一段输出代码本身的SQL代码

declare @text nvarchar(max);
with tb
as
(
select blocking_session_id,
session_id,db_name(database_id) as dbname,text from master.sys.dm_exec_requests  a
CROSS APPLY master.sys.dm_exec_sql_text(a.sql_handle)
),
tb1 as
(
select a.*,login_time,program_name,client_interface_name,login_name,cpu_time,memory_usage*8 as 'memory_usage(KB)',
total_scheduled_time,reads,writes,logical_reads 
from tb a inner join master.sys.dm_exec_sessions b
on a.session_id=b.session_id
)
select @text=text from tb1 a inner join master.sys.dm_exec_connections b on a.session_id=b.session_id 
print @text

/*

with tb
as
(

session_id,db_name(database_id) as dbname,text from master.sys.dm_exec_requests  a
CROSS APPLY master.sys.dm_exec_sql_text(a.sql_handle)

tb1 as
(
select a.*,login_time,program_name,client_interface_name,login_name,cpu_time,memory_usage*8 as 'memory_usage(KB)',
total_scheduled_time,reads,writes,logical_reads

on a.session_id=b.session_id
)
select @text=text from tb1 a inner join master.sys.dm_exec_connections b on a.session_id=b.session_id 
print @text
*/

还可以短一点：

declare @text nvarchar(max);

select @text=text 
from master.sys.dm_exec_requests  a
CROSS APPLY master.sys.dm_exec_sql_text(a.sql_handle)

print @text

/*
declare @text nvarchar(max);

select @text=text 
from master.sys.dm_exec_requests  a
CROSS APPLY master.sys.dm_exec_sql_text(a.sql_handle)

print @text
