DELETE ステートメント
テーブルから情報を削除するには、DELETE ステートメントを使用します。
DELETE 構文
DELETE ステートメントには、次の例に示すように、FROM 句のテーブル名とWHERE 句の行の主キーが必要です。
<delete_statement> ::= DELETE FROM <table_name> WHERE { AccountId = <expression> } [ { AND | OR } ... ]
<expression> ::=
| @ <parameter>
| ?
| <literal>
次の例に示すように、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る行数を取得できます。
C#
String connectionString = "InitiateOAuth=GETANDREFRESH;OrganizationUrl=https://api.businesscentral.dynamics.com/v1.0/api/v1.0"; using (D365BusinessCentralConnection connection = new D365BusinessCentralConnection(connectionString)) { int rowsAffected; D365BusinessCentralCommand cmd = new D365BusinessCentralCommand("DELETE FROM Accounts WHERE AccountId = @myAccountId", connection); cmd.Parameters.Add(new D365BusinessCentralParameter("myAccountId","'00000000-0000-0000-0000-000000000000'")); rowsAffected = cmd.ExecuteNonQuery(); }
VB.NET
Dim connectionString As [String] = "InitiateOAuth=GETANDREFRESH;OrganizationUrl=https://api.businesscentral.dynamics.com/v1.0/api/v1.0" Using connection As New D365BusinessCentralConnection(connectionString) Dim rowsAffected As Integer Dim cmd As New D365BusinessCentralCommand("DELETE FROM Accounts WHERE AccountId = @myAccountId", connection) cmd.Parameters.Add(New D365BusinessCentralParameter("myAccountId", "'00000000-0000-0000-0000-000000000000'")) rowsAffected = cmd.ExecuteNonQuery() End Using
