update v9_hits SET hitsid = REPLACE(hitsid,’c-12-‘,’c-13-‘)

where 1 = ( case when(select COUNT(*) from v9_photo where id=replace(hitsid,’c-12-‘,”))>0 then ‘1’ else ‘0’ end)

update v9_hits SET hitsid = REPLACE(hitsid,’c-12-‘,’c-13-‘)

from v9_hits,v9_photo where id=replece(hitsid,’c-12-‘,”)

这表示用尾号连接,能连接上的就给你修改.
