解析SQLServer获取Excel中所有Sheet的方法

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
