--drop table #UserDB

--drop table #DB_Role

 

Create table #DB_Role

(

                      select name from sys.databases where name not in

批量对数据库进行TDE加密：

use master;
go
if not exists
   (select * from sys.databases where name=N‘master‘ and is_master_key_encrypted_by_server=1)
create master key
   encryption by password=‘Password1‘;

   (select * from sys.certificates where name=‘TDE_cert‘)
create certificate TDE_cert
   with subject=‘TDE certificate‘;
go
use master;
go
backup certificate TDE_cert to file=‘C:\TDE_Files\TDE_cert‘
   with private key
   (file=‘C:\TDE_Files\TDE_private_key‘,
   encryption by password=‘Password2‘
   )

Create table #UserDB
(name varchar(1000));
insert into #UserDB
   select name from sys.databases where name not in
                (N‘master‘, N‘model‘, N‘msdb‘, N‘tempdb‘, N‘distribution‘, N‘DWDiagnostics‘, N‘DWConfiguration‘, N‘DWQueue‘, N‘resource‘,N‘ReportServer‘,N‘ReportServerTempDB‘)

set @TDE_SQL=

 create database encryption key
   with algorithm=AES_256
   encryption by server certificate TDE_cert;

print @TDE_SQL;
exec (@TDE_SQL)
fetch next from TDE_Cursor into @UserDB;
end
close TDE_Cursor;
deallocate TDE_Cursor;

 

游标对所有列进行有效信息筛选（每个字段有相同的关键字时）：

Use [ITSP_Audit]

--drop table #Failed_List

--drop table #Column

Declare @Columns varchar(100)

create table #Failed_List

(Server_Name varchar(100),

Failed_Item Varchar(100)

)

 

Declare ColumnName cursor for

select name from sys.columns where OBJECT_ID=object_id(‘AuditItem‘)

open ColumnName;

Fetch next from ColumnName into @Columns;

while @@FETCH_STATUS=0

Begin

insert into #Column select @Columns

set @SQL=‘Insert into #Failed_List

Exec (@SQL)

fetch next from ColumnName into @Columns;

end

close ColumnName

deallocate ColumnName

 

select * from #Failed_List order by Server_Name,Failed_Item
