I have created tablespace named CUSTOMER using EM Express, but when I have tried to create table in that tablespace I am receiving tablespace CUSTOMER does not exist. In Oracle 12c tablespace is a logical storage container that houses physical data files in which database tables and indexes are stored.

When you create a new tablespace, it is in the read-write mode. In a database, tablespaces are created in two ways: By default for internal database structures By the database administrator (DBA) to store user objects For example, […] --（例）表領域(user01)をファイル名「user01.dbf」、100mbのサイズで作成する create tablespace user01 datafile 'd:\oracle\data\user01.dbf' size 100m segment space management auto ; Yep, Oracle has temporary tables. The issue I am having is apparently it created the table using a different tablespace than the one we are supposed to use. CREATE TABLE suppliers ( supplier_id number(10) NOT NULL, supplier_name varchar2(50) NOT NULL, address varchar2(50), city varchar2(50), state varchar2(25), zip_code varchar2(10) ); However, it does not allow you to create or alter objects in a read-only tablespace. I want to create some tables in our database from some queries I have developed. The following is a CREATE TABLESPACE statement that creates an undo tablespace: CREATE UNDO TABLESPACE tbs_undo_01 DATAFILE 'tbs_undo_01.f' SIZE 5M AUTOEXTEND ON RETENTION GUARANTEE; This CREATE TABLESPACE statement creates an undo tablespace called tbs_undo_01 that is 5MB in size and has one data file called tbs_undo_01.f.

The meanings of the parameters in the script can be found in the following table.

Next, create a new table t1 whose tablespace is tbs10: CREATE TABLE t1(id INT PRIMARY KEY) TABLESPACE tbs10; Then, insert 1,000,000 rows into the t1 table: BEGIN FOR counter IN 1..1000000 loop INSERT INTO t1(id) VALUES (counter); END loop; END; / Oracle issued the following error: ORA-01653: unable to extend table OT.T1 by 8 in tablespace TBS10

It is a bad practice to frequently create and drop temporary tables in Oracle. Finding out who owns a table and what tablespace it is in is a pretty common need of the DBA.

Practice Exercise #1: Create an Oracle table called suppliers that stores supplier ID, name, and address information.. However, in Oracle, only the data in a temporary table is temporary.

create table customer (id numerical, name varchar2 (30)) tablespace customer; I have tried to write CUSTOMER or customer, results would be the same. Here is a link to an AskTom article describing them and here is the official oracle CREATE TABLE documentation. Oracle allows you to remove objects such as tables and indexes from a read-only tablespace. Below you can see examples and explanations about creating a tablespace.

Table and tablespace location. By defeault, Oracle creates a single temporary tablespace named TEMP for each new Oracle Database installation. Solution for Practice Exercise #1: The Oracle CREATE TABLE statement for the suppliers table is:.
