SQL Server 将一个数据库中所有表复制到另一个数据库中

1.创建resset2数据库，将Company_report20221019数据库中所有表复制到resset2数据库中

CREATE DATABASE resset2
       ON
       PRIMARY
       (
              NAME='resset2_data1',
              FILENAME='D:\database\resset2_data1.mdf',
              SIZE=20MB,
              MAXSIZE=UNLIMITED,
              FILEGROWTH=10%
       ),
       (
              NAME='resset2_Log1',
              FILENAME='D:\database\resset2_log1.ldf',
              SIZE=50MB,
              MAXSIZE=100MB,
              FILEGROWTH=10MB
       );
GO
---定义两个变量，一个是存储表名称的；一个是存储插入语句的
declare @tablename varchar(50),@SQL varchar(500)
---创建游标
declare RessetTest cursor for
---查看数据库中的表名
select name from sysobjects where xtype='u'
---打开游标
open RessetTest
---逐行读取游标中的数据存储到@tablename中
fetch next from RessetTest into @tablename
---查看每一条数据读取是否成功，为0时成功，-1时失败
while @@fetch_status=0
---循环执行@sql中的语句 每次从fetch next from RessetTest into @Tablename中读取一行
       begin
                     SET @Sql='select * into resset2.dbo.'+@TableName +' from  [Company_report20221019].[dbo].'+@TableName
                     Exec (@Sql)
                     fetch next from RessetTest into @Tablename
       end
close RessetTest
deallocate RessetTest
