DataSource Controls :: Invalid Column Name 'ContractDocumentType'
Jun 3, 2010
I have two drop down lists and a upload control. One dropdown allows my user to select a valid contract number, and the second dropdown is populated from a table that has 5 contract document types and id's.
after i use the dropdowns to select the information i want and select the file i want to upload based on that information, I press my upload button and get " Invalid column name 'ContractDocumentType'."
It is very possible that I have extra code in here that is not necessary as I have fixed several issues before this one, such as a convert varchar to int error.
What Contract Number Are These Documents Related To?
When I run this the error is 'Invalid column name 'assigned'.'Yet if I load up Microsoft sql server management studio and run the query against the same db:
[Code]....
I get the data I was expecting and the column does exist?
I have a SQL Server 2005 database which is queried by a web service which is called by an aspx page.
I inherited a messy and inefficient project, and I was working on cleaning up a GridView by making it dynamic and by having consistent field names in the database when I started getting an error of - Sys.WebForms.PageRequestManagerServerErrorException: Invalid column name: 'ASSIGNED_TO'
Assigned_to does not exist in the database, in the web service, or in the website solutions in any place. It was the name of one of the fields in one table, which I changed to USERID so that either of two datasets would fit into a Gridview (all other fields were the same). I then replaced all references of ASSIGNED_TO with USERID, which is when the issues began. The first of the two queries below causes the exception to be thrown, but the second one does not. I have tested both with the WCF Client and with a query within SQL Server to verify that they do work, so the issue has to be on the website side.
sSQL = "select distinct B.BADGE_NBR, a.REGId,B.CYC_RTE, b.USERID, a.MTRREAD,A.NEWMTRNUM, a.COMPTIME, B.FA_TYPE, CASE WHEN A.MTRCOMMENTS <> 'Null' THEN '*' END as Comment,a.MTRLAT,a.MTRLONG,a.WOFAID, b.ADDRESS, a.MTRREADFLAG, b.ROUT_SEQ from MobileDataReturn a,WORKORDERDIPATCHFILL b Where a.RegId = b.REGID and a.WOFAID = b.FA_ID and B.CYC_RTE " & route & "' and b.USERID " & worker & "' and B.BADGE_NBR " & badge & "' and a.MTRREADFLAG " & readflag & "' and b.FA_TYPE " & fatype & "' Order by a.COMPTIME desc"

I am making a project on vb .net. I am using the connection string , "Data Source=.SQLEXPRESS;AttachDbFilename=""|DataDirectoy|Database.mdf"";Integrated Security=True;User Instance=True". My login page was running untill yesterday but now its giving the error "Invalid value for key AttachDbFilename"
I'm currectly tryin to access a specific value in my database in a specific column. I'm tryin to use the primary key of the table to access the actual value in the row of that ID.
The current code:
[Code]....
Just iterates through the table and looking for any row with the boolean 'checkin' value is True, then it takes the 'id' value of that row and stores it into an array. Is there a way that I can access a another entry, and only that entry, in the table with the 'id' stored in the array?
Like if my data base contained and int, primarykey, `id` value, a boolean, `checkedin` value, and a `time` value, is there a way to access, lets say, the row with `id` equalling 3 and and the checkIn value from that row?
USE [fedach] GO /****** Object: UserDefinedFunction [dbo].[pages_Allowed] Script Date: 05/18/2010 14:14:34 ******/ SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO CREATE FUNCTION [dbo].[pages_Allowed] (@username varchar(35)) RETURNS varchar(30) AS BEGIN -- Declare the return variable here DECLARE @pages varchar(30) DECLARE @PRvalidate tinyint,@PRdownload tinyint,@PRupload tinyint, @Pages as varchar(35) select @PRvalidate=Rvalidate,@PRdownload=Rdownload,@PRupload=Rupload from tblPermittedpages where Username=@username; select @Pages = case when @PRvalidate=1 and @PRdownload=1 and @PRupload=1 then 'Admin' when @PRvalidate=1 and @PRdownload=0 and @PRupload=0 then 'Validate Only' when @PRvalidate=0 and @PRdownload=1 and @PRupload=0 then 'Download Only' when @PRvalidate=1 and @PRdownload=0 and @PRupload=0 then 'Validate and Download' End; return @pages END
But when i am running the function i am getting the error as Invalid object name 'dbo.pages_Allowed'. can any one tell why?
If I use local SQL database, everything working fine, but when I change database link to Web SQL server this error pop out, and I have no idea. Anyone know what happen? My error as below:
Server Error in '/' Application.
Invalid object name '訂單'.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code
Exception Details: System.Data.SqlClient.SqlException: Invalid object name '訂單'.
I have several methods where I return a SqlDataReader to populate Gridviews, Listview, etc. I get random "Timeout expired" errors regarding connection pooling, so I decided to add using{} to my methods. The lack of using is a carry over from my more beginner days.Below I included the before and after code. The after code always gives me the "Invalid attempt to call FieldCount when reader is closed" error. I have tried various combination of using{}, but ALL result in the same error.What am I doing wrong? Also, from the code below what is the best way to structure this code to ensure no connection leakage?Before:
Environment is : vwd2008, asp.net 3.5, linq to sql object model, formview, stored procedure used for query.On going problem... I have a simplified page with a webform content area from a master page. The content area contains a FormView connected to an object data source thru the design view tag. The O/R designer has the Lease Table and the stored procedure in the method area.
The stored procedure selects all records from a single table. I an using the DatabaseDataContext and selecting stored procedure name which has "return SingleResult".. There is no code written; the design view was used to create everything. The stored procedure executes in VWD 2008 express tab and shows desired records. I would like to use the O/R and Linq to SQL, and objectdatasource BUT.
Scenario: I am creating a custom gridview control which has a custom CheckBoxTemplateField column (deriving from TemplateField class). This template field column has custom Checkboxheadertemplate (implementing ITemplate) and CheckboxItemTemplate (also implementing ITemplate). In InstantiateIn method of both templates (header as well as Item template), I am adding a checkbox control which has Autopostback = true.
My requirement is: I want to mark all the values in the binding column of datasource if checkbox in headertemplate is checked. I dont want to mark only rows visible on grid. I WANT TO MARK ALL ROWS IN DATASOURCE. I want to do this in _CheckedChanged event of checkbox in header template.
Problem I am facing: When I check/uncheck the checkbox in header, it postbacks. so in OnCheckedChanged event, gridview's datasource is null. Secondly, in any event of gridview, I could access only those rows of datasource for which corresponding rows are visible in gridview through Gridviewrow.DataItem property. But I want to set it for all rows in datasource.
when I insert any character to column Name then A new string random will auto insert into column Random (picture below) I had used Trigger but It was error !
I want to column Random use to code :
DECLARE @myid uniqueidentifier SET @myid = NEWID() insert into table_1 values(@myid, substring(CONVERT(varchar(255), @myid), 1, 5))
but It must auto like column Number (column Number is Identity)
