Q1
True / FalseThe ORDER BY clause is used to sort the result set in ascending order by default.
SQL Code
SELECT *
FROM Employees
ORDER BY EmployeeID;
By default, the ORDER BY clause sorts the result set in ascending order.
Q2
True / FalseYou can use multiple columns in the ORDER BY clause to sort the result set.
SQL Code
SELECT *
FROM Employees
ORDER BY DepartmentID, EmployeeID;
The ORDER BY clause can sort by multiple columns, allowing you to specify the order of sorting.
Q3
True / FalseThe ORDER BY clause can only be used in SELECT statements.
SQL Code
SELECT *
FROM Employees
ORDER BY EmployeeID;
The ORDER BY clause is primarily used in SELECT statements but can also be used in subqueries and other SQL statements.
Q4
True / FalseThe ORDER BY clause must be the last clause in the SELECT statement.
SQL Code
SELECT *
FROM Employees
WHERE DepartmentID = 3
ORDER BY EmployeeID;
The ORDER BY clause should always be the last clause in a SELECT statement.
Q5
True / FalseYou can use the ORDER BY clause in conjunction with the DISTINCT keyword.
SQL Code
SELECT DISTINCT DepartmentID
FROM Employees
ORDER BY DepartmentID;
The ORDER BY clause can be used with the DISTINCT keyword to sort unique records.
Q6
True / FalseThe ORDER BY clause can sort the result set in descending order using the DESC keyword.
SQL Code
SELECT *
FROM Employees
ORDER BY EmployeeID DESC;
Adding the DESC keyword sorts the result set in descending order.
Q7
True / FalseYou can sort the result set by columns that are not included in the SELECT statement.
SQL Code
SELECT EmployeeName
FROM Employees
ORDER BY EmployeeID;
The ORDER BY clause can sort by columns that are not part of the SELECT statement.
Q8
True / FalseThe ORDER BY clause can use expressions to determine the sorting order.
SQL Code
SELECT *
FROM Employees
ORDER BY LEN(EmployeeName);
Expressions, such as LEN(EmployeeName), can be used in the ORDER BY clause to determine the sorting order.
Q9
True / FalseThe ORDER BY clause can sort the result set by alias names.
SQL Code
SELECT EmployeeName AS Name
FROM Employees
ORDER BY Name;
Alias names defined in the SELECT statement can be used in the ORDER BY clause.
Q10
True / FalseThe ORDER BY clause can use the column index to sort the result set.
SQL Code
SELECT EmployeeID, EmployeeName
FROM Employees
ORDER BY 2;
You can use the column index in the ORDER BY clause to sort the result set.
Q11
True / FalseThe ORDER BY clause is case-insensitive when sorting text data.
SQL Code
SELECT *
FROM Employees
ORDER BY EmployeeName;
Sorting text data with the ORDER BY clause is case-insensitive by default.
Q12
True / FalseYou can use the COLLATE keyword with ORDER BY to perform case-sensitive sorting.
SQL Code
SELECT *
FROM Employees
ORDER BY EmployeeName COLLATE Latin1_General_BIN;
The COLLATE keyword can be used with ORDER BY to specify case-sensitive sorting.
Q13
True / FalseORDER BY can sort the result set based on the result of a subquery.
SQL Code
SELECT *
FROM (SELECT * FROM Employees) AS Subquery
ORDER BY EmployeeID;
The ORDER BY clause can sort results based on the result of a subquery.
Q14
True / FalseORDER BY can be used in a UNION query to sort the combined result set.
SQL Code
SELECT EmployeeID
FROM Employees
UNION
SELECT DepartmentID
FROM Departments
ORDER BY EmployeeID;
ORDER BY can sort the combined result set of a UNION query.
Q15
True / FalseThe ORDER BY clause can be used with the OVER() clause to provide a custom sort order within a window function.
SQL Code
SELECT EmployeeID,
RANK() OVER (ORDER BY Salary DESC) AS SalaryRank
FROM Employees;
The ORDER BY clause can be used with the OVER() clause to define a custom sort order within window functions like RANK().
