It's unclear what you want.

If you're trying to match «a string that isn't "Select"», you want 

$s !~ /^Select\z/

If you're trying to match «a string that doesn't contain "Select"», you want 

$s !~ /Select/

[download]

If you're trying to match «any number of characters that don't contain the substring "Select"», you want 

$s =~ /(?:(?!Select).)*/s

[download]

(This last one would normally be used as part of a larger pattern.) 

/(?:(?!STRING).)*/s

[download]
is to 
/STRING/

[download]
as 
/[^CHAR]/

[download]
is to 
/CHAR/
