Mongo查询list数组中一个字段大于特定条数

由于刚刚接触mongodb,很多语法还不是很了解,写的不好的地方请大佬指出 查询的demo数据 { "_id":Object("xxxxxxxx"), "contentList":[ "id":"xxxx", "type":2 ], [ "id":"xxxx", "type":2 ] } 查询方法,使用聚合aggregate查询

SQLSERVER中统计所有表的记录数

利用系统索引表sysindexes中索引ID indid<1的行中的rows列存有该表的行数这一特点.    最后一种方法是利用隐藏未公开的系统存储过程sp_MSforeachtable CREATE TABLE #temp (TableName VARCHAR (255), RowCnt INT) EXEC sp_MSforeachtable 'INSERT INTO #temp SELECT ''?'', COUNT(*) FROM ?' SELECT TableName, RowCnt F

ORACLE,SQLSERVER等数据库如何获取某张表中相同字段最近一条数
