mysql、sqlserver关联表批量修改

一、mysql关联表批量修改

UPDATE sp_sys_dictionaries_category a   #根据对应id，把b.username的值赋给a.username
LEFT JOIN sp_sys_dictionaries b ON b.cid = a.id
SET a.username = b.username

 

二、sqlserver关联表批量修改

UPDATE a SET a.FLONGYARN = b.ORGID    --根据对应id，把b.ORGID的值赋给a.FLONGYARN
FROM ST_LongYarn a
LEFT JOIN ST_InspectionRecordOfCaloco b ON b.fid = a.fid
