Procedure Parameters

The ProcedureParameters schema collection describes the stored procedure parameters.

Retrieving Stored Procedure Parameter Metadata

The ProcedureParameters schema collection contains information about the parameters of stored procedures.

To retrieve the ProcedureParameters schema collection, call the GetSchema method of the Dynamics365Connection class. Access the metadata in the DataTable object returned. The following example retrieves parameter information for all stored procedures:


String connectionString = "InitiateOAuth=GETANDREFRESH;OrganizationUrl=;Edition=Sales;";

using (Dynamics365Connection conn = new Dynamics365Connection(connectionString)) {
  DataTable table = conn.GetSchema("ProcedureParameters");
  foreach (DataRow row in table.Rows) {
    foreach (DataColumn col in table.Columns) {
      Console.WriteLine(col.ColumnName + "=" + row[col]);


Dim connectionString As [String] = "User=InitiateOAuth=GETANDREFRESH;OrganizationUrl=;Edition=Sales;"

Using conn As New Dynamics365Connection(connectionString)
  Dim table As DataTable = conn.GetSchema("ProcedureParameters")
  For Each row As DataRow In table.Rows
    For Each col As DataColumn In table.Columns
      Console.WriteLine(col.ColumnName + "=" + row(col))
End Using
