下面是程序。即使我已将@startdate 转换为varchar，我仍不断收到SQL 必须声明标量变量“@sql”。我错过了什么？ 

CREATE PROCEDURE [dbo].[project_revenue_forecast_monthly]
@startDate datetime,
@sql varchar(max)
AS

SET @sql = 'SELECT CLIENTNAME, PROJECTNAME, PROJECTSD, 
    isnull([' + REPLACE(SUBSTRING(CONVERT(varchar, @startDate, 13), 4, 8), ' ', '') + '],0) as
      [' + REPLACE(SUBSTRING(CONVERT(varchar, @startDate, 13), 4, 8), ' ', '') + '], 
    isnull([' + REPLACE(SUBSTRING(CONVERT(varchar, DATEADD(MONTH, 1, @startDate), 13), 4, 8), ' ', '') + '],0) as  
      [' + REPLACE(SUBSTRING(CONVERT(varchar, DATEADD(MONTH, 1, @startDate), 13), 4, 8), ' ', '') + '],
    isnull([' + REPLACE(SUBSTRING(CONVERT(varchar, DATEADD(MONTH, 2, @startDate), 13), 4, 8), ' ', '') + '],0) as  
      [' + REPLACE(SUBSTRING(CONVERT(varchar, DATEADD(MONTH, 2, @startDate), 13), 4, 8), ' ', '') + '],
    isnull([' + REPLACE(SUBSTRING(CONVERT(varchar, DATEADD(MONTH, 3, @startDate), 13), 4, 8), ' ', '') + '],0) as  
      [' + REPLACE(SUBSTRING(CONVERT(varchar, DATEADD(MONTH, 3, @startDate), 13), 4, 8), ' ', '') + '],
    isnull([' + REPLACE(SUBSTRING(CONVERT(varchar, DATEADD(MONTH, 4, @startDate), 13), 4, 8), ' ', '') + '],0) as  
      [' + REPLACE(SUBSTRING(CONVERT(varchar, DATEADD(MONTH, 4, @startDate), 13), 4, 8), ' ', '') + '],
    isnull([' + REPLACE(SUBSTRING(CONVERT(varchar, DATEADD(MONTH, 5, @startDate),  13), 4, 8), ' ', '') + '],0) as  
      [' + REPLACE(SUBSTRING(CONVERT(varchar, DATEADD(MONTH, 5, @startDate), 13), 4, 8), ' ', '') + '],

    FROM
      (

这样做，请注意，如果你不想@Startdate离开，你也应该改变它的位置。

CREATE PROCEDURE [dbo].[project_revenue_forecast_monthly]
@startDate datetime,

AS

Declare @sql varchar(max)
