Question

我们如何获得最后插入的值？下面是我插入值的函数。但我想获取最后插入的Id，它是自动递增的。我正在使用PostgreSQL

@Override
public int executeInsertSQLSelect(String sqlQuery) throws HibernateException {

    SQLQuery query = getCurrentSession().createSQLQuery(sqlQuery);

    logger.debug("SQL query to be executed is : " + query);

    int noOfRecordsUpdatedOrDeleted;

    try {
        noOfRecordsUpdatedOrDeleted = query.executeUpdate();


    } catch (HibernateException hbExp) {
        logger.error(String.format(
                "Error occured while executing query without Scalar"
                        + " mapping - %s ", query.getQueryString()), hbExp);
        throw hbExp;
    }
    return noOfRecordsUpdatedOrDeleted;
}

如果您使用的是ms sql server，那么您可以使用OUTPUT

例如

String sqlQuery=insert into employee(employeeName) output values('john')
SQLQuery query = getCurrentSession().createSQLQuery(sqlQuery);
query.getSingleResult()

最后在Java Hibernate中插入了Id
