create procedure sp_expexcle --匯出excel檔案

asdeclare @str as varchar(8000)

set @msg = '成功匯出'+cast(@ncount as varchar(30) )+'條資料。' --匯出後,顯示在匯出excel按鈕的旁邊
print @msg
go總結：
1)將int 轉換為 varchar :cast(@ncount as varchar(30) )
2)定義varchar: declare @str as varchar(8000)
int :declare @count as int
3)賦值:set @mg='aa,bb,ccc'
4)條件下：while @i>=1
begin
i++end
5)列印輸出:print @str1 .這個顯示在訊息裡面，如果select @str1顯示在結果裡面
6)擷取字串:set @mg=substring(@mg,@i+1,len(@mg)-@i)
7)以特定字元分割得到特定字串的位置 set @i=charindex(',',@mg)
8）得到字串長度:set @strlen=len(@str)
9)定義儲存過程引數：
create procedure sp_expexcle
@itemid int=0,
@path varchar(512)='',
@msg varchar(512)='' output
（兩個為輸入引數，乙個為輸出引數）
定義兩個輸入引數，沒有輸出引數則：
create procedure sp_expexcle
@itemid int=0,
@path varchar(512)=''
定義輸出引數為
create procedure sp_expexcle
@msg varchar(512)='' output
10）呼叫儲存過程
exec sp_expexcle 15,'c:\users\administrator\desktop\dkj\匯出資料\12.xls',''
exec sp_expexcle 15,'c:\users\administrator\desktop\dkj\匯出資料\12.xls'
declare @msg
exec sp_expexcle @msg output
select @msg
11)刪除儲存過程
drop procedure sp_expexcle
go12）執行sql
declare @sql as varchar(100)
set @sql='select * from table'
exec @sql
13)sql傳引數
set @ncount=0
select @ncount=count(*) from hospital.dbo.hos_pickup where item=@itemid
