Posted by: junyuo Posted on: 2004-01-13 08:49 1Z0-007考试心得 推荐的书籍:OCA/OCP: Introduction to Oracle9i SQL Study Guide[http://www.amazon.com/exec/obidos/tg/detail/-/0782140629/102-2875927-0020104?v=glance] 书籍勘误:http://scooter.sybex.com/erratatracking.nsf/weberrataform?OpenForm&ISBN=4062 这个考试的范畴包括: →Writing Basic SQL Select Statements →Restricting and Sorting Data →Single-Row Functions →Displaying Data from Multiple Tables →Aggregating Data using Group Functions →Subqueries →Producing Readable Output with iSQL*Plus →Manipulating Data →Creating and Managing Tables →Including Constraints →Creating Views →Creating Other Database Objects →Controlling User Access 对于具有信息相关背景的人来说,这个考试应该不会太困难,一来是念书的时候都有上过DBMS的课程了,二来是平常就有在使用了,所以在大部分的主题如"Writing Basic SQL Select Statements", "Restricting and Sorting Data", "Aggregating Data using Group Functions", "Displaying Data from Multiple Tables ", "Subqueries"等等,都应该有某种程度的掌握度。 反倒是需注意几个地方,如"Single-Row Functions",Oracle提供许多自己独有的function给我们使用,如DECODE, NVL, NVL2、CASE...WHEN...THEN...END等等,都是出现率相当高的题目;在DML方面,Merge的用法;在Join方面,Outer Join的用法,Join...Using clause、Join...On clause以及natual join也出现了好几题;还有比较少用到的部份如"Producing Readable Output with iSQL*Plus"需要多看几遍,其它的部分如"Controlling User Access", grant privilege的地方也要多看一下。 与书本附的mock来比较,其实真正考试的题目反倒是比较简单一些。所以只要做做书本所附的mock(大概有400题左右),应该就足够上战场了。如果不放心的话,也可以去网络上找找看,不过可以查到的信息很少就是了。 其它可以参考的link: 1.
