[Code]....
I pass the spIsFemale by using an enum, here is the Person Class with function.
[Code]....
I get an error that column isFemale is not valid. The isFemale column is a bit type. If it's a 1, it's a female, if 0 male. this is more of a test area and I'm trying to update records or create new one's if the name does not exist.II am new to C # and I am just trying to learn new ideas and methods within C sharp.

I want to import a spreadsheet into SQL. The import/export wizard forces Column A to be a double. In Excel, the column is formatted as text. When I try to convert from double to text/varchar/nvarchar, the import process fails. Why can't I convert a number to text in SQL?

I attempted to change a table columns data type and in the process caused a lot of issues. I had a date column in one of my tables and stupidly changed it from varchar to date. When I tried to run queries on it I keep getting the 'cant find column 3 error'. Now that tables structure is :
[Code]...
So column 4 is actually the date column. All other queries work for this table. I then tried to change it back and then copied all data to a new table and now I am using the new table and converting the dates as needed but I am still getting the error.
SELECT * FROM postlinks WHERE postlinks.date >= CONVERT(datetime,CONVERT(varchar(10),GetDate(),112))

I read a CSV file into a DataTable.The DataTable in the first image shows each column and type.The types are exactly what they are supposed to be and the data loaded all the rows it was supposed to load.From the second screen shot you can see the database table. SqlBulkCopy is supposed to map column names to database columns by default.According to that logic each column matches up exactly to the database and the column types also match.However,when I run the command it errors on the first row with:
"The given value of type String from the data source cannot be converted to type decimal of the specified target column."
Here is the StackTrace:
"at System.Data.SqlClient.SqlBulkCopy.ConvertValue(Object value, _SqlMetaData metadata) at System.Data.SqlClient.SqlBulkCopy.WriteToServerInternal() at System.Data.SqlClient.SqlBulkCopy.WriteRowSourceToServer(Int32 columnCount) at
[code]...
Anyone have any ideas why this will not import correctly?

I have been in the process of updating my code with security methods, and I've been learning this from [URL] (or "Security Guidelines: ASP.NET 2.0"). In the middle of the page under "When Constructing SQL Queries, Use Type Safe SQL Parameters" it says "Use type safe parameters when constructing SQL queries to avoid possible SQL injection attacks that can occur with unfiltered input". Now, what they suggested was to use code like:
"DataSet userDataset = new DataSet();
SqlDataAdapter myCommand = new SqlDataAdapter(LoginStoredProcedure", connection);
myCommand.SelectCommand.CommandType = CommandType.StoredProcedure;
myCommand.SelectCommand.Parameters.Add("@au_id", SqlDbType.VarChar, 11);........"
But, I was already using code like:
"var dataSource = (SqlDataSource)form1.FindControl("sqlDataSource5") ;
dataSource.UpdateParameters.Add("someVal", val);"
So now, to use type safe parameters, I decided to include it like:
"var dataSource = (SqlDataSource)form1.FindControl("sqlDataSource5") ;
dataSource.UpdateParameters.Add("@someVal", DbType.Int16, val);
dataSource.UpdateParameters["@someVal"].Size = 1;"
So, that would be how I would modify my current code base to use type safe parameters in sql updating/inserting.
Getting to my actual question, as it was said "Use type safe parameters when constructing SQL queries to avoid possible SQL injection attacks that can occur with unfiltered input". First off, this suggests that this should apply to unfiltered input. Also, in their example they only did this for an ID.
So, what I'd like to know, when it comes to "unfiltered input", does this mean as long as the input is unfiltered I must use type safe parameters, or even filtered input shall have this (just to be sure), like, input that has been ran through a regularexpression check? Shall I do this for all values I insert/update into the database, or just IDs and important things?
The way I see it right now is that it would be a good precaution to just do type safe checks on everything (literally) that updates/inserts into the database just to be extra safe. But, I really am unsure if this is really the best idea, because if I did, would this possibly cause overprocessing of information? Can this cause too much strain on server resources? If my fears serve true, what would be a good suggestion of how I could implement this properly without having to worry about what I said?

I want to Update Column of a Table where ColumnName will be DropDown.SelectedValue. Example: A set of RECORDS will be displayed from a Customer Table where CUstNo ='1234' and City= 'Chicago' and Grade ='B' Once displayed I want to Update the grade to 'A' of all those customers from the above criteria. In My case I have like 100 Columns, so in where Clause Column Names will be selected from a DropDown. In My Query, Update Customer SET ColumnName= 'some value' where ColumnName ='ActualValue' So how can I pass the ColumnName which is Dropdown Selected Value. I believe I can't give as Update Customer SET DropDown.SelectedValue = 'some value' where DropDown.SelectedValue ='ActualValue' how can I resolve this ?...

I get the error - Conversion from type 'DBNull' to type 'Integer' is not valid. - on the line.....
Dim newid As Integer = e.Command.Parameters("@latestRowId").Value.........in vb code behind.
I have the identical code for another page with the exception of the field names and it works fine. The only thing I did differently, as far as I know, is I copied the asp and code behind from the page that works into this page and manually changed the field and table names. I don't know what the problem is. Does anyone see any problems?

I have an Interface that has its concrete class defined via a factory. Because of this I found no way to use the Interface tpye directly in my LINQ quesry so I had to use the concrete class types to creat a generic list. The LINQ query works but after calling.ToList() on the LINQ query result I get a List(of MyConcreteClass), but I need a List(of IMyConcreteClass). I have tried everything I can find: .Cast, Ctype, implicit casting, etc. but I always get back one of the (2) messages (depending on if I attempt to cast)message:
"Unable to cast object of type 'System.Collections.Generic.List`1[MyConcreteClass]' to type 'System.Collections.Generic.IEnumerable`1[IMyConcreteClass]'."
...or
"Unable to cast object of type '<CastIterator>d__aa`1[IMyConcreteClass]' to type 'System.Collections.Generic.List`1[MyConcreteClass]'."

I am making a website to store invoices so i can mail them to clients. So i got a table for clients, invoices and one with invoice products/services. When an invoice has no products/services added to them and it returns null i get the error "the null value cannot be assigned to a member with type System.Decimal which is a non-nullable value type."
I just started with linq. Before i always used mysql. Mostly i just had to call data from 1 table so forgive me if my linq query isn't really correct.
Dim invoices = From i In db.invoices _
Group Join p In db.products On i.id Equals p.invoiceId Into invoiceProducts = Group _
Select New With {i.client.naam, i.titel, (From iP In invoiceProducts Select iP.prijs).Sum}
i show the client's name, the title of the invoice and the total amount the clients will need to pay for products and services.

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?

This is my programs complete code, the only problem is i want to fix the amount of decimal places that show up in my gridview. The problem is if i do this on the asp side the location of the column gets thrown off and the column is duplicated. I figured if i just remade the table on the asp side it would work only problem is if i remove the sql for that particular column the asp side column cannot get data.
