    <p>Instead of declaring one variable for each tag in the file, you may want to try to iterate over all them, extracting the name and the value for each one and composing the SQL statement at runtime from those, no matter what they are. Try something like this:</p> <pre><code>IEnumerable&lt;XElement&gt; items = d.Descendants("level").Elements(); string names = string.Empty; string values = string.Empty; foreach (XElement item in items) { names += item.Name + ","; values += "@" + item.Name + ","; IDbDataParameter parameter = datacommand1.CreateParameter(); parameter.ParameterName = "@" + item.Name; parameter.DbType = DbType.String; parameter.Value = item.Value; datacommand1.Parameters.Add(parameter); } datacommand1.CommandText = "INSERT INTO MyTable (" + names.Substring(names.Length - 1) + ") VALUES (" + values.Substring(values.Length - 1) + ");"; datacommand1.ExecuteNonQuery(); </code></pre> <p>This builds the command on the fly, based on the XML structure, and fills its parameters with the data there. But doing so relies on the fact that the table structure will be exactly the same as in the file, and still needs manual schema updating when the structure changes, but as long as they're in sync it should be fine.</p> <p><strong>EDIT</strong></p> <p>About datatypes, there are 2 choices I can think of. Leave as it is, sending everything as strings no matter what, and rely on the DB engine to parse, validate and turn those into numbers (depending on what DB you're using, that may be possible or not, but I guess it's not rare to see). Or modify the code to separate the special fields apart from the loop (and excluding from it) and add those one by one, specifying their types accordingly. This is easy to do if the numeric columns are fixed, like the ID, and everything else is text.</p>

    1. COwell, that's great! but, though i try to test your code, while making even all my database table fields of text type (not integer), i still face the message:(An unhandled exception of type 'System.Data.OleDb.OleDbException' occurred in System.Data.dll Additional information: Syntax error in INSERT INTO statement.)

    2. COOK, seems like the SQL statement is not properly constructed (that's what happens when you don't test before posting :D). Try single stepping when it builds the command to see where it has an error, most likely it would be a comma or a wrong parameter.

    3. COi completely understand the whole idea now; but, i'll be very grateful if you can detect where the error exactly, i just can find it's in the sql statement, but not able to detect it, please help

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
