ADO.NET Provider for Reckon

Build 23.0.8839

GETDELETED Statements

You can issue the GETDELETED query to retrieve all records deleted from the live data for the time range specified. This query accepts a datetime value as a filter, as shown in the following example:

GETDELETED FROM <table_name> WHERE <search_condition>

<search_condition> ::= 
  {
    <expression> { = | < | <= | > | >= } [ <expression> ] 
  } [ { AND | OR } ... ]

<expression> ::=
  | @ <parameter> 
  | ?
  | <literal>
  

C#

String connectionString = "User=test;Password=test;URL=http://localhost:8166;";
using (ReckonConnection connection = new ReckonConnection(connectionString)) {
  ReckonCommand cmd = new ReckonCommand("GETDELETED FROM Customers WHERE TimeModified >= '2013-01-01'", connection); 
  ReckonDataReader rdr = cmd.ExecuteReader();
  while (rdr.Read()) {
    Console.WriteLine(rdr["Id"].ToString());
  }
}

VB.NET

Dim connectionString As [String] = "User=test;Password=test;URL=http://localhost:8166;"
Using connection As New ReckonConnection(connectionString)
  Dim cmd As New ReckonCommand("GETDELETED FROM Customers WHERE TimeModified >= '2013-01-01'", connection)
  Dim rdr As ReckonDataReader = cmd.ExecuteReader()
  While rdr.Read()
    Console.WriteLine(rdr("Id").ToString())
  End While
End Using
Note: By putting a CACHE command in front of the query, you can update the cache to remove all values that have been deleted from the data source, as shown in the following example:
CACHE GETDELETED FROM [TableName] WHERE TimeModified >= '2013-01-01' AND TimeModified <= '2013-02-01'
