create??procedure?procname
AS
declare?@recount?int
select?@recount=count(id)?from?school

--最關(guān)鍵在這句
select?@recount=count(id)?from?school
select?@recount=select?count(id)?from?school?--?錯(cuò)誤:這里就不再需要select了

set?@recount=count(id)?from?school?--?錯(cuò)誤這里只能用select不能用set

?如果school為一個(gè)@chart參數(shù)的話，上面方法就不適用了
應(yīng)該為:

?

declare?@getRecordSql?nvarchar(100)?
set?@getRecordSql='select?@recordcount=count(1)?from?'+@chart
exec?sp_executesql?@getRecordSql,N'@recordCount?int?output',@recordCount?output
N'@recordCount int output',@recordCount output
做一個(gè)參數(shù)的替換,如果測(cè)試一下:print @recordCount的話就會(huì)顯示行數(shù)

?

?//示例:選擇最新的5條數(shù)據(jù)從20條開(kāi)始

?

execute?A_School_getNew?5,20

--存儲(chǔ)過(guò)程

create?procedure?A_School_getNew
?@Size?int,
?@StartIndex?int

declare?@recount?int
declare?@Sql?nvarchar(120)
