Hibernate setParameter 将单引号添加到字符串

Question

我正在尝试使用休眠准备语句创建新表。看起来"setparameter("values", value)" 为查询添加了额外的引号。 我的代码：

String hql = "create table :values " + "(name VARCHAR(50))";
        Query my = session.createSQLQuery(hql);
        my.setParameter("values", value);
        my.executeUpdate();
        session.close();

错误：

SEVERE: Servlet.service() for servlet [contextServlet] in context with path [/SpringSafeHouseService2.0] threw exception [Request processing failed; nested exception is org.hibernate.exception.SQLGrammarException: could not execute statement] with root cause
com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ''merkurijuss' (name VARCHAR(50))' at line 1

您不能在准备好的语句中使用表名作为参数。您必须将其放入刺痛中：

    String hql = "create table "+ value+ " (name VARCHAR(50))";
    Query my = session.createSQLQuery(hql);
    my.executeUpdate();
    session.close();
