执行随附的代码时，我收到一个 SQLGrammarException，没有进一步的解释。我正在对 mysql 数据库执行此代码。有人能理解这个查询有什么问题吗？
public PatientId getPatientByAccount(String account_) {
Session session = null;
PatientId patient = null;
try {
session = HibernateUtils.beginTransaction("emscribedx");
session.beginTransaction();
String queryString = "from PatientId where acct = :acct";
Query query = session.createQuery(queryString);
query.setString("acct", account_);
Object queryResult = query.uniqueResult();
patient = (PatientId)queryResult;
session.getTransaction().commit();
} catch (HibernateException e_) {
System.out.println("Problem getting patientId for acct=" + account_
+ " " + e_.toString());
NTEVENT_LOG.error("Problem getting patientId for acct=" + account_
+ " " + e_.getStackTrace());
} finally {
if (session != null && session.isOpen()) {
try {
HibernateUtils.closeSessions();
} catch (HibernateException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
return patient;
}
如果有帮助，查询将生成以下 sql：
