我正在使用以下 SP：
ALTER PROCEDURE [dbo].[FullExport]
(
@db_name as nvarchar(100),
@table_name varchar(100),
@file_name varchar(100)
)
as
Begin
//Generate column names as a recordset
DECLARE @columns varchar(8000), @sql varchar(8000), @data_file varchar(100)
SELECT @columns=coalesce(@columns+',','')+column_name+' as '+column_name
FROM information_schema.columns
WHERE table_name=@table_name
SELECT @columns=''''''+replace(replace(@columns,' as ',''''' as '),',',',''''')
//Create a dummy file to have actual data
SELECT @data_file = substring(@file_name,1,len(@file_name)-
charindex('\',reverse(@file_name)))+'\data_file.xls'
//Generate column names in the passed EXCEL file
SET @sql='exec master..xp_cmdshell ''bcp " SELECT * FROM
(SELECT '+ @columns+') as t" queryout "'+@file_name+'" -c'''
exec(@sql)
//Generate data in the dummy file
SET @sql='exec master..xp_cmdshell ''bcp "SELECT * from '+@db_name+'..'
+@table_name+'" queryout "'+@data_file+'" -c'''
exec(@sql)
//Copy dummy file to passed EXCEL file
SET @sql= 'exec master..xp_cmdshell ''type '+@data_file+' >> "' +
@file_name+'"'''
exec(@sql)
//Delete dummy file
SET @sql= 'exec master..xp_cmdshell ''del '+@data_file+''''
exec(@sql)
结尾
正在创建文件，但内容为空，有什么想法吗？
