How can I interpolate a Perl hash element in a string?

Question

How to print a hash from a string, as in

print "\n[*] Query : $select { query }"; 

against

 print "\n[*] Query : " . $select { query }; 

Answer 1

You may need to remove the extra spaces:

 print "\n[*] Query : $select{query}"; 

With a space after $select Perl thinks what you did with the interpolation of this variable and literally interpret the following text (including curly braces).
