怎样备考雅思
假期实践报告存储过程中将查询语句结果赋值给变量create procedure procname
圣诞快乐用英语怎么说AS
declare @recount int
lect @recount=count(id) from school
--最关键在这句exelon
lect @recount=count(id) from school
lect @recount=lect count(id) from school -- 错误：这⾥就不再需要lect了
t @recount=count(id) from school -- 错误这⾥只能⽤lect不能⽤t
如果school为⼀个@chart参数的话，上⾯⽅法就不适⽤了
应该为:
declare @getRecordSql nvarchar(100)
t @getRecordSql='lect @recordcount=count(1) from '+@chart
exec sp_executesql @getRecordSql,N'@recordCount int output',@recordCount output
N'@recordCount int output',@recordCount output
做⼀个参数的替换，如果测试⼀下:print @recordCount的话就会显⽰⾏数
//⽰例：选择最新的5条数据从20条开始
execute A_School_getNew 5,20
--存储过程
create procedure A_School_getNew
@Size int,
cereal
@StartIndex int

declare @recount int
declare @Sql nvarchar(120)
lect @recount=count(id) from school
asylumt @Sql='lect top '+convert(nvarchar,@Size)+'id,school_name from school where('+gmv是什么意思
'ID not in(lect top '+convert(nvarchar,@recount-@startIndex+@size)+
' id from school)) order by id desc';
