统计主表关联的满足一定条件的子表数量
统计主表关联的子表数量：
其中znld是主表的id；
主表：specialcase
子表：to_zhuanan_xsczqk，to_zhuanan_xckcqz

String cxfSql = "select ((select count(*) from to_zhuanan_xsczqk a,specialcase b where a.zhuanan_id=b.id and a.xsczqksj>=to_date('"+ time1+ "','yyyy-MM-dd') and a.xsczqksj<=to_date('"+ time2+ "','yyyy-MM-dd') and b.id= '"
