In Java, suppose I have a String variable S, and I want to search for it inside of another String T, like so: if (T.matches(S)) ... (note: the above line was T.contains() until a few posts pointed out that that method does not use regexes. My bad.) But now suppose S may have unsavory characters in it. For instance, let S = "[hi"...
Hello, I need to do a query that search for a text with 'Nome % teste \ / ' as prefix. I'm doing the query using: where "name" ILIKE 'Nome a% teste \ /%' ESCAPE 'a' (using a as scape character).
