1. 现象 1
2. 原因:::sql server的bug 或者限制,查询的时候儿使用资源太多超过操作系统/防火墙/安全软件的限制... 2
2.1. 防火墙/安全软件的原因:自动关闭了长时连接and 资源多的连接.. 2
2.2. 并发连接数超过了其承载量,服务器会将其中一些连接Down掉; 2
3. 解决之道:: 2
3.1. 打补丁sp 2
3.2. 使用top n /where 减少查询数量(attialx验证ok) 2
3.3. 提升电脑配置(推荐,,验证ok) 2
3.4. 查询字段添加索引 2
3.5. 减少select 大的字段查询..只select 小的字段 2
3.6. 修改某一字段的长度,或许是这个造成的.. 3
3.7. strSql和Param太多了,导致错误。 3
3.8. 在调用存储过程中未指明详细的数据类型.(据google结果说打了sp4才出现的,这就不知道了) 3

1. 现象
执行一个sql 语句的时候儿这个错误..代码韩式管理器黑头都是中个..
解决“当前命令发生了严重错误。应放弃任何可能产生的结果。”的问题
在从服务器接收结果时发生传输级错误。 (provider: 命名管道提供程序, error: 0 - 管道的另一端上无任何进程。)
当前命令发生了严重错误。应放弃任何可能产生的结果
常常还有conn 自动关闭的事情....socket close..
org.springframework.transaction.TransactionSystemException: Could not roll back Hibernate transaction; nested exception is org.hibernate.TransactionException: rollback failed
org.springframework.transaction.CannotCreateTransactionException: Could not open Hibernate Session for transaction; nested exception is org.hibernate.service.UnknownServiceException: Unknown service requested [org.hibernate.service.jdbc.connections.spi.ConnectionProvider]
Caused by: com.microsoft.sqlserver.jdbc.SQLServerException: Connection reset by peer: socket write error
Caused by: com.microsoft.sqlserver.jdbc.SQLServerException: 该连接已关闭。

2. 原因:::sql server的bug 或者限制,查询的时候儿使用资源太多超过操作系统/防火墙/安全软件的限制...
数据只有75w,查询的时候儿也这个错误.....
大概查询的时候儿内存使用太多...
但是mysql 相同的电脑上 相同的数据数量就没问题..

估计是文章的长度太长导致的,于是查找到代码 db.AddInParameter(dbCommand, "Content", DbType.AnsiString, model.Content);
将其改为
db.AddInParameter(dbCommand, "Content", DbType.String, model.Content);
3.7. strSql和Param太多了,导致错误。
param for循环51 次即 2092 个就报错。
3.8. 在调用存储过程中未指明详细的数据类型.(据google结果说打了sp4才出现的,这就不知道了)

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
