To view all tables in Oracle, you can use the "SELECT table_name FROM user_tables;" query to get a list of table names owned by the current user. Additionally, you can use the "all_tables" view to view all tables for all users and use the "desc table_name;" command to view details for a specific table.
How to view all tables in Oracle
To view all tables in an Oracle database, you can use the following query:
<code class="sql">SELECT table_name FROM user_tables;</code>
This query returns a list of names for all tables owned by your current user.
Expand the answer:
- user_tables : This is an Oracle system view that contains metadata information about tables in the database.
- table_name : This is a column in the user_tables view that contains the table name.
Example:
To view all tables owned by a user named "user_db", you can use the following query:
<code class="sql">SELECT table_name FROM user_tables WHERE owner = 'user_db';</code>
Notice:
- If you want to view all tables for all users, you need to use the "all_tables" view instead of the "user_tables" view.
- You can also use the "desc" command to view detailed information about a specific table, for example:
<code class="sql">DESC table_name;</code>

The development history of Oracle software from database to cloud computing includes: 1. Originated in 1977, it initially focused on relational database management system (RDBMS), and quickly became the first choice for enterprise-level applications; 2. Expand to middleware, development tools and ERP systems to form a complete set of enterprise solutions; 3. Oracle database supports SQL, providing high performance and scalability, suitable for small to large enterprise systems; 4. The rise of cloud computing services further expands Oracle's product line to meet all aspects of enterprise IT needs.

MySQL and Oracle selection should be based on cost, performance, complexity and functional requirements: 1. MySQL is suitable for projects with limited budgets, is simple to install, and is suitable for small to medium-sized applications. 2. Oracle is suitable for large enterprises and performs excellently in handling large-scale data and high concurrent requests, but is costly and complex in configuration.

Oracle helps businesses achieve digital transformation and data management through its products and services. 1) Oracle provides a comprehensive product portfolio, including database management systems, ERP and CRM systems, helping enterprises automate and optimize business processes. 2) Oracle's ERP systems such as E-BusinessSuite and FusionApplications realize end-to-end business process automation, improve efficiency and reduce costs, but have high implementation and maintenance costs. 3) OracleDatabase provides high concurrency and high availability data processing, but has high licensing costs. 4) Performance optimization and best practices include the rational use of indexing and partitioning technology, regular database maintenance and compliance with coding specifications.

Steps to delete the failed database after Oracle failed to build a library: Use sys username to connect to the target instance. Use DROP DATABASE to delete the database. Query v$database to confirm that the database has been deleted.

In Oracle, the FOR LOOP loop can create cursors dynamically. The steps are: 1. Define the cursor type; 2. Create the loop; 3. Create the cursor dynamically; 4. Execute the cursor; 5. Close the cursor. Example: A cursor can be created cycle-by-circuit to display the names and salaries of the top 10 employees.

Oracle views can be exported through the EXP utility: Log in to the Oracle database. Start the EXP utility, specifying the view name and export directory. Enter export parameters, including target mode, file format, and tablespace. Start exporting. Verify the export using the impdp utility.

To stop an Oracle database, perform the following steps: 1. Connect to the database; 2. Shutdown immediately; 3. Shutdown abort completely.
