AdventureWorks Database: Remove spaces at the end of a string

SQL Query - AdventureWorks: Exercise-71 with Solution

71. Write a query in SQL to remove the spaces at the end of a string.

Sample Solution:

-- Concatenating the string 'text then five spaces     ' with 'after space' and aliasing it as "Original Text"
SELECT CONCAT('text then five spaces     ','after space') as "Original Text",

-- Concatenating the trimmed version of the string 'text then five spaces     ' with 'after space' and aliasing it as "Trimmed Text(space removed)"
CONCAT(RTRIM('text then five spaces     '),'after space') as "Trimmed Text(space removed)";

Explanation:

• The SQL query concatenates two strings together and provides two variations of the concatenation.
• In the first concatenation:
• The CONCAT() function concatenates the string 'text then five spaces ' with 'after space'.
• The result is aliased as "Original Text".
• In the second concatenation:
• The RTRIM() function trims any trailing spaces from the string 'text then five spaces '.
• The CONCAT() function then concatenates the trimmed string with 'after space'.
• The result is aliased as "Trimmed Text(space removed)".

Sample Output:

Original Text                        |Trimmed Text(space removed)     |
-------------------------------------+--------------------------------+
text then five spaces     after space|text then five spacesafter space|
