存储过程中遇到ORA-00942表或视图不存在
后来查资料得知如果用户有dba角色,角色里包含的权限在存储过程里不会被继承;所以又单独对tb_bil_acct_566 ,seq_bil_acct_his_
解决方法:
grant select, insert, update, delete on bookmarks.* to bm_user@localhost identified by 'password'
授权语句:意思是把表 XXX select, insert, update, delete权限授给bm_user表
以sys身份登录,为system赋予select 和delete sys.fga_log$的权限,,否则下边的存储过程添加会有问题。
Sql> grant select ,delete on sys.fga_log$ to system;
原因:
后来查资料得知如果用户有dba角色,角色里包含的权限在存储过程里不会被继承;所以又单独对tb_bil_acct_566 ,seq_bil_acct_his_hisid_566.nextval等作了显式赋权,问题得以解决。
grant 授权的授权结果从哪里看到?
grant select ,delete on sys.fga_log$ to system;--改的是哪个基表? --dba_tab_privs
select * from dba_tab_privs where grantee='SYSTEM' AND TABLE_NAME='FGA_LOG$'[@more@]grant select ,delete on sys.fga_log$ to system;--改的是哪个基表? --dba_tab_privs
select * from dba_tab_privs where grantee='SYSTEM' AND TABLE_NAME='FGA_LOG$

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.

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 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.

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. Insert data: INSERTINTObooks(title, author, published_year)VA

MySQL is suitable for web applications and content management systems and is popular for its open source, high performance and ease of use. 1) Compared with PostgreSQL, MySQL performs better in simple queries and high concurrent read operations. 2) Compared with Oracle, MySQL is more popular among small and medium-sized enterprises because of its open source and low cost. 3) Compared with Microsoft SQL Server, MySQL is more suitable for cross-platform applications. 4) Unlike MongoDB, MySQL is more suitable for structured data and transaction processing.

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 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.
