将参数传递给存储过程时出错

Question

我有以下存储过程：

SET QUOTED_IDENTIFIER OFF;
GO
ALTER PROCEDURE [transactiondb] @dbname1 NVARCHAR(128)
AS
    DECLARE @query VARCHAR(1000);
    SET @query = "SELECT TOP 10*
    FROM @dbname1.dbo.transaction";
    EXEC (@query);
GO

当我执行存储过程时出现以下错误：

Must declare the scalar variable "@dbname1"

我很确定这与传递变量的方式有关，但我真的很难理解发生了什么或如何纠正？

Answer 1

试试这个。它对我有用，

Alter PROCEDURE [transactiondb] @dbname1 NVARCHAR(128)
AS
    DECLARE @query VARCHAR(1000);
    SET @query = 'SELECT TOP 10 *
    FROM ' +@dbname1+'.dbo.transaction';
    EXEC (@query);
Go
