BoneCp池具有已关闭的连接

我正在使用带有光滑的Bonecp数据源.并发现池包含已关闭的连接,因此我总是遇到此异常

分组依据选择不起作用

我有两个表,我的外部选择聚合所有那些存在于我放在where子句中的另一个表中的id.两个表都是使用通配符函数生成的.以下是查询 -

SELECT count(id), timestamp  FROM (TABLE_QUERY(dataset1, 'expr'))  
WHERE id IN (SELECT id FROM (TABLE_QUERY(dataset1, 'expr')) 
WHERE timestamp < 1414670361836)  ) group by timestamp
