create procedure dba.GetMaxTMstmp_job
as
declare @tblname varchar(100)
declare mycursor cursor for select top 10 name from sys.tables where type= U order by name
– 打开游标
open mycursor
– 从游标里取出数据赋值到我们刚才声明的 2 个变量中
fetch next from mycursor into @tblname
– 判断游标的状态
— 0 fetch 语句成功
—1 fetch 语句失败或此行不在结果集中
—2 被提取的行不存在
while (@@fetch_status=0)
begin
print @tblname
exec dba.GetMaxTMstmp @tblname
fetch next from mycursor into @tblname
end
– 关闭游标
close mycursor
– 撤销游标
DEALLOCATE mycursor
