Quick Regex Question

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi all,

I don't understand the last result:

select 'Ho Ho Ho' ~* '^Ho'; returns true
select 'Ho Ho Ho' ~* ' Ho'; returns true
select 'Ho Ho Ho' ~* '[^ ]Ho'; returns false (Please note there is a space between ^ and ])

From my limited experience of regex, the last one is searching for either
   'Ho' preceeeded by space or
   'Ho' at the beginning of a string.

How come it returns false?

Thanks.

P.S. The Ho's are Santa type Ho's - Not the other kind.
