记开发个人图书收藏清单小程序开发(十)DB开发

文章作者:开户送38体验金不限id数据库 上传时间:2019-08-22

昨晚完成了Web端新增图书信息的功能,现在就差DB的具体实现了。

因为我把Book相关的信息拆分的比较多,所以更新有点小麻烦。

首先,我需要创建一个Book Type的Matter;

然后,将图片路径保存到FileBank中,并返回FileBankID;

继续,插入Publisher信息(需要判断name不存在才会insert),然后返回PublisherID;

 1 CREATE PROCEDURE [base].[Publisher#Insert](@json nvarchar(max), @id int out)
 2 WITH ENCRYPTION
 3 AS
 4 BEGIN
 5 ...
 6 
 7         declare    @name nvarchar(100);
 8         select    @name=Publisher from openjson(@json, '$') with (Publisher nvarchar(100))
 9 
10         -- insert Publisher
11         insert    base._Publisher(Name)select @name
12         where    not exists(select 1 from base._Publisher p where p.Name=@name);
13 
14         select    @id=ID from base.Publisher#Raw() where Name=@name;
15 ...
16 END

 

开户送38体验金不限id,继续,插入Binding信息(也需要判断name不存在才insert),返回BindingID;

 1 CREATE PROCEDURE [base].[Binding#Insert](@json nvarchar(max), @id int out)
 2 WITH ENCRYPTION
 3 AS
 4 BEGIN
 5 ...
 6 
 7         declare    @name nvarchar(100);
 8         select    @name=Binding from openjson(@json, '$') with (Binding nvarchar(100))
 9 
10         -- insert Binding
11         insert    base._Binding(Name)select @name
12         where    not exists(select 1 from base._Binding p where p.Name=@name);
13 
14         select    @id=ID from base.Binding#Raw() where Name=@name;
15 
16 ...
17 END

 

继续,插入Book信息;

继续,插入BookInfo的信息;

继续,插入BookNbr信息;

继续,插入BookSupplement信息;

继续,插入BookTag信息;

 1 CREATE PROCEDURE [base].[BookTag#Insert](@json nvarchar(max), @bookID bigint)
 2 WITH ENCRYPTION
 3 AS
 4 BEGIN
 5 ...
 6 
 7         -- insert Tag
 8         insert    base._Tag(Name)select value
 9         from    openjson(@json, '$.Tags') x
10         where    not exists(select 1 from base._Tag p where p.Name=x.value);
11 
12         insert    base._BookTag(BookID, TagID) select @bookID, x.ID
13         from    openjson(@json, '$.Tags') j join base.Tag#Raw() x on x.Name=j.value
14 
15 ...
16 END

 

继续,插入BookAuthor信息;

 1 CREATE PROCEDURE [base].[BookAuthor#Insert](@json nvarchar(max), @bookID bigint)
 2 WITH ENCRYPTION
 3 AS
 4 BEGIN
 5 ...
 6 
 7         -- insert Author
 8         insert    base._Author(Name)select value
 9         from    openjson(@json, '$.Authors') x
10         where    not exists(select 1 from base._Author p where p.Name=x.value);
11 
12         insert    base._BookAuthor(BookID, AuthorID) select @bookID, x.ID
13         from    openjson(@json, '$.Authors') j join base.Author#Raw() x on x.Name=j.value
14 
15 ...
16 END

 

继续,插入BookTranslator信息;

 1 CREATE PROCEDURE [base].[BookTranslator#Insert](@json nvarchar(max), @bookID bigint)
 2 WITH ENCRYPTION
 3 AS
 4 BEGIN
 5 ...
 6 
 7         -- insert Translator
 8         insert    base._Author(Name)select value
 9         from    openjson(@json, '$.Translators') x
10         where    not exists(select 1 from base._Author p where p.Name=x.value);
11 
12         insert    base._BookTranslator(BookID, TranslatorID) select @bookID, x.ID
13         from    openjson(@json, '$.Translators') j join base.Author#Raw() x on x.Name=j.value
14 
15 ...
16 END

 

最后,关联新增的Book信息和Shelf,插入ShelfBook信息。

 

现在放出Init Script

Book_Init.sql

 1 CREATE PROCEDURE [svc].[Book$Init](@json nvarchar(max))
 2 WITH ENCRYPTION
 3 AS
 4 BEGIN
 5 ...
 6 
 7         declare    @stringID varchar(36), @userID int,  @shelfID int;
 8         select    @stringID=u.StringID,  @userID=u.ID, @shelfID=s.ID
 9         from    openjson (@json, '$') with (StringID varchar(36))
10         cross    apply core.User#For(StringID) u
11         join    core.Party#Raw() s on s.PID=u.ID;
12 
13         declare    @stateID int=(select BookCreated from core.Status#ID());
14 
15         -- init Matter
16         insert    core._Matter(Type, UserID, StateID)
17         select    k._Book, @userID, @stateID from core.Matter#Type() k;
18         declare    @matterID int=@@identity;
19 
20         -- init FileBank
21         insert    base._FileBank(Type, Url)
22         select    k._BookImage, ImageUrl
23         from    openjson(@json, '$') with (ImageUrl varchar(200))
24         cross    apply base.FileBank#Type() k;
25         declare    @imageID int=@@identity;
26         
27         -- insert Publisher
28         declare    @publisherID int;
29         exec    base.Publisher#Insert @json=@json, @id=@publisherID out;
30         
31         -- insert Binding
32         declare    @bindingID int;
33         exec    base.Binding#Insert @json=@json, @id=@bindingID out;
34 
35         -- insert Book
36         insert    base._Book(ID, Title, PublisherID, BindingID, ImageID)
37         select    @matterID, Title, @publisherID, @bindingID, @imageID
38         from    openjson(@json, '$') with (Title nvarchar(100));
39         
40         -- insert BookInfo
41         insert    base._BookInfo(ID, OriginTitle, PageCnt, Pubdate, SubTitle)
42         select    @matterID, OriginTitle, Pages, Pubdate, SubTitle
43         from    openjson(@json, '$')
44         with (
45             Pages       int, 
46             Pubdate     char(10), 
47             SubTitle    nvarchar(150), 
48             OriginTitle nvarchar(150)
49         );
50         
51         -- insert BookNbr
52         insert    base._BookNbr(ID, Type, Number)
53         select    @matterID, k._ISBN13, Isbn13
54         from    base.BookNbr#Type() k, openjson(@json, '$') with (Isbn13 char(13));
55         
56         insert    base._BookNbr(ID, Type, Number)
57         select    @matterID, k._ISBN10, Isbn10
58         from    base.BookNbr#Type() k, openjson(@json, '$') with (Isbn10 char(10));
59         
60         -- insert BookSupplement
61         insert    base._BookSupplement(ID, Type, Supplement)
62         select    @matterID, k._AuthorIntro, AuthorIntro
63         from    base.BookSupplement#Type() k, openjson(@json, '$') with (AuthorIntro nvarchar(max));
64         
65         insert    base._BookSupplement(ID, Type, Supplement)
66         select    @matterID, k._Summary, Summary
67         from    base.BookSupplement#Type() k, openjson(@json, '$') with (Summary nvarchar(max));
68

71         from    base.BookSupplement#Type() k, openjson(@json, '$') with (Catalog nvarchar(max));
72 
73         -- insert BookTag
74         exec    base.BookTag#Insert @json=@json, @bookID=@matterID;

好了,开始测试。

...

查询DB,看看有没有数据进DB:

开户送38体验金不限id 1

开户送38体验金不限id 2

 

 截图中展示了部分查询结果,基本没什么问题了。

下面要做的是展示Shelf中的Book信息,要等今天活干完才能继续写了。
