名稱:Paradox Query 版本:V1.0 原始程式:需購買或註冊 適用:(D3)(D4)(D5) 版權種類:分享軟體(Shareware) 作者:Abacadabra SW 原創公司:Abacadabra SW 出處網址:http://home.wanadoo.nl/abacadabra/index.html 說明: ParadoxQuery is a component that enables you to use standard SQL to create paradox tables. You can also call it extended local SQL. You don't have to call any complex BDE function from now on. ParadoxQuery enables you to declare

• foreign key constraints,
• null constraints,
• unique constraints,
• default values and
• check constraints

the same way you would do for SQL databases. Both column and table constraints are supported.
Declaration of foreign keys will result in Referential Integrity checks, declaration of a not null constraint will result in a required field, declaration of unique constraints can result in a unique index and declaration of a check constraint will result in one or more validity checks.
