declare @a varchar(200) 
set @a= '200710101212 ' 
select convert(varchar(11),cast(left(@a,8) as smalldatetime),120)+stuff(right(@a,4),3,0, ': ')

------解决方案--------------------
declare @Time varchar(100)
set @Time='200710101212'
select(cast(substring(@Time,1,2) + '-' + substring(@Time,3,2)+ '-' + substring(@SendTime,5,2) + ' '+ substring(@SendTime,7,2) + ':' + substring(@SendTime,9,2))as datetime)
------解决方案--------------------
set ANSI_PADDING OFF
declare @a varchar(100)
set @a= '200710101212 '
declare @test varchar(100)
select @test = substring(@a,1,4)+'-'+substring(@a,5,2)+'-'+substring(@a,7,2)+' ' +substring(@a,9,2) + ':'+substring(@a,11,2)
select cast(@test as datetime)
select convert(varchar(50),@test,120);
go

SQL code

declare @i varchar(20)
set @i=200710101212
select
    stuff(stuff(stuff(stuff(@i,11,0,':'),9,0,' '),7,0,'-'),5,0,'-'),
    left(@i,4)+'-'+substring(@i,5,2)+'-'+substring(@i,7,2)+' '+substring(@i,9,2)+':'+right(@i,2),
    convert(varchar(16),convert(datetime,stuff(stuff(@i,11,0,':'),9,0,' ')),120),
    convert(varchar(11),convert(datetime,left(@i,8)),120)+stuff(right(@i,4),3,0,':')
