前提:两张表要更新的字段、关联字段结构一致
更新库:FJPDI_TZGL
提取库:FJPDI_TZGL_29
表:DataChangesTempT
更新字段:REASON
关联字段:IID
目标:把FJPDI_TZGL_29中DataChangesTempT的REASON字段更新到FJPDI_TZGL_中DataChangesTempT的REASON字段
查询语句:
SELECT IID,REASON FROM FJPDI_TZGL.dbo.DataChangesTempT SELECT IID,REASON FROM FJPDI_TZGL_29.dbo.DataChangesTempT
更新语句:
UPDATE FJPDI_TZGL.dbo.DataChangesTempT SET REASON= d.REASON FROM FJPDI_TZGL_29.dbo.DataChangesTempT d WHERE FJPDI_TZGL.dbo.DataChangesTempT.IID=d.IID
