Sample Solution:
-- Selecting specific columns and renaming them for clarity
SELECT emp_details.emp_fname AS "First Name", emp_lname AS "Last Name",
emp_department.dpt_name AS "Department",
dpt_allotment AS "Amount Allotted"
-- Specifying the tables to retrieve data from ('emp_details' and 'emp_department')
FROM emp_details
-- Performing an inner join based on the equality of 'emp_dept' in 'emp_details' and 'dpt_code' in 'emp_department'
INNER JOIN emp_department
ON emp_details.emp_dept = emp_department.dpt_code;
Output of the Query:

Explanation:
The said SQL query is selecting the employee's first name (emp_details.emp_fname) with an alias 'First Name', last name (emp_lname) with an alias 'Last Name', department name (emp_department.dpt_name) with an alias 'Department', and department allotment (dpt_allotment) with an alias 'Amount Allotted' by joining the emp_details table and emp_department table on the emp_dept column of the emp_details table and the dpt_code column of the emp_department table. The query is joining the two tables together and displaying the selected columns from both tables.
