sqlserver怎么查询所有表数据量

要查询所有表的数据量，可以使用以下SQL查询:

SELECT     t.NAME AS TableName,    SUM(p.rows) AS RowCountsFROM     sys.tables tINNER JOIN          sys.indexes i ON t.OBJECT_ID = i.object_idINNER JOIN     sys.partitions p ON i.object_id = p.OBJECT_ID AND i.index_id = p.index_idWHERE     i.index_id <= 1GROUP BY     t.NAMEORDER BY     SUM(p.rows) DESC;

这条查询会返回所有表的名称以及每个表的数据量。
