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 JSONConnection class. Access the metadata in the DataTable object returned. The following example retrieves parameter information for all stored procedures:

C#

String connectionString = "DataModel=Relational;URI=C:\people.json";

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

VB.NET

Dim connectionString As [String] = "User=DataModel=Relational;URI=C:\people.json"

Using conn As New JSONConnection(connectionString)
  conn.Open()
  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))
    Next
  Next
End Using

Columns Returned

The columns of the schema collection are the following:
