倒是对报告的结果感到很大的惊奇!
Mysql5出来了
前几天看见有人说Mysql5支持存储过程,今天到Mysql.com上看了看,果然啊。而且还不止这些呢,不过看完了这个觉得就存储过程还觉得比较使用,其他的感觉倒是一般。
The following features are planned for inclusion into MySQL 5.0. Some of the features such as stored procedures are complete and are included in MySQL 5.0 alpha, which is available now. Others such as cursors are only partially available. Expect these and other features to mature and be fully supported in upcoming releases.
Note that because we have many developers that are working on different projects, there will also be many additional features. There is also a small chance that some of these features will be added to MySQL 4.1. For a list what is already done in MySQL 4.1, see section 1.5.2.1 Features Available in MySQL 4.1.
For those wishing to take a look at the bleeding edge of MySQL development, we make our BitKeeper repository for MySQL version 5.0 publicly available. See section 2.3.3 Installing from the Development Source Tree. As of December 2003, binary builds of version 5.0 are also available.
- Stored Procedures
-
- Stored procedures are currently implemented, based on the SQL:2003 standard. See section 19 Stored Procedures and Functions.
- New functionality
-
- Elementary cursor support. See section 19.1.8 Cursors.
- The ability to specify explicitly for
MyISAMtables that an index should be created as anRTREEindex. (In MySQL 4.1,RTREEindexes are used internally for geometrical data that use GIS datatypes, but cannot be created on request.) - Dynamic length rows for
HEAPtables.
- Standards compliance, portability and migration
-
- Add true
VARCHARsupport (column lengths longer than 255, and no stripping of trailing whitespace). (There is already support for this in theMyISAMstorage engine, but it is not yet available at the user level.)
- Add true
- Speed enhancements
-
SHOW COLUMNS FROM tbl_name(used bymysqlclient to allow expansions of column names) should not open the table, only the definition file. This will require less memory and be much faster.- Allow
DELETEonMyISAMtables to use the record cache. To do this, we need to update the threads record cache when we update the `.MYD’ file. - Better support for
MEMORY(HEAP) tables:- Dynamic length rows.
- Faster row handling (less copying).
- Usability enhancements
-
- Resolving the issue of
RENAME TABLEon a table used in an activeMERGEtable possibly corrupting the table.

大师毕竟是大师
昨天看了一本Rasmus Lerdorf写的关于PHP的一本书,
感觉就是不一样哦。:P
大师就是大师,
里面关于Pear:DB、模板(Smarty)、结合Apache安装时的提供的更多安全设置等等的介绍,虽然短短数言,但是却然我豁然开朗。
再列举一些这方面的链接:
