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=https://abc.rightnowdemo.com;User=user;Password=password;";
using (OracleServiceCloudConnection connection = new OracleServiceCloudConnection(connectionString)) {
  int rowsAffected;
  OracleServiceCloudCommand cmd = new OracleServiceCloudCommand("UPDATE Accounts SET LookupName='John' WHERE Id = @myId", connection);
  cmd.Parameters.Add(new OracleServiceCloudParameter("myId","6"));
  rowsAffected = cmd.ExecuteNonQuery();
}

VB.NET

Dim connectionString As [String] = "Url=https://abc.rightnowdemo.com;User=user;Password=password;"
Using connection As New OracleServiceCloudConnection(connectionString)
  Dim rowsAffected As Integer
  Dim cmd As New OracleServiceCloudCommand("UPDATE Accounts SET LookupName='John' WHERE Id = @myId", connection)
  cmd.Parameters.Add(New OracleServiceCloudParameter("myId", "6"))
  rowsAffected = cmd.ExecuteNonQuery()
End Using
