使用存储过程批量插入 [英] Bulk insert using stored procedure

问题描述

我有一个运行良好的查询：

I have a query which is working fine:

BULK INSERT ZIPCodes 
FROM  'e:\5-digit Commercial.csv' 
WITH 
( 
     FIRSTROW = 2 ,
    FIELDTERMINATOR = ',', 
    ROWTERMINATOR = '\n' 
)

但是现在我想为其创建存储过程。

but now I want to create a stored procedure for it.

我已经编写了以下代码以使其成为存储过程：

I have written below code to make its stored procedure:

create proc dbo.InsertZipCode
@filepath varchar(500)='e:\5-digit Commercial.csv'
as
begin
BULK INSERT ZIPCodes 
FROM  @filepath 
WITH 
( 
     FIRSTROW = 2 ,
    FIELDTERMINATOR = ',', 
    ROWTERMINATOR = '\n' 
)
end

，但显示错误：

消息102 ，级别15，状态1，过程
InsertZipCode，第6行错误语法
在'@filepath'附近。

Msg 102, Level 15, State 1, Procedure InsertZipCode, Line 6 Incorrect syntax near '@filepath'.

消息319，级别15，状态1，过程
InsertZipCode，第7行关键字 with附近的语法
不正确。如果此
语句是公用表
表达式，xmlnamespaces子句或
a更改跟踪上下文子句，则必须用分号将
前面的语句终止于
。

Msg 319, Level 15, State 1, Procedure InsertZipCode, Line 7 Incorrect syntax near the keyword 'with'. If this statement is a common table expression, an xmlnamespaces clause or a change tracking context clause, the previous statement must be terminated with a semicolon.

请告诉我我做错了什么，我可以做些什么才能使其在存储过程中正常工作。

Please tell me what I am doing wrong and what I can do to make it work in stored procedure.

谢谢

推荐答案

您的存储过程代码没有问题-关键是：批量插入命令不能接受文件名作为变量。

There's nothing wrong with your stored procedure code - the point is: the BULK INSERT command cannot accept a file name as a variable.

这确实有效：

BULK INSERT ZIPCodes 
FROM  'e:\5-digit Commercial.csv' 
WITH 

，但这在存储过程中是否有效：

but this never works - within a stored proc or not:

DECLARE @filename VARCHAR(255)
SET @filename = 'e:\5-digit Commercial.csv' 

BULK INSERT ZIPCodes 
FROM @filename
WITH 

所以你做不到不幸的是，这种方式。您可以考虑将 BULK INSERT 语句构建为字符串（具有固定文件名），然后将其作为动态SQL执行-但是我看不到任何其他解决方案

So you just cannot do it this way, unfortunately. You could consider building up your BULK INSERT statement as a string (with a fixed file name) and then execute it as dynamic SQL - but I don't really see any other solution.

DECLARE @filepath nvarchar(500)
SET @filepath = N'e:\5-digit Commercial.csv'

DECLARE @bulkinsert NVARCHAR(2000)

SET @bulkinsert = 
       N'BULK INSERT ZIPCodes FROM ''' + 
       @filepath + 
       N''' WITH (FIRSTROW = 2, FIELDTERMINATOR = '','', ROWTERMINATOR = ''\n'')'

EXEC sp_executesql @bulkinsert
