Question

我对此代码有疑问：

ALTER PROCEDURE [arch].[spInsertToDocumentFileCategoryRelation]
        @DocumentNumber nvarchar(50)
       ,@DocumentDate date
       ,@IsDocumentDelete bit
       ,@Address nvarchar(max)
       ,@DocumentLevelTypeId int

       ,@DocumentId2 bigint
       ,@DocumentRelationTypeId tinyint

       ,@CategoryId bigint 
       ,@FileId bigint

       ,@FileAssignCategoryId bigint OUTPUT
       ,@DocumentRelationId bigint OUTPUT
       ,@FileOfDocumentId bigint OUTPUT
       ,@DocumentId bigint OUTPUT

AS
BEGIN

    INSERT INTO [arch].[Document]
       (
        [DocumentNumber]
       ,[DocumentDate]
       ,[DateOfDocumentCreate]
       ,[IsDocumentDelete]
       ,[Address]
       ,[DocumentLevelTypeId]
       )
    VALUES
       (
        @DocumentNumber
       ,@DocumentDate
       ,'2015-5-12'
       ,@IsDocumentDelete
       ,@Address
       ,@DocumentLevelTypeId
       )

       Set @DocumentId = SCOPE_IDENTITY();

       INSERT INTO [arch].[FileOfDocument]
       (
       [DocumentId]
       ,[FileId]
       )
    VALUES
       (
       @DocumentId
       ,@FileId
       )

       Set @FileOFDocumentId = SCOPE_IDENTITY();

       INSERT INTO [arch].[DocumentRelation]
       (
        [DocumentRelationTypeId]
        ,[DocumentId1]
        ,[DocumentId2]

       )
    VALUES
       (
        @DocumentRelationTypeId
       ,@DocumentId
       ,@DocumentId2
       )

       Set @DocumentRelationId = SCOPE_IDENTITY();

       INSERT INTO [arch].[FileAssignCategory]
       (
        [CategoryId]
       ,[FileId]
       )
    VALUES
       (
        @CategoryId
       ,@FileId
       )

       Set @FileAssignCategoryId = SCOPE_IDENTITY();
END

这段代码执行正确但是当我想用一些输入值测试这个存储过程时，sql server报告了一些错误：

Msg 515, Level 16, State 2, Procedure     
spInsertToDocumentFileCategoryRelation, Line 27
Cannot insert the value NULL into column 'DocumentTypeId', table    
'ffisherDB.arch.Document'; column does not allow nulls. INSERT fails.

The statement has been terminated.

我有四个用SCOPE_IDENTITY（）设置的Key。第一个设置完全正确，但其他设置失败并且错误报告上方。

请帮帮我。

Answer 1

好吧，从错误文本看，您的arch.Document表格似乎有不可为空的列DocumentTypeId。

你在这里没有填写这个专栏：

INSERT INTO [arch].[Document]
   (
    [DocumentNumber]
   ,[DocumentDate]
   ,[DateOfDocumentCreate]
   ,[IsDocumentDelete]
   ,[Address]
   ,[DocumentLevelTypeId]
   )

所以这个列有它的默认值（我猜它是null），因此这个插入失败，因此@DocumentId为空，剩下的插入也失败...

Answer 2

根据DocumentTypeId表中的第一条错误消息Document字段不允许为空。您应该在插入查询中插入一个值。

将插入内容更改为

INSERT INTO [arch].[Document]
       (
        [DocumentNumber]
       ,[DocumentDate]
       ,[DateOfDocumentCreate]
       ,[IsDocumentDelete]
       ,[Address]
       ,[DocumentLevelTypeId]
       ,[DocumentTypeId]  --Add document type id here
       )
    VALUES
       (
        @DocumentNumber
       ,@DocumentDate
       ,'2015-5-12'      --You better insert a DATE type or in ISO formatted 'yyyymmdd' string. 
       ,@IsDocumentDelete
       ,@Address
       ,@DocumentLevelTypeId
       ,@DocumentTypeId  --Insert a non - null value 
       )

第二＆amp;第三条错误消息是由于第一次错误造成的。
