SQL Server :: Tracking Down Data Conversion In Sql Update?
Dec 27, 2010
have been working this issue for the last two days and I cannot for life of me track down the problem. I am using an Update parameter statement to update records in a sql db. I have done all the debugging in VWD but I get no specific error line details. I think it is a mismatch type with the primary key field. Below is the stacktrace:
[SqlException (0x80131904): Error converting data type varchar to numeric.]

Page1 contains GridView1 which displays info from Table1.GridView1 contains a CommandButton which, when clicked inserts the values of all columns, plus a calculated value which goes into an extra column into Table2 handled in the RowCommand event handler of GridView1.Page2 contains GridView2 which displays info from Table2.GridView2 allows the user to alter the value of one of the columns in Table2 using the standard Edit/Update link.All this worked well until...I added UserId and SessionId fields to Table2 (uniqueidentifier and varchar(MAX) respectively,I added the following code to Page1 Code Behind to insert these values from the RowCommand handler:
[Code]....
All of this works beautifully. But... I then added this code to GridView2's RowUpdating event handler:
I'm a bit cautions about converting one of my sites to .net 4 at the same instant I move to vs2010. When I convert the sln and csproj files, there is an option to "convert web sites to .net 4" which I did not check.Once I get more comfortable using vs2010, I'd like to do that conversion to .net 4, but I can't find an option to do that in VS.

We have a web part on which we display some data in a grid. We are exporting grid's underlying datatable to Excel and displaying Open - Save - Cancel dialouge box on click of a server side button.Following is the code we are executing on click of server side button.
this.Page.Response.Clear(); this.Page.Response.AppendHeader("Content-Disposition", "attachment; filename=MyTasks.xls"); this.Page.Response.ContentType = "application/ms-excel"; this.Page.Response.Write("...here goes my well formated html...."); this.Page.Response.End();
Problem is that when i click on Cancel in the diaglouge box then dialogue box to Open/Save excel disappears but all the server side buttons placed on my web part becomes non responsive, on click of any of those buttons their server side click event does not get fired
I've got a simple detailsview on a webpage for viewing, adding, and updating inspectors. Since it is a simple details view I'm just used the datasource select, update, delete, and insert commands. When I debug the page it populates the detailsview appropriately and allows me to page through the inspectors but when I try to update a field I'm getting the implicit conversion error in the attached doc. Below is my detail view markup. I was thinking the error is caused by the checkbox type being boolean while the SQL type for "Active" is bit but I've tried to use various conversion methods and can't seem to get them to work.

I have developed a Portal (Request submission) which sends an Email and also it updates all values to the Database. What ever values gets updated to the database, will be sent as an email message to an address. It works fine. I need a Unique number to be generated for a Request submission which has to be sent in the Email message and also it has to be updated in the database. I use SQL Server 2005 and Framework 2, C# laungauge.
I have been messing about with this for hours surely this should be an easy task ....... I have a stored procedured that creates a invoice on a Quotetable one of the parameters is a output parameter Invoice Number this is passed to a label. (Label1) This works great.
I then need to add items to the invoice on a item table so my next stored procedure should take the value of Label1 and update the foreign key quotenumber on the itemtable with the value from label1.
On the aspx page I have a small section for a gridview which shows the current quote with however many items on it using the control
[Code]....
On the ASP page the control for @Quotenumber = Label1 but I get the following error
'Conversion failed when converting the nvarchar value 'Label' to data type int.'
I just realize this difference in date conversion: In SQL server, if you run the code below
declare @dateStr varchar(20) set @dateStr = '1/1/49' select cast(@dateStr as smalldatetime) you will get "2049-01-01 00:00:00" In .NET taking string with value "1/1/49" and it will turn into 1/1/1949 12:00:00 AM DateTime dateObj; dateObj = DateTime.Parse("1/1/49"); Label1.Text = dateObj.ToString();
Can anybody tell me why Microsoft did this and what is the best way to prevent user from entering 2 digits year?
I need to export the data from .dbf file to sql server2000. if any body can guide me how to do that. I'll be really grateful. DBF file has lakhs of records which need to be transffered.
I need to log every user-action taken on a database using the username of the person logged into my ASP.net application as the identifier in the log. What is the easiest way to do this? I guess that for every method call to my data access layer I need to log the parameters of that call and the username and then call a new "log event" method that writes the details of the call to a table. Am I on the right track?
how I can get around the following error with the following code?
[Code]....
Error: Msg 8169, Level 16, State 2, Line 1 Conversion failed when converting from a character string to uniqueidentifier. As you can probably tell, the datatypes are: m.UserId = uniqueidentifier l.System_User_ID = varchar(256) I was hoping the casting of one to the other would solve the issue, but it doesn't. How can I re-code this? I see from other forums it would probably be best to set all these fields to uniqueidentifier, but would prefer not to at this stage as it will involve changing quite a bit throughout the whole site!
Sorry, not sure if this is the right place for this. I have a requirement to convert Word, Excel and HTML docs to PDF format programmatically, but most information online seems to be talking about client side. What is the best approach for this. I think there would be about 100 conversions a day in production. It's not high volume.
I am trying to match a username to a userid which are in 2 different sql tables. Here is my select statement:
SELECT aspnet_Users.UserName FROM aspnet_Users INNER JOIN aspnet_starterkits_Projects ON aspnet_Users.UserName = aspnet_starterkits_Projects.ProjectManagerId
When I run this i get an error message: "Conversion failed when converting from a character string to uniqueidentifier" Is there anyway around this? Or a different select statement etc?
once executing, I am getting following error: Conversion failed when converting the varchar value 'insert into Employee(EMPID,EMPNAME,EMPLname) select ' to data type int.
