How to determine the tablespace of a table in Oracle Database

Determining the table space of a table in an Oracle database is an important operation in database management. Through this operation, the database space can be better managed and database performance can be optimized. In Oracle database, each table will be allocated to a table space. A table space is a logical object used to store table and index data. Determining the table space of a table mainly involves querying the system tables of the database. The following is a specific code example to implement this function:

1. First, log in to the Oracle database as a system administrator or a user with query permissions .
2. Then open the SQL command line or SQL development tool and enter the following SQL statement to query the table space of the specified table:

SELECT table_name, tablespace_name 
FROM user_tables 
WHERE table_name = 'YOUR_TABLE_NAME';

In this SQL statement, YOUR_TABLE_NAME is the name of the table to be queried. Through this statement, you can query the name of the table space where the specified table is located.

3. If you want to query the table space where all tables are located, you can use the following SQL statement:

SELECT table_name, tablespace_name 
FROM user_tables;

This SQL statement will list the table names of all tables and the locations where they are located. Table space name.

4. You can execute these queries in Oracle SQL Developer by following these steps:

   • Open Oracle SQL Developer and connect to the database
   • In Enter the above SQL statement in SQL Worksheet
   • Click the execute button to execute the SQL statement
   • The query results will be displayed in the result window, and you can view the table space information of the table

By executing the above code example, you can easily determine the table space of the specified table in the Oracle database, and you can also understand the table space where all tables are located, so as to better manage the database space.
