To create a table in Oracle Apex, follow these steps:
Login to your Oracle Apex account and navigate to the SQL Workshop section.
Click on the SQL Commands icon to open the SQL Commands page.
In the SQL Commands page, enter the SQL command to create a new table. For example, the following command will create a new table called "employees":
CREATE TABLE employees (
employee_id NUMBER,
first_name VARCHAR2(50),
last_name VARCHAR2(50),
hire_date DATE,
salary NUMBER
);

Click on the Run button to execute the SQL command and create the new table.
You should see a message indicating that the table was created successfully.
You can now use the table in your Apex application by referencing it in SQL queries, forms, reports, and other components.
Note: You will need to have the necessary privileges and permissions to create tables in your Oracle Apex account. If you are not sure whether you have these privileges, contact your administrator or refer to the Oracle Apex documentation for more information.





Oracle provides a variety of datatypes to store different types of data in its
database. Here are some of the most common Oracle datatypes:

NUMBER: This datatype is used to store numeric data, including integers and decimal numbers. It can be defined with precision and scale to control the number of digits before and after the decimal point.

VARCHAR2: This datatype is used to store variable-length character strings. It can store up to 4000 bytes of data.

CHAR: This datatype is used to store fixed-length character strings. It can store up to 2000 bytes of data.

DATE: This datatype is used to store dates and times. It includes year, month, day, hour, minute, and second components.

TIMESTAMP: This datatype is used to store timestamps, which are date and time values with greater precision than the DATE datatype.

CLOB: This datatype is used to store large character strings up to 4GB in size.

BLOB: This datatype is used to store binary data up to 4GB in size.

BFILE: This datatype is used to store binary data outside the database in a file on the operating system.

INTERVAL: This datatype is used to store intervals of time or time intervals.

There are also several other datatypes available in Oracle, including XMLType, ROWID, and REF CURSOR. The choice of datatype depends on the nature of the data being stored and the operations that will be performed on it.
