Question

我有一个很长的查询，可以检索一长串物品，要实现这一点，我需要动态地进行查询：

相关代码：

DECLARE @Sql NVARCHAR(MAX) = '
  DECLARE @DList TABLE
            (
                            [ProjectKey]         INT
                           , [DesignKey]          INT
                          ...
            )

            DECLARE @ExistDesignKey BIT = (SELECT TOP 1
                               1
                               FROM [#SearchKeys]);

                                   INSERT INTO @DList
                 SELECT
                       [p].[ProjectKey]
                     , [pd].[DesignKey]
                     ...

                WHERE ...

   ';


            DECLARE @Select NVARCHAR(MAX) = ' SELECT
                    *
                    FROM @DList
               ORDER BY
                    '+@CurrentSortBy+'
                    , [Design Name]
                    , [DesignTypeName]
                    , [DesignNumber]
                    , [RevisionNumber]
                            ';
            DECLARE @Query NVARCHAR(MAX) = @Sql + @Select

因此，如您所见，我创建具有多列的表，然后将数据插入其中。

我要做的是在此表中添加另外两列，但是我需要使用DesignKey列行进行查询。

新列：

DECLARE @CustomerAndContactsTable AS TABLE
(
                                   [CustomerName]         VARCHAR(1000)
                                 , [ContactName]          VARCHAR(1000)
                                 , [CommunicationType]    VARCHAR(255)
                                 , [CommunicationAddress] VARCHAR(1000)
)

INSERT INTO @CustomerAndContactsTable
      SELECT
            [CU].[Name]
          , CONCAT([C].[FirstName] , ' ' , [C].[LastName])
          , [CT].[DeviceType]
          , [COM].[Address]
            FROM [DesignCustomer] AS [DC]
                INNER JOIN [Customer] AS [CU] ON [DC].[CustomerKey] = [CU].[CustomerKey]
                INNER JOIN [CustomerContact] AS [CC] ON [DC].[CustomerKey] = [CC].[CustomerKey]
                INNER JOIN [Contact] AS [C] ON [CC].[ContactKey] = [C].[ContactKey]
                INNER JOIN [Communication] AS [COM] ON [c].[ContactGuid] = [com].[ComGuid]
                INNER JOIN [ComType] AS [CT] ON [COM].[ComTypeKey] = [CT].[ComTypeKey]
            WHERE [DesignKey] =  --need designkey of row 
                AND [c].[IsPrincipal] = 1
                AND [COM].[ComTypeKey] IN(1 , 2 , 3 , 4)
                AND [DC].[Contracted] = 1

SELECT TOP 1
      [CustomerName]
    , CONCAT([ContactName] , ' Contact: ' , STUFF(
      (SELECT
            ', '+CONCAT([CommunicationType] , ': ' , [CommunicationAddress])
            FROM @CustomerAndContactsTable FOR XML PATH('')
      ) , 1 , 1 , '')) AS [PrincipalContact]
      FROM @CustomerAndContactsTable
      GROUP BY
             [CustomerName]
            , [ContactName]
            , [CommunicationType]
            , [CommunicationAddress]

我想将这两列设置为CustomerName和PrincipalContact，但是如您所见，我需要在@ designkey表中使用CustomerAndContactsTable

一旦具有DList值并用于插入另外两列，该如何迭代@@ DesignKey？

在填充表之后创建列
