DataSource Controls :: Getting Error While Inserting The Values To Parameters?
Mar 19, 2010
I'm using Enterprise library, but the idea is the same. I have a SqlStringCommand and the sql is constructed using StringBuilder in the forms of "insert into table (column1, column2, column3) values (@param1-X, @param2-X, @parm3-X)" + " ";where "X" reprents a "for loop" about 700 rows like so
[Code]....
So after all is done, I have 700 insert statements in one batch and of course, I did another 700 loops and added the values to those parameters. It runs fine and fast for a few days. However, last night, suddenly I get this error
Using the properties as defined in a class, how about can I put them into the ParamArray parameters argument of my function. The code as follows:
Public Class MyObject Public Property Prop1 as string Public Property Prop2 as integer Public Property Prop3 as Boolean Public Sub AddNewMyObject MsSQL_ExecuteNonQuery("StoredProc_AddNewMyObject", ________________?) End Sub End Class Protected Function MsSQL_ExecuteNonQuery(ByVal storedProc as string, ByVal ParamArray parameters as object()) 'Some Code here. End Function
I have 3 dropdownlist with day,month(e.g Jan, Feb...) and year value. However I am getting an error from my code when trying to insert the concantenated values into a date field in sql server 2008.
This table receives data from my web application via a stored procedure, snippet pasted below:

In my quote.aspx page, I have a wizard control that collects numerous data points. In one of the wizard steps, I have 20 textbox controls for PartNumbers and 20 textbox controls for respective Quantity.
Question:How do I write a for..each loop that checks for values in my Part Number and Quantity fields and inserts them via my SQLDataSource?
I have the logged-in user's Guid stored in a session variable. My understanding is that when the Guid is passed to the session variable it becomes a string. When I use the detailsview control I have to convert the session variable back to a guid and I've been doing it like this and it seems to work fine:
e.values("UserId") = session("LoggedInUserId") Dim UserId as Guid = New Guid()
When I try to use the Insert() command after the following:
I get an "InvalidCastException" error with the comment "Conversion from type 'Guid' to type 'String' is not valid." I'm assuming the session variable needs to be converted to a type Guid since that's what I've had to do with the Detailsview control. I've tried a few different ways of converting the session variable back to a Guid so the insert command will work, but no matter which method of conversion I try I get errors such as "value of type system.guid cannot be converted to 'string'. I'm confused because I thought I was supposed to convert it from a string to a Guid. The "UserId" parameter is a non-primary key uniqueidentifier in the database.
I have a SQL datasource, hooked to a gridview. When i submit my updated row, the update parameters fills with the original values, instead of the new values. Am i doing something wrong? I have tried to handle everything in the html, and not code any parameter settings. All my update parameters are called the same as the field in my gridview, and i use a prefix infront of the parameter names in my updatecommand, in my case : (instead of @) since i use oracle.
I am not able to figure out why I am getting the null error at SqlDataSource10.Insert(); I tried running through break points and i checked the Insert statement and it has all the required values .. but I get error saying it cannot insert null into NrNarrativeDays. I am working off a sample at this link..
I am attempting inserting into an Access database, and the insert is successful (when I open the database the data is there), but I'm getting an error: "The changes you requested to the table were not successful because they would create duplicate values in the index, primary key, or relationship. Change the data in the field or fields that contain duplicate data, remove the index, or redefine the index to permit duplicate entries and try again."This is really confusing me. No matter what I insert, it still gives me the same error. And I don't understand why it's giving me an error even though it's working. Here's my codebehind:
Protected Sub Wizard1_FinishButtonClick(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.WizardNavigationEventArgs) Handles Wizard1.FinishButtonClick 'Collect Data
I am very new to ASP .NET and am getting above error when trying to insert a new record into a SQL database. I have turned on Option Explicit On so the default date of 01/01/1900 does not get assigned to this field automatically. Since most of the people in the database will not have a date of death, I need to have "blank" deathDate. When I run the stored procedure within SQL and choose pass null value, the Insert Procedure works fine. When I attach to Web Form, however, I get String was not recognized as a valid DateTime error. How can I set it so Null values are accepted into this date field.
This is the first time I have been working on databases and I am trying to insert data using an object datasource but no data is being inserted and no exception is thrown. I'm not sure where I am going to wrong. I am putting user data into session variables and inserting the session variables into the dataacess class layer and have a try and exception but nothing being thrown. Any help would be really appreciated because I don't know even where to start looking with this or how I can get the error to be thrown. Please see some of my code below to give an idea of what I am doing
Object Access Class public void InsertCarPolicyHolder(PolicyHolderClass ph, CarInsuranceOptions options) {
I am trying to use the TableApapterManager.UpdateAll to insert values to master and child table. I had set the relation to cascade for update in the dataset and the HierarchicalUpdate to true. But stil when I run TableApapterManager.UpdateAll(dataset), I get a foriegn key violation error. Following is the code I used:
The error I get is "The INSERT statement conflicted with the FOREIGN KEY constraint "FK_MemPhones_Members". The conflict occurred in database "Family", table "dbo.Members", column 'i_memeberid'. The statement has been terminated."
generating logic for follwing:An option to add a range of computers based on tag numbers, for instance, user input 800101 and 800110 would add computers SYS800101, SYS800102, SYS800103, SYS 800104, SYS800105, SYS800106, SYS800107, SYS800108, SYS800109, and SYS800110. Currently the app adds a single computer at a time.Here I am using ASP.NET using C# and my backend in active directory. I had made the following code and the problem is when I enter the range like given above only the first computer in entered in the list and does not give me any error.
I been reading a bit about SQL injection and I want to be sure my code is lets say "safe" from it, I was planning on using RegExp validators to check the user input but another post in here suggested only using parametrized querys, well Im using them but I want to be sure my code is safe, is it?
have a form where I insert record via DetailView control. I have some string fields. For each string field (nvarchar in sql) I have defined the Default Value in the SQL SERVER (2008) as ''. Also I have added to each InsertParameter of the DetailsView a DefaultValue="".Yet still, if the user enters no value for one of the string fields, NULL is inserted into the table.
I am using Stored Procedure as my Insert/Update command in a FormView. The sp returns a value which I will need to use. How do I retrieve the value after doing an insert / update?
here is my code for selectiong some records from db table
string strSql = "select * from mtblNBD where SentTo=@SentTo and InternalStatus Is NULL order by DeadLine desc"; SqlCommand com = new SqlCommand(strSql, con); com.Parameters.Add("@SentTo", SqlDbType.NVarChar, 50).Value = (string)Session["uname"];
here I am using parameters for SenTo field but not for NULL so it is ok... or should I use parameters for this field where value is NULL , if yes then how can I use parameter for this
My problem is this "I have all the tools, VS 2005, 2008, 2010. I have every book, I have SQL server 2005 and 2008" I have all the tools, but I do not know what tool or technology to use when starting out learning all this. I juat do not know what book teaches what I need to do for something like below.
Here is my question:
I created an .ASPX webform that is to "Submit" to a SQL 2005 database. I gave this form to my DBA, and he has made up a Data Model. Now I have to figure out how to write the ASP.NET code so it will submit to the DB. My first issue is not knowing this:
1. "How do I loop through my CheckBox List", and then insert the values checked into a "Database Table" (Each Checkbox value MUST be a seperate row in the table, the DBA does not want a seperate column for each checkbox value)
2. The database is using stored procedures
3. My third issue is this: "I do not know "where" to put the "code". If you do resond to this,
Summary: I just need shown the code on how to "loop through" the CheckBox List on my form, and insert those values into a database table as seperate rows.
I have a formview that is working fine for with the exception of the username is not inserting on a new record. The username is visible on login so I know that is working. I'm attaching my sql code as well as the code behind as I don't know what I'm missing.
