SQL LIKE wildcard space character

Question

let\'s say I have a string in which the words are separated by 1 or more spaces and I want to use that string in and SQL LIKE condition. How do I make my SQL and tell it to

Answer 1

If your dialect allows it, use SIMILAR TO, which allows for more flexible matching, including the normal regular expression quantifiers '?', '*' and '+', with grouping indicated by '()'

where entry SIMILAR TO 'hello +there'

will match 'hello there' with any number of spaces between the two words.

I guess in MySQL this is

where entry RLIKE 'hello +there'
