How to create and input data into a table in PostgreSQL?

To create and input table data in PostgreSQL, you can follow these steps:

1. Open the PostgreSQL command-line interface or use a graphical interface tool (such as pgAdmin) to connect to the PostgreSQL database.
2. To create a table structure, use the CREATE TABLE statement to define the columns and data types of the table. For example, create a table named “students” with columns “id” (integer), “name” (string), and “age” (integer).
3. Create a table for students with columns for id (auto-incrementing), name (string of up to 50 characters), and age (whole number).
4. Inserting data:
   Use the INSERT INTO statement to insert data into a table. For example, insert a record into the “students” table.
5. Add John, who is 20 years old, to the students table.
6. You can insert multiple rows of data by executing the INSERT INTO statement multiple times.
7. Retrieve table data:
   Utilize the SELECT statement to retrieve data from a table. For example, retrieve all data from the “students” table.
8. Show all the records from the students table.
9. You can also search for data based on certain conditions, for example, searching for students who are 18 years old or older.
10. Retrieve all students who are 18 years old or older.
11. This will allow you to create and enter table data.
