Object Query Language (OQL) is a query language standard for object-oriented databases modeled after SQL. OQL was developed by the Object Data Management Group (ODMG). Because of its overall complexity no vendor has ever fully implemented the complete OQL. OQL has influenced the design of some of the newer query languages like JDOQL and EJB QL, but they can't be considered as different flavors of OQL. ==General rules== The following rules apply to OQL statements: * All complete statements must be terminated by a semi-colon. * A list of entries in OQL is usually separated by commas but not terminated by a comma(,). * Strings of text are enclosed by matching quotation marks. 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Object Query Language」の詳細全文を読む スポンサード リンク
