org.hibernate.QueryParameterException: could not locate named parameter

Question

My project setting are Spring MVC, Hibernate 3.2.x, on MySQL DB

Getting the following error:

org.hibernate.QueryParameterException: could not locate named parameter email

Approach #1:

@Override
public Boolean isExist(String email) {
    boolean flag = false;  
    String hql = "from com.cmgr.beans.UserAccount u where u.email = :email";
    List<UserAccount> result = currentSession().createQuery(hql)
        .setParameter("email", email)
        .list();

    UserAccount userAccount = (UserAccount)result.get(0);
    if (userAccount!=null && userAccount.getEmail().equalsIgnoreCase(email)) {
        flag = true;
    }

    return flag;
}

Approach #2:

 @Override
    public Boolean isExist(String email) {
        boolean flag = false;
        String hql = "from com.cmgr.beans.UserAccount u where u.email = :email";
        List<UserAccount> result = currentSession().createQuery(hql).setString("email", email).list();

        UserAccount userAccount = (UserAccount) result.get(0);
        if (userAccount != null && userAccount.getEmail().equalsIgnoreCase(email)) {
            flag = true;
        }
        return flag;
    }

Answer 1

From what i remember, this is a case of Hibernate reporting the wrong error message. I guess, the actual error is "mapping not found for com.cmgr.beans.UserAccount". Try this query:

String hql = "from com.cmgr.beans.UserAccount";

This probably will show you the correct error message. And once you fix that, you can change it to accept the parameters.

Answer 2

Today i had a similar issue... My entity was not in the scanned packages from Spring. So Hibernate somehow did something but the error message was quite confusing and did not really fit to the real issue. To solve my problem i had to add the entities to the packagescan.
