執行多個存儲過程導致錯誤[使用事務處理]

Question

SQL Server Management Studio中發生了一些非常奇怪的事情。

我創建了一個存儲過程，然後在每次調用時使用不同的參數執行此存儲過程（在一行中）。

然後我得到一個錯誤，就像我試圖在表中使用相同的主鍵插入一個值，這不應該發生，因爲我有一個條件，試圖避免這一點。

此外，我有存儲過程內的每個代碼塊內的交易。

我有一些問題，SQL Server Management Studio如何觸發所有代碼行？它解析並分別運行每一行？在序列中......我想。我猜想在這種情況下，沒有多個線程同時運行多個存儲過程。

我只是選擇4行以上的存儲過程執行並出現錯誤。

我試圖以單一方式執行每個存儲過程調用，並且我沒有收到任何錯誤。那到底是什麼？我想我的代碼是好的，但也許你應該檢查了這一點：

USE mydatabase; 
GO 

IF EXISTS (SELECT * FROM sys.objects 
      WHERE type = 'P' AND OBJECT_ID = OBJECT_ID('[myschema].[CategoriesFields]')) 
    EXEC('DROP PROCEDURE [myschema].[CategoriesFields]') 

IF NOT EXISTS (SELECT * FROM sys.objects 
       WHERE type = 'P' AND OBJECT_ID = OBJECT_ID('[myschema].[CategoriesFields]')) 
    EXEC('CREATE PROCEDURE [myschema].[CategoriesFields] 
     @CategoryParentName NVARCHAR(256), 
     @CategoryName NVARCHAR(256), 
     @FieldCode NVARCHAR(64) 
     AS 
     BEGIN 
     SET NOCOUNT ON; 
     BEGIN TRY 

     BEGIN TRANSACTION [InsertCategoryTrans]; 

     DECLARE @CategoryId int;        

     DECLARE @CategoryParentId int; 
      IF @CategoryParentName IS NOT NULL 
       SELECT @CategoryParentId = Id FROM [mydatabase].[myschema].[Categories] WHERE CategoryName = @CategoryParentName 

      --INSERT CATEGORY 
      IF @CategoryParentId IS NULL 
       IF NOT EXISTS (SELECT * FROM [mydatabase].[myschema].[Categories] WHERE CategoryName = @CategoryName AND CategoryParentId IS NULL) 
         INSERT INTO [mydatabase].[myschema].[Categories] (CategoryName, CategoryParentId) 
         VALUES (@CategoryName, @CategoryParentId) 
      ELSE     
       IF NOT EXISTS (SELECT * FROM [mydatabase].[myschema].[Categories] WHERE CategoryName = @CategoryName AND CategoryParentId = @CategoryParentId)      
         INSERT INTO [mydatabase].[myschema].[Categories] (CategoryName, CategoryParentId) 
          VALUES (@CategoryName, @CategoryParentId)            

      SET @CategoryId = @@IDENTITY; 

      IF @CategoryId IS NULL 
       SELECT @CategoryId = Id FROM [mydatabase].[myschema].[Categories] WHERE CategoryName = @CategoryName 



      IF @FieldCode IS NOT NULL AND NOT EXISTS (SELECT * FROM [mydatabase].[myschema].[Fields] WHERE CategoryId = @CategoryId AND FieldCode = @FieldCode) 
       INSERT INTO [mydatabase].[myschema].[Fields] (CategoryId, FieldCode) 
        VALUES (@CategoryId, @FieldCode)  

     COMMIT TRANSACTION [InsertCategoryTrans]; 
    END TRY 
    BEGIN CATCH 
     ROLLBACK TRANSACTION [InsertCategoryTrans]; 
     SELECT ERROR_MESSAGE() AS [Message], ERROR_LINE() AS [Line] 
    END CATCH 
    END'); 


EXEC [mydatabase].[myschema].[CategoriesFields] NULL, 'CategoryA', 'FieldExample' 
EXEC [mydatabase].[myschema].[CategoriesFields] NULL, 'CategoryA', 'FieldExample2' 

EXEC [mydatabase].[myschema].[CategoriesFields] 'CategoryA', 'Child_CategoryOfA', 'Arruamento'

EXEC [mydatabase].[myschema].[CategoriesFields] 'CategoryC', 'ChildOfC_Category15', 'Field5' 
EXEC [mydatabase].[myschema].[CategoriesFields] 'CategoryC', 'ChildOfC_Category15', NULL 


EXEC [mydatabase].[myschema].[CategoriesFields] 'ChildOfC_Category15', 'ChildOf_ChildOfC_Category15', 'Detail' 
EXEC [mydatabase].[myschema].[CategoriesFields] 'ChildOfC_Category15', 'ChildOf_ChildOfC_Category15', 'AllowedRoles' 
EXEC [mydatabase].[myschema].[CategoriesFields] 'ChildOfC_Category15', 'ChildOf_ChildOfC_Category15', 'RelatedCompanies' 

EXEC [mydatabase].[myschema].[CategoriesFields] 'FieldLabels', 'Company', 'Identifier' 
EXEC [mydatabase].[myschema].[CategoriesFields] 'FieldLabels', 'Company', 'Name' 

EXEC [mydatabase].[myschema].[CategoriesFields] 'Common', 'FieldLabels', 'Identifier' 
EXEC [mydatabase].[myschema].[CategoriesFields] 'Common', 'FieldLabels', 'Code' 
EXEC [mydatabase].[myschema].[CategoriesFields] 'Common', 'FieldLabels', 'Name' 
EXEC [mydatabase].[myschema].[CategoriesFields] 'Common', 'ButtonLabels', 'Code' 
EXEC [mydatabase].[myschema].[CategoriesFields] 'Common', 'Messages', 'Name' 

當多個選擇所有的線路和執行所有我得到的錯誤是：

INSERT語句衝突以FOREIGN KEY約束 「FK_myschema.Fields_myschema.Categories_CategoryId」。衝突 發生在數據庫「mydatabase」，表「myschema.Categories」，列 'Id'。

預先感謝您！

好這個問題是固定的改變，我commiting的交易，以及一個事務不同的事務分離的方式，這裏是產生的代碼，如果有人需要

EXEC('CREATE PROCEDURE [myschema].[CategoriesFields] 
     @CategoryParentName NVARCHAR(256), 
     @CategoryName NVARCHAR(256), 
     @FieldCode NVARCHAR(64) 
     AS 
     BEGIN 
     SET NOCOUNT ON; 
     BEGIN TRY 

     BEGIN TRANSACTION [InsertCategoryTrans]; 

     DECLARE @CategoryId int;        

     DECLARE @CategoryParentId int; 
      IF @CategoryParentName IS NOT NULL 
       SELECT @CategoryParentId = Id FROM [mydatabase].[myschema].[Categories] WHERE CategoryName = @CategoryParentName 

      --INSERT CATEGORY 
      IF @CategoryParentId IS NULL 
      BEGIN 
       IF NOT EXISTS (SELECT * FROM [mydatabase].[myschema].[Categories] WHERE CategoryName = @CategoryName AND CategoryParentId IS NULL) 
         INSERT INTO [mydatabase].[myschema].[Categories] (CategoryName, CategoryParentId) 
         VALUES (@CategoryName, @CategoryParentId) 
      END 
      ELSE 
      BEGIN     
       IF NOT EXISTS (SELECT * FROM [mydatabase].[myschema].[Categories] WHERE CategoryName = @CategoryName AND CategoryParentId = @CategoryParentId)      
         INSERT INTO [mydatabase].[myschema].[Categories] (CategoryName, CategoryParentId) 
          VALUES (@CategoryName, @CategoryParentId)            
      END 

      SET @CategoryId = @@IDENTITY; 

      IF @CategoryId IS NULL 
       SELECT @CategoryId = Id FROM [mydatabase].[myschema].[Categories] WHERE CategoryName = @CategoryName 

      COMMIT TRANSACTION [InsertCategoryTrans]; 

      IF @FieldCode IS NOT NULL AND NOT EXISTS (SELECT * FROM [mydatabase].[myschema].[Fields] WHERE CategoryId = @CategoryId AND FieldCode = @FieldCode) 
      BEGIN 
       BEGIN TRANSACTION [InsertCategoryFieldTrans]; 
        INSERT INTO [mydatabase].[myschema].[Fields] (CategoryId, FieldCode) 
        VALUES (@CategoryId, @FieldCode)  
       COMMIT TRANSACTION [InsertCategoryFieldTrans]; 
      END 

    END TRY 
    BEGIN CATCH 
     ROLLBACK TRANSACTION [InsertCategoryTrans]; 
     SELECT ERROR_MESSAGE() AS [Message], ERROR_LINE() AS [Line]
