我有一个要用于动态存储过程的表，
--Creating table
DECLARE @SearchKeys AS TABLE(
DesignKey INT
)
--Filling table
SELECT pd.DesignKey FROM [Project] AS [p]
LEFT JOIN [ProjectDesign] AS [pd] ON [p].[ProjectKey] = [pd].[ProjectKey]
LEFT JOIN [Design] AS [d] ON [pd].[DesignKey] = [d].[DesignKey]
INNER JOIN [DesignType] AS [DE] ON [D].
WHERE JN.Note LIKE '%'+@JobNote+'%'
GROUP BY ParentGuid) JN ON P.ProjectGuid = JN.ParentGuid
现在我的桌子上有多个DesignKeys
现在在我的动态查询中，我想对该表进行内部联接，如下所示：
DECLARE @Sql NVARCHAR(MAX) = '
DECLARE @DList TABLE
(
[ProjectKey] INT
, [Project Name] NVARCHAR(255)
...
)
INSERT INTO @DList
SELECT
[p].[ProjectKey]
, [p].[Name] AS [Project Name]
....
FROM [Project] AS [p]
INNER JOIN '+@SearchKeys+' AS [SK] ON [D].[DesignKey] = [SK].[DesignKey]
但是@SearchKeys变量用红色标记并抛出
必须声明标量变量“ @SearchKeys”
但是我已经在查询中声明了它。我在做什么错了？

表变量未在exec中继承。但是，临时表是。所以我建议：
CREATE TABLE #SearchKeys (
DesignKey INT
);
. . .
DECLARE @Sql NVARCHAR(MAX) = '
DECLARE @DList TABLE (
[ProjectKey] INT,
[Project Name] NVARCHAR(255)
...
);
INSERT INTO @DList ( . . . )
SELECT [p].[ProjectKey], [p].[Name] AS [Project Name], ....
FROM [Project] [p] JOIN
#SearchKeys [SK]
ON [D].[DesignKey] = [SK].[DesignKey]
'
