SqlDecimal total = 0;
SqlConnection conn = new SqlConnection("Context Connection=true");
SqlCommand cmd = new SqlCommand(@"SELECT column1, column2, column3
FROM table ", conn);
conn.Open();
SqlDataReader rdr = cmd.ExecuteReader();
while (rdr.Read())
{
if (rdr.GetSqlString(1) == "01")
{
// ADD the current record to a temp list
total = total + rdr.GetSqlDecimal(2);
}
}
SqlContext.Pipe.Send(total.ToString());
// RETURN the temp list
rdr.Close();

Hi - I'm using Session variables to store information (sort of webshop).
The sessions are a mix of the usual straightforward strings, wich are no problem - but I also have a DataTable which I store in a session variable, and I also have an array, which I store in a session variable eg. session("day")(x) where x is the item in the array.
I want to give my users the ability to store the items they've selected in my database, but have no idea of what type of field I should use for the datatable and array session variable. Should I use a TEXT field, or is there another more appropriate one'?
I'm using SQL Server 2000.
Thanks for any help,

How does one pass into a Stored Procedure an array of numbers to be used in an IN clause? If I pass "1,2" in a VARCHAR, the stored procedure sees only the first number (1 in this case).
I'm using VB and ADO.NET, but I don't know how to set up the stored procedure for an array. Is there a parsing function to do this?
CREATE PROCEDURE TestInClause( @TeamList VARCHAR)ASSELECT Name FROM Teams WHERE TeamID IN (@TeamList); /* sees only 1st number */GO
I€™ve inherited a project from one of the guys on our team who will be out sick for a while. He developed two for marshaling data between System.Drawing.Image and System.Byte(). He€™s storing the byte array data in a database image field.
I€™ve retrieved the byte array data from his database image fields and have successfully converted them to images using his ConvertByteArrayToImage method below. I have also converted and image to a byte array with his ConvertImageToByteArray method below and succfully stored the data in a database image field. However, when I retrieve the byte array data that I stored in the database the last line in his ConvertByteArrayToImage method throws an exception (Parameter is not valid). I€™ve not been able to find a working copy of his code that€™s storing the byte array data. Does anyone see anything I€™m overlooking?

Hi,
I want to store the System::StartTime in my Integration Table Log. Please guide how can I use this in my Execute SQL Task Block. I write this SQL Statement:

Please help how to write this System Variable value in to that table.

I have recently designed and built my first database using SQL server 2005 express. I have included an image (BLOB) column in one of the database tables. This is a bad idea according to some experts, and some say it is OK!
I am currently carrying out a trial with just 3 pictures via Visual Basic 2005 express forms, and there is no problem so far as the images are displayed for each record. But I anticipate between 300 - 1000 images for the table, and this could pose real problems for SQL server 2005 express and Visual Basic 2005 express, I guess.
I have just been reading that the cost of storing large images in the database is too high! I have also read it's better to store images (BLOB) into the file system because it is cheaper to store them no matter how many there are.
But the question is how I can reference an image in this path: C:PictureProductGrocery 0052745.jpg in the database table, so that when I select a record Visual Basic 2005 forms the image is displayed accordingly, similar as when stored directly in the database table? Your help very much appreciated.

I am using Reporting Services 2005. One of my reports is getting the following error when I try to export to Excel. It will export to .CSV though.

I have a stored procedure that has a paramter that accepts a string of values. At the user interface, I use a StringBuilder to concatenate the values (2,4,34,35,etc.) I would send these value to the stored procedure. The problem is that the stored procedure doesn't allow it to be query with the parameter because the Fieldname, "Officer_UID" is an integer data type, which can't be query against parameter string type.
What would I need to do to convert it to an Integer array?
@OfficerIDs as varchar(200)
Select Officer_UID From Officers Where Officer_UID in (@OfficerIDs)
Thanks

Ok guys, I am trying to install Sql server 2005 on Vista but I am still stuck with this warning message in the System Configuration Check during Sql server 2K5 installation :
SQL Server Edition Operating System Compatibility (Warning)
Messages
* SQL Server Edition Operating System Compatibility
* Some components of this edition of SQL Server are not supported on this operating system. For details, see 'Hardware and Software Requirements for Installing SQL Server 2005' in Microsoft SQL Server Books Online.
Now, I know I need to install SP2 but how the hell I am going to install SP2 if Sql server 2005 doesn't install any of the components including Sql server Database services, Analysus services, Reporting integration services( only the workstation component is available for installation)?
Any work around for this issue?
P.S.: I didn't install VS.NET 2005 yet, can this solve the problem?
Thanks.

Hi,I have a few things on my databases which seem to be neither true systemobjects or user objects - notably a table called 'dtproperties' (createdby Enterprise manager as I understand, relating to relationship graphingor something) and some stored procs begining with "dt_" (some kind ofsource control stuff, possible visual studio related). These show up whenI use"exec sp_help 'databaseName'"but not in Ent. Mgr. or in Query Analyzer's object browser, and also notin a third party tool I use called AdeptSQL. I am wondering how thosetools know to differentiate between these types of quasi-system objects,and my real user data. (This is for the purpose of a customized schemagenerator I am writing). I'd prefer to determine this info with systemstored procs (ie sp_help, sp_helptex, sp_...etc) but will dip into thesystem tables if needed.Thanks,Dave

I have two CheckBoxList controls. One CheckBoxList is a group of area codes as they apply to our customers, and the second CheckBoxList is a group of categories of those customers. The code below works fine with either CheckBoxList as a standalone (this code applies to the Area Codes selection), but what I need is the VB code to combine the choices a user makes in both CheckBoxLists. Is this where parameterized SQL comes into play? Or can I/should I use an array statement to combine both CheckBoxList choices? Sometimes a user will select nothing in one CBL and a few choices in the other, or vice versa, or a handful of choices in both CBLs, so that they might want only customers in, say two area codes and then only the selected categories of those area codes. Need help on this one, thanks...Protected Sub btn_CustomerSearchCombine_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btn_CustomerSearchCombine.Click Dim ACSelections As Boolean = False Dim ACItem As ListItem For Each ACItem In cbl_CustomerSearchAREA.Items If ACItem.Selected Then ACSelections = True End If Next If ACSelections = True Then Dim ACSqlString As String ACSqlString = "SELECT Customers.CustomerID, Customers.CustomerName, Customers.CategoryID, Customers.EstHours, Customers.Locality, Categories.Category FROM Customers INNER JOIN Categories ON Customers.CategoryID = Categories.CategoryID WHERE " For Each ACItem In cbl_CustomerSearchAREA.Items If ACItem.Selected Then ACSqlString &= "Customers.AreaCodeID = '" & ACItem.Value & "' OR " End If Next ACSqlString = Left(ACSqlString, Len(ACSqlString) - 4) ACSqlString &= "ORDER By Customers.CustomerName" sql_CustomerSearchGrid.SelectCommand = ACSqlString End IfEnd Sub

Hi all,
My Issue is the next thing:
I have a table filled with contracts
I have Stoc that checks if contract has expired
If I start the Stoc I must give it the contractnumber with it like:
SP_expired 8
This works fine but now I want that the Stoc checks all the contracts by just starting the Stoc.
I don't really know how to do this, I have thinking about using an array.
But don't have an idea where to start....
Thnx in advance
