  4. If you re migrating to ibm db2 universal database from a database that supports bit and boolean operations and functions, you may be wondering how to handle these types and functions in db2. our author offers a method that includes table creation with columns of the bit - like or boolean data types using constraints or triggers, and a set of user - defined functions to support bitwise and boolean operations that imitate bit or boolean data - type behavior

    本文作者提出了一種方法，這個方法中包括使用約束條件或觸發器創建的表，表中包含類似於位（ bit - like ）的數據類型的列或布爾數據類型的列；該方法還包含一組用戶定義函數（ udf ） ，用於支持模仿位數據或布爾數據類型的行為的逐位運算和布爾運算。
  5. This article offers a method that includes table creation with columns of the bit - like or boolean data type, using constraints or triggers, and a set of user - defined functions udfs to support bitwise and boolean operations for columns that imitate bit or boolean data type behavior

    本文將提供一種方法，該方法包括使用約束條件或觸發器創建了一個表，表中包含類似於位（ bit - like ）或布爾數據類型的列；該方法還包括一組用戶定義函數（ udf ） ，用於支持模仿位數據或布爾數據類型的行為的逐位運算和布爾運算。

  7. Integration services can automatically suggests the most appropriate data types based on the first 100 rows of data. you can also change these suggestion options to sample more or less data, to specify the default data type for integer or boolean data, or to add spaces as padding to string columns

    Integration services將根據前100行數據自動建議數據類型，但您可以通過更改建議選項來增加和減少取樣數據，指定整數數據或布爾數據的默認數據類型，或添加作為填充量添加到字元串列中的空格。
  8. In this paper, a new type algebra is introduced, it is the algebraic abstract of mpm system just as boolean algebra is the algebraic abstract of 2 - valued propositional calculus. the main purpose of this paper is to investigate the various properties of the new algebra. in addition, this paper constructs an axiom set based on the medium logic propositional calculus system mpm, and gives a proof of its completeness

    本文通過對mpm中介邏輯命題演算系統進行代數抽象，建立了一個新的代數系統，討論了該代數系統的性質，並利用該代數系統的代數性質構造了中介命題演算系統mpm上的一個公理完備集合，使用該公理集合可以方便的推導出mpm上的等值和互推公式，這對于處理不完全信息數據庫的查詢優化有著重要作用。

    對于boolean比較，結果的數據類型為
  13. Versa also provides facilities - such as full boolean logic and set operations, transitive operations, aggregates, substring matching, and other core data type manipulation - that are lacking in many other rdf query systems

    Rdf模型是圖形結構，該結構可以非常簡單也可以令人難以置信的復雜。事實上，極端情況下， semantic web的設想是要創建至少同當前web一樣大的rdf模型。
  14. We also obtain similar results on nearly reducible boolean matrices. we determine the maximum values of the first type of indices of convergence of n x n boolean matrices, reducible matrices, critically reducible matrices respectively, characterize the corresponding extreme matrices

    對第一種類型的廣義冪斂指數，我們得到了n n布爾矩陣類， n n可約布爾矩陣類， n n臨界可約布爾矩陣類的這種指數的最大值，刻畫了極矩陣。

    可空布爾值類似於sql中使用的布爾變量類型。為了確保
  18. For an example of when you might use a nullable type, consider how an ordinary boolean variable can have two values : true and false

    有關可能使用可空類型的示例，請考慮普通的布爾變量如何能夠具有兩個值： true和false 。
