SQLServer获取Excel中所有Sheet
E盘根目录新建一个Excel文件aa.xls后测试如下代码
use tempdb
go
if (object_id ('udf_getExcelTableNames' ) is not null )
drop function dbo .udf_getExcelTableNames
go
create function udf_getExcelTableNames (@filename varchar (1000 ))
returns @t table (id int , name varchar (255 ))
as
begin
declare
@error int , @obj int , @c int , @sheetname varchar (255 ) , @sheetstring varchar (255 )
exec @error = sp_oacreate 'Excel.Application' , @obj out
exec @error = sp_oamethod @obj , 'Workbooks.Open' , @c out , @filename
exec @error = sp_oagetproperty @obj , 'ActiveWorkbook.Sheets.Count' , @c out
while (@c > 0 )
begin
set @sheetstring = 'ActiveWorkbook.Sheets(' + ltrim (@c )+ ').Name'
exec @error = sp_oagetproperty @obj , @sheetstring , @sheetname out
insert into @t select @c , @sheetname
set @c = @c - 1
end
exec @error = sp_oadestroy @obj
return
end
go
select * from dbo .udf_getExcelTableNames ('e:\aa.xls' )
/*--测试结果
3 Sheet3
2 Sheet2
1 Sheet1

如果文件很多，建议还是用程序倒入了
if (object_id ('t_bulkResult' ) is not null )
drop table t_bulkResult ......
