如何使用 Table 值作为参数 运行 存储过程

Question

我有一个用于将数据插入 table 的存储过程，它有 6 个参数

SP:

CREATE PROCEDURE [dbo].[sp_tb_mis_am_node]
@pid_code varchar(10),
@id_code varchar(10),
@description varchar(50),
@disp_order int, /*** This will serve as a display order sequence ***/
@username varchar(20),
@user_key int,

现在我想 运行 这个 SP 并使用我现有 table 中的值填充它的参数，并使用与列

相同的编号和名称

Table:

SELECT  [pid_code]
      ,[id_code]
      ,[description]
      ,[disp_order]
      ,[username]
      ,[user_key]
  FROM [webloan_helper].[dbo].[tbl_ledger_add]

我将如何执行它？

我正在使用 Microsoft SQL Server 2008 R2

创建过程ExecuteProc 作为 开始 声明@RowNumber INT； -- 行数 Table webloan_helper SET @RowNumber = 1;

While (@RowNumber <= (SELECT COUNT(*) FROM webloan_helper))
Begin
    Declare @pid_code varchar(10);
    Declare @id_code varchar(10);
    Declare @description varchar(50);
    Declare @disp_order int;
    Declare @username varchar(20);
    Declare @user_key int;

    Set @pid_code = (Select pid_code From (Select Row_Number() Over (Order By pid_code) As RowNum, * From webloan_helper) t2 Where RowNum = @RowNumber);
    Set @id_code = (Select id_code From (Select Row_Number() Over (Order By pid_code) As RowNum, * From webloan_helper) t2 Where RowNum = @RowNumber);
    Set @description = (Select [description] From (Select Row_Number() Over (Order By pid_code) As RowNum, * From webloan_helper) t2 Where RowNum = @RowNumber);
    Set @disp_order = (Select disp_order From (Select Row_Number() Over (Order By pid_code) As RowNum, * From webloan_helper) t2 Where RowNum = @RowNumber);
    Set @username = (Select username From (Select Row_Number() Over (Order By pid_code) As RowNum, * From webloan_helper) t2 Where RowNum = @RowNumber);
    Set @user_key = (Select user_key From (Select Row_Number() Over (Order By pid_code) As RowNum, * From webloan_helper) t2 Where RowNum = @RowNumber);

    Exec sp_tb_mis_am_node @pid_code,@id_code,@description,@disp_order,@username,@user_key;
     -- Order By Should be unique column

SET @RowNumber= @RowNumber+ 1; 结束

结束

如果重写您的存储过程^1,2 不在卡片上，也不会将正文合并到您当前的方法中²，那么你唯一真正的选择就是循环。

要循环，您可以使用 cursor 和 WHILE，例如：

DECLARE @pid_code varchar(10)
DECLARE @id_code varchar(10)
DECLARE @description varchar(50)
DECLARE @disp_order int
DECLARE @username varchar(20)
DECLARE @user_key int

DECLARE boris cursor local fast_forward FOR SELECT  [pid_code]
      ,[id_code]
      ,[description]
      ,[disp_order]
      ,[username]
      ,[user_key]
  FROM [webloan_helper].[dbo].[tbl_ledger_add]

OPEN boris
FETCH NEXT FROM boris INTO @pid_code,@id_code,@description,
                           @disp_order,@username,@user_key

WHILE @@FETCH_STATUS = 0
BEGIN
    EXEC [sp_tb_mis_am_node] @pid_code,@id_code,@description,
                           @disp_order,@username,@user_key

    FETCH NEXT FROM boris INTO @pid_code,@id_code,@description,
                           @disp_order,@username,@user_key
END
CLOSE boris
DEALLOCATE boris

¹我将对当前程序进行一点重写 recommend, however:

Avoid the use of the sp_ prefix when naming procedures. This prefix is used by SQL Server to designate system procedures. Using the prefix can cause application code to break if there is a system procedure with the same name.

²在任何一种情况下，您都希望将它们重写为基于集合，而不是使用单行。对于存储过程实例的重写，这将意味着采用 table-valued parameter.
