SQL Server 2005 - Get XML Field to File; some xml fields to their own files

My string structure looks like ID bigint, ScanRept XML

I want to end up with a file named 4.xml containing only xml from the ScanRept column where the id is 4.

I don't want to do this interactively (by going to Studio Manager, finding the line, right clicking on the field and doing Save AS) - what will I do if I can't find a better way,

I have C #; if it is doable with sqlcmd this is my preference (because there are likely to be many changes that I cannot foresee right now).

There is probably a better way to do this ... but without testing, something like this might work. FROM#



SqlDataAdapter adapter = new SqlDataAdapter("SELECT ID, ScanRept FROM TableName", "connString");
DataTable dt = new DataTable();
adapter.Fill(dt);

foreach (DataRow row in dt.Rows)
{
    string type = row["ID"].ToString();
    string location = "C\\" + type + ".xml";
    string xml = row["ScanRept"].ToString();
    XmlTextWriter writer = new XmlTextWriter(location, null);
    writer.WriteString(xml);
    writer.Flush();
    writer.Close();
}

Command line approach with bcp

:

bcp "SELECT ScanRept FROM <DBName>.dbo.<TableName> WHERE ID = 4" queryout 4.xml -c -S<ServerName> -U<UserName> -P<Password>

or for reliable connections

bcp "SELECT ScanRept FROM <DBName>.dbo.<TableName> WHERE ID = 4" queryout 4.xml -c -S<ServerName> -T


Command line approach with sqlcmd

:

sqlcmd -U<Username> -P<Password> -S<ServerName> -h -1 -Q "SET NOCOUNT ON SELECT ScanRept FROM <DBName>.dbo.<TableName> WHERE ID = 4;" -o 4.xml

or for reliable connections

sqlcmd -E -S<ServerName> -h -1 -Q "SET NOCOUNT ON SELECT ScanRept FROM <DBName>.dbo.<TableName> WHERE ID = 4;" -o 4.xml

Thank you both - good tips

Pano, it truncates after a certain length - is that 258 characters?

Toytown that works besides writer.WriteRaw () is what I need, or else it encodes the XML markup to make it valid data, for example turns into an lt ampersand with a semicolon

So far, I cant get anything but one long xml stream (no indentation, no line breaks). I'm not sure if there is any white space formatting in my data, but I know when I right click on a field in SSMS it brings up the MS XML editor showing everything is formatted pretty.

Okay, as the French say, "This damn XML is a pain in French Too-SHEE." Both of your comments are helpful, and I will vote on your answers as soon as I register this public identity thing.

Here's another approach that would allow him to write it pretty like a hot girl franch:

        string IRIXno = args[0] ;

        string connectionString ;

        string query = "Select ID, Report FROM Reports WHERE id =" + IRIXno;

        try

        {

            connectionString = ConfigurationSettings.AppSettings["ConnectionString"];

        }

        catch

        {

            Console.WriteLine("YOur connection string isn't set or something.");

            return;

        }

        SqlConnection conn = new SqlConnection(connectionString);

        conn.Open();

        SqlCommand sqlComm = new SqlCommand(query, conn);

        sqlComm.CommandType = CommandType.Text;

        SqlDataReader reader = sqlComm.ExecuteReader();

        reader.Read(); // one and only row

        XmlDocument doc = new XmlDocument();

        XmlReader xmlReader = reader.GetSqlXml(1).CreateReader() ;//second column is our guy

        doc.Load(xmlReader); 


        string outfile = "H:\\" + IRIXno + ".xml";

        doc.Save(outfile) ;
