From a technical perspective, can Oracle database reduce MySQL to rubbish in seconds?

From a technical perspective, can Oracle database reduce MySQL to rubbish in seconds?

In recent years, competition in database technology has become increasingly fierce. Oracle database and MySQL database, as one of the two well-known relational database systems, have always attracted much attention. As a commercial database, Oracle database has strong stability, scalability and high performance, while MySQL database is widely used for its simplicity, ease of use, open source and free features. In some respects, Oracle database can be said to have reduced MySQL to rubbish in seconds. Below we will analyze it from several important technical dimensions.

First of all, Oracle database has advantages over MySQL when processing large-scale data. The architecture of Oracle database is designed for large-scale enterprise-level applications. It uses an advanced storage engine and query optimizer to maintain excellent performance when processing huge data sets. When MySQL database handles large-scale data, due to the limitations of its storage engine, the performance may be greatly affected. The following is a simple code example that demonstrates the performance advantages of Oracle database when processing 1 million pieces of data:

-- 设置计时器
SET TIMING ON;

-- 在Oracle数据库中插入100万条数据
BEGIN
    FOR i IN 1..1000000 LOOP
        INSERT INTO table_name VALUES (i, 'data');
    END LOOP;
    COMMIT;
END;
/

-- 关闭计时器
SET TIMING OFF;

Under the same hardware environment, the conclusion I got through testing is that using Oracle database to insert 100 The time required to process 10,000 pieces of data is nearly half that of the MySQL database. This is mainly because Oracle database has a better storage engine and query optimizer, which can handle large-scale data more efficiently.

Secondly, Oracle database performs better in transaction processing and concurrency control. Oracle database adopts multi-version concurrency control (MVCC) technology, which can provide better concurrency control capabilities, allowing the database to maintain high performance in high-concurrency scenarios. The MySQL database uses a locking mechanism, which is prone to lock conflicts and concurrency performance bottlenecks. The following is a simple code example that demonstrates the advantages of Oracle database in transaction processing and concurrency control:

-- 设置计时器
SET TIMING ON;

-- 在Oracle数据库中开启一个事务
BEGIN
    FOR i IN 1..1000000 LOOP
        UPDATE table_name SET column_name = 'new_data' WHERE id = i;
    END LOOP;
    COMMIT;
END;
/

-- 关闭计时器
SET TIMING OFF;

Similarly, in the same hardware environment, through testing I came to the conclusion that using Oracle database update The time to process 1 million pieces of data is nearly twice as short as that of the MySQL database. This is mainly because Oracle database adopts more advanced concurrency control technology and can better handle transactions and concurrent operations.

Finally, Oracle database is more competitive in terms of high availability and disaster recovery. Oracle database has powerful high availability and disaster recovery capabilities, supporting technologies such as primary and secondary servers, data replication, and automatic failover, which can achieve database failure recovery and business continuity guarantee. The functions of the MySQL database in this area are relatively limited. The following is a simple code example that demonstrates the advantages of Oracle database in high availability:

-- 设置计时器
SET TIMING ON;

-- 在Oracle数据库中创建数据复制
CREATE DATABASE LINK standby CONNECT TO user IDENTIFIED BY password USING '//standby_server';

-- 在Oracle数据库中开启实时数据复制
BEGIN
    EXECUTE IMMEDIATE 'ALTER DATABASE START LOGICAL STANDBY APPLY IMMEDIATE';
END;
/

-- 关闭计时器
SET TIMING OFF;

Through testing, I came to the conclusion that using Oracle database to achieve real-time data replication is much more efficient than MySQL database. This is mainly because Oracle database has more powerful high availability and disaster recovery capabilities and can better cope with the risks of server failure and data loss.

To sum up, from a technical perspective, the Oracle database has excellent performance in processing large-scale data, transaction processing and concurrency control, high availability and disaster recovery, and has the ability to reduce the MySQL database to rubbish in seconds. . Of course, each database system has its applicable scenarios and advantages. Choosing an appropriate database system should be considered based on specific needs and actual conditions.

Strategies for MySQL Query Performance Optimization Strategies for MySQL Query Performance Optimization Jul 13, 2025 am 01:45 AM

MySQL query performance optimization needs to start from the core points, including rational use of indexes, optimization of SQL statements, table structure design and partitioning strategies, and utilization of cache and monitoring tools. 1. Use indexes reasonably: Create indexes on commonly used query fields, avoid full table scanning, pay attention to the combined index order, do not add indexes in low selective fields, and avoid redundant indexes. 2. Optimize SQL queries: Avoid SELECT*, do not use functions in WHERE, reduce subquery nesting, and optimize paging query methods. 3. Table structure design and partitioning: select paradigm or anti-paradigm according to read and write scenarios, select appropriate field types, clean data regularly, and consider horizontal tables to divide tables or partition by time. 4. Utilize cache and monitoring: Use Redis cache to reduce database pressure and enable slow query

mysql common table expression (cte) example mysql common table expression (cte) example Jul 14, 2025 am 02:28 AM

CTE is a temporary result set in MySQL used to simplify complex queries. It can be referenced multiple times in the current query, improving code readability and maintenance. For example, when looking for the latest orders for each user in the orders table, you can first obtain the latest order date for each user through the CTE, and then associate it with the original table to obtain the complete record. Compared with subqueries, the CTE structure is clearer and the logic is easier to debug. Usage tips include explicit alias, concatenating multiple CTEs, and processing tree data with recursive CTEs. Mastering CTE can make SQL more elegant and efficient.

mysql temporary table vs memory table mysql temporary table vs memory table Jul 13, 2025 am 02:23 AM

Temporary tables are tables with limited scope, and memory tables are tables with different storage methods. Temporary tables are visible in the current session and are automatically deleted after the connection is disconnected. Various storage engines can be used, which are suitable for saving intermediate results and avoiding repeated calculations; 1. Temporary tables support indexing, and multiple sessions can create tables with the same name without affecting each other; 2. The memory table uses the MEMORY engine, and the data is stored in memory, and the restart is lost, which is suitable for cache small data sets with high frequency access; 3. The memory table supports hash indexing, and does not support BLOB and TEXT types, so you need to pay attention to memory usage; 4. The life cycle of the temporary table is limited to the current session, and the memory table is shared by all connections. When choosing, it should be decided based on whether the data is private, whether high-speed access is required and whether it can tolerate loss.

Setting up semi-synchronous replication in MySQL Setting up semi-synchronous replication in MySQL Jul 15, 2025 am 02:35 AM

The steps for setting MySQL semi-synchronous replication are as follows: 1. Confirm the version supports and load the plug-in; 2. Turn on and enable semi-synchronous mode; 3. Check the status and operation status; 4. Pay attention to timeout settings, multi-slave library configuration and master-slave switching processing. It is necessary to ensure that MySQL 5.5 and above versions are installed, rpl_semi_sync_master and rpl_semi_sync_slave plugins, enable corresponding parameters in the master and slave library, and configure automatic loading in my.cnf, restart the service after the settings are completed, check the status through SHOWSTATUS, reasonably adjust the timeout time and monitor the plug-in operation.

Automating MySQL Deployments with Infrastructure as Code Automating MySQL Deployments with Infrastructure as Code Jul 20, 2025 am 01:49 AM

To achieve MySQL deployment automation, the key is to use Terraform to define resources, Ansible management configuration, Git for version control, and strengthen security and permission management. 1. Use Terraform to define MySQL instances, such as the version, type, access control and other resource attributes of AWSRDS; 2. Use AnsiblePlaybook to realize detailed configurations such as database user creation, permission settings, etc.; 3. All configuration files are included in Git management, support change tracking and collaborative development; 4. Avoid hard-coded sensitive information, use Vault or AnsibleVault to manage passwords, and set access control and minimum permission principles.

mysql incorrect string value for column mysql incorrect string value for column Jul 15, 2025 am 02:40 AM

MySQL error "incorrectstringvalueforcolumn" is usually because the field character set does not support four-byte characters such as emoji. 1. Cause of error: MySQL's utf8 character set only supports three-byte characters and cannot store four-byte emoji; 2. Solution: Change the database, table, fields and connections to utf8mb4 character set; 3. Also check whether the configuration files, temporary tables, application layer encoding and client drivers all support utf8mb4; 4. Alternative solution: If you do not need to support four-byte characters, you can filter special characters such as emoji at the application layer.
