Result Sets
You can access the same column information about the results of a query that you can for table schemas. See Columns for the columns returned.
Retrieving Result Set Metadata
You can use the GetSchemaTable method of the SharePointDataReader to retrieve result set metadata. Call GetSchemaTable after calling ExecuteReader.
Each row of the DataTable describes a column in the query's result.
C#
string connectionString = "User=MyUserAccount;Password=MyPassword;Auth Scheme=NTLM;URL=http://sharepointserver/mysite;"; using (SharePointConnection conn = new SharePointConnection(connectionString)) { SharePointCommand cmd = new SharePointCommand("SELECT * FROM Calendar WHERE Location <> 'Chapel Hill'", conn); SharePointDataReader rdr = cmd.ExecuteReader(); DataTable schemaTable = rdr.GetSchemaTable(); foreach (DataRow row in schemaTable.Rows) { foreach (DataColumn col in schemaTable.Columns) { Console.WriteLine("{0}: {1}", col.ColumnName, row[col]); } } }
VB.NET
Dim connectionString As String = "User=MyUserAccount;Password=MyPassword;Auth Scheme=NTLM;URL=http://sharepointserver/mysite;" Using conn As New SharePointConnection(connectionString) Dim cmd As New SharePointCommand("SELECT * FROM Calendar WHERE Location <> 'Chapel Hill'", conn) Dim rdr As SharePointDataReader = cmd.ExecuteReader() Dim schemaTable As DataTable = rdr.GetSchemaTable() For Each row As DataRow In schemaTable.Rows For Each col As DataColumn In schemaTable.Columns Console.WriteLine("{0}: {1}", col.ColumnName, row(col)) Next Next End Using
