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 { GoalHeadingId = <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 = "InitiateOAuth=GETANDREFRESH;OrganizationUrl=https://myaccount.operations.dynamics.com/;Edition=Sales;"; using (Dynamics365Connection connection = new Dynamics365Connection(connectionString)) { int rowsAffected; Dynamics365Command cmd = new Dynamics365Command("UPDATE GoalHeadings SET GoalHeadingId='John' WHERE GoalHeadingId = @myGoalHeadingId", connection); cmd.Parameters.Add(new Dynamics365Parameter("myGoalHeadingId","'test'")); rowsAffected = cmd.ExecuteNonQuery(); }
VB.NET
Dim connectionString As [String] = "InitiateOAuth=GETANDREFRESH;OrganizationUrl=https://myaccount.operations.dynamics.com/;Edition=Sales;" Using connection As New Dynamics365Connection(connectionString) Dim rowsAffected As Integer Dim cmd As New Dynamics365Command("UPDATE GoalHeadings SET GoalHeadingId='John' WHERE GoalHeadingId = @myGoalHeadingId", connection) cmd.Parameters.Add(New Dynamics365Parameter("myGoalHeadingId", "'test'")) rowsAffected = cmd.ExecuteNonQuery() End Using
