parameters look as follows.
<SelectParameters>
<asp:QueryStringParameter Name="AppointmentId" QueryStringField="AppointmentId" Type="Int32" />
<asp:ControlParameter ControlID="Textbox1" Name="PatientNo" PropertyName="Text" Type="String" />
</SelectParameters>
Perhaps there is an error in my select parameters or does the problem lay elsewhere? Any help would be appreicated.
Thanks,
James.
Hi i have a very annying problem that i cant seem to solve by myself. I have developed a content managment system for a webpage where people can manage the page. It's almost done except for the fact that i cant seem to delete records from my sql express database.
To access the database i use an sql login in my code to delete witchever record is retrived from a querystring in the URL field. Below is a sample of my delete code when a button is pressed. protected void ButtonDelete_Click(object sender, EventArgs e)
{
string dID = Request.QueryString["dID"];
string myConnectionString = @"Data Source=SRVWEBSQLEXPRESS;Initial Catalog=se;User ID=xx;Password=xx";
SqlConnection myConnection = new SqlConnection(myConnectionString);
string myDeleteQuery = "DELETE FROM drift WHERE dID = @dID";
SqlCommand myCommand = new SqlCommand(myDeleteQuery);
myCommand.Parameters.AddWithValue("dID", dID);
myCommand.Connection = myConnection;
myConnection.Open();
myCommand.ExecuteNonQuery();
myCommand.Connection.Close();
Response.Redirect("list.aspx");
}
When the i run the code on my development machine located at 10.12.0.80 and the server is located at 10.12.1.65 and this is where the databse is located. The strangest thing is that when i press my deletebutton while debugging in VS2008 on my devmachine the record is deleted! BUT when i run the code live on the server i get an error. See the below log file taken from the windows 2003 server application log.

Got a question here and as I am no expert programmer, this should be easy for you gurus. I have this fairly generic code I've created where I return data from an SQL table in a DataList control. I want to take it to the next level and return only the last record in the table, but I am unsure of how to do that. Perhaps I shouldn't even be using a DataList control, I'm not sure.
View 2 Replies View RelatedIn my asp.net page when I run a query against the database the datagrid get populated with only the records that starts with the first letter for example A good day. But none of the records that starts like this "A fine day" or "A nice day" displays in the datagrid. I tried to replace the Double Quote but it still returns only the records without " quotes. My query looks like this:
Dim queryString As String = "SELECT [Articles].[AN], [Articles].[Department], [Articles].[ArticleHeading], [Articles].[AccessLevel], [Articles].[Status] FROM [Articles] WHERE (([Articles].[AccessLevel] <> 'SysAdmin') AND ([Articles].[Status] = 'Enable') AND (REPLACE([Articles].[ArticleHeading], 'chr(34)', '')) like @ArticleHeading) ORDER BY [Articles].[ArticleHeading]"
I have a SQL database that gets populated by another program. Is there a way to determine when a new record is added to that database?

Can I do something like this in RS -
I would like to call a function in a calculated field like
=code.GetNHW(Fields!id1.Value,Fields!date1.Value)
where the GetNHW() function would return a double value based on some conditions-
The code I would like to write in Code window-
Public Function GetNHW(ByVal ID As Integer, ByVal attDate As Date) As Double
Dim dsDTConfig As New DataSet
Dim NHW As Double
dsDTConfig = GetDS("tblEmployee_DailyTimingsConfig", "id=" & ID & " and '" & attDate & "' between configStartDate and configExpiryDate", False)
If dsDTConfig.Tables(0).Rows(0)("allowUnscheduledBreaks") = True Then
NHW = 0.01
ElseIf dsDTConfig.Tables(0).Rows(0)("allowUnscheduledBreaks") = False Then
NHW = 0.05
End If
Return NHW
End Function
What I am looking for is - I would want to get the record(dataset) within the function from the database
and based on the values got, I would check few conditions and calculate NHW.

Let's imagine some situation in MS SQL 2005:
Table t_sample with single column SampleString of type varchar(200). If to this column will be inserted value containing 4 chars, real record (not column) size in database would be 4 or 200? In other words: do MS SQL 2005 records have always constant size (total size of all columns max sizes) or real size of record depends on actual size of inserted data?

View 2 Replies View RelatedI don't work much with the back end of software development so there is a lot about SQL Server I do not know.
We are building a database. The database will have about 10 tables in it. 3 of these tables will probably have a huge amount of data in them. Specifically each one of the 3 tables will each have about a half a million database records in it. Each record is about 100 characters max in length.(Im am including numbers as characters and summing the individual columns/fields to come up with 100).
Will a SQL server database table with A half a million records in it be possible? We have tried to normalize the database to cut down on the size of the table but it all comes out to about a half a million records per table.
Any help is deeply appreciated.
