After you have created a new tablespace, you can give it to your users for them to create tables in the new tablespace. To create a table in a specific tablespace, you need to use the TABLESPACE clause in the CREATE TABLE statement. Here is a sample script:

SQL> connect SYSTEM/globalguideline

Connected.

SQL> CREATE TABLESPACE my_space

2 DATAFILE '/temp/my_space.dbf' SIZE 10M;

Tablespace created.

SQL> connect HR/globalguideline

Connected.

SQL> CREATE TABLE my_team TABLESPACE my_space

2 AS SELECT * FROM employees;

Table created.

SQL> SELECT table_name, tablespace_name, num_rows

2 FROM USER_TABLES

3 WHERE tablespace_name in ('USERS', 'MY_SPACE');

TABLE_NAME    TABLESPACE_NAME NUM_ROWS

------------------------------ ---------------- ----------

MY_TEAM    MY_SPACE   - 

EMPLOYEES    USERS   107
