Unlike field validation rules, record validation rules refer to other fields in the same table.
For field and record validation rules, the expression can't contain user-defined functions, domain aggregate or aggregate functions, the Eval function, or CurrentUser method, or references to forms, queries, or tables.
For controls, you can set the ValidationRule property to any valid expression. For field and record validation rules, the expression can't contain user-defined functions, domain aggregate or aggregate functions, the Eval function, or CurrentUser method, or references to forms, queries, or tables. In addition, field validation rules can't contain references to other fields. For records, expressions can include references to fields in that table.
Record (or table) validation rulesUse a record validation rule to control when you can save a record (a row in a table). Unlike field validation rules, record validation rules refer to other fields in the same table. You create record validation rules when you need to check the values in one field against the values in another. For example, suppose your business requires you to ship products within 30 days and, if you don't ship within that time, you must refund part of the purchase price to your customer. You can define a record validation rule such as [RequiredDate]<=[OrderDate]+30 to ensure that someone doesn't enter a ship date (the value in the RequiredDate field) too far into the future.
You can't set field or record validation rules for tables created outside Microsoft Access (for example, dBASE, Paradox, or SQL Server).
dBASE、Paradox、SQL Server など、Access 以外のデータベースで作成されたテーブルのレコードやフィールドには、入力規則を設定することができません。
