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
