Question

我有这个代码

USE [DATABASE]
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO

ALTER PROCEDURE [dbo].[GetDataExcel]

as

DECLARE c CURSOR FOR select  Box, Code , Validity FROM
OPENROWSET('Microsoft.ACE.OLEDB.12.0', 'Excel 12.0;Database=C:\Barcodes.xlsx;HDR=YES',     'SELECT Box, Code , Validity FROM [sheet1$]')
declare @Code as bigint
declare @Box as bigint
declare @Validity as date

begin


open c 

fetch next from c into @Box,@Code,@Validity

WHILE @@FETCH_STATUS = 0
begin

Insert into Cards (Box, BarCode, ValidityDate) select Box, Code , Validity FROM     OPENROWSET('Microsoft.ACE.OLEDB.12.0', 'Excel 12.0;Database=C:\Barcodes.xlsx;HDR=YES',     'SELECT Box, Code , Validity FROM [sheet1$]')
fetch next from c into @Box,@Code,@Validity

end

CLOSE c
DEALLOCATE c


end

导出到表“Cards”时，空行也会被复制到表中，并且进程不会停止，循环会一直打开并且一遍又一遍地重新启动进程，查询不会停止执行除非我停止它，当我看到表的内容时，我看到空行的NULL值和填充的行的值，并且它们被重复，所以如何停止查询读取空行并阻止它读取excel文件一遍又一遍？

Answer 1

试试这个循环：

WHILE @@FETCH_STATUS = 0
begin

Insert into Cards (Box, BarCode, ValidityDate)
    select @Box, @Code , @Validity;

fetch next from c into @Box,@Code,@Validity

end;

您的原始代码同时使用游标并直接在from语句中获取。这个版本只使用光标。

Answer 2

为什么不使用这样的东西而不是光标

INSERT INTO (Box, BarCode, ValidityDate) 
SELECT *
  FROM OPENROWSET('Microsoft.ACE.OLEDB.12.0', 'Excel 12.0;Database=C:\Barcodes.xlsx;HDR=YES', 
           'SELECT Box, Code, Validity FROM [sheet1$]')

Answer 3

我使用了Task - ＆gt; Import data选项将数据从excel传输到sql，并且获得了无限循环。我关闭了SQL Server管理工作室并重试了相同的选项，它对我有用。
