UPDATE ステートメント

既存のレコードを変更するには、UPDATE ステートメントを使用します。

Update 構文

UPDATE 構文はカンマ区切りのカラムをインプットとして取り、SET 句のname-value ペアを新しいカラム値として取ります。

UPDATE <table_name> SET <select_statement> | {<column_reference> = <expression> [ , ... ]} WHERE { Id = <expression>  } [ { AND | OR } ... ] 

<expression> ::=
  | @ <parameter> 
  | ?
  | <literal>
ExecuteNonQuery メソッドを使って、データ操作コマンドを実行し影響を受けた行を取得できます。

C#

String connectionString = "URL=http://myserver:7048;User=myserver\Administrator;Password=admin;ServerInstance=DYNAMICSNAV71;";
using (DynamicsNAVConnection connection = new DynamicsNAVConnection(connectionString)) {
  int rowsAffected;
  DynamicsNAVCommand cmd = new DynamicsNAVCommand("UPDATE Customer SET Contact='John' WHERE Id = @myId", connection);
  cmd.Parameters.Add(new DynamicsNAVParameter("myId","http://myserver:7048/DynamicsNAV71/OData/Customer('01234567')"));
  rowsAffected = cmd.ExecuteNonQuery();
}

VB.NET

Dim connectionString As [String] = "URL=http://myserver:7048;User=myserver\Administrator;Password=admin;ServerInstance=DYNAMICSNAV71;"
Using connection As New DynamicsNAVConnection(connectionString)
  Dim rowsAffected As Integer
  Dim cmd As New DynamicsNAVCommand("UPDATE Customer SET Contact='John' WHERE Id = @myId", connection)
  cmd.Parameters.Add(New DynamicsNAVParameter("myId", "http://myserver:7048/DynamicsNAV71/OData/Customer('01234567')"))
  rowsAffected = cmd.ExecuteNonQuery()
End Using
