merge中using能不能用dblink

[attach_finance]

如题，我在写sql的时候用merge时在using里面使用了dblink，oracle报错提示缺失on关键字，求大神指导

MERGE INTO L2_TB S
USING [e-mail] Y
ON S.ID=(CASE WHEN TRIM(Y.JLHH) IS NOT NULL THEN Y.LSH||LPAD(Y.JLHH,6,'0')
 		 				  ELSE Y.LSH||'000000' END)
WHEN MATCHED THEN
	UPDATE SET(ZHH,KH,XM,SFZH,JSRQSJ,JYRQ,DIC_ID,DIC_MC,KSBM,KSMC,YSGH,YSXM,JSLXBZ)=
              (SELECT B.ZHH,A.KH,B.XM,B.SFZH,A.JSRQSJ,A.JYRQ,A.DIC_ID,C.NAME,A.KSBM,A.KSMC,A.YSGH,A.YSXM,A.JSLXBZ
            			FROM [e-mail] A,[e-mail] B,[e-mail] C
              		WHERE A.KH=B.KH AND A.DIC_ID=C.ID AND LENGTH(A.KH)=9  AND SUBSTR(A.LSH,3,4)='0101';)
WHEN NOT MATCHED THEN 
	INSERT(ZHH,KH,XM,SFZH,JSRQSJ,JYRQ,DIC_ID,JGMC,KSBM,KSMC,YSGH,YSXM,JSLXBZ)
    SELECT B.ZHH,A.KH,B.XM,B.SFZH,A.JSRQSJ,A.JYRQ,A.DIC_ID,C.NAME,A.KSBM,A.KSMC,A.YSGH,A.YSXM,A.JSLXBZ
         FROM [e-mail] A,[e-mail] B,[e-mail] C
         WHERE A.KH=B.KH AND A.DIC_ID=C.ID AND LENGTH(A.KH)=9;
