有一个SQL:
select coalesce(count(1),0) from table where searchDt=#searchDt#
ibatis Dao层是这么写的:
public Integer findCount(String searchDt) throws SQLException { return (Integer)this.get().queryForObject("xxxxx",searchDt); }
现在提示错误:
java.sql.SQLException: Error: executeQueryForObject returned too many results. at com.ibatis.sqlmap.engine.mapping.statement.GeneralStatement.executeQueryForObject(GeneralStatement.java:108) at com.ibatis.sqlmap.engine.impl.SqlMapExecutorDelegate.queryForObject(SqlMapExecutorDelegate.java:566) at com.ibatis.sqlmap.engine.impl.SqlMapExecutorDelegate.queryForObject(SqlMapExecutorDelegate.java:541) at com.ibatis.sqlmap.engine.impl.SqlMapSessionImpl.queryForObject(SqlMapSessionImpl.java:106) at com.ibatis.sqlmap.engine.impl.SqlMapClientImpl.queryForObject(SqlMapClientImpl.java:83) at com.boco.monitor.dao.xxxxDao.findCount(xxxxDao.java:112) at com.boco.monitor.service.xxxxService.xxxxAnalysis(xxxxService.java:882) at com.boco.monitor.task.Task.run(Task.java:35) at java.util.TimerThread.mainLoop(Timer.java:555) at java.util.TimerThread.run(Timer.java:505)
奇了怪了,这SQL打死也不能查出多条结果啊?
付费偷看金额在0.1-10元之间

提示已经很清楚了。
queryForObject
只需要1条记录,但实际返回了多条记录。确认一下传入的参数searchDt名字和值有没有问题
