The main results in this paper as follows : first, a prototype of a shape - based image database retrieval system is completed, it can receive the query mode both by giving an example image and by sketching the desired object on the screen, second, five shape - based image retrieval methods are realized ; third, an algorithm based on triangulation for shape - based image retrieval is brought forward. in this algorithm, firstly, the edge of the original image is followed and the candidate corners in the original image are detected. then the counterpoints of the candidate corners in the result of edge follow are found, and the boundary corners whose counterpoints have been found are queued in the order of their counterpoints in edge follow
同時本文中主要完成了以下三方面的工作：完成了一個基於形狀特徵的圖象檢索的原型系統，可實現例子圖象或徒手繪草圖兩種查詢方式；實現了五種利用形狀特徵進行圖象檢索的具體方法，並對其進行了分析比較；並且在繼承將三角剖分引入形狀檢索的思想基礎上提出了利用三角剖分進行形狀檢索的一種新演算法：先對原圖象進行邊界跟蹤和角點檢測；然後尋找初始角點在邊界跟蹤中的對應點，並對找到對應點的角點按其對應點在邊界跟蹤中的順序進行排序；再對排序后的角點進行德洛內三角剖分，得到能表示目標真實形狀的三角形序列；最後計算三角形序列的角度直方圖作為形狀特徵，並進行相似性匹配。 -

Connected with query by example, a content - based visual multimedia query language is designed, in which semantics expression, object - oriented expression are combined. this language, on one hand, can provide a visual query interface, on the other hand, can implement content - based multimedia query
它將語義表達、面向對象的表示和圖像示例有機地結合起來，一方面可提供一個自然的圖形查詢介面，另一方面可結合多媒體的內容信息，實現基於內容的多媒體查詢。 -
Your users expect to be able to query across both tables to look up orders by customer, for example, and to add new order information
如果您的用戶期望可以同時查詢兩個表，以按客戶查找訂單並添加新的訂單信息。 -
Running a report under an account that has elevated permissions exposes your sql server to a security threat if the report query contains malicious transact - sql statements for example, statements that create unauthorized logons, modify or delete data, or introduce erroneous data, and the report is run by a user who has elevated permission on the server that hosts the data source
如果報表查詢包含惡意的transact - sql語句（例如，用於創建未經授權的登錄名、修改或刪除數據、或引入錯誤數據的語句） ，而且該報表由具有對承載數據源的服務器的提升權限的用戶運行，則使用具有提升權限的帳戶運行該報表將使sql server面臨安全隱患。 -
Create a query either by using a wizard or using a graphical method known as query by example ( qbe )
創建查詢的方法有兩種：一種是使用向導，另一種是使用稱為「通過示例查詢」 （ qbe ）的圖形方式。 -

We design an actual image retrieval system for the above retrieval method. the system is simple and convenient, and supports query by example and query by scanning
該系統具有可視性好，檢索直觀、方便的優點，可支持瀏覽查詢和示例查詢。 -
Wide character string processing functions are required by text - editing software - something that used to be regarded as problematic because of performance issues - it is perfectly possible simply to query the locale mechanism regarding the availability of a utf - 8 - based or any other locale and convert, for example, utf - 8 multibyte strings to the
寬度的字元串處理功能完全可以只查詢locale機制是否有基於utf - 8的locale ，或者是否有其他任何locale ，並將utf - 8這樣的多位元組字元串在應用程序內部轉換為 -

For example, a view based on a very complex query that returns only five rows for example, a group by query is costly to evaluate at the remote source
例如，基於一個非常復雜的、只返回5行的查詢（例如一個group by查詢）的視圖在遠程數據源上計算起來代價較高。 -
The following query returns the value for the cell referenced by the tuple specified in the previous example, 80, 450. 596. 98
