Efficient execution of multiple queries on deep memory hierarchy 多存儲層次中多個查詢的高效執(zhí)行
Walkthrough : creating a tableadapter with multiple queries >演練:創(chuàng)建帶有多個查詢的tableadapter
Each query hint can be specified only one time, although multiple query hints are permitted 每個查詢提示只能指定一次,但允許指定多個查詢提示。
With a built-in connection object and the ability to contain multiple queries 早期版本的visualstudio的用戶可以將tableadapter視為具有內(nèi)置連接對象并能夠包含多個查詢的
Unlike standard data adapters, tableadapters can contain multiple queries to fill their associated data tables 與標(biāo)準(zhǔn)數(shù)據(jù)適配器不同,tableadapter可以包含多個查詢,以填充其關(guān)聯(lián)數(shù)據(jù)表。
29 zhang y, chen z, zhou y . efficient execution of multiple queries on deep memory hierarchy full version 本文下一步需要考慮的是,minitasking如何與現(xiàn)有的數(shù)據(jù)庫管理系統(tǒng)的查詢執(zhí)行引擎相結(jié)合。
20 o gorman k, agrawal d, abbadi a e . multiple query optimization by cache-aware middleware using query teamwork . in proc 在對tpc-h查詢吞吐量的測試中,minitasking能夠把系統(tǒng)的最終性能提高20%。
For example, on the database you are using, it might be possible to send multiple queries to the database server in a single call 例如,根據(jù)你用的數(shù)據(jù)庫,很可能允許在一次調(diào)用中發(fā)送多個查詢請求。

You will typically use these if you want to check the exact contents of a table after running a test rather than running multiple queries 如果需要在運(yùn)行一次測試而不是多次查詢后檢查表的確切內(nèi)容,一般會用它們。
