I'm new on ASP.NET 2.0
Can anyone tell me how to get data from SQL to Session properties?
In Classic ASP, it looks very simple as below.
dim conn
set conn = server.createobject("adodb.recordset")
rssql = "select myid, mypw from mydb where myid = '"& request("myid") &"' and mypw = '"& request("mypw") &"'"
set rs = conn.execute(rssql)
if rs.eof = true then
session("myid") = rs("myid")
session("mypw") = rs("mypw")
end if
How to do the same things on ASP.NET?
Many thanks!
Hiya!I've combed the SQL Server 2000 online help but I don't see anythingakin to Sybase ASE's 'montor' views - equivalent to Oracle's V$views. The views are performance views which contain per sessioninformation such as:- SPID- number of logical read/write and physical read I/Os accumulatedthus far- CPU accumulated- Memoryetc.Does anyone know if I can snarf that data from SQL Server 2000?Thx!--Pablo Sanchez, Blueoak Database Engineeringhttp://www.blueoakdb.com
I'm trying to write data from a session into database but it won't work. Could someone help me what is wrong with this.
cobjDT = Session("cart") For each cobjDR in cobjDT.rows Dim cmdInsert2 as New SQLCommand("order_details", loConn) cmdInsert2.CommandType = CommandType.StoredProcedure
cmdInsert2.Parameters("@Mangd").Value = Request(cobjDR("Quantity")) loConn.Open() cmdInsert2.ExecuteNonQuery() loConn.Close() next
When I execute this an error message comes
Server Error in '/examen' Application.
Input string was not in a correct format.

I use same character types in storedProcedure what they are in the database and when I call the SP on my page the char types are same as they are in the SP
I'm having trouble using session data in my select parameters. If I manually plug a value into the selectcommand or create a hard coded value using a parameter it works, but if I try to use the session data the query pulls no results. I know the session data is set because I print the value at the top of the page, but for some reason it's not getting passed to the sessionparameter??? This is the datasource code: <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:flautoconnstr %>" SelectCommand="SELECT * FROM [tblVehicles] WHERE ([profileid] = @profileid)"> <SelectParameters> <asp:SessionParameter Name="profileid" SessionField="profileid" Type="String" /> </SelectParameters> </asp:SqlDataSource>
This is the line I use to set the session data. Session["profileid"] = myQuote.Profileid;
I like to know how I may store some user-specific data at the beginning of a session and retrieve the same data later during the session in a SQL command. For those of you familiar with ORACLE, I am trying to mimic the SET_CLIENT_INFO and GET_CLIENT_INFO functions of ORACLE's DBMS_APPLICATION_INFO package on SQL Server.
I downloaded a copy of sql server and when I run the following query in the sql management studio after choosing new query , DMX I get the above error
CREATE MINING MODEL [NBSample]
(
CustomerKey LONG KEY,
Gender TEXT DISCRETE,
[Number Cars Owned] LONG DISCRETE,
[Bike Buyer] LONG DISCRETE PREDICT
)
Using Microsoft_Naive_Bayes
Also in the pane Mining Model I get the message No mining models found. The only error I get when I installed SQL server was a COM plus registration error. I am running Windows XP SP2. Can someone please help.
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?
I have created a session in extended events and want to frequently monitor the events that i have filtered .The problem i am facing is i am not able to clear the previous data as we do it in SQL trace. i am able to see all the data that is occupied till now.whenever i start the test i want the current data only to be displayed.The work around is either delete the session and create a new one every-time which i do not want to do .I am able to see the CLEAR DATA FROM TABLE button but it is in Disabled state all the time.
I need some solution.. When i execute a program it first deletes all datas from a 'X' table .Then fetches data from various other tables and inserts into this 'X' table.I finally generate a report from this 'X' table.
Now the problem is, USER 1 : Executes the program - Datas in 'X' table got deleted and filled up with new data.Report is getting processed..... USER 2 : Executes the same program - Datas in the same 'X' table getting deleted .. So the report process of USER 1 got affected.
Solution 1 : Using IP address of local machine i solved the problem.But i need a concrete solution for this ..something related to sessions..
How do you return the ID of an item to a Session in a ASP forum? I have a MS-SQL Server 2005 database. My table looks like this QuoteID, QuoteNumber, Date. In SQL: INSERT INTO table (QuoteNumber, Date) values ('123490WC1", '06/2/2008')DECLARE @ItemID INTSET @ItemID=IDENT_CURRENT('table') What I would like to do is return @ItemID to the ASP forum; I assume Session would be the best. After I get the @ItemID I have a Grid which I will to insert the Quote Items into. Thanks, marly
Hi, Can somebody tell me what's wrong with this statement or why the Session parameter is not working. <asp:SqlDataSource ID="datalist_SQL" runat="server" ConnectionString="<%$ ConnectionStrings:DatabaseConnectionString2 %>" SelectCommand="SELECT * FROM tbl_subProduct, tbl_material, tbl_product, tbl_subCategory, tbl_topCategory, tbl_topLevelProduct WHERE [tbl_subProduct].[numProductID] = [tbl_product].[numProductID] AND [tbl_product].[numTopLevelProductID] = [tbl_topLevelProduct].[numTopLevelProductID] AND [tbl_topLevelProduct].[numSubCategoryID] = [tbl_subCategory].[numSubCategoryID] AND [tbl_subCategory].[numTopCategoryID] = [tbl_topCategory].[numTopCategoryID] AND [tbl_material].[numMaterialID] = [tbl_product].[numMaterialID] AND @fldArray "> <SelectParameters> <asp:SessionParameter Name="fldArray" SessionField="ids_array" Type="Int32" /> </SelectParameters> </asp:SqlDataSource> Many Thanks
Hi... I'm developing a web app with VS 2005 Beta and I do not know how to include a seasson variable value into my code.
This is my code:
Function GetData() As System.Data.SqlClient.SqlDataReader Dim sqlconn As System.Data.SqlClient.SqlConnection Dim SqlCommand1 As System.Data.SqlClient.SqlCommand Dim sqlRdr As System.Data.SqlClient.SqlDataReader sqlconn = New SqlConnection("SERVER=SRVR;UID=USR;Password=PWD;DATABASE=MyDatabase") sqlconn.Open() SqlCommand1 = New SqlCommand("MyStrProc", sqlconn) SqlCommand1.CommandTimeout = 1800 sqlRdr = SqlCommand1.ExecuteReader(CommandBehavior.CloseConnection) Return sqlRdr End Function
MyStrProc is:
CREATE PROCEDURE MyStrProc @MyVar int AS IF @MyVar IS NOT NULL BEGIN ................. ......t12.acct_nbr IN (@MyVar) ..... END GO
The variable @MyVar get its value from user log info in login page, and create a session variable.
My Question:
How and where to call seasson variable @MyVar, because now I'm getting this error: Procedure 'MyStrProc' expects parameter '@MyVar', which was not supplied.
I want to open a new session/connection inside the execution of a stored procedure. Is this possible ? I ask this because I need a new sesssion with its own transaction.
Can we use session variable in reporting services.. say go to report -> properties and create a VB function that get ans set session variable.. If yes, how. If not, any workaround?
I have designed reports using SQL Server Business Intelligence Development Studio tool (Sql Server reporting service). I have uploaded these reports to report manager.
I am displaying list of reports in tree view control, in my application. I am viewing report in Report Viewer control as per the report selection in tree view control, in same page. I am getting
Server Error in '/Application_name' Application or ASP.NET session has expired error frequently while switching between various reports. Kindly provide me solution
Ok, I am trying to teach myself asp.net and sql server. The problem I am having now is I want to update the session that already exists. I have a global session (I think) that is UserEmployeeID, it is inputed when a user selects the select link on the search page which will redirect to an info page. I want to change the employee to a different employee, well I am updating the database well, no that is a lie it doesn’t that is another error, but anyway I try to update it to the new EmployeeID and it will not update…

Hi, I try to set a Session variable with the result of a SQL Selec statement. I tried the following, but it is not working. Session("thisone") = SqlDataSource1.SelectCommand = "SELECT myfield FROM [mytable] WHERE ([username] = @username)" @username is a value from a textbox. What I am doing wrong? Thanks for your help, Chris
I have some C# code that iterates through the session state, serializes each object and stores the binary representation in an SQL table with an 'image' column. The problem is: it doesn't work. SQL server doesn't throw an error (at least ADO.NET doesnt propagate it); the table is just left unchanged. The SP works (I tested it with a few simple values); the MemoryStream and byte array are being populated correctly and bound to the parameter correctly.
What am I doing wrong? Anyone have a better approach? I know there is a builtin way of storing state in an SQL server, but I only need to do this once--namely, when a user is redirected from non-secure to secure pages--so I don't want to take that performance hit,
Does SQL Server have a session browser similar to Oracle and if so, how can I use it? I am looking to retrieve the SQL being ran when users are running particular reports from a gui tool.

Hi,does someone know how much memory a user session takes on a SQLServerdatabase server? How many concurrent user sessions can a normal server(4 GB primary memory) handle, before connection pooling is needed?/Fredrik
I`m using IIS7..At present, our company has come not a difference indeyo of operating the server using Classic ASP recently we met a big problem : session is increases indefinitely. 503.3 - ASP.net has a queue is full. The phrase occurs continuously. Is there any solution for check problems? or how can i see what source code page makes the problem (ex. 123.asp : session 300. 234.asp : session 4000).
I have a master package that executes a series of sub packages. The master package is run from a SQL Agent job. The packages are reading from and writing to two databases on the same instance of SQL Server 2005.
If I set the Execute Package Tasks for the sub packages without any precedence constraints between them and set TransactionOption = Required at the master package level (and supported from there downwards) I get the following errors.
The event log shows me:
The SSIS Runtime has failed to enlist the OLE DB connection in a distributed transaction with error 0x8004D00A "Unable to enlist in the transaction.".
Running a SQL Profiler trace shows me:
Error: 3910, Severity: 16, State: 2 Transaction context in use by another session.
This problem is well documented and seems to go back to DTS in SQL Server 7.0 . . . see http://support.microsoft.com/?scid=kb;en-us;279857&spid=2852&sid=150
I can get round it by setting precedence between the sub packages - making them run one at a time solves the problem. But then we don't get the performance benefits of running the packages concurrently. Does anyone have any other solutions.
This procedure has a begin trans and a commit. In this procedure i'm inserting data into tables. This data is provided by an extrenal app in staging tables. On the tables i'm inserting data on i'm having triggers that again are starting a SP2. I'm using a cursor on the inserted table to achieve this. The SP2 only insert a record on a table that is on a linked server.
For testing reasons at this moment this is my dev machine too.
