sp_executesql的语法问题

Question

我试图编写一个存储过程并且我一直收到这个错误，我没有定义@address，我做了。我知道我错过了一件小事，我该如何改变呢？

CREATE PROCEDURE search_domaintable
@link nvarchar(50),
@address nvarchar(50)
AS
EXEC ('SELECT rank , ip FROM dbo.['+@link+'] where [address]=@address ');

我也试过这个：

CREATE PROCEDURE search_domaintable
@link nvarchar(50),
@address nvarchar(50)
AS
EXEC ('SELECT rank , ip FROM dbo.['+@link+'] where [address]=['+@address+']');

但它需要@address值作为列名并告诉我这样的列不存在。

存储过程应该是这样的：

CREATE PROCEDURE search_domaintable
@link nvarchar(50),
@address nvarchar(50)
AS
EXEC ('SELECT rank , ip FROM dbo.['+@link+'] where address  = ''' + @address + '''');
