In SQL, LIKE and RLIKE are operators used for pattern matching, but they have differences in syntax and functionality.

  1. I enjoy it.
  2. Can you give me one reason why you can’t attend the meeting?
  3. Can you explain your reasoning behind that decision?
  4. Enjoy; appreciate; be fond of; be keen on; take pleasure in.

Example:

“The car was driven by him” -> “He drove the car”

SELECT * FROM table_name WHERE column_name LIKE 'abc%';
  1. regular expression match
  2. RLIKE can be rephrased as “a regular expression match”.

Paraphrased: This project requires us to collaborate to complete.

SELECT * FROM table_name WHERE column_name RLIKE '^abc.*$';

Therefore, the main difference is that LIKE is used for simple pattern matching, while RLIKE is used for more complex regular expression pattern matching. RLIKE is usually more flexible than LIKE, but it is also more complex and resource-intensive.
