What are the oracle database operation tools?

In addition to SQL*Plus, there are tools for operating Oracle databases: SQL Developer: free tools, interface friendly, and support graphical operations and debugging. Toad: Business tools, feature-rich, excellent in database management and tuning. PL/SQL Developer: Powerful tools for PL/SQL development, code editing and debugging. Dbeaver: Free open source tool, supports multiple databases, and has a simple interface.

Oracle Database Operation Tools: Not just SQL*Plus

When many friends mention operating Oracle databases, SQL Plus immediately pops up in their minds. That's right, it is getting stronger and stronger, and it is still the favorite of many old programmers. But the times are progressing and tools are also evolving. It is already a bit "out" to rely solely on SQL Plus. In this article, let’s talk about the tools that allow you to operate Oracle databases more efficiently and more elegantly, and their respective advantages and disadvantages. After reading, you will be able to choose tools that suit your project more wisely to avoid pitfalls.

Review of basic knowledge: first consolidate SQL

To play with Oracle databases, SQL is a hurdle that cannot be avoided. You must be proficient in basic operations such as DDL (data definition language), DML (data manipulation language), and DCL (data control language). Don’t talk about it on paper, practice more, write sentences about adding, deleting, modifying and checking, and experience the temper of the database. Remember, whether SQL is well written directly affects your efficiency in operating the database. Don't underestimate those simple SQL statements. Good optimization can help you save a lot of time and resources. For example, the use of indexes and clever connection queries are the keys to improving SQL performance.

Core concept: The tools for efficient operation

Let’s first talk about some options outside of SQL*Plus.

• SQL Developer: This is a free tool provided by Oracle. It has powerful functions and a friendly interface, which is much more comfortable than SQL*Plus. It supports graphical interface operation, automatic code completion, and debugging functions are relatively complete. For beginners, it is easier to get started. But it may perform slightly worse than some professional tools when dealing with super-large data sets.
• Toad: This is a commercial tool with a lot of features, especially in database management and performance tuning. It provides powerful SQL editors, database browsers, report generators, and more. If you need to perform complex database management tasks, Toad is a good choice. However, it's relatively expensive.
• PL/SQL Developer: A tool specially developed for PL/SQL. If you need to develop stored procedures, functions, triggers and other PL/SQL code, this tool will give you twice the result with half the effort. Its code editing and debugging functions are very powerful, which can effectively improve development efficiency. Likewise, it is also a business tool.
• Dbeaver: This is an open source database management tool that supports a variety of databases, including Oracle. It has comprehensive features, simple interface, and is free. If you have a limited budget and need a powerful tool, Dbeaver is a great choice. However, some of its features may not be as perfect as commercial tools.

Example of usage: Taking SQL Developer as an example

Suppose we want to query the data in a table. In SQL Developer, you can directly enter SQL statements in SQL Worksheet and then click the Run button. It will automatically format SQL statements and display the query results. More advanced usages, such as using its graphical interface to create tables, views, indexes, etc., are much more convenient than pure SQL statements. In large-scale projects, this can greatly improve development efficiency and reduce the chance of errors.

Common errors and debugging skills: Only by learning to troubleshoot mistakes can you become a master

During database operations, errors are inevitable. Common errors include SQL syntax errors, permission issues, connection issues, etc. Learn to use debugging functions provided by tools, such as breakpoint debugging of SQL Developer, which can effectively improve your troubleshooting efficiency. Only by carefully reading the error message and combining it with the database log can the root cause of the problem be found.

Performance Optimization and Best Practices: Write efficient SQL to avoid performance bottlenecks

Writing efficient SQL statements is crucial. Avoid using full table scanning and try to use indexes; optimize connection queries and choose the appropriate connection method; use appropriate paging queries to avoid querying too much data at one time. These are the keys to improving database performance. In addition, developing good programming habits, such as writing clear and easy-to-understand code and adding necessary comments, can also improve the maintainability of the code.

Finally, choosing the right tool is only the first step. What is more important is to master the skills and methods of database operation to truly improve your work efficiency. Remember, practice brings true knowledge, do more and think more, and you can become a real database master.
