可以做个REPLICATION FROM ORACLE TO SQL SERVER,然后用SSIS在SQL SERVER里LOAD,既然现在用SQL SERVER了,SSIS和REPLICATION应该熟悉了

来自主题: Database版 - 怎么学SQL SERVER
很多人问怎么学SQL SERVER啊?无非三部曲
看书SQL SERVER 2008 ADMINISTRATION的书简单看看
实践,SEARS有SQL 2008 DEVELOPER EDITION,买一个装在机器上,自己创建一个
DATABASE,比如ORDER SYSTEM,大家都在AMAZON上买过东西,怎么ORDER东西,需要什
么,看看AMAZON的INVOICE就知道了,第一次肯定设计不好,多弄几遍,怎么提取数据
,怎么INSERT, UPDATE,DELETE,如何JOIN
考试,微软有认证,去考一下可以提高很快。买认证用的书,做做网上的练习。

来自主题: Database版 - Need help on a strange SQL server problem
我有一个.net 程序用SqlBulkCopy 向一个SQL2008R2的表(tableA)中插入大概几百条
数据。用SQL Profiler 跟综发现所有 insert bulk 的命令都执行了,SQL Server 也
未返回任何错误。但如果用户执行
select * from tableA
有时会发现刚才插入的记录不在(不是总能重复,时有时无)。
我怀疑记录是在SQL Server Cache 中,未能及时写入硬盘,但不能肯定。
Any suggestions?
Thanks.

选一个数据库是因为很多人要做developer或者DBA,必须先着重一个数据库。Analyst
不用过深了解特定数据库。SQL对不同数据库基本相同,学哪个都一样(Oracle or SQL

是可以的,但可能会遇到很多问题,再说你SQL SERVER的SCHEMA跟ORACLE一模一样么,
还是别人给做好了DATA MODEL,你往里灌数据呢,如果是灌数据,就得SSIS ETL了,
我很好奇为什么换系统,PERFORMANCE不好,还是ORACLE太贵了用不起,一般换系统,
我肯定走人的,换完了人就不要你了,我给一家从SQL SERVER换到ORACLE,用从ORACLE
换回SQL SERVER,还没换完就被LAY了,后来又看到几家换系统,一看是换系统就说明

最近想换个SQL DBA/Developer的工作,很不顺利。
现在想请教大家两个有关找工作的问题:
1。哪些网站搜寻SQL DBA/Developer职位?比如我上Monster寻找Houston的SQL DBA/
Developer,根本没有多少职位。请问哪些网站搜寻DBA/Developer职位比较有效?
2。请大家推荐资料面试。经常看到程序员讨论某些秘籍通杀MS或者GOOGLE难题。数据
库是不是也有类似的秘籍,或者临时抱佛脚的速成书?偶然的机会转行做了几年DBA,
但从没静下来好好学习过。现在也不大可能静下读书,所以大部头的书估计读不下来,
最好是那种速成资料,针对面试的更好。

Free eBook: SQL Server Transaction Log Management
When a SQL Server database is operating smoothly and performing well, there
is no need to be particularly aware of the transaction log, beyond ensuring
that every database has an appropriate backup regime and restore plan in
place. When things go wrong, however, a DBA's reputation depends on a deeper
understanding of the transaction log, both what it does, and how it works.

我在做一个项目,要求在1个小时的窗口内,把整个数据库全部更新一次(头的要求很奇怪
,要full,不能incremental).现在的瓶颈在一个BLOB的字段上,这个字段存放一个Object

我在网上找的例子用SQL LOADER 做LOB,全部是文本CLOB的例子,看不到BLOB的例子,
BLOB的例子也有,但是都是从不同的文件载入的,比如说一条记录对应一个外部文件. 这
对我来说不现实,在本地盘上装2M个文件会慢得要死.我现在的办法是把BLOB变成BASE64
,到了ORACLE里面再把BASE64 decode成BLOB,这样可以把数据搞上去,但是这个数据内解
码耽误时间,速度达不到要求,很慢.
我希望的方法是把所有记录的BLOB内容放在一个文件里,然后用LOBFILE constant指定
一个文件名,所有的记录都在这个文件里找内容,现在的问题是我不知道怎么样把各条记
