SQLite 设置自增列、重置自增列

创建表

设置主键自增

CREATE TABLE [tCeShi](
  [ID] INTEGER PRIMARY KEY AUTOINCREMENT, 
  [Name] TEXT(50), 
  [Amount] REAL);

插入数据

主键位置写成NULL

insert into tCeShi values(NULL, '商品A', 10);

或不插入主键

insert into tCeShi(Name, Amount) values('商品B', 20);

重置自增列

查询自增列内部表

select * from sqlite_sequence

重置为空

delete from sqlite_sequence where name = 'tCeShi' 

或设为指定值

update sqlite_sequence set seq = 100 where name = 'tCeShi'
