I want to execute a simple native query, but it does not work:
@Autowired
private EntityManager em;
Query q = em.createNativeQuery("SELECT count(*) FROM mytable where username = :username");
em.setProperty("username", "test");
(int) q.getSingleResult();
Why am I getting this exception?
org.hibernate.QueryException: Not all named parameters have been set: [username]
You are calling setProperty
instead of setParameter
. Change your code to
Query q = em.createNativeQuery("SELECT count(*) FROM mytable where username = :username");
em.setParameter("username", "test");
(int) q.getSingleResult();
and it should work.
Use set Parameter from query.
Query q = (Query) em.createNativeQuery("SELECT count(*) FROM mytable where username = ?1");
q.setParameter(1, "test");
This was a bug fixed in version 4.3.11 https://hibernate.atlassian.net/browse/HHH-2851
EDIT: Best way to execute a native query is still to use NamedParameterJdbcTemplate It allows you need to retrieve a result that is not a managed entity ; you can use a RowMapper and even a Map of named parameters!
private NamedParameterJdbcTemplate namedParameterJdbcTemplate;
@Autowired
public void setDataSource(DataSource dataSource) {
this.namedParameterJdbcTemplate = new NamedParameterJdbcTemplate(dataSource);
}
final List<Long> resultList = namedParameterJdbcTemplate.query(query,
mapOfNamedParamters,
new RowMapper<Long>() {
@Override
public Long mapRow(ResultSet rs, int rowNum) throws SQLException {
return rs.getLong(1);
}
});
I use EclipseLink. This JPA allows the following way for the native queries:
Query q = em.createNativeQuery("SELECT * FROM mytable where username = ?username");
q.setParameter("username", "test");
q.getResultList();
After many tries I found that you should use createNativeQuery
And you can send parameters using #
replacement
In my example
String UPDATE_lOGIN_TABLE_QUERY = "UPDATE OMFX.USER_LOGIN SET LOGOUT_TIME = SYSDATE WHERE LOGIN_ID = #loginId AND USER_ID = #userId";
Query query = em.createNativeQuery(logQuery);
query.setParameter("userId", logDataDto.getUserId());
query.setParameter("loginId", logDataDto.getLoginId());
query.executeUpdate();
