对于下面代码的最后两个语句，生成实际的执行计划。您可以看到启动谓词 on@Par1被放置在不同的位置，这完全改变了来自test_fn1函数的实际行数。我需要控制这种行为。

create or alter function dbo.test_fn1(@Par1 varchar(100), @Par2 varchar(1))
returns @t table(item varchar(100))
as
begin
  insert into @t (item) select value from STRING_SPLIT(@Par1, @Par2);
  return
end
GO
create or alter function dbo.test_fn(@Par1 varchar(100), @Par2 varchar(100))
returns table
as
return (
  select s.*
    from dbo.test_fn1(@Par2,';') x
    inner join sys.objects s on s.name = x.item
    where @Par1 = 'CASE1'
)
GO
create or alter function dbo.test_fnx(@Par1 varchar(100), @Par2 
   varchar(100))

预热一个冷 MySQL 实例是将所有数据或最有可能习惯的数据移动到主内存中。而且，是的，通过主内存，我的意思是 InnoDB 缓冲池。缓冲池通常被配置为一大块主内存。将所有数据从磁盘获取到主内存需要时间。与其留到以后，缓冲池能否提前加载最期望最早使用的数据？

我在启动 SQL Server 2008 时遇到问题。我需要将数据库从一台计算机复制到 seced。我只DATA从我实际工作的服务器复制目录，然后将此目录复制到我新安装的 SQL Server 2008。在此之后，当我启动 SQL Server 时，它不会启动。

我的错误日志是：
