求助：程序连接informix数据库的表：
使用java程序 执行:
StringBuffer sf=new StringBuffer();
sf.append("select new com.jy.pjbj.dto.manhour.EvalQuickDefaultUserDTO(a.id,a.qybm,a.qymc,a.bz) " +
"from PjZdQyzdBd a,PjZdQyzd xtqy " +
"where a.scbz = '0' and xtqy.scbz = '0' and a.xtqyId = xtqy.id ");
sf.append(" order by a.qybm ");
List returnList = pm.getList(sf.toString());
就报如下错误：
org.springframework.jdbc.UncategorizedSQLException: (Hibernate operation): encountered SQLException [Cannot add index.]; nested exception is java.sql.SQLException: Cannot add index.

抓出Sql在数据库直接查询
select a.id,a.qybm,a.qymc,a.bz
from Pj_Zd_Qyzd_Bd a,Pj_Zd_Qyzd xtqy
where a.scbz = '0' and xtqy.scbz = '0' and a.xtqyId = xtqy.id
order by a.qybm
直接执行，可以正常查询，
高手帮忙给看下啊
