具有局部变量和输入变量的存储过程

Question

我正在尝试创建一个过程，我可以指定 2 个输入变量并具有许多本地过程变量，这些变量将 return SQL 查询结果 table.

这是我为此编写的代码。

CREATE PROCEDURE sp_MS_Field_Mapping( 
    @MS_Table_Name VARCHAR(100), 
    @DCW_No VARCHAR(10)
)
AS

SET NOCOUNT ON;


DECLARE @Rsrc_Mapping varchar(100);
DECLARE @Appt_Types_Rsrc varchar(100);
DECLARE @Appt_Type_Settings varchar(100);

SET @Rsrc_Mapping = 'REF_'+@DCW_No+'_Rsrc_Mapping'
SET @Appt_Types_Rsrc = 'REF_'+@DCW_No+'_Appt_Types_Rsrc'
SET @Appt_Type_Settings = 'REF_'+@DCW_No+'_Appt_Type_Settings'

PRINT @Rsrc_Mapping
PRINT @Appt_Types_Rsrc
PRINT @Appt_Type_Settings

SELECT mst.Main_Bookshelf_Old
    ,mst.Main_Bookshelf_New
    ,mst.Main_Bookshelf_New_Mirror

    ,cmn.Appt_Class
    ,cmn.OOS_Inc
FROM @MS_Table_Name mst
INNER JOIN dbo.REF_DCW_CMN_Appt_Setting_Map cmn
    ON mst.Appt_Type_New = cmn.Appt_Type_Name
LEFT JOIN @Rsrc_Mapping rm
    ON mst.Rsrc_New = rm.Rsrc_Mnemonic
INNER JOIN @Appt_Types_Rsrc atr
    ON mst.Appt_Type_New = atr.Appt_Type_Name
        AND mst.Amb_Loc_New = atr.Amb_Loc
        AND mst.Rsrc_New = atr.Rsrc_Available
INNER JOIN dbo.REF_EUS_Appt_Info eus
    ON mst.Appt_Type_Old = eus.Appt_Type
LEFT JOIN @Appt_Type_Settings ats
    ON mst.Appt_Type_New = ats.Appt_Type_Name
        AND mst.Amb_Loc_New = ats.Amb_Loc
RETURN
GO

但是我遇到了这些错误。我正在声明变量，所以我不明白为什么它说我需要声明它们并且两个是输入变量。

Msg 1087, Level 16, State 1, Procedure sp_MS_Field_Mapping, Line 73
Must declare the table variable "@MS_Table_Name".

Msg 1087, Level 16, State 1, Procedure sp_MS_Field_Mapping, Line 76
Must declare the table variable "@Rsrc_Mapping".

Msg 1087, Level 16, State 1, Procedure sp_MS_Field_Mapping, Line 78
Must declare the table variable "@Appt_Types_Rsrc".

Msg 1087, Level 16, State 1, Procedure sp_MS_Field_Mapping, Line 84
Must declare the table variable "@Appt_Type_Settings".

有人可以帮忙吗？

提前致谢。

您需要使用动态 SQL 以变量中的 table 名称执行。使用下面的代码

CREATE PROCEDURE sp_MS_Field_Mapping( 
@MS_Table_Name VARCHAR(100), 
@DCW_No VARCHAR(10)
)
AS

SET NOCOUNT ON;


DECLARE @Rsrc_Mapping varchar(100);
DECLARE @Appt_Types_Rsrc varchar(100);
DECLARE @Appt_Type_Settings varchar(100);

SET @Rsrc_Mapping = 'REF_'+@DCW_No+'_Rsrc_Mapping'
SET @Appt_Types_Rsrc = 'REF_'+@DCW_No+'_Appt_Types_Rsrc'
SET @Appt_Type_Settings = 'REF_'+@DCW_No+'_Appt_Type_Settings'

PRINT @Rsrc_Mapping
PRINT @Appt_Types_Rsrc
PRINT @Appt_Type_Settings

DECLARE @QRY NVARCHAR(MAX)

SET @QRY ='
