MFC Black Book Introduction: Are you an MFC programmer? Good. There are two types of MFC programmers. What kind are you? The first kind are the good programmers who write programs that conform to the way MFC wants you to do things. The second bunch are wild-eyed anarchists who insist on getting things done their way. Me, I’m in the second group. If you are in the same boat (or would like to be) this book is for you. This book won’t teach you MFC—not in the traditional sense. You should pick it up with a good understanding of basic MFC programming and a desire to do things differently. This isn’t a Scribble tutorial (although I will review some fundamentals in the first chapter). You will learn how to wring every Drop from your MFC programs. You’ll discover how to use, abuse, and abandon the document/view architecture. If you’ve ever wanted custom archives, you’ll find that, too.

SQL是英文Structured Query Language的縮寫，意思為結(jié)構(gòu)化查詢語言。SQL語言的主要功能就是同各種數(shù)據(jù)庫建立聯(lián)系，進行溝通。按照ANSI(美國國家標準協(xié)會)的規(guī)定， SQL被作為關(guān)系型數(shù)據(jù)庫管理系統(tǒng)的標準語言。SQL語句可以用來執(zhí)行各種各樣的操作，例如更新數(shù)據(jù)庫中的數(shù)據(jù)，從數(shù)據(jù)庫中提取數(shù)據(jù)等。目前，絕大多數(shù)流 行的關(guān)系型數(shù)據(jù)庫管理系統(tǒng)，如Oracle, Sybase, Microsoft SQL Server, Access等都采用了SQL語言標準。雖然很多數(shù)據(jù)庫都對SQL語句進行了再開發(fā)和擴展，但是包括Select, Insert, Update, Delete, Create, 以及Drop在內(nèi)的標準的SQL命令仍然可以被用來完成幾乎所有的數(shù)據(jù)庫操作。下面，我們就來詳細介紹一下SQL語言的基本知識。
