csharp:SQLite and Access using C# code read data

SQLite sql script:

CREATE TABLE BookKindList
(
	BookKindID INTEGER PRIMARY KEY AUTOINCREMENT,
	BookKindName varchar(500) not null,
           BookKindCode varchar(100) null,
	BookKindParent int null
)

--添加
insert into BookKindList(BookKindName,BookKindCode,BookKindParent) values('目录','0003',1);
--查询
select * from BookKindList;

select * from BookKindList where BookKindList.BookKindID=2;
--删除
delete from BookKindList where BookKindList.BookKindID=3;
--更新
update  BookKindList set BookKindName='文学',BookKindCode='0002',BookKindParent=1 where BookKindID=2;

--返回添加自增ID
select last_insert_rowid();
