SQL Server :: Using Session Variable Value In An Insert SQL Statement?
Jan 7, 2011
This should be really simple and I am new to asp development.
I am using ASP log in controls..when user logs in, I am storing the userid in a session variable. On this another page, I want to put the previously stored session variable value into a table using Insert statement.
in my sqldatasource..here is the code..
InsertCommand="INSERT INTO tblMain(PatientId, UserId, IncAge, IncDeNovo, IncAnginaIschemia, IncNative, IncLesions, IncStudyConform, IncStenosis) VALUES (@PatientId, @UserId, @IncAge, @IncDeNovo, @IncAnginaIschemia, @IncNative, @IncLesions, @IncStudyConform,
@IncStenosis)">

I am new to all this, and ignorant beyond compare. I believe I have the same problem as this :
[URL]. However, the solution proposed for him doesn't seem to work for me. I have a session variable that 'march_cpi_session' that I wish to include in an sql select statement to multiply the values I get from a datatable before they're used to populate a gridview control. The session variable works fine elsewhere in my application, but causes a variety (depending upon how I fiddle about with the syntax) of sql errors. This is the currrent code:

if (Session["image"] != null)
{
ImageButton1.ImageUrl = "~/IMAGE/pic.jpg?" + DateTime.Now.Ticks.ToString();
}
The session key image is from another aspx page
{
string strPhoto = Request.Form["imageData"]; //Get the image from flash file
byte[] photo = Convert.FromBase64String(strPhoto);
FileStream fs = new FileStream(Server.MapPath("~/IMAGE/pic.jpg"), FileMode.OpenOrCreate,
[Code]....
The issue is
Operand type clash: nvarchar is incompatible with image.

I have this select statement which joins two tables and produces one column as its result. What I'm figuring out is how to add this data into another table as a new column. The output of the select statement and the table I'm going to transfer the data to has the same number of rows. Should I put it first in a temporary table? This column shouldn't allow nulls also.

I have a select statement and want to be able to insert some spaces in the returned data:
[Code]....
For the parts with ' - ', I want to remove the dash and simply put spaces now. But when I remove the dash and put 4 spaces, I only get one space. How do I put in those 4 spaces?

We recently migrated a web app from one Prod server (Prod 1) to another server (Prod 2). There is a session varialbe checked inside the page load event of the default master page. I have enabled session state both in web.config as well inside the pagedirective. The compilation went through without any issue. The web app is also running just fine on the server but the log file keeps logging a warning message. There is no run time error.
"System.Web.HttpException: Session state can only be used when enableSessionState is set to true, either in a configuration file or in the Page directive. Please also make sure that System.Web.SessionStateModule or a custom session state module is included in the <configuration><system.web><httpModules> section in the application configuration."Any idea why this is happening on one server vs other?

Currently in an .aspx file, I am storing a value (filename that was created in that session) in an hidden text box. When the user clicks on the "Print" labeled Hyperlink control, it opens the file that was stored in the hidden text box control. But when the user goes to different screen (in the same session), I loose the filename value that is stored in the hidden text box control. So I would like to store the filename variable in a session variable. So that if the user leaves this .aspx file and comes back to this .aspx file I can load the value into the hidden text box from the session variable.

I want to use session variable for ConnectionStrings in SqlDataSource, so the same script can be used with different users with different databases. My SqlDatasource code is :
<asp:SqlDataSource
runat="server"
ID="sdsAvdeling"
SelectCommand="SELECT
* FROM [Avdeling] ORDER BY [Avdeling]"
ConnectionString="<%$
ConnectionStrings:UtstyrConnectionString %>">
</asp:SqlDataSource>
In Page_load, I assign the connectionstring for the SqlDataSource like:
sdsAvdeling.ConnectionString = Session["ConString"].ToString();
where
Session["ConString"]
is assign to "UtstyrConnectionString" when the the user logs in. When running the script, I get the following error: System.ArgumentException: Format of the initialization string does not conform to specification starting at index 0.

OK, this may be a little difficult to explain, so I will try my best and post the code I currently have.
I have a table with a list of usernames. I have the list of usernames displayed on a page through a GridView. What I am attempting to do is for each username in the column "adminUsernames", I need to insert a set of values in another database table for EACH "adminUsernames" that exists. Example: There are 2 adminUsernames vales in 2 seperate rows. These are "Admin 1" and "Admin 2". For each adminUsername values (Admin 1, Admin 2), I need a row interted in another database table. Maybe the code that I have (that does not work) will help you see what is happening:

I keep receiving this error when running: [Code]....

I had a .net 4.0 vb.net page that was setting session variable and setting a hidden form value to the same value. It was a paypal buy now button. When the user selects it, they are sent to paypal for payment. If the transaction is good, they are redirected back to another page on my site and a hidden value is sent back with the invoice I originally sent them. They are sending the form value, but my session variable does not available.
From the user point of view it's all seamless.. Is it the same session? And should my session variable be available?

In my asp.net website I am creating a session upon user login and I would like to perform some operations in the database just before this session will expire.I am having problem in determining where should I write code and how will I know the session is going to expire.
I am not sure if 'session_end' event of 'Global.asax' suits my requirements as the session I want to check is created manually(not a browser instance).

I have a project that I was using Access for but now find I have to change to SQL Express. Well I have no big problem with that but I now find that the SQL Statement I have been using was for OLE and does not work in SQL/Express. I am not even sure anymore if I can dump the entire CSV file in at one time? The statement I was using is below.
[Code]....
Here is my problem. What is the INSERT statement to insert a complete flat (CSV) into SQL Express? OR what method can I use to preform this task?

I have a web application which uses a session variable to store the logged in userid. If no user is logged in, of course this variable will be empty and the contents displayed on my website are meant for guests. If there is a user logged in, the user specific controls/access/links will then be a displayed.
I am now having issues with my hosting where on shared application pool, the worker recycle is triggered every 90 minutes, this will clear sessions causing all my users to be logged out. I opted for a dedicated application pool, which got worse because I am only allocated 50MB memory limit and if this is reached, the worker recycle is triggered and I lose my sessions again. I have tried as much as possible optimization techniques, e.g. dispose where possible, close connections, disable viewstate for static controls etc but my memory per instance keeps building up from page to page without any signs of improvement. I don't use loops nor store huge objects like bitmaps etc but my sessions are now gone even faster than 90 minutes in shared application pool before.
I have considered using SQL Session State but there isn't a simple guide on using this with MySQL. I am getting desperate and considering using a public variable, a string as a replacement to store logged in user id instead of in a session variable. I am pretty sure this will solve my issue with sessions being recycled but are there any negative consequences of doing this? One problem I can think of is if the user closes the browser, the system will never know that the user is now logged out and this public variable should be nothing. In this scenario, will the GC eventually clear this abandoned public variable.

What would be the proper syntax in ASP.NEt 3.5 C# to assign a TextBox value to a temporary or session variable to be manipulated (added, subtracted, multiplied, divided) at different points in the application? I want to add a decimal number to this variable in almost every instance as well.

I have the dataset. in this i am having total 20 tables with huge amount of data..I want use this data over all the page..so where i can keep this data..
before i used viewstate but the viewstate data is render to page every postback ..so this time the page size is increasing(interanlly viewstate is rendered to page)..so performence wise it was very slow..
Now i change my logic insted of viewstate to i used Globel Dataset on Page Level.. now the performence wise better than viewstate..
i used Like shared dsControls as Dataset at top of the page..so every time i use this dataset..
my quesation is session is better or Globel variable is better way use in my situavation..
