Question

I am using SQL Server CE database and C# language. I have a table with a bigint typed column. When I use a foreach loop for inserting some data :

 foreach (int alt in lsAltitudes)
 {
     Query =   "INSERT INTO Altitude (DataID, Height) " +
                "VALUES (@ID, @Height) ";

     using (var SQLCmd = new SqlCeCommand(Query))
     {
         SQLCmd.Parameters.Add("@ID", DataID);
         SQLCmd.Parameters.Add("@Height", alt);
         con.CeExecuteNonQuery(SQLCmd);
     }
 }

Getting an error :
Parameterized query ‘INSERT INTO Altitude (DataID, Height) VALUES (@ID, @Height) ‘ expects a parameter value which was not supplied.

My DataID variable’s type is long by the way. I think it’s somehow about converting bigint and a long value. But I’m not sure.

If I’m not mistaken it should be so

using (var SQLCmd = new SqlCeCommand(Query)) 
{ 
     SQLCmd.Parameters.Add("@ID", SqlDbType.BigInt).Value = DataID; 
     SQLCmd.Parameters.Add("@Height", SqlDbType.Int).Value = alt; 
     con.CeExecuteNonQuery(SQLCmd); 
}
