b****u 发帖数: 1027 | 6 你这想法挺有意思,我想一般来说不需要这么做,如果你的情况真的需要,可以考虑
Stored Procedure 每步都更新一个 table, 然后你的客户端程序不断去读那个进程

I wonder if there is benefits for performance for Writing CLR Stored
Procedures in C# ? Thank you!
hai |
|
x**n 发帖数: 461 | 8 No. CLR stored procedure is just the database team's effort to get more work
/bonus. It doesn't help your performance at all because the database is not
designed to do such things. The best place to place your business logic is
still your middle tier. |

y********o 发帖数: 2565 | 9 I have never tried stored procedure in Java. So, I would like to give it a
shot.
I got the demo from Oracle and compiled this one: PLSQL.java, which is
attached in this post. This code uses Oracle XE's hr/hr schema. I've tried
some other code with plain SQL, and it runs just fine and returns employee
info from the employees table.
But, when I run this PLSQL, I get the following error, and I don't know what
it means. It looks like I get such error message for all codes involving

2. excute the stored procedure using sql tools, check if it works at all
3. check your jdbc grammer, and intercept your jdbc call to the db
and check against what you have in 2 |

F*******n 发帖数: 89 | 11 谢谢。这个stored procedure肯定是work的。用sql tool试验过的,没有问题。
我也很清楚expected的result。
我的database call也没有grammer问题。 |

你是指
select foo ();
工作,还是
insert table values (foo ());
工作,还是
update table set col = foo () where col = ...;
工作?
stored procedure 没写好的话,是可以出现前两个“工作”,但是到 update
的时候出问题的情形。比如,foo () 的结果是一 complex data structure,
这个 data structure 可能写的人没注意,只是 memory resident 的。但是
存到硬盘的结够必须是另外一种形式(比如 size header 等),因为有些
database 出于 performance 的考虑,所有的 in-memory data structure
得和硬盘 上的结构一一对应,并不提供 I/O wrapper 。这样的话,
in memory operation 是可以工作的。但是 store / load 在 database 里的
只是 memory pointer,没有实际的 |

g*****g 发帖数: 34805 | 15 这个我老N年前就总结过了。
ORM的好处,易维护,把计算量迁移应用服务器上,容易处理高并发,缓存简单,可在不
同数据库间移植。在高并发的应用里,关系型数据库本身不能scale out,早晚是个瓶
颈,所以ORM提高了系统能支持的并发数。最近几年NoSQL DB的发展,就是单机数据库
系统在ORM下仍然是瓶颈下的必然道路。
Stored procedure的好处,在低并发,大数据量的一些应用上,如每日产生的报表有离
数据近的优势。但不易维护。近年Oracle在数据库服务器上内建对Java的支持,就是为
了提高可维护性。
SP对单个请求比ORM快几乎是必然的。但100个并发的请求,就不见得一样了,10000个
并发的请求,整一个能撑住的数据库服务器,就要比一个小数据库+一个应用服务器ORM
集群,要贵无数倍。别忘了Oracle之类的数据库是按可比CPU算钱的。

l*******n 发帖数: 35 | 17 请益:
有个稀疏表,11万行,100列。每行大概1~10个数据,位置不定其余都是null
要数据处理,把数据都读一遍,需要读出value 和相应 column name
用jdbc分批读,发现读入resultset之后遍历要花40分钟。
纯用stored procedure读会不会效率高点? |

Any one has the standard procedure for any step from sampling to statistical
