sql 在查询语句中将整数转为IP字符串实现语句
本文章介绍了关于sql 在查询语句中将整数转为IP字符串实现语句,有需要的同学可以参考一下下本文章
数据表的结构是——
代码如下 | 复制代码 |
CREATE TABLE [dbo].[ac_mainctls_new] ( [id] [int] NULL , [ctlip] [bigint] NULL , [ctlname] [char] (30) COLLATE Chinese_PRC_CI_AS NULL , ) |
其中ctlip是设备的IP地址,以整数方式存储。
虽然可以用程序将整数转为IP字符串,但多了一道工序有点麻烦。于是我想直接在SQL查询语句中将其转为IP字符串。
经过思索与调试,我完成了该查询语句——
代码如下 | 复制代码 |
SELECT CAST(ctlip / 0x1000000 AS varchar(3)) + '.' + CAST(ctlip / 0x10000 % 0x100 AS varchar(3)) + '.' + CAST(ctlip / 0x100 % 0x100 AS varchar(3)) + '.' + CAST(ctlip % 0x100 AS varchar(3)) AS itr, *FROM ac_mainctls_new |
复制代码
查询结果为——
ipstr ctlip
代码如下 | 复制代码 |
192.168.10.32 3232238112 192.168.10.35 3232238115 192.168.10.21 3232238101 192.168.10.19 3232238099 |

The main role of MySQL in web applications is to store and manage data. 1.MySQL efficiently processes user information, product catalogs, transaction records and other data. 2. Through SQL query, developers can extract information from the database to generate dynamic content. 3.MySQL works based on the client-server model to ensure acceptable query speed.

InnoDB uses redologs and undologs to ensure data consistency and reliability. 1.redologs record data page modification to ensure crash recovery and transaction persistence. 2.undologs records the original data value and supports transaction rollback and MVCC.

MySQL is an open source relational database management system, mainly used to store and retrieve data quickly and reliably. Its working principle includes client requests, query resolution, execution of queries and return results. Examples of usage include creating tables, inserting and querying data, and advanced features such as JOIN operations. Common errors involve SQL syntax, data types, and permissions, and optimization suggestions include the use of indexes, optimized queries, and partitioning of tables.

MySQL's position in databases and programming is very important. It is an open source relational database management system that is widely used in various application scenarios. 1) MySQL provides efficient data storage, organization and retrieval functions, supporting Web, mobile and enterprise-level systems. 2) It uses a client-server architecture, supports multiple storage engines and index optimization. 3) Basic usages include creating tables and inserting data, and advanced usages involve multi-table JOINs and complex queries. 4) Frequently asked questions such as SQL syntax errors and performance issues can be debugged through the EXPLAIN command and slow query log. 5) Performance optimization methods include rational use of indexes, optimized query and use of caches. Best practices include using transactions and PreparedStatemen

MySQL is chosen for its performance, reliability, ease of use, and community support. 1.MySQL provides efficient data storage and retrieval functions, supporting multiple data types and advanced query operations. 2. Adopt client-server architecture and multiple storage engines to support transaction and query optimization. 3. Easy to use, supports a variety of operating systems and programming languages. 4. Have strong community support and provide rich resources and solutions.

Compared with other programming languages, MySQL is mainly used to store and manage data, while other languages such as Python, Java, and C are used for logical processing and application development. MySQL is known for its high performance, scalability and cross-platform support, suitable for data management needs, while other languages have advantages in their respective fields such as data analytics, enterprise applications, and system programming.

MySQL is suitable for small and large enterprises. 1) Small businesses can use MySQL for basic data management, such as storing customer information. 2) Large enterprises can use MySQL to process massive data and complex business logic to optimize query performance and transaction processing.

MySQL index cardinality has a significant impact on query performance: 1. High cardinality index can more effectively narrow the data range and improve query efficiency; 2. Low cardinality index may lead to full table scanning and reduce query performance; 3. In joint index, high cardinality sequences should be placed in front to optimize query.
