How to Select All Table Names in Oracle

Trying to select all Oracle table names? You’re in luck! This article will help you with a step-by-step guide. Let’s dive in!

Why select all table names in Oracle? It gives you access to the database structure and organization for efficient management. What’s the best way? Use SQL queries from Oracle’s data dictionary views. They contain metadata about the tables and database components.

Here’s an example query:

SELECT table_name FROM all_tables;

Execute it to get a list of all table names in the Oracle database. To filter the results, modify the query.

Did you know Oracle Corporation is a leading enterprise software solutions provider? They deliver cutting-edge technology that meets modern businesses’ demands.

Explaining the importance of selecting all table names in Oracle

Gaining an overview of Oracle’s database structure via a comprehensive list of table names is essential for DBAs and developers. This helps with data analysis, troubleshooting, and optimizing query performance. Knowing the table names simplifies the process of locating specific information, saving time and providing seamless collaboration between team members.

Selecting the table names also ensures data integrity and security, allowing administrators to implement access controls and protect sensitive information. This strengthens the system’s robustness and reliability.

One can use SQL queries like “SELECT TABLE_NAME FROM ALL_TABLES” to extract the table names. This command retrieves details such as table names, owners, creation dates, and row counts. This contributes to better resource allocation, informed decision-making, and efficient database management.

Step 1: Logging into Oracle database

  1. Open the Oracle SQL Developer tool.
  2. Input your username and password in the designated fields.
  3. Click “Connect” – this will create a connection with the database.
  4. You can now see various tabs and options like the “Connections” tab and the SQL Worksheet.
  5. Start executing queries or accessing specific tables in the Oracle database.

Be sure to provide accurate info for a successful connection – and make sure you’ve got authorization to access the intended data.

Don’t miss out on the power of Oracle! Logging in allows for efficient data management, analysis, and manipulation. Unlock the potential of Oracle software now!

Step 2: Using the SHOW TABLES command to list all tables

The SHOW TABLES command is an amazing tool for Oracle users! It enables fast and easy access to a comprehensive list of database tables. Here’s a simple guide on how to use it:

  1. Launch Oracle software.
  2. Open the command prompt or terminal window.
  3. Type “SHOW TABLES;” and press Enter.
  4. Wait for the software to process the command.
  5. The software will display a list of all table names in your Oracle database.
  6. Note down these table names for later reference or analysis.

Remember, using the SHOW TABLES command may require certain privileges and access rights, depending on your role in the Oracle system. If you have any issues, don’t hesitate to ask your database administrator for help.

Step 3: Querying the data dictionary to retrieve all table names

Querying the data dictionary is critical to get all Oracle table names. Execute specific queries to access the info stored in the dictionary and have the details of each table in the database.

  1. Connect to the Oracle database: Use a client tool or command-line interface to establish a connection with the Oracle database. This allows you to have the privileges to query the data dictionary.
  2. Access the data dictionary: Execute a query against the “SYS.ALL_TABLES” view. It has info of all tables accessible to the current user.
  3. Retrieve the table names: Use SQL statements to get the info from the “SYS.ALL_TABLES” view. Select only the “TABLE_NAME” column from this view.
  4. Display/process the results: After retrieving all table names, display or process them according to your needs. Save into a file, use as input for another script, or analyze further.

Also, there are other useful views available for getting different types of tables in a Oracle database. Like “USER_TABLES,” which shows info of tables owned by the current user, and “DBA_TABLES,” which has details of tables across all users.

Now think of a company going through a major system upgrade. The IT team needed a reliable list of all table names for a successful and efficient data migration. So, they followed the above steps to quickly get all the table names from the Oracle data dictionary. This enabled them to plan their migration strategy accurately and proceed with confidence.

Step 4: Using the SELECT statement to fetch table names from the data dictionary

Using a SELECT statement in Oracle makes getting table names from the data dictionary effortless. Here’s how:

  1. Connect to your Oracle software and log in with the correct credentials.
  2. Open the SQL editor, and type this query: “SELECT table_name FROM all_tables;“. This will fetch all the table names in the data dictionary.
  3. Click the Run button or press Ctrl+Enter. You’ll then see a list of table names on your screen – these names represent all the tables in your Oracle database.

This method with the SELECT statement makes it easier to get table names from the data dictionary in Oracle. Adjust the code for any filtering or sorting needs.

It’s amazing to think of how much technology has changed. In the past, getting table names in a database was a tedious manual process that took a lot of time. But now, with Oracle’s database management system, developers have convenient ways to access that info quickly.

Oracle’s SELECT statement proves its user-friendly nature. It enables users to do their tasks quickly, leaving more time for analysis and decision making.

So if you ever need to get table names from your Oracle database, remember this simple method with the SELECT statement. It’s a reminder of how far we’ve come with technology!

Step 5: Storing the table names in a separate table or file for future reference

Storing table names apart is a must for efficient Oracle software. Here’s a 5-step guide for doing that:

  1. Generate a new table/file: Use SQL commands or database management tools to create a table/file for storage.
  2. Structure definition: List columns like table name, owner, creation date, etc. Make sure the data types are correct.
  3. Get the names: Use SQL queries to fetch the names, like ALL_TABLES or USER_TABLES. Insert the names into the created table.
  4. Automation: Create scripts/stored procedures to update the table names regularly.
  5. Ensure data integrity: Update the separate table/file if any changes are made to tables (e.g. renaming/dropping).

Backup the stored info to protect data. Storing table names offers multiple benefits: Easy navigation, documentation, and data relationships understanding. Follow these steps to store & manage names in Oracle DB for future reference.

A multinational telecoms firm was having a hard time managing thousands of table names within a complex database. To make them easily accessible, they created a single table to store details about each table. This made it easier to access them and also generate reports about data usage.

The company invested in this practice and saw great results. Their data management processes improved, and they could make informed decisions due to accurate information. Storing table names separately made a huge difference to their efficiency & productivity.


It’s clear that Oracle users can easily select all table names. By following the steps above, they can get the data from the software.

It’s important to understand Oracle, so users can manage data and increase workflow.

In addition, users should explore further Oracle features. They can unlock greater potential and efficiency by delving into the many features of this software.

Oracle is essential for staying competitive. Users should hone their skills and increase their knowledge of this software to become a valuable asset in their industry. Don’t miss out on the opportunities Oracle provides.
