使用文中提供的代码做一个统计表每天的新增行数及新增存储空间的功能

实现步骤如下：

1. 创建表

创建表，存储每天的表空间占用情况

CREATE TABLE [dbo].[t_rpt_table_spaceinfo](
[table_name] [sysname] NOT NULL,
[record_date] [date] NOT NULL,
[record_time] [time](7) NOT NULL,
[rows_count] [bigint] NULL,
[reserved] [bigint] NULL,
[data_size] [bigint] NULL,
[index_size] [bigint] NULL,
[unused] [bigint] NULL,
CONSTRAINT

PRIMARY KEY CLUSTERED
(
[table_name] ASC,
[record_date] ASC,
[record_time] ASC
)
)

2. 新建作业
