Question

我们正在将新的SQL Server 2017数据库迁移到Azure。今天，我们以评估模式运行了Microsoft数据迁移助手，以便从SQL Server迁移到Azure SQL数据库。我们正在尝试解决“未解决的对对象的引用”阻止程序项。这不应算作跨数据库查询。该视图在我们的本地实例中运行良好。

在“评估建议”部分下，有以下内容：

{  "CompatibilityLevel": "CompatLevel140",
   "Category": "Compatibility",
   "Severity": "Error",
   "ChangeCategory": "MigrationBlocker",
   "RuleId": "71501",
   "Title": "Unresolved references found",
   "Impact": "One or more objects were found that contain unresolved references, which may block migration to Azure SQL Database.",
   "Recommendation": "Address the unresolved references reported in \"Object details\" section.",
              "MoreInfo": "",
              "ImpactedObjects": See below... }

对于dbo.VW_BUILD_PARAMETERS存储过程，ImpactedObjects下报告了以下问题：

        {
          "Name": "dbo.VW_BUILD_PARAMETERS.IsOutPutParameter",
          "ObjectType": "Computed Column",
          "ImpactDetail": "Computed Column: [dbo].[VW_BUILD_PARAMETERS].[IsOutPutParameter] contains an unresolved reference to an object. Either the object does not exist or the reference is ambiguous because it could refer to any of the following objects: [sys].[objects].[P]::[is_output], [sys].[parameters].[is_output] or [sys].[parameters].[P]::[is_output]. For more details, please see: Line 18, Column 1.",
          "SuggestedFixes": []
        },
        {
          "Name": "dbo.VW_BUILD_PARAMETERS.ObjectName",
          "ObjectType": "Computed Column",
          "ImpactDetail": "Computed Column: [dbo].[VW_BUILD_PARAMETERS].[ObjectName] contains an unresolved reference to an object. Either the object does not exist or the reference is ambiguous because it could refer to any of the following objects: [sys].[objects].[Name], [sys].[objects].[SO]::[Name] or [sys].[parameters].[SO]::[Name]. For more details, please see: Line 5, Column 8.",
          "SuggestedFixes": []
        },
        {
          "Name": "dbo.VW_BUILD_PARAMETERS.ParameterOrder",
          "ObjectType": "Computed Column",
          "ImpactDetail": "Computed Column: [dbo].[VW_BUILD_PARAMETERS].[ParameterOrder] contains an unresolved reference to an object. Either the object does not exist or the reference is ambiguous because it could refer to any of the following objects: [sys].[objects].[P]::[parameter_id], [sys].[parameters].[P]::[parameter_id] or [sys].[parameters].[parameter_id]. For more details, please see: Line 14, Column 1.",
          "SuggestedFixes": []
        },

这是存储过程：

CREATE VIEW [dbo].[VW_BUILD_PARAMETERS]
AS
SELECT SO.Name AS [ObjectName],
  CASE SO.Type_Desc 
    WHEN 'SQL_STORED_PROCEDURE'
    THEN 'Procedure'
    WHEN 'SQL_SCALAR_FUNCTION'
    THEN 'Function'
    WHEN 'SQL_INLINE_TABLE_VALUED_FUNCTION'
    THEN 'Function'
  END AS [ObjectType],
  P.parameter_id AS ParameterOrder,
  REPLACE( P.name, '@','') AS ParameterName,
  UPPER(TYPE_NAME(P.system_type_id)) AS ParameterType,
  CASE 
    WHEN TYPE_NAME(P.user_type_id) = 'varchar' 
    THEN CAST(P.max_length AS INT) 
  END AS MaximumCharacterLength,
  P.is_output AS [IsOutPutParameter]
FROM sys.objects AS SO
INNER JOIN sys.parameters AS P 
   ON SO.OBJECT_ID = P.OBJECT_ID
WHERE SO.type IN ('P','FN','IF')
AND P.parameter_id > 0

我看不到'P.parameter_id AS ParameterOrder'的解决方式：

[sys].[objects].[P]::[parameter_id]-为什么要尝试对sys.objects做P别名？没有sys.objects.parameter_id。

[sys].[parameters].[P]::[parameter_id]-看起来应该像这样

[sys].[parameters].[parameter_id]-为什么它不匹配P别名

从Data Migration Assistant评估报告的未解析的sys.objects引用，以迁移到Azure
