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 { EmployeeId = <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;OAuthClientID=YourClientId;OAuthClientSecret=YourClientSecret;CompanyId=YourCompanyId;"; using (PaylocityConnection connection = new PaylocityConnection(connectionString)) { int rowsAffected; PaylocityCommand cmd = new PaylocityCommand("DELETE FROM Employee WHERE EmployeeId = @myEmployeeId", connection); cmd.Parameters.Add(new PaylocityParameter("myEmployeeId","1234")); rowsAffected = cmd.ExecuteNonQuery(); }
VB.NET
Dim connectionString As [String] = "InitiateOauth=GETANDREFRESH;OAuthClientID=YourClientId;OAuthClientSecret=YourClientSecret;CompanyId=YourCompanyId;" Using connection As New PaylocityConnection(connectionString) Dim rowsAffected As Integer Dim cmd As New PaylocityCommand("DELETE FROM Employee WHERE EmployeeId = @myEmployeeId", connection) cmd.Parameters.Add(New PaylocityParameter("myEmployeeId", "1234")) rowsAffected = cmd.ExecuteNonQuery() End Using
