java - Parameter does not exist as a named parameter -

my query this:

query query1 = session.createquery("select c.email contact c c.contactno =:contactno"); query1.setinteger("contactno", 22);

the error got is:

exception in thread "main" java.lang.illegalargumentexception: parameter contactno not exist named parameter in [select c.email contact c c.contactno = ?]

it working fine

query query = session.createquery("select c.email contact c c.contactno = ?"); query.setinteger(0, 22);

why 1st query not working?

query query1 = session.createquery("select c.email contact c c.contactno =:contactno"); query.setparameter("contactno", 22);

try using setparameter instead of setinteger

java hibernate
