我的数据库更改为Oracle到MySQL。在MySQL中合并替代

Question

Oracle查询：

MERGE into CMDASHBOARD x using
(
  SELECT  
    COUNT(C.CMHBASEROWKEYID_PK) count ,
    c.CLUSTERID_FK ,
    c.BAND 
  FROM CMHBASEROWKEY C 
  WHERE  (C.SICOUNT+C.NSICOUNT) = 0
    AND C.HIERARCHY = 'CELL' 
    AND TRUNC(C.MODIFIEDTIME) = TRUNC(sysdate) 
    AND C.SITETYPE != 'SMALL_CELL'
  GROUP by c.CLUSTERID_FK , c.BAND
) y on( x.CLUSTERID_FK = y.CLUSTERID_FK and x.BAND=y.band )
when matched then UPDATE set x.SECTORCOMPLIANTCOUNT = y.count 
                  WHERE TRUNC(x.CREATEDDATE) = TRUNC(sysdate);

我试过这个：

insert into CMDASHBOARD (SECTORCOMPLIANTCOUNT) 
  select COUNT(s.CMHBASEROWKEYID_PK) count, s.CLUSTERID_FK, s.BAND 
  from CMHBASEROWKEY s 
  JOIN CMDASHBOARD p ON p.CLUSTERID_FK= s.CLUSTERID_FK and p.BAND=s.band 
  where (s.SICOUNT+s.NSICOUNT)=0 
    AND s.HIERARCHY ='CELL' 
    AND s.SITETYPE != 'SMALL_CELL' 
    AND s.MODIFIEDTIME=sysdate() 
  GROUP by s.CLUSTERID_FK ,s.BAND;
  ON DUPLICATE KEY UPDATE SECTORCOMPLIANTCOUNT= summ;
