839139 Maria           Foster                  57
```

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:

```First Name	Last Name	Department	Amount Allotted
Alan		Snappy		RD		55000
Maria		Foster		IT		65000
Michale		Robbin		IT		65000
Carlos		Snares		Finance		15000
Enric		Dosio		IT		65000
Jhon		Snares		Finance		15000
Joseph		Dosni		HR		240000
Zanifer		Emily		HR		240000
Kuleswar	Sitaraman	IT		65000
Henrey		Gabriel		HR		240000
Alex		Manuel		IT		65000
George		Mardy		RD		55000
Mario		Saule		Finance		15000
```

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.
