ADO.NET Provider for Dynamics 365 Finance and Operations

Build 21.0.7930

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 D365FinOpDataReader 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;OrganizationUrl=https://myaccount.operations.dynamics.com/;";

using (D365FinOpConnection conn = new D365FinOpConnection(connectionString)) {
  D365FinOpCommand cmd = new D365FinOpCommand("SELECT * FROM Accounts WHERE Name <> 'MyAccount'", conn);
  D365FinOpDataReader 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;OrganizationUrl=https://myaccount.operations.dynamics.com/;"

Using conn As New D365FinOpConnection(connectionString)
  Dim cmd As New D365FinOpCommand("SELECT * FROM Accounts WHERE Name <> 'MyAccount'", conn)
  Dim rdr As D365FinOpDataReader = 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
