由于window下没有装oracle，于是安装了一个oracle instant client 先配置tnsname.ora 位于D:\dev_software\oracle\product\11.2.0\client_1\network\admin 如果没有则从改目录下的sample拷贝一个出来添加，如下配置 ORCL为数据库名 host后面是数据库ip port

由于window下没有装oracle，于是安装了一个oracle instant client

先配置tnsname.ora

位于D:\dev_software\oracle\product\11.2.0\client_1\network\admin

如果没有则从改目录下的sample拷贝一个出来

添加，如下配置

ORCL为数据库名

host后面是数据库ip

port为端口

SERVICE_NAME 为centos安装配置的oracle sid

ORCL=
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.10)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orcl)
)
)

（可以安装一个plsql 来测试是否成功）

参考该网站http://www.2cto.com/database/201305/212209.html

完成odbc数据源的配置

如果找不到oracle的数据库，需要从官网下载odbc安装包

最后需要注意的一点是在通过代码连接数据库时

m_retcode = SQLConnect(m_hdbc, (SQLCHAR*) m_szServerName, SQL_NTS, (SQLCHAR*) m_szUserName, SQL_NTS, (SQLCHAR*) m_szPassWord, SQL_NTS);

其中m_szServerName 为上面配置的ORCL

m_szUserName 为配置odbc数据源时的用户名

m_szPassWord 为对应的密码

odbc连接数据库代码，可以参考

What is MySQL partitioning?Apr 27, 2025 am 12:23 AM

MySQL partitioning improves performance and simplifies maintenance. 1) Divide large tables into small pieces by specific criteria (such as date ranges), 2) physically divide data into independent files, 3) MySQL can focus on related partitions when querying, 4) Query optimizer can skip unrelated partitions, 5) Choosing the right partition strategy and maintaining it regularly is key.

How do you grant and revoke privileges in MySQL?Apr 27, 2025 am 12:21 AM

How to grant and revoke permissions in MySQL? 1. Use the GRANT statement to grant permissions, such as GRANTALLPRIVILEGESONdatabase_name.TO'username'@'host'; 2. Use the REVOKE statement to revoke permissions, such as REVOKEALLPRIVILEGESONdatabase_name.FROM'username'@'host' to ensure timely communication of permission changes.

Explain the differences between InnoDB and MyISAM storage engines.Apr 27, 2025 am 12:20 AM

InnoDB is suitable for applications that require transaction support and high concurrency, while MyISAM is suitable for applications that require more reads and less writes. 1.InnoDB supports transaction and bank-level locks, suitable for e-commerce and banking systems. 2.MyISAM provides fast read and indexing, suitable for blogging and content management systems.

What are the different types of JOINs in MySQL?Apr 27, 2025 am 12:13 AM

There are four main JOIN types in MySQL: INNERJOIN, LEFTJOIN, RIGHTJOIN and FULLOUTERJOIN. 1.INNERJOIN returns all rows in the two tables that meet the JOIN conditions. 2.LEFTJOIN returns all rows in the left table, even if there are no matching rows in the right table. 3. RIGHTJOIN is contrary to LEFTJOIN and returns all rows in the right table. 4.FULLOUTERJOIN returns all rows in the two tables that meet or do not meet JOIN conditions.

What are some common security vulnerabilities in MySQL?Apr 26, 2025 am 12:27 AM

Common security vulnerabilities in MySQL include SQL injection, weak passwords, improper permission configuration, and unupdated software. 1. SQL injection can be prevented by using preprocessing statements. 2. Weak passwords can be avoided by forcibly using strong password strategies. 3. Improper permission configuration can be resolved through regular review and adjustment of user permissions. 4. Unupdated software can be patched by regularly checking and updating the MySQL version.

How can you identify slow queries in MySQL?Apr 26, 2025 am 12:15 AM

Identifying slow queries in MySQL can be achieved by enabling slow query logs and setting thresholds. 1. Enable slow query logs and set thresholds. 2. View and analyze slow query log files, and use tools such as mysqldumpslow or pt-query-digest for in-depth analysis. 3. Optimizing slow queries can be achieved through index optimization, query rewriting and avoiding the use of SELECT*.
