![]() Tilde (~) operator helps the regular expression to be matched in any part of the string easily. Hey, I think this helps because I was trying to go to websites to see how I could do the upside-down (inverted) question mark and this helps. Tilde regular expressions are more powerful in comparison to LIKE and SIMILAR TO operators. ![]() LIKE operator works best with full strings and if a substring or a small part within a string needs to be matched then in that case the pattern must contain (%) at the beginning of substring and at the end of substring as well. Underscore (_) in above example basically looks for only single character match and percentage (%) looks for none, single or multiple characters match. In the above examples you see, the literal pattern, without percentage and underscore signs, means the string itself would be considered as a pattern and it’s working like and equal sign and matches input letter by letter.
