ORA-02283: 无法变更启动序列号

Jun 10, 2016 pm 03:12 PM

如果想更新一个序列的start with值,是不可以直接更改的,会报错:SQLgt; alter sequence seq_xxrs start with 1000;alter sequ

如果想更新一个序列的start with值,是不可以直接更改的,会报错:

SQL> alter sequence seq_xxrs start with 1000;

alter sequence seq_xxrs start with 1000

ORA-02283: 无法变更启动序列号

那么,,如何增加一个序列的值呢?可以采用更改increment by的方式更改:

1.更改increment为一个你想让序列增加到的值

alter sequence seq_xxrs increment by 1000;

2.执行一次查询序列的语句

select seq_xxrs.nextval from dual;

3.然后将increment改回来

alter sequence seq_xxrs increment by 1;

此时的序列的值就增大了。

MySQL's Role: Databases in Web Applications MySQL's Role: Databases in Web Applications Apr 17, 2025 am 12:23 AM

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 vs. Other Programming Languages: A Comparison MySQL vs. Other Programming Languages: A Comparison Apr 19, 2025 am 12:22 AM

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.

How does MySQL index cardinality affect query performance? How does MySQL index cardinality affect query performance? Apr 14, 2025 am 12:18 AM

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.

MySQL for Beginners: Getting Started with Database Management MySQL for Beginners: Getting Started with Database Management Apr 18, 2025 am 12:10 AM

The basic operations of MySQL include creating databases, tables, and using SQL to perform CRUD operations on data. 1. Create a database: CREATEDATABASEmy_first_db; 2. Create a table: CREATETABLEbooks(idINTAUTO_INCREMENTPRIMARYKEY, titleVARCHAR(100)NOTNULL, authorVARCHAR(100)NOTNULL, published_yearINT); 3.

Explain the InnoDB Buffer Pool and its importance for performance. Explain the InnoDB Buffer Pool and its importance for performance. Apr 19, 2025 am 12:24 AM

InnoDBBufferPool reduces disk I/O by caching data and indexing pages, improving database performance. Its working principle includes: 1. Data reading: Read data from BufferPool; 2. Data writing: After modifying the data, write to BufferPool and refresh it to disk regularly; 3. Cache management: Use the LRU algorithm to manage cache pages; 4. Reading mechanism: Load adjacent data pages in advance. By sizing the BufferPool and using multiple instances, database performance can be optimized.

MySQL: Structured Data and Relational Databases MySQL: Structured Data and Relational Databases Apr 18, 2025 am 12:22 AM

MySQL efficiently manages structured data through table structure and SQL query, and implements inter-table relationships through foreign keys. 1. Define the data format and type when creating a table. 2. Use foreign keys to establish relationships between tables. 3. Improve performance through indexing and query optimization. 4. Regularly backup and monitor databases to ensure data security and performance optimization.
