substring sql interview questions and answers reverse the string without using reverse function in sql server

In a SQL interview, you may be asked to reverse a substring within a string without using the built-in reverse function. To accomplish this, you can iterate through the characters of the substring, starting from the end and appending them to a new string. This process effectively reverses the order of characters. You should be cautious of performance implications, especially with large strings, and understand the importance of maintaining the original string's integrity while reversing the targeted substring. This demonstrates your problem-solving skills and knowledge of string manipulation in SQL.

substring() is a function in many programming languages, including SQL, used to extract a portion of a string based on specified start and end positions, allowing you to work with substrings.
