I must admit that I rarely use the Oracle SQL Developer because I’m using SQL*Plus, Toad from Quest and PL/SQL Developer from Allround Automations as primary tools for database administration and PL/SQL programming. They’re already providing all functionalities I need. I have nothing against Oracle SQL Developer. Actually it is quite opposite. I really want to try it, but I always find lame excuses not to. One of the excuses is that I thought this is just another new tool doing the same things other tools already could do. We’ll find out at the end of this post that I was wrong. Please read on.
Few weeks ago, I’ve received a non-compensated book review offer from Packt Publishing on Oracle SQL developer 2.1 by Sue Harper, who is currently product manager for Oracle SQL Developer. I’m really excited about this opportunity to explore this tool by reading through this book. No more procrastination! I’m approaching this book as an eager learner who would like to know more the tool and plan for a long-term use.
Let’s get started.
This book is very well organized introducing Oracle SQL Developer from installation to having sufficient information to use the tool right away after only few chapters. Personally I feel you can skip them if you’ve been using other database tools before. The tool is intuitive enough. Having said that if you’re a novice to Oracle database concept, the first four chapters are excellent resources for you to get acquainted with some basic concepts.
Chapter 1 – Getting Started with SQL Developer
The first chapter focuses mainly on the installation, initial configuration, migration from previous version and updates. Interesting information is with the XML configuration files. The chapter continues with showing how to connect and make queries to database. It ends with walking you through the navigation of the tool.
Chapter 2 – Browsing and Editing Database Objects and Data
This chapter extends from the first showing how to browse database objects. Many tips on data display, e.g., data highlighting or filtering are interesting. It goes on explaining some of Oracle database features such as Flashback and Recycle Bin which may be helpful for non-DBAs. The chapter ends with demonstrating how to create different types of database objects.
Chapter 3 – Working with the SQL Worksheet
This chapter goes in detail with tool’s main interface, SQL Worksheet. It starts with comparing Worksheet capabilities with more commonly-known SQL tools such as SQL*Plus. I think it is a good idea to show many command-line folks including myself to see that this tool is capable of doing the same things and even more. It guides you through other nifty features such as drag-and-drop query builder, formatting code, code completion, etc., though they are available in other tools as well. One of interesting features is the Code Snippets which are commonly-used codes that can be quickly added.
Chapter 4 – The Power of SQL Reports
Most of the canned/shipped reports may initially look not that useful. But if you look at them closely, some categories/reports are very interesting because they provide very useful information without writing custom queries thus saving your time. Samples are as follow:
- Table with Unindexes Foreign Keys (under Quality Assurance)
- Search Source Code (under Data Dictionary Reports > PLSQL)
- ASH and AWR Reports (under Data Dictionary Reports)
- Grants and Privileges (under Data Dictionary Reports > Security)
The user-defined report section is very helpful as well if you plan to write your own custom reports.
Chapters 5 until 8 are intended for developers because they talk about working with database objects or features for development process.
Chapter 5 – Working with PL/SQL
This section explains how to work with PL/SQL code. It includes working with triggers, functions, procedures and packages. It might not be appealing for those who have been working with other tools before. But the book explains this topic very well for those you’ve not experienced working with them before. The feature like Refractoring Code, which is to restructure code for performance improvement without impacting its original behavior, is very cool. The chapter ends with explaining how to use the tool for code debugging.
Chapter 6 – SQL and PL/SQL Tuning Tools
This chapter talks about the ability of the tool to use with the standard database tuning tools such as use of EXPLAIN PLAN, Auto Trace and other canned report for Top SQLs. The book also highlights new 11g’s PL/SQL Hierarchical Profiler feature which records not only the time spent in each sub program, but also number of calls to the subprogram.
Chapter 7 – Managing Files
This is one of strengths of Oracle SQL Developer over others because it integrates with open source version control system. I’m really glad that author covers this topic in detail. The version control integration is very nice to have if your organization does not have a dedicated source control system. This chapter will show you how to check in/out your code and work in team development with code comparison and merging.
Chapter 8 – Importing, Exporting and Working with Data
This chapter may be beneficial to many developers who need to perform data movement. SQL Developer can perform data export and import in various formats including CSV, Fixed, HTML, DML statements, and SQL Loader. Using wizard such as database copy allows to move data without using database utilities like imp/exp or data pump.
The remaining sections are considered to be topic-specific. This means that you can choose to read only what interests you.
Chapter 9 – Database Connections and JDBC Drivers
Great section hightlights the advantages of this tool because Oracle SQL Developer can also connect to non-Oracle databases including MySQL, Sybase, DB2, Teradata, Microsoft Access via 3rd-party JDBC drivers. This is tremendously beneficial when there is a need to migrate data from the 3rd-party database to Oracle.
Chapter 10 – Introducing SQL Developer Data Modeler
Even though Oracle SQL Developer Data Modeler is a priced independent product (SQL Developer has a SQL Data Model Viewer extension), this book showcases Data Modeler tool by going into detail of its features including connecting to database, importing dictionary, working with model, creating ERD, and so on. The chapter ends with showing the integration of the Data Modeler within SQL Developer.
(More information about Oracle SQL Developer Data Modeler can be found on its site.)
Chapter 11 – Extending SQL Developer
Personally I think this feature sets this tool apart from others. With capability of supporting XML and Java extensions, you can create custom features to plug-in to the tool and share them with others. This chapter shows some good samples of using XML extensions in the tool.
Chapter 12 – Working with Application Express
As an APEX developer, the integration with APEX in Oracle SQL developer is a hidden gem. Now all APEX objects can be easily viewed at our finger tips. There is no need to jump into many pages back and forth. This book explains clearly on how to use SQL Developer to work with APEX objects including LOVs, Pages, Items, etc. Tuning application’s SQL and PL/SQL codes which are visible through the tool becomes much easier. One of the nice features is an ease of refracting PL/SQL code (e.g., from anonymous block) to a compiled procedure which is much more efficient. The chapter ends with showing us how to manage applications including importing and exporting applications.
Chapter 13 – Working with SQL Developer Migration
This chapter extends its feature of this tool connecting to non-Oracle database for data migration purpose. The Oracle SQL Developer Migration is an integrated feature of Oracle SQL Developer. The book shows technical aspect of using the tool for data migration. This includes migration repository preparation and database connection.
After reading through this book and following most of samples, I’m impressed with varieties of unique features (such as integration with APEX, version control, Data Modeler, etc.) this tool offers. As a matter of fact, I’m already using it in our current APEX development project, and plan to extend its usage more in other areas. The flow and layout of this book really helps me understand and appreciate SQL Developer tool. The book covers some basic concepts filling up the gap for those who are new to accessing Oracle database. But in general, I agree with author that those who are already familiar with Oracle database concepts will get more out of this book.
Thanks to Packt Publishing for book review offer.
