Question

我遇到了一个问题，我的日志文件在我的合并完成之前就已经填满了。有没有办法我可以迭代这个合并，一次合并1000，提交，然后重新开始？这是我的合并声明：

MERGE INTO "SCHEMA"."PATIENT" AS DMT
USING "SCHEMA"."PATIENT_STAGE" AS Stage
ON ( DMT.MEMBER_ID = Stage.MEMBER_ID)
when matched then 
update set 
DMT.MEMBER_ID = Stage.MEMBER_ID, 
DMT.ADDRESS1 = Stage.ADDRESS1, 
DMT.ADDRESS2 = Stage.ADDRESS2,
DMT.BENEFIT_ID = Stage.BENEFIT_ID, 
DMT.CITY = Stage.CITY, 
DMT.STATE = Stage.STATE,
DMT.CLIENT_CLIENT_ID = Stage.CLIENT_CLIENT_ID,
DMT.CLIENT_CUSTOMER_ID = Stage.CLIENT_CUSTOMER_ID, 
DMT.CLIENT_GROUP_ID = Stage.CLIENT_GROUP_ID, 
DMT.DATE_OF_BIRTH = Stage.DATE_OF_BIRTH,
DMT.FIRST_NAME = Stage.FIRST_NAME, 
DMT.GENDER = Stage.GENDER, 
DMT.LAST_NAME = Stage.LAST_NAME,
DMT.MIDDLE_NAME = Stage.MIDDLE_NAME, 
DMT.PERSON_CODE = Stage.PERSON_CODE, 
DMT.SSN = Stage.SSN,
DMT.TPL_PAYOR = Stage.TPL_PAYOR, 
DMT.TPL_PRIM_NAME = Stage.TPL_PRIM_NAME, 
DMT.UPDATE_DATE = Stage.UPDATE_DATE;
COMMIT;

这似乎解决了我的问题：

num=1 ; while ((num < 100000)) ; do

MERGE INTO "SCHEMA"."PATIENT" AS DMT
USING "SCHEMA"."PATIENT_STAGE" AS Stage
update set 
DMT.MEMBER_ID = Stage.MEMBER_ID, 
DMT.ADDRESS1 = Stage.ADDRESS1, 
DMT.ADDRESS2 = Stage.ADDRESS2,
DMT.BENEFIT_ID = Stage.BENEFIT_ID, 
DMT.CITY = Stage.CITY, 
DMT.STATE = Stage.STATE,
DMT.CLIENT_CLIENT_ID = Stage.CLIENT_CLIENT_ID,
DMT.CLIENT_CUSTOMER_ID = Stage.CLIENT_CUSTOMER_ID, 
DMT.CLIENT_GROUP_ID = Stage.CLIENT_GROUP_ID, 
DMT.DATE_OF_BIRTH = Stage.DATE_OF_BIRTH,
DMT.FIRST_NAME = Stage.FIRST_NAME, 
DMT.GENDER = Stage.GENDER, 
DMT.LAST_NAME = Stage.LAST_NAME,
DMT.MIDDLE_NAME = Stage.MIDDLE_NAME, 
DMT.PERSON_CODE = Stage.PERSON_CODE, 
DMT.SSN = Stage.SSN,
DMT.TPL_PAYOR = Stage.TPL_PAYOR, 
DMT.TPL_PRIM_NAME = Stage.TPL_PRIM_NAME, 
DMT.UPDATE_DATE = Stage.UPDATE_DATE(select........where <> fetch 1st 1000 rows only )
(num=num+1)
done
