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 XeroDataReader 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 = "InitiateOAuth=GETANDREFRESH;"; using (XeroConnection conn = new XeroConnection(connectionString)) { XeroCommand cmd = new XeroCommand("SELECT * FROM Contacts WHERE ContactStatus = 'ACTIVE'", conn); XeroDataReader 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 = "InitiateOAuth=GETANDREFRESH;" Using conn As New XeroConnection(connectionString) Dim cmd As New XeroCommand("SELECT * FROM Contacts WHERE ContactStatus = 'ACTIVE'", conn) Dim rdr As XeroDataReader = 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
