Hi,

I have one problem with No value given for one or more required parameters
error.

I am using OleDb connection, C# and ASP.NET

I have used Edit controls (txtID, txtLName)...

Code is following:
....
String insertCmd = "insert into Authors (au_id, au_lname, au_fname, phone,
address, city, state, zip, contract) values (@Id, @LName, @FName, @Phone,
@Address, @City, @State, @Zip, @Contract)";

OleDbCommand myCommand = new OleDbCommand(insertCmd, thisConnection);

myCommand.Parameters.Add(new OleDbParameter("@Id", OleDbType.VarChar, 11));

myCommand.Parameters["@Id"].Value = txtID.Text;
/*Server.HtmlEncode(txtID.Text);*/

myCommand.Parameters.Add(new OleDbParameter("@LName", OleDbType.VarChar,
40));

myCommand.Parameters["@LName"].Value = txtLName.Text; /*
Server.HtmlEncode(txtLName.Text); */


myCommand.Connection.Open();

myCommand.ExecuteNonQuery();

I am not sure what is wrong and why this error has occured?

Thanks

Well, you've specified 9 parameters in the query, and only filled in
values for 2 of them. What did you expect to happen about the other 7?

Thanks Jon.
I understand but look this.
When i use following line of code
String insertCmd = "insert into Authors (au_id, au_lname) values (@Id,
@LName)";

OleDbCommand myCommand = new OleDbCommand(insertCmd, thisConnection);

myCommand.Parameters.Add(new OleDbParameter("@Id", OleDbType.VarChar, 11));

From a bit of brief digging on the web, that error could be to do with:

o Impersonation
o Network access
o A read-only file

What exactly is your situation? What kind of database are you talking
to? Is it local or remote?

mp,
Since this looks like pubs from SQL 2000 you have three more 'required'
fields to fill in as au_fname, phone, and contract are specified as NOT NULL
and do not have default values. So the insert will be rejected as violating
table constraints.

Thanks,

I don't know what imperonation is. I have MS Access Db and local connection.

Complete code is:
@OleDbConnection thisConnection = new OleDbConnection(
@"Provider=Microsoft.Jet.OLEDB.4.0;" +
@"Data Source=" +
@"C:\base\pubs.mdb");

//String insertCmd = "insert into Authors (au_id, au_lname, au_fname, phone,
address, city, state, zip, contract) values (@Id, @LName, @FName, @Phone,
@Address, @City, @State, @Zip, @Contract)";
String insertCmd = "insert into Authors (au_id, au_lname) values (@Id,
@LName)";
OleDbCommand myCommand = new OleDbCommand(insertCmd, thisConnection);
myCommand.Parameters.Add(new OleDbParameter("@Id", OleDbType.VarChar, 11));
myCommand.Parameters["@Id"].Value = txtID.Text;
/*Server.HtmlEncode(txtID.Text);*/
myCommand.Parameters.Add(new OleDbParameter("@LName", OleDbType.VarChar,
40));
myCommand.Parameters["@LName"].Value = txtLName.Text; /*
Server.HtmlEncode(txtLName.Text); */
myCommand.Connection.Open();
myCommand.ExecuteNonQuery();
myCommand.Connection.Close();

BindGrid(); <-- method works properly

No this is not pubs from SQL 2000. It is my own MS access database with
"same" table inide. I am not sure is the same but all columns are text type.
There is no required filelds.


Thanks

Is it possible that your string LName contains some invalid characters?

mp,
I'd then check to make sure all the ones you aren't filling in have
allow zero length set to Yes as well as this can cause problems too.
