Question

我有一个Project表，其中包含Poject Start和Project End日期。我需要将列作为Quarters添加到新表Planned Cost中，Quarters应该在Project Start和End Dates之间。

已经编写了一个程序，根据我们传递的参数动态添加列 - 项目和业务名称。但是代码没有工作并且给出了错误。

代码：

CREATE PROCEDURE ****
@Project_Name NVARCHAR(100) output, 
@Business NVARCHAR(100) output 
AS 
SET nocount ON 

    DECLARE @column NVARCHAR(20), 
            @SQL    NVARCHAR(1000) 
    DECLARE @ParamDefinition AS NVARCHAR(2000) 

    SET @column = N'select Q +cast(FLOOR(((12 + MONTH(Engagement_Master_FPA.[planned start date])) % 12) / 3 ) + 1  as varchar(4))+_+CAST(year(Engagement_Master_FPA.[planned start date]) AS varchar(4)) + from Engagement_Master_FPA where Engagement_Master_FPA.project=' 
                  + @Project_Name + ' and Business=' + @Business 
    SET @SQL = N'ALTER TABLE [[Planned_Cost_Master_FPA_BKP] ADD ' + @column + ' varchar(50)' 
    SET @ParamDefinition=N'@Project_Name nvarchar(100) ,@Business nvarchar(100)' 

    EXECUTE Sp_executesql 
      @SQL, 
      @ParamDefinition, 
      @Project_Name output, 
      @Business output 

    SELECT @Project_Name, 
           @Business

错误：

Msg 156, Level 15, State 1, Line 5
Incorrect syntax near the keyword 'select'.
Msg 102, Level 15, State 1, Line 5
Incorrect syntax near 'varchar'.
