问题描述

如何从 excel 复制/粘贴以下分隔数据(默认用制表符分隔):

declare @t_values   nvarchar(max)   =                   
N'                
NULL    490366  NULL    NULL
NULL    490400  NULL    NULL
NULL    490402  NULL    NULL
483061  490404  10  abc1
NULL    490406  NULL    NULL
9766167 490408  3   abc2'
;

到我的临时表:

CREATE TABLE #insertTable
(   transaction_id int     
   ,user_id        int 
   ,purchase_price decimal(8,2) 
   ,mess           varchar(8)
);

?

注意!不使用OPENROWSET

解决方案INSERT INTO

  1. 询问
  2. 程序
  3. SNIPPET (在这里创建片段的快速方法)

解决方案SELECT INTO

  1. 询问

  2. SNIPPET (在这里创建片段的快速方法)

PS如果你有旧的 SQL Server 版本(数据库兼容性设置在 130 以下),你将需要单独的STRING_SPLIT功能。我推荐以下解决方案

解决方案


请使用以下 PROC:

CREATE PROCEDURE dbo.p_values2insertquery
    @t_name   nvarchar(128),                   -- Destination Table Name + [(column names)]
    @t_values nvarchar(max),                   -- Paste Table Values here (from excel for instance)    
    @dlm      nvarchar(128)   = N'  '          -- Delimiter: HT = HorizontalTab = char(9)
AS
/*  p_values2insertquery
        - converts table values stored in @t_values string (separated by default by @dlm=TAB)
          to queries for insert to  table name defined in @t_name


    INPUT:
        @t_name   nvarchar(128),                   -- Destination Table Name + [(column names)]
        @t_values nvarchar(max),                   -- Paste Table Values here (from excel for instance)    
        @dlm      nvarchar(128)   = N'  '          -- Delimiter: HT = HorizontalTab = char(9)

    -- NB! Script do NOT write any ifo to any table
    -- to perform insert please copy/paste script output and execute            


    EXAMPLE:

        IF OBJECT_ID('tempdb..#insertTable') IS NOT NULL DROP TABLE #insertTable;
        CREATE TABLE #insertTable
        (   transaction_id int

           ,mess           varchar(8)
        );

        declare @t_name     nvarchar(128)   = '#insertTable'    -- Table Name for insert

RETURN 0 

例子:

IF OBJECT_ID('tempdb..#insertTable') IS NOT NULL DROP TABLE #insertTable;
CREATE TABLE #insertTable
(   transaction_id int     
   ,user_id        int 
   ,purchase_price decimal(8,2) 
   ,mess           varchar(8)
);

declare @t_name     nvarchar(128)   = '#insertTable'    -- Table Name for insert
declare @t_values   nvarchar(max)   =                   -- Paste Table Values here (from excel for instance)
N'                
NULL    490366  NULL    NULL
NULL    490400  NULL    NULL
NULL    490402  NULL    NULL
483061  490404  10  abc1
NULL    490406  NULL    NULL
9766167 490408  3   abc2'
;
declare @dlm        nvarchar(128)   = char(9);          -- Delimiter: HT = char(9) = HorizontalTab

exec p_values2insertquery @t_name, @t_values

输出(只需复制/粘贴并执行以执行插入):

insert into #insertTable VALUES(NULL,'490366',NULL,NULL);
insert into #insertTable VALUES(NULL,'490400',NULL,NULL);
insert into #insertTable VALUES(NULL,'490402',NULL,NULL);
insert into #insertTable VALUES('483061','490404','10','abc1');
insert into #insertTable VALUES(NULL,'490406',NULL,NULL);
insert into #insertTable VALUES('9766167','490408','3','abc2');
