How To Read A Set Of Rows Into Session Variables? C#
Oct 23, 2007
Hello ASP.NET C# and SQL gurus
I want to read the results of a set of rows into session variables -- how is it possible?
Let me try explain. I have a query which returns multiple rows, e.g. the following query
SELECT PROFILE_ID, PROFILE_NAME FROM USER_PROFILES returns 5 rows i.e 5 sets of profile_ids and profile_names.
Now, I want to capture these and store them in session variables thus.
Session["PROFILEID_1"] =
Session["PROFILEID_2"] =
Session["PROFILEID_3"] =
Session["PROFILEID_4"] =
Session["PROFILEID_5"] =
Session["PROFILENAME_1"] =
Session["PROFILENAME_2"] =
Session["PROFILENAME_3"] =
Session["PROFILENAME_4"] =
Session["PROFILENAME_5"] =
Thanks in advance!

Hi,
I am using a Script Component and I have a Read/Write Variable varStatusCase (as assigned in the Custom Properties of my Script Component). I used this inside my script to get a specific value. However, when I ran it I get this error:
The collection of variables locked for read and write access is not available outside of PostExecute.
How do I repair this?
Thanks,

Hello Guys,
in SSIS I want to get a set of data and do some modifications on it before I insert it into the destinatipn. So far so good. Some of the modifications will include comparisions between two columns and if certain field is NULL then I want to get the value from the other one I was comparing to. When using conditional splits, I only get the rows to be redirected so that I can do whatever next. However, I want like use the variables as a storage so that I can put the value of one of the two columns in this variable which will be actually loaded into the destination finally. Any help?
Thanks

Hi all, first post, and I am desperate.
I have a SqlDataSource with a Select, Update and Delete command. From what I understand, scalar variables should be read automatically from the GridView's BoundField columns when it executes a command on it. Here is my code:
<asp:GridView
ID="teamGrid"
EmptyDataText="n/a"
DataKeyNames="TeamId"
AutoGenerateColumns="false"
DataSourceID="teamSource"
OnRowEditing="validateEdit"
OnRowDeleting="validateDelete"
runat="server">
<Columns>
<asp:CheckBoxField DataField="TeamApproved" HeaderText="Approved" />
<asp:BoundField DataField="TeamName" HeaderText="Team Name" />
<asp:TemplateField HeaderText="City">
<ItemTemplate>
<asp:Label runat="server"><%# Eval("City") %></asp:Label>, <asp:Label runat="server"><%# Eval("ProvinceCode") %></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:BoundField DataField="RequestedDivision" HeaderText="Division Req." ControlStyle-Width="60px" />
<asp:BoundField DataField="DivisionCode" HeaderText="Assigned Division" ControlStyle-Width="60px" ConvertEmptyStringToNull="true" NullDisplayText="n/a" />
<asp:BoundField DataField="DivisionNumber" HeaderText="Division Number" ControlStyle-Width="60px" ConvertEmptyStringToNull="true" NullDisplayText="n/a" />
<asp:BoundField DataField="Password" HeaderText="Password" ConvertEmptyStringToNull="true" NullDisplayText="n/a" />
<asp:CheckBoxField DataField="Paid" HeaderText="Paid" />
<asp:HyperLinkField Text="view players" ItemStyle-Width="70px" ItemStyle-HorizontalAlign="Center" DataNavigateUrlFields="TeamId" DataNavigateUrlFormatString="viewTeamPlayers.aspx?teamId={0}" ShowHeader="false" />
<asp:CommandField ItemStyle-HorizontalAlign="Center" ItemStyle-Width="30px" ButtonType="Link" EditText="edit" ShowEditButton="true" ShowHeader="false" />
<asp:TemplateField ShowHeader="False" ItemStyle-HorizontalAlign="Center" ItemStyle-Width="30px">
<ItemTemplate>
<asp:LinkButton runat="server" CausesValidation="False" CommandName="Delete" OnClientClick='return confirm("Deleting this team will also delete the players. Are you sure you wish to continue?");' Text="delete" />
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
<asp:SqlDataSource
ID="teamSource"
ConnectionString="<%$ ConnectionStrings:MB %>"
SelectCommand="SELECT TeamId, TeamName, ProvinceCode, City, DivisionCode, DivisionNumber, TeamApproved, RequestedDivision, Paid, Password, CaptainId, Player2Id, Player3Id, Player4Id FROM [Team]"
UpdateCommand="UPDATE [Team] SET TeamName = @TeamName, DivisionCode = @DivisionCode, DivisionNumber = @DivisionNumber, TeamApproved = @TeamApproved, Paid = @Paid, Password = @Password WHERE TeamId = @TeamId"
runat="server" />
</form>
I apologize for the way the code is put in, the code thing cut off a lot of the text! The problem I'm getting is, when the 'Update' button is hit, I get the error: Must declare the variable '@TeamId'.
I've tried putting "Update Parameters", that takes away the error, but the row does not update. I've browsed the internet and saw the same problems in lots of areas, but either a) none of the solutions work for me, or b) they don't really apply to my case.
I'm using ASP .NET 2.0, and (obviously) C#. SQL Server database.
Any help is greatly appreciated. Thanks in advance,

I'm having trouble with my configurations. All of my configurations are targeting variables and the various properties are all set to expressions containing the targeted variables. I would like (during debugging) to dump out all of the variables.
Is there a way to access all variables from a script task? It looks like you have to enumerate the variables you want in the ReadOnlyVariables or ReadWriteVariables properties. I'd rather not miss one by forgetting to list it.

helo..
I have 100,000 rows in the database and I want to read results for eg: from 5000 to 5050 by DataReader.
I wrote this code to do this but its too slow:
Dim SlctStr As String = "select * from topicstbl where partID like '" & PagePartID & "'"
Dim ReadCom As New SqlClient.SqlCommand
ReadCom.CommandText = SlctStr
ReadCom.Connection = MainLib.MyConnection
Dim MyReader As SqlClient.SqlDataReader = ReadCom.ExecuteReader()
Dim StartTNum As Long = 5000
For IR As Long = 0 To StartTNum - 1
MyReader.Read()
Next
Do While MyReader.Read
StartTNum += 1
If StartTNum > 5500 Then Exit Do
'''''''''''''''''''
Loop
MyReader.Close()
is there another way to do the same thing better off than this code?

Hello all,
I have been struggling trying to read and/or write package level variables from within my custom task. I'd like to be able to get and set values from within the Execute method of my custom task. I have searched this forum and the books online and can't seem to find the answer. I thought maybe I could use an expression on my task (mapping the package variable to a custom task public property) but that doesn't seem to be working for me. I also would have thought I could use the VariableDispenser object from within my task but the collection is empty. I have 3 package level variables configured and can't seem to find a way to access them (with intentions of getting/setting). Could someone point me to a good doc or provide an example that may accomplish this? Thanks!
(I'm using package level variables as a means of passing simple information between tasks that are not using a DB, if there is a better way I'm open to suggestions.)

Hello, I am trying to configure a Script Component as a data source. Although this should be a simple exercise, I am running into a problem.
My control flow contains a Foreach Loop with a file iterator. The Directory Expression of the Foreach Loop Editor is supplied by an expression mapped to a package level variable called inputdirectory. The FileNameRetrieval Expression is mapped to a package scoped variable called filename.
My data flow is encapsulated by the Foreach Loop, and contains a Script Component as Source for the Data Flow Source, and a Flat File for the Data Flow Destination. The contents of the Script Designer are as follows:
Code Block
Imports System
Imports System.Data
Imports System.Math
Imports Microsoft.SqlServer.Dts.Pipeline.Wrapper
Imports Microsoft.SqlServer.Dts.Runtime.Wrapper
Imports System.IO
Public Class ScriptMain
Inherits UserComponent
Dim thisFileDate As Date
Dim thisFileName As String
Dim thisFilePath As String
Public Overrides Sub CreateNewOutputRows()
thisFileName = ReadOnlyVariables("filename").Value.ToString()
thisFilePath = ReadOnlyVariables("inputdirectory").Value.ToString()
thisFileDate = File.GetCreationTime(thisFilePath & "" & thisFileName)
FileSpecBuffer.AddRow()
FileSpecBuffer.FileName = thisFileName
FileSpecBuffer.FullPath = thisFilePath & "" & thisFileName
FileSpecBuffer.CreateDate = thisFileDate
End Sub
End Class
When I debug the package, I get the following error:
The collection of variables locked for read access is not available at this point.
at Microsoft.SqlServer.Dts.Pipeline.ScriptComponent.get_ReadOnlyVariables()
at ScriptComponent_67311120e6eb4162a3ea1f70847f04de.ScriptMain.CreateNewOutputRows()
at ScriptComponent_67311120e6eb4162a3ea1f70847f04de.UserComponent.PrimeOutput(Int32 Outputs, Int32[] OutputIDs, PipelineBuffer[] Buffers)
at Microsoft.SqlServer.Dts.Pipeline.ScriptComponentHost.PrimeOutput(Int32 outputs, Int32[] outputIDs, PipelineBuffer[] buffers)
My googlefu fails me at reconciling this. I have read various posts about changing the line ReadOnlyVariables("filename").Value to ReadWriteVariables("filename").Value, and handling the buffer assignment in PostExecute. The problem is that all examples shown are either for Script Component as Destination or Script Component as Transformation. I have tried playing with the Custom Properties in the Script Commponent set the ReadOnlyVariables and ReadWriteVariables, using a PreExecute method, a PostExecute method, all with different errors returning. I'm at a loss here. Could anybody provide me with a simple working example so that I can correctly populate my output buffer in the context of Script Component as Source?
I fully understand that I could just run a Script Task Using System.IO.Directory, and System.IO.File, but I really want to make this package work in the manner I've described. Any help would be appreciated.
Thanks,
John T

Hi all,
I am trying to build a association table (t2) to store a list of users
have viewed an item in my records table (t1). My goal is to send the
UserID parameter to the query and return to the user a read / not read
marker from the query so I can handle the read ones differently in my
.net code. The problem is that I cannot work out how to return anything
but the read data to the client. So far my stored proc looks like this
DECLARE @UserID AS Int -- FOR TESTING
SET @UserID = 219 -- FOR TESTING
SELECT t1.strTitle, t1.MemoID, Count(t2.UserID) AS ReadCount,t2.UserID
FROM t1
LEFT OUTER JOIN
t2 ON t1.MemoID = t2.MemoID
WHERE t2.UserID = @UserID
GROUP BY t1.MemoID, t1.strTitle,t2.UserID
It works fine but only returns those records from t1 that are read. I
need to return the records with null values also! I may have built the
assoc table wrong and would really appreciate some pointers on what I
am doing wrong. (assoc table has rID, MemoID and UserID columns)
Please help!
Many thanks

I have an excel file with following data:
Agent State Exposure Insured Name
Rogers Inc MA 100,000 John Smith
SAN Group RI 200,000 Jim Morrison
SAN Group RI 100,000 Jimi Hendrix
123 Agency MA 300,000 Mickey Mouse
Rogers Inc MA 50,000 Mike Greenwell
I want to be able to read the file and create new excel files for each Agent listed. So for Example, the above file would create 3 separate files since there are 3 different Agents listed. Each Agent file would contain the same information from the original file. The name of the file would be somethign like AgentName.xls...So the SAN group file would have this:
Agent State Exposure Insured Name
Rogers Inc MA 100,000 John Smith
SAN Group RI 200,000 Jim Morrison
SAN Group RI 100,000 Jimi Hendrix
Is there a way to accomplish this in SSIS?

The 2.0 version of ASPSTATE is slightly different than the 1.1 version in that one table has one additional column and another table uses a different data type and size for the key. The 2.0 version also has a couple additional stored procedures.
We'd like to manage just one session state database if possible so we're trying to figure out if Microsoft supports using the new schema for 1.1 session state access (it seems to work, but our testing has been very light).
Is there any official support line on this? If not, can anyone comment on whether or not you'd expect it to work and why?
Thanks.

I have a stored procedure that returns a resultset AND an output parameter, pseudocode:myspGetPoll@pollID int,@totalvoters int outputselect questionID,question from [myPoll] where pollID=@pollID @totalvoters=(select count(usercode) from [myPoll] where pollID=@pollID)1. In my code behind I'd like to read both the rows (questionID and question) as well as total results (totalvoters) How could I do so?2. what would be the signature of my function so that I can retreive BOTH a resultset AND a single value?e.g.: private function getPollResults(byval pollID as integer, byref totalvoters as integer) as datasetwhile reader.read dataset.addrow <read from result>end whiletotalvoters=<read from result>end functionThanks!

I have the following query:
Select p.Id [SenderId], p.Username, up.PhotoId,
CASE
WHEN mr.ReadDate is null then 1 -- New message
ELSE 0 -- Message has been read
END AS NewMessage,
p.LastLoggedIn, p.LoggedIn
[Code] ....
The above query returns me all messages (inbox functionality) that have been sent to mr.ReceipientId, the issue I have is when I send another email to the recipient the readdate field will be null, and the other emails linked to the recipient which have also been sent via me will have a readdate date. This causes duplicate rows to appear due to the case statement, I'm trying to figure out if / how it is possible to only display the one row per conversation and set newmessage to 1 if there is an un-read message otherwise show 0 ?
So instead of showing this:
2Person102015-07-26 17:07:24.9370
2Person112015-07-26 17:07:24.9370
I'm trying to get it to look like this:
2Person112015-07-26 17:07:24.9370
Or if we have no new mail (read date is not null) then it will appear like this, and I can confirm when there is no new mail it works as expected.
2Person102015-07-26 17:07:24.9370

Hi,
I am not comfortable with DTS 2000 but I need to execute a encapsulated DTS 2000 package from a SSIS package. The real problem is when I need to pass SSIS variables to DTS 2000 package. The DTS 2000 package have 3 global variables that I can identify on " Execute DTS 2000 Package Task Editor - Inner Variables ". I believe the SSIS variables must be mapped on " Execute DTS 2000 Package Task Editor - OuterVariables ". How can I associate the SSIS variables(OuterVariables ) to "Inner Variables"? How can I do it? Much Thanks.

Hi,
I would like to design a SSIS package, which have couple of variables. It loads a xls file specified in a variable [varExcelFileFullPath] .
I will run it by commands: exec xp_cmdshell 'dtexec /SQL ....' (pls see an example below).
It seems it does not get the values passed in for those variables. I deployed the package to a sql server.
are there any grammar errors here? I copied it from dtexecui. It worked inside Dtexecui not in dos command.
exec xp_cmdshell 'dtexec /SQL "LoadExcelDB" /SERVER test /USER *** /PASSWORD ****
/MAXCONCURRENT " -1 " /CHECKPOINTING OFF /REPORTING EW
/LOGGER "{6AA833A1-E4B2-4431-831B-DE695049DC61}";"Test.SuperBowl"
/Set Package.Variables[User::varExcelFileName].Properties[Value];"TestAdHocLayer"
/Set Package.Variables[User::varExcelWorkbookName].Value;"Sheet1$"
/Set Package.Variables[User::varExcelFileFullPath].Value;"D: estshareTestAdHocLayer.xls"
/Set Package.Variables[User::varDestinationTableName].Value;"FeaturesTmp"
/Set Package.Variables[User::varPreSQLAction].Value;"delete from FeaturesTmp"

i have a database which get refreshed every day from client's data . and we need to pull heavy data from them every day as reports . so only selects happens on that database.
we do daily population of some table in some other databases from this daily refreshed DB.
will read uncommitted or NOLOCK with select queries to retrieve data faster.
there will be no dirty read as there are NO DML operation in that database so for SELECT which happens concurrently on these tables , will NOLOCK work?

I have the table populated and it is not coming back with "login successful" or "password wrong" when I've entered correct information. Enclosed is what I've done in VS2003. Can you see where my error is? Any help would be greatly appreciated.
