SELECT command/query is used to fetch data from the database/table. We can either fetch some columns or fetch an entire table. As select is a query that means it returns some data which is actually got stored in another table called result-set.

Syntax:

SELECT column1, column2,... FROM table_name;

Here,
column1, column2,... are the name of the fields in the table.
table_name is the name of the table from which we want to fetch data.

Queries

1. Query to fetch an entire table

SELECT * FROM Student;

We can also write all field names instead of "*" but that would be quite tedious to write all of the field names
