How to check which table space a table belongs to in Oracle

Oracle method to check which table space a table belongs to: 1. Use the "SELECT" statement and specify the table name to find the table space to which the specified table belongs; 2. Use the database management tools provided by Oracle to check the table These tools usually provide a graphical interface to make the operation more intuitive and convenient; 3. In SQL*Plus, you can view the table space to which the table belongs by entering the "DESCRIBEyour_table_name;" command.

The operating environment of this tutorial: Windows 10 system, Oracle version 19c, Dell g3 computer.

Oracle is a popular relational database management system that is widely used in enterprise-level software development. In Oracle, data is stored in tables, and tables are stored in tablespaces. A tablespace is a logical storage structure used to organize and manage tables and other objects in a database.

When operating tables in Oracle, sometimes you need to check the table space to which the table belongs. This can help database administrators understand where tables are stored and make adjustments and optimizations accordingly. This article will introduce several common methods to see which table space a table belongs to.

Method 1: Use SQL query

The simplest method is to obtain the table space to which the table belongs by querying Oracle's internal data dictionary view. The following is a sample SQL query statement:

SELECTtable_name,tablespace_name
FROMuser_tables
WHEREtable_name='your_table_name';

In the above query, you can find the table space to which the specified table belongs by specifying the table name ('your_table_name'). This query uses the user_tables view, which contains all tables under the current user and the table spaces to which they belong.

Method 2: Use database management tools

In addition to using SQL queries, you can also use the database management tools provided by Oracle to view the table space to which the table belongs. These tools usually provide graphical interfaces, making operation more intuitive and convenient.

Oracle SQL Developer is a popular free tool that can be used to manage Oracle databases. By opening SQL Developer, connecting to the corresponding database, you can navigate to the specified table, right-click the table and select "Properties", which will display detailed information about the table, including the table space it belongs to.

Similarly, Oracle Enterprise Manager is also a powerful database management tool that can be used to manage and monitor Oracle databases. In Enterprise Manager, you can easily view the table space to which the table belongs, as well as other table-related information.

Method 3: Use command line tools

In addition to graphical interface tools, you can also use command line tools to view the table space to which the table belongs. In Oracle, there is a command line utility called "SQL*Plus", which is the basic tool provided by Oracle for users to interact with the database.

In SQL*Plus, you can view the table space to which the table belongs by entering the following command:

DESCRIBEyour_table_name;

This command will display the structural information of the specified table, including the name of the table space.

Summary:

The above introduces several common methods to view the table space to which the Oracle table belongs. These methods include using SQL queries, database management tools, and command line tools. Choose a method that suits you according to the actual situation to view table space information in order to better manage and optimize the database.
