How to remove newline characters in oracle
Special symbols ascii definition: Both newline characters and carriage return characters need to be removed.
Line feed character chr(10)
Carriage return character chr(13)
The syntax is as follows:
select replace(replace(列名,CHR(10),\'\'),chr(13),\'\') from 表名;
or
select translate(列名,chr(13)||chr(10),\',\') from 表名;
Extended knowledge:
Use repalce in nested form, please note that only one symbol can be submitted at a time, such as carriage return first and then line feed
select REPLACE(gg, chr(10), '') from dual
Please pay attention to chr(13) | | chr (10) This type of combination is often used. Carriage return and line feed look better in notepad, so this situation should be considered.
select translate(string,chr(13)||chr(10),',') from dual;
Symbol processing of large character objects
For symbol processing in the clob field, first to_char and then process it in the same way
SQL> select to_char(vcl),replace(to_char(vcl),chr(10),'[]') from test_1;

MySQL uses GPL and commercial licenses for small and open source projects; Oracle uses commercial licenses for enterprises that require high performance. MySQL's GPL license is free, and commercial licenses require payment; Oracle license fees are calculated based on processors or users, and the cost is relatively high.

Oracle's evolution from database to cloud services demonstrates its strong technical strength and market insight. 1. Oracle originated in the 1970s and is famous for its relational database management system, and has launched innovative functions such as PL/SQL. 2. The core of Oracle database is relational model and SQL optimization, which supports multi-tenant architecture. 3. Oracle cloud services provide IaaS, PaaS and SaaS through OCI, and AutonomousDatabase performs well. 4. When using Oracle, you need to pay attention to the complex licensing model, performance optimization and data security issues in cloud migration.

Oracle is suitable for enterprise-level applications that require high performance and complex queries, and MySQL is suitable for web applications that are rapidly developed and deployed. 1. Oracle supports complex transaction processing and high availability, suitable for financial and large ERP systems. 2.MySQL emphasizes ease of use and open source support, and is widely used in small and medium-sized enterprises and Internet projects.

The differences in user experience between MySQL and Oracle are mainly reflected in: 1. MySQL is simple and easy to use, suitable for quick access and high flexibility scenarios; 2. Oracle has powerful functions, suitable for scenarios that require enterprise-level support. MySQL's open source and free features attract startups and individual developers, while Oracle's complex features and tools meet the needs of large enterprises.

The difference between MySQL and Oracle in performance and scalability is: 1. MySQL performs better on small to medium-sized data sets, suitable for fast scaling and efficient reading and writing; 2. Oracle has more advantages in handling large data sets and complex queries, suitable for high availability and complex business logic. MySQL extends through master-slave replication and sharding technologies, while Oracle achieves high availability and scalability through RAC.

Key features of Oracle software include multi-tenant architecture, advanced analytics and data mining, real-time application clustering (RAC), and automated management and monitoring. 1) A multi-tenant architecture allows for the management of multiple independent databases in one database instance, simplifying management and reducing costs. 2) Advanced analytics and data mining tools such as Oracle Advanced Analytics and OracleDataMining help extract insights from data. 3) Real-time application cluster (RAC) provides high availability and scalability, improving system fault tolerance and performance. 4) Automated management and monitoring tools such as Oracle EnterpriseManager (OEM) to automate daily maintenance tasks and monitor numbers in real time

Oracle has a profound impact in the fields of data management and enterprise applications. Its database is known for its reliability, scalability and security, and is widely used in industries such as finance, medical care and government. Oracle's influence has also expanded to middleware and cloud computing fields such as WebLogicServer and OracleCloudInfrastructure (OCI), providing innovative solutions. Despite the competition in the open source database and cloud computing market, Oracle maintains its leading position through continuous innovation.

Oracle's mission is to "help people see the value of data", and its core values include: 1) Customer first, 2) Integrity, 3) Innovation, and 4) Teamwork. These values guide Oracle's strategic decision-making and business innovation in the market.
