I am glad it helps because I made similar mistake before
although it was solely in PL/SQL. :-)
For Visual C++, you can get it from MSDN library and I found
it better than anything in written. :-)
For Oracle, I guess you must have Oracle database installed.
Then you can find it under Oracle Documentation link. Then
you can search for Sequence string.

In fact, POINTER is not the basic data type of ORACLE.
Orcacle support NUMERIC and VARCHAR2,LOB, etc.
Since you can use Pro*C( or OCI) to develop Oracle
applciations,
the benefit of standard C language can be realized in such
type of applications.
Please reference to the Pro*C development guide of ORACLE.

According to my experience in DB2 and Informix, batch insert
commit(usually about thousands of record) is faster than
single record or less than one hundred record commit. I
think in Oracle it should work too. Also, in oracle, there
should have some parameters to be adjusted for performance.
You can ask some oracle experts.

login using sql plus and do all your work there. But for

A good idea is to run a linux box(586is enough) install a oracle

As long as the path is not retired by Oracle, you

Be prepared for 24/7 on call for DBA. If your shop stick to Oracle,

现在老板要求在Oracle把一个Number类型,转变成一个IP地址,而且不能用JDBC,ODBC。
其实我认为就是先把Number类型转换成Binary类型,再按8位分组,再把8位转变成NUMBER

Did you investigate before you say there is no such thing in Oracle.
I guess you don't like Oracle because you have little experiences with it :P

来自主题: Database版 - oracle能开多大的连接池?
谢谢
现在还想到一个解决的方法就是
1.在繁忙时(一年中就只有几天时间,一个月左右吧)用高级复制
这样有二台oracle,一台用来读,一台用来写或是二台都能读写
用高级复制的话对硬件的要求不是太高
但听说如果写数据量大的话,高级复制会有很多问题出现
2.用Logical Standby
Logical Standby、的Standby的数据库可以给应用程序读访问
那也行啊,可以缓解好大的压力
但用Standby技术对硬件要求太高
有点儿为难
3.干脆用一个MySQL,e用来进行写
用户提交的数据(只有在一张表中)都先保存到这
而另一程序同时从MySQL中读数据到Oracle里
数据处理放在主数据库Oracle中
但这还是有一个数据不一致性问题
因为数据处理有较强的实时性
根据提交时间的先后排队处理的
上面三个方案哪一个更可行?
