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 system view to query the metadata information of the database. The most commonly used is the "DBA_TABLES" view, which contains all table information in the database; 2. , use the DESC command, the command is "DESC table name"; 3. Use the USER_TABLES view, a simplified version of the "DBA_TABLES" view, which contains table information owned by the current user, etc.

The operating environment of this tutorial: Windows 10 system, Oracle version 19c, DELL G3 computer.

Oracle is a relational database management system that can be used to store and manage large-scale data. In Oracle, tables are managed by tablespaces. Table space is a logical concept, which is used to allocate and manage physical storage space.

To check which table space a table belongs to, you can use the following methods:

1. Use the system view: Oracle provides some system views for querying database metadata information. These views can be queried to see the tablespace to which the table belongs. The most commonly used one is the DBA_TABLES view, which contains all table information in the database. You can query the table space to which the table belongs through the following SQL statement:

SELECT table_name, tablespace_name
FROM dba_tables
WHERE table_name = '表名';

Replace the 'table name' in the above SQL statement with the actual table name to be queried.

2. Use DESC command: In Oracle, you can use the DESC command to view the structure information of a table. In the query results, the table space to which the table belongs is displayed. You can use the DESC command to view the table space to which the table belongs through the following SQL statement:

DESC 表名;

Replace the 'table name' in the above SQL statement with the actual table name to be queried.

3. Use the USER_TABLES view: The USER_TABLES view is a simplified version of the DBA_TABLES view. It only contains table information owned by the current user (that is, the currently logged in user). You can query the table space to which the table owned by the current user belongs through the following SQL statement:

SELECT table_name, tablespace_name
FROM user_tables
WHERE table_name = 'table name';

Replace the 'table name' in the above SQL statement with the actual table name to be queried.

The above are three commonly used methods to view the table space to which a table belongs. By querying the system view, using the DESC command, or querying the USER_TABLES view, you can easily obtain the table space information to which the table belongs.
