ORA-00911,"911"看着很霸气的错误号,虽然我还是Oracle的初学者,但每次碰到一个未见过的ORA错误号后,都有一种查案的赶脚,根据错误号、OERR、相关错误信息,判断错误原因以及找到解决方案或替代方案,虽然大部分可能还是参考前辈或官方,但碰到一次后,至少是似曾相识了,再次碰到时即使不记得,大概也能有个方向。
话说回来,这个ORA-00911的错误,是在一段用JAVA写的测试用例中碰到的,
...
private static final String SQL_INSERT_TBL = "insert into tbl (id, ...) "
+ "values (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, SYSDATE, SYSDATE);";
报的是这段SQL有这个错误。
看看错误描述:
ORA-00911 invalid character
Cause: Special characters are valid only in certain places. If special characters other than $, _, and # are used in a name and the name is not enclosed in double quotation marks ("), this message will be issued. One exception to this rule is for database names; in this case, double quotes are stripped out and ignored.
Action: Remove the invalid character from the statement or enclose the object name in double quotation marks.
很明显,这个错误主要是因为SQL中包含了非法字符,解析的时候出现报错。
但这个SQL很简单啊,就是一条INSERT语句,将他拷贝到plsql developer中好像是可以的啊,奇怪了。
调试很多次后,忽然发现,定义中结尾有个“;”,难道是这个的问题?
于是首先在plsql developer中执行INSERT语句,结尾带了两个“;”,果然报了这个ORA-00911错误。
修改代码中的语句:
private static final String SQL_INSERT_TBL = "insert into tbl (id, ...) "
+ "values (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, SYSDATE, SYSDATE)";
果然,正常回显了。
一个看似简单,但挑错较麻烦的错误,值得自己的总结。
1. OERR错误描述是基准,要顺着这个方向排查,基本方向可以明确。
2. 代码中出现的SQL错误,可以在plsql developer等工具中重新执行来模拟错误,但一定要和代码中的SQL语句一样,这里我可能拷贝的时候就没有带结尾的;,以至于第一次没有发现这个错误,总之一句话,除了需要判断大方向,最重要的一点就是细心,不要放过任何一个小的细节。
可以参考杨长老曾经一样遇到的这个ORA-00911错误:

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.

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 worth learning because it is a powerful open source database management system suitable for data storage, management and analysis. 1) MySQL is a relational database that uses SQL to operate data and is suitable for structured data management. 2) The SQL language is the key to interacting with MySQL and supports CRUD operations. 3) The working principle of MySQL includes client/server architecture, storage engine and query optimizer. 4) Basic usage includes creating databases and tables, and advanced usage involves joining tables using JOIN. 5) Common errors include syntax errors and permission issues, and debugging skills include checking syntax and using EXPLAIN commands. 6) Performance optimization involves the use of indexes, optimization of SQL statements and regular maintenance of databases.

MySQL is suitable for beginners to learn database skills. 1. Install MySQL server and client tools. 2. Understand basic SQL queries, such as SELECT. 3. Master data operations: create tables, insert, update, and delete data. 4. Learn advanced skills: subquery and window functions. 5. Debugging and optimization: Check syntax, use indexes, avoid SELECT*, and use LIMIT.

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.

MySQL is an open source relational database management system that is widely used in Web development. Its key features include: 1. Supports multiple storage engines, such as InnoDB and MyISAM, suitable for different scenarios; 2. Provides master-slave replication functions to facilitate load balancing and data backup; 3. Improve query efficiency through query optimization and index use.

SQL is used to interact with MySQL database to realize data addition, deletion, modification, inspection and database design. 1) SQL performs data operations through SELECT, INSERT, UPDATE, DELETE statements; 2) Use CREATE, ALTER, DROP statements for database design and management; 3) Complex queries and data analysis are implemented through SQL to improve business decision-making efficiency.

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
