getdate()
SQL Serverの機能を使用する MS Access のリンク テーブルに対するクエリがあります。ただし、クエリを実行しようとすると、次のエラーが発生します。
関数内の未定義関数 GetDate
SQL Server T-SQL 構文を使用できるリンク テーブルを作成するにはどうすればよいですか? これは a と呼ばれてpass through query
いるようですが、リンク テーブルの接続をパス スルー クエリとして使用するように設定する方法がわかりません。
現在 Access 2010 を使用しています。クエリは次のとおりです。
select getdate()
それが役立つ場合は、SQL Server へのテーブル リンクを生成する次の vba コードを使用しました。
Function LinkTable(LinkedTableAlias As String, Server As String, Database As String, SourceTableName As String, OverwriteIfExists As Boolean, Username As String, Password As String)
