PostgreSQL Basic SELECT Statement: Select first ten records from a table
18. Write a query to select first ten records from a table.
Sample Solution:
Code:
-- Selecting the employee ID and first name from the employees table, limiting the result to the first 10 rows
SELECT employee_id, first_name
-- Selecting data from the employees table
FROM employees
-- Limiting the result set to the first 10 rows
LIMIT 10;
Explanation:
- This SQL code selects the employee ID and first name from the "employees" table.
- It limits the result set to include only the first 10 rows using the LIMIT clause.
- The result set will contain employee IDs and first names for the first 10 employees in the employees table, based on the default ordering of the table.
Sample table: employees
Output:
pg_exercises=# SELECT employee_id, first_name
pg_exercises-# FROM employees LIMIT 10;
employee_id | first_name
