segment is session specific, not table specific D is wrong because it is the session server process that writes the data, not the user process 16 D and E Aggregations and joins make a view complex and make DML impossible A, B, and C Selection and projection or renaming columns does not make the view complex PART II 17 D Sad but true Views will not help performance, unless they include tuning hints A, B, and C A is wrong because a view is only a SELECT statement; it doesn t prerun the query B is wrong because the Oracle optimizer will sort out any differences in syntax C is wrong because, although views are precompiled, this doesn t affect the speed of compiling a user s statement 18 C The WITH CHECK OPTION will prevent DML that would cause a row to disappear from the view A, B, and D A is wrong because views are by default created read/write B is wrong because the view is a simple view D is wrong because the statement cannot succeed because the check option will reject it 19 A There is a NOT NULL or PRIMARY KEY constraint on DEPTDEPTNO B, C, and D B is wrong because constraints are enforced on detail tables, not on views C and D are wrong because the error message would be different 20 B and D Public synonyms are not schema objects and so can only be addressed directly They can have the same names as schema objects A and C These are wrong because users must be granted privileges on a public synonym before they can see it or select from it 21 B The order of priority is to search the schema namespace before the public namespace, so it will be the private synonym (to EMPLOYEES) that will be found A, C, and D A is wrong because a synonym can exist in both the public namespace and the schema namespace C is wrong because the order of priority will find the private synonym first D is wrong because it would not be possible to have a table and a private synonym in the same schema with the same name 22 D The synonym will be fine, but the view will be invalid Oracle will attempt to recompile the view, but this will fail A, B, C, and E A is wrong because the view will be invalid B is wrong because the FORCE keyword can only be applied when creating a view (and it would still be invalid, even so) C is wrong because the synonym will be fine E is wrong because views are not dropped implicitly (unlike indexes and constraints).

23 D The default is NOCYCLE, and the sequence cannot advance further A, B, and C A and B are wrong because CYCLE is disabled by default If it were enabled, the next number issued would be 1 (not zero) because 1 is the default for START WITH C is wrong because under no circumstances will a sequence issue repeating values 24 A It is not possible to change the next value of a sequence, so you must re-create it B, C, and D B is wrong because, while a NOCYCLE sequence can never reissue numbers, there is no reason why a new sequence (with the same name) cannot do so C is wrong because START WITH can only be specified at creation time D is wrong because this will not force an instant cycle, it will only affect what happens when the sequence reaches its MAXVALUE or MINVALUE

In addition to the tips in this chapter, there are several tips in 1 that will prove useful to print designers as well as web designers

In this chapter you will learn to 05191 Describe Each Data Manipulation Language (DML) Statement 05192 Insert Rows into a Table 05193 Update Rows in a Table 05194 Delete Rows from a Table 05195 Control Transactions 05291 Manage Data Using DML 05292 Identify and Administer PL/SQL Objects 05293 Monitor and Resolve Locking Conflicts 052101 Explain the Purpose of Undo 052102 Understand How Transactions Generate Undo 052103 Manage Undo

Data in a relational database is managed with the DML (Data Manipulation Language) commands of SQL These are INSERT, UPDATE, DELETE, and (with more recent versions of SQL) MERGE This chapter discusses what happens in memory, and on disk, when you execute INSERT, UPDATE, or DELETE statements the manner in which changed data is written to blocks of table and index segments and the old version of the data is written out to blocks of an undo segment The theory behind this, summarized as the ACID test, which every relational database must pass, is explored, and you will see the practicalities of how undo data is managed The transaction control statements COMMIT and ROLLBACK, which are closely associated with DML commands, are explained along with a discussion of some basic PL/SQL objects The chapter ends with a detailed examination of concurrent data access and table and row locking

When working in Photoshop, you will be either opening an existing file or creating a new one If you are opening a file, it will already be in a specified color mode; most likely it will open in RGB (red,

Strictly speaking, there are five DML commands: SELECT INSERT UPDATE DELETE MERGE In practice, most database professionals never include SELECT as part of DML It is considered to be a separate language in its own right, which is not unreasonable when you consider that the next five chapters are dedicated to describing it The MERGE command is often dropped as well, not because it isn t clearly a data manipulation command but because it doesn t do anything that cannot be done with other commands MERGE can be thought of as a shortcut for executing either an INSERT or an UPDATE or a DELETE, depending on some condition A command often considered with DML is TRUNCATE This is actually a DDL (Data Definition Language) command, but as the effect for end users is the same as for a DELETE (though its implementation is totally different), it does fit with DML

Oracle stores data in the form of rows in tables Tables are populated with rows (just as a country is populated with people) in several ways, but the most common method is with the INSERT statement SQL is a set-oriented language, so any one command can affect one row or a set of rows It follows that one INSERT statement can insert an individual row into one table or many rows into many tables The basic versions of the statement do insert just one row, but more complex variations can, with one command, insert multiple rows into multiple tables
