课程名称：1Z0-149: Oracle数据库PL/SQL开发人员专业认证2024 课程概述： 本课程旨在为准备参加1Z0-149考试的学员提供全面的PL/SQL编程知识，帮助他们获得Oracle数据库PL/SQL开发人员认证专业资格。此认证专为验证在Oracle数据库10g、11g及12c中开发数据库中心互联网应用程序的专业知识而设计。课程内容将深入探讨各个考试主题，使考生有效备考。 考试主题包括： 1. 声明PL/SQL变量：理解标识符、变量使用和数据类型，包括%TYPE和%ROWTYPE属性。 2. 编写可执行语句：识别词法单元，使用SQL函数和序列，管理类型转换，编写可读代码。 3. 在PL/SQL中编写SQL：创建包含DML和事务控制的可执行块，利用INTO子句处理结果。 4. 编写控制结构：使用IF、CASE语句构建循环，通过EXIT和CONTINUE语句管理控制流程。 5. 处理复合数据类型：创建和初始化用户定义的记录，理解记录、集合和INDEX BY表之间的区别。 6. 使用显式游标：区分隐式和显式游标，控制游标，提取数据，处理参数，并管理行锁定。 7. 处理异常：定义和处理PL/SQL异常，识别未处理异常并有效传播。 8. 使用PL/SQL子程序：区分块和子程序，创建和调用过程，理解其优势。 9. 创建过程和函数：创建和管理过程与函数，处理参数和异常。 10. 创建包：理解包的优点与组成，处理包规格和主体，重载子程序并使用前向声明。 11. 使用包：利用包类型、变量、常量和函数，并限制对包子程序的访问。 12. 使用动态SQL：描述SQL语句执行流程，使用本地动态SQL（NDS），并在SQL语句中绑定PL/SQL类型。 13. PL/SQL代码设计考虑：创建常量、异常和本地子程序，控制权限并优化代码性能。 14. 创建触发器：在DDL语句和系统事件上创建触发器，理解其类型及用途。 15. 使用PL/SQL编译器：描述编译器特性，使用初始化参数，并处理编译时警告。 16. 管理PL/SQL代码：使用条件编译、授予角色、控制代码访问并管理弃用代码。 17. 管理依赖关系：有效跟踪和管理过程依赖关系。 通过本课程的学习，您将掌握通过1Z0-149认证所需的所有知识和技能，为成为一名合格的Oracle数据库PL/SQL开发人员做好充分准备。
Prepare to pass exam: 1Z0-149 Become an Oracle Database PL/SQL Developer Certified ProfessionalPreparing for the Oracle Advanced PL/SQL Developer Certified Professional exam (1Z0-149) requires a comprehensive understanding of various topics related to PL/SQL programming. This certification is designed to validate expertise in developing database-centric Internet applications for Oracle Database 10g, 11g, and 12c. In this guide, we'll delve into each exam topic to help you prepare effectively.Exam Topics:Declaring PL/SQL Variables: Understand identifiers, variable usage, and data types including %TYPE and %ROWTYPE attributes.Writing Executable Statements: Identify lexical units, use SQL functions and sequences, manage conversions, and write readable code.Writing SQL in PL/SQL: Create executable blocks with DML and transaction control, utilize INTO clause for result handling.Writing Control Structures: Use IF, CASE statements, construct loops, and manage control flow with EXIT and CONTINUE statements.Working with Composite Data Types: Create and initialize user-defined records, understand differences among records, collections, and INDEX BY tables.Using Explicit Cursors: Differentiate implicit and explicit cursors, control cursors, fetch data, handle parameters, and manage row locking.Handling Exceptions: Define and handle PL/SQL exceptions, recognize unhandled exceptions, and propagate them effectively.Using PL/SQL Subprograms: Differentiate blocks and subprograms, create and invoke procedures, and understand their benefits.Creating Procedures and Functions: Create and manage procedures and functions, work with parameters and exceptions.Creating Packages: Understand package benefits and components, work with package specification and body, overload subprograms, and use forward declarations.Working with Packages: Utilize package types, variables, constants, and functions, and restrict access to package subprograms.Using Dynamic SQL: Describe SQL statement execution flow, use Native Dynamic SQL (NDS), and bind PL/SQL types in SQL statements.Design Considerations for PL/SQL Code: Create constants, exceptions, and local subprograms, control privileges, and optimize code performance.Creating Triggers: Create triggers on DDL statements and system events, and understand their types and uses.Using the PL/SQL Compiler: Describe compiler features, use initialization parameters, and handle compile-time warnings.Managing PL/SQL Code: Use conditional compilation, grant roles, control code access, and manage deprecated code.Managing Dependencies: Track and manage procedural dependencies effectively.
