如何在帶有序列的sql server中創建自定義ID
如何創建具有自定義 ID 的表,例如 BK-0001001 和序列。對不起,我是數據庫新手。所有幫助將不勝感激,謝謝!
您可以在 SEQUENCE 和格式化 DEFAULT CONSTRAINT 之間混合使用:
CREATE SEQUENCE MySequence AS int START WITH 1 INCREMENT BY 1; GO
CREATE TABLE MyTable ( MySeq varchar(20) CONSTRAINT [DF_MyTable_MySeq] DEFAULT FORMAT((NEXT VALUE FOR MySequence), 'BK-000000#'), Foo int, Bar int, CONSTRAINT [PK_MyTable] PRIMARY KEY (MySeq) ); GO
INSERT INTO MyTable (Foo, Bar) VALUES (1,2),(2,3),(3,4),(5,6); GO
SELECT * FROM MyTable; GO
MySeq | 福 | 酒吧 :--------- | --: | --: BK-0000001 | 1 | 2 BK-0000002 | 2 | 3 BK-0000003 | 3 | 4 BK-0000004 | 5 | 6
