如何编写 oracle sql 来查找特殊字符

Question

I'm trying to search a varchar string for these specific characters. ^$<> I tried using regexp_like() , but I can't figure out to only show the records that have those characters (since ^ and $ are used to determine something else in that function).
My data is a title field - so I only want to see the titles that have any of those characters. Thanks!

Answer 1

You should use

where col REGEXP_LIKE '[$^<>]'

Note that ^ is a negation marker when used as the first symbol inside a bracket expression, so it should be placed at the non-initial position.

Also, there is no need to add any .* to the pattern since REGEXP_LIKE is able to perform a partial match (ie there is no obligation to match the whole record).
