매일 열 값 재설정

Question

내 열을 매일 1000 개 이상 시작해야합니다. 모든 새 항목에 대해이 숫자는 1 씩 증가합니다. 다음 날에는 다시 1000으로 되돌려 야합니다. 어떻게해야합니까?

가정하자 테이블 이름 '된 table_1'

자동 증분 열 이름

DECLARE @NewId int = 0 

IF EXISTS (select * from Table_1 where EntryDate=GETDATE() and ID=1000) 
    @NewId = (select max(ID) from Table_1) + 1 
ELSE 
    @NewId = 1000 

INSERT INTO TABLE_1(ID,EntryDate) VALUES (@NewId,GETDATE()) 

(된 table_1이 칼럼을 가정) 'ID'

날짜 열 이름 'EntryDate'임
