本地没有装Oracle,PL/SQL远程访问Oracle数据库配置
去Oracle网站下载Instant Client,需要的人留言,给你发网盘链接。然后安装,我是直接安在了PL/SQL的安装目录里面,目录为:C:\p
之前写过一篇关于Oracle数据库远程连接的博客:Oracle数据库——服务端配置远程连接 。
在那篇文章中操作推荐过别人的一篇博客,就是本博客的这个话题。但是最近要用了,于是就翻自己的博客,却发现那个博客已经限制访问了,在网上又找了好久,才找到这个,于是果断自己写一下,以备今后自用以及方便他人。
1、安装PL/SQL,这个过程还是比较容易的,就不再多说了,我的目录为:C:\plsql
2、去Oracle网站下载Instant Client,需要的人留言,,给你发网盘链接。然后安装,我是直接安在了PL/SQL的安装目录里面,目录为:C:\plsql\odac_client。
3、在此目录中新建一个名为tnsnames.ora的文件,打开定入如下内容:
ORCL =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orcl)
)
)
4、添加名为TNS_ADMIN的环境变量,值为tnsnames.ora文件的路径
5、打开PL/SQL,直接点取消,就会进入主界面。选择Tools中的Preference,在里面设置Oracle Home为C:\plsql\odac_client,OCI Library为C:\plsql\odac_client\oci.dll。
6、配置完成后重启PL/SQL。
7、可能会碰到乱码的问题,只需要用下面命令查一下编码:
select userenv('language') from dual;
只需要添加一个环境变量NLS_LANG,值为上面语句查到的结果,就不会有乱码问题了。
最后,个人建议,我用的是有道笔记,对于看到的功能性博客(比如此篇),就收藏到里面,只是单纯的收藏一个地址还是不那么靠谱的,写此篇文章,只为提出一点建议,另自己的学习更加高效。

Full table scanning may be faster in MySQL than using indexes. Specific cases include: 1) the data volume is small; 2) when the query returns a large amount of data; 3) when the index column is not highly selective; 4) when the complex query. By analyzing query plans, optimizing indexes, avoiding over-index and regularly maintaining tables, you can make the best choices in practical applications.

InnoDB's full-text search capabilities are very powerful, which can significantly improve database query efficiency and ability to process large amounts of text data. 1) InnoDB implements full-text search through inverted indexing, supporting basic and advanced search queries. 2) Use MATCH and AGAINST keywords to search, support Boolean mode and phrase search. 3) Optimization methods include using word segmentation technology, periodic rebuilding of indexes and adjusting cache size to improve performance and accuracy.

Yes, MySQL can be installed on Windows 7, and although Microsoft has stopped supporting Windows 7, MySQL is still compatible with it. However, the following points should be noted during the installation process: Download the MySQL installer for Windows. Select the appropriate version of MySQL (community or enterprise). Select the appropriate installation directory and character set during the installation process. Set the root user password and keep it properly. Connect to the database for testing. Note the compatibility and security issues on Windows 7, and it is recommended to upgrade to a supported operating system.

The difference between clustered index and non-clustered index is: 1. Clustered index stores data rows in the index structure, which is suitable for querying by primary key and range. 2. The non-clustered index stores index key values and pointers to data rows, and is suitable for non-primary key column queries.

MySQL is an open source relational database management system. 1) Create database and tables: Use the CREATEDATABASE and CREATETABLE commands. 2) Basic operations: INSERT, UPDATE, DELETE and SELECT. 3) Advanced operations: JOIN, subquery and transaction processing. 4) Debugging skills: Check syntax, data type and permissions. 5) Optimization suggestions: Use indexes, avoid SELECT* and use transactions.

In MySQL database, the relationship between the user and the database is defined by permissions and tables. The user has a username and password to access the database. Permissions are granted through the GRANT command, while the table is created by the CREATE TABLE command. To establish a relationship between a user and a database, you need to create a database, create a user, and then grant permissions.
