數據語句
英文
data statement-
So we extent its function by adding sqlquery expressions which contain sql. it gets results from queries by jdbc api and convert it into xml format. then it uses xquery complier to query in succession in order to integrate related databases
Xquery語言本身並不能實現該功能,所以我們對它進行擴展,增加嵌套sql語句的sqlquery表達式,使用jdbc來查詢sql語句,而將產生的結果轉換為xml文檔,再使用xquery編譯器來實現查詢要求,達到集成關系數據庫的目的。Audit database scope gdr event class occurs whenever a grant, revoke, or deny is issued for a statement permission by any user in microsoft sql server for database - only actions such as granting permissions on a database
每當microsoft sql server中的用戶發出針對語句權限的grant 、 revoke或deny時(僅限於數據庫操作,例如針對某個數據庫授予權限) ,都會發生However, data manipulation language and data definition language statements execute atomically
但是,數據操作語言( dml )和數據定義語言( ddl )語句會自動執行。If you a have a column that has a skewed data distribution, a histogram on it and if you are using bind variables against that column you may suffer from the same problem

第三章dc元數據語法和句法。從語言學角度對都柏林核心元數據的語法、句法進行了較完整的研究。根據都柏林核心元數據的語法特點,提出了將其句法分為語法句法和元數據句法兩類句法。Abstract : for a precise dataflow analysis within the framework of the computation function model, the logical relationship of branch conditions is represented as the coverage relationship of regions. in this paper, the authors discuss how to represent, compute and propagate the region, region of the conditional reference. meanwhile, the methods of resolving the nondeterminism caused by conditional branch statements are also presented in order to get more precise dataflow information
文摘:用計算函數模型進行精確的數據流分析,條件謂詞之間的邏輯關系被轉化為空間區域之間的覆蓋關系.該文討論在各種常見的程序構造下如何表示、計算和傳遞區域、區域,並在數據流分析過程中,利用區域、區域之間的覆蓋關系消除條件分支語句帶來的不確定性,以得到更精確的數據流信息Valid yet destructive statements such as deleting an entire payroll table, dropping a claims table or even inadvertently dropping an entire database can cause extended down time for your database applications
對于數據庫應用程序,有效但具破壞性的語句(比如刪除整個工資單表中的記錄、刪除索賠( claims )表,或者意外刪除整個數據庫)可能導致長期的停機時間。To design and execute statements written in the data mining extensions language
,可以設計並執行用數據挖掘擴展插件( dmx )語言所編寫的語句。The data mining extensions language provides statements that you can use to create, train, and use data mining models
數據挖掘擴展插件( dmx )語言提供了一些語句,您可以使用這些語句創建、定型和使用數據挖掘模型。The following topics describe how to fetch data and how to execute sql statements and stored procedures
以下主題介紹如何獲取數據以及如何執行sql語句和存儲過程。Indicates that the database engine will convert the original text of the create function statement to an obfuscated format
指示數據庫引擎會將alter procedure語句的原始文本轉換為模糊格式。The user who executed the create function statement has references permission on the database objects that the function references
執行create function語句的用戶對該函數引用的數據庫對象具有references權限。Traditional coding algorithms are based on simple n - gram models. those distant constraints and some redundancies in natural language, such as word order redundancies, semantic redundancies and syntactic redundancies, are neglected in the n - gram models. in order to find and reduce those redundancies, we need more intelligent algorithms based on more effective models
通用無損數據編碼是數據壓縮領域的一個重要的分支,現有的無損數據編碼方法大多是基於n - gram模型的, n - gram模型忽略了自然語言中的遠距離約束和諸如詞序冗餘、語義冗餘、句法冗餘等冗餘,為了找出並減少這些冗餘,需要更有效的語言模型和更智能的演算法。The programming statements that perform operations in the database, including calling other procedures
執行數據庫操作(包括調用其他過程)的編程語句。Contain programming statements that perform operations in the database, including calling other procedures
包含用於在數據庫中執行操作包括調用其他過程的編程語句。The main research works and specific contributions found in this thesis covers the following aspects : 1. an appropriate data model for xml - based semistructured data is required before a dbms can be built

出現在當前數據庫內的transact - sql存儲過程、標量函數、多語句表值函數或transact - sql dml觸發器的上下文中。If you are working with an odbc or ole db database, parameters in a parameterized statement are not named and instead are specified with the placeholder character
如果使用odbc或ole db數據庫,則不對參數化語句中的參數命名,而是使用佔位符「 ? 」( 2 ) in order to validate the efficiency of algorithm, this paper design and implement a testing, platform rule processor based on sql server. the main function of the processor is to translate the first order logic rule into embedded - sql programs, which make sql server dbms possess the capability in expressing recursive query with logic language
( 2 )為驗證演算法的有效性,該文設計實現了一個測試平臺? ?基於sqlserver的規則處理器,其主要功能為自動把一階邏輯規則轉換為含有sql語句的過程代碼,這使得sqlserver數據庫管理系統有了用邏輯數據語言表示遞歸查詢的能力。分享友人
