Question

我们在项目中使用ppas9.3数据库和hibernate3。我们正在使用一种已经调用其他两种方法的方法。在一种方法中，我们正在执行＆＃39;选择＆＃39;查询（由于'column doesn't exist'而无法执行）并且在关闭此连接（即jdbc连接）之后，我们正在调用第一个在第一次失败后执行的方法，这次我们使用{{1}进行连接并且当执行select查询（即在数据库中成功执行）时，会出现以下错误： -

'HibernateUtils.getCurrentSession().connection'

当第一个语句没有抛出任何错误时，第二个也正常工作。我检查的是： - 1.我在执行第一个语句之前使用了一个保存点，如果出现错误则回滚到该保存点。 2.试图在没有保存点的情况下回滚。但每次在第二种方法中都会出错。方法代码是： -

nsaction.RollbackException: Transaction TransactionImple < ac, BasicAction: a0028c9:d2ba:53c51ef5:6e4 status: ActionStatus.ABORT_ONLY > cannot proceed STATUS

第一种方法是： -

private String buildItems() {
        try {
            loadItemsForInfos();
            addItems();
        } catch (RuntimeException e) {
            e.getPrintStack();
        }
    }

和第二种方法是： -

public void loadValueForInfos(){
    ResultSet rs = null;
    Connection conn = getDSConnection(); // we are taking connection through JNDI name.
    PreparedStatement pst = conn.prepareStatement("select * from items where id = ?")//this query by default fails to execute.
    pst.setObject(1,12);
    try{
    rs = executeQuery();
    while (rs.next()){
    //have some code..
    }
    }catch(SQLException e){

    } finally {
                SqlUtils.closeResources(pst, rs);
            }

只有当第一个查询无法执行时才会出现此错误，即使第二个查询正确也意味着执行成功。
我们正在使用public void addItems() { String query = "select * from particularitems where id = ?"; PreparedStatement stmt = null; ResultSet rs = null; Connection conn = null; try { conn = HibernateUtil.currentSession().connection(); stmt = conn.prepareStatement(query); stmt.setInt(1, 34); rs = stmt.executeQuery(); while (rs.next()) { } } catch (Exception se) { throw new Exception(se); } finally { SqlUtils.closeResources(stmt, rs); } }

那么请你告诉我确切的原因以及如何解决它。谢谢你，

经过一个多月的谷歌搜索和R＆amp; D之后，我终于通过在PPAS9.3 postgresql中将“edb_stmt_level_tx = off”的值设置为“on”来修复上述postgresql 9.3的常见错误。 .config属性文件。欲了解更多信息，请访问以下链接。
