这个sql放在数据库里执行没有问题。为哈程序一执行就报错了。
sql:
sql = Sqls.queryRecord("select * from activity apt where is_remove=0 and type=1 and CURDATE()<apt.endDate ORDER BY id desc");
异常:
Caused by: 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 'CURDATE()<endDate' at line 1

报错信息跟sql不太一样吧?

CURDATE()<apt.endDate use near 'CURDATE()<endDate' at line 1

@wendal 嗯,apt.是我发帖的时候加上去的,标明下是表的属性哈哈,不知道这是什么情况

那你还得在贴一次真正的代码

@wendal

             if (curPage == 0) {
            curPage = 1;
        }
        try {
            Pager pager = dao.createPager(curPage, 10);//当前页,每页显示的个数,
            sqlCount = Sqls.fetchInt("select count(*) from activity  where  is_remove=0 and type=1and  CURDATE()<apt.endDate");//设置sql查询条件
            pager.setRecordCount(dao.execute(sqlCount).getInt());//得到查询出来的总记录数,放入page对象

            sql = Sqls.queryRecord("select * from activity apt  where  is_remove=0 and type=1 and CURDATE()<apt.endDate ORDER BY id desc");
            sql.setPager(pager);
            dao.execute(sql);
            List<Record> list = sql.getList(Record.class);
            map.put("recordList",list);
            map.put("pager",pager);
            map.put("result",1);
        } catch (Exception e) {
            e.printStackTrace();
            map.put("result",2);
        }

下面是异常信息:

@wendal 我找到原因了 and type=1and CURDATE()<apt.endDate。。1和and中没有空格

@qq_c6efc20e 一个空格引发的血案
