我尝试使用SYS查询生成50-100个表
SELECT windows_release, windows_service_pack_level,
windows_sku, os_language_version
FROM sys.dm_os_windows_info OPTION (RECOMPILE); -- DE????RSE INSERT ETSIN AYNI ISE DE???MES?N
-- Gives you major OS version, Service Pack, Edition, and language info for the operating system
-- SQL Server Services information (SQL Server 2008 R2 SP1 or greater)
SELECT servicename, startup_type_desc, status_desc,
last_startup_time, service_account, is_clustered, cluster_nodename
FROM sys.dm_server_services OPTION (RECOMPILE);
-- Hardware information from SQL Server 2008
-- (Cannot distinguish between HT and multi-core)
SELECT cpu_count AS [Logical CPU Count], hyperthread_ratio AS [Hyperthread Ratio],
cpu_count/hyperthread_ratio AS [Physical CPU Count],
physical_memory_in_bytes/1048576 AS [Physical Memory (MB)],
sqlserver_start_time --, affinity_type_desc -- (affinity_type_desc is only in 2008 R2)
FROM sys.dm_os_sys_info OPTION (RECOMPILE);

如何从SYS表查询结果创建表?

你可以这样做.
SELECT windows_release, windows_service_pack_level,
windows_sku, os_language_version
into new_table_name
FROM sys.dm_os_windows_info OPTION (RECOMPILE);

使用子选择的示例语句:
select * into MyNewTable
from
(
select
*
from
[SomeOtherTablename]
where
EventStartDatetime >= '01/JAN/2018'
)
) mysourcedata
;

请注意,子查询必须指定一个名称.. 任何名称.. 例如,上面的示例为子查询命名为 mysourcedata。如果没有这个,SQL*server 2012 中会出现语法错误。
数据库应回复如下消息:(9999 行受影响)
