Как посмотреть sql-код выполняемой транзакции, зная transaction_id?

@margaret 

Transaction ID (также известный как XID) - это уникальный идентификатор, назначаемый каждой транзакции в базе данных. Он используется для отслеживания и управления транзакциями.

Чтобы просмотреть SQL-код, выполняемый в транзакции, зная transaction_id, вы можете выполнить следующие действия, в зависимости от используемой СУБД:

• MySQL:

1
2

mysql> SELECT * FROM information_schema.innodb_trx
WHERE trx_id = 'transaction_id';

• PostgreSQL:

1
2

postgres=> SELECT * FROM pg_stat_activity
WHERE transction_id = 'transaction_id';

• Oracle:

1
2

SQL> SELECT * FROM v$transaction
WHERE xid = 'transaction_id';

• MS SQL Server:

1
2
3
4
5

USE master;
GO
SELECT * FROM sys.dm_tran_active_transactions
WHERE transaction_id = 'transaction_id';
GO

Однако, получить детальную информацию о SQL-коде, выполняемом в транзакции, может быть сложным и требует дополнительных инструментов, таких как профайлеры или журналы транзакций.

Be aware that retrieving the exact SQL code executed within a transaction solely from the transaction_id can be complex and not always possible depending on the database management system you are using. The transaction_id only represents a unique identifier for a transaction and does not necessarily contain the complete SQL code.

If you want to capture the SQL code within a transaction, it is recommended to use the appropriate tools provided by your database management system. Some options include:

1. Database Profiler: Most database management systems offer built-in profiling tools that allow monitoring and capturing SQL statements executed within transactions. These tools often provide detailed information about the queries, execution plans, and other relevant metrics. Refer to the documentation or user guides specific to your database system to learn how to use the profiler effectively.
2. Transaction Logs: Transaction logs contain a detailed record of all the changes made to the database, including the SQL code executed within each transaction. Analyzing the transaction logs can provide insight into the executed queries. However, accessing and interpreting transaction logs may require advanced knowledge and specific tools provided by the database system.
3. Query Execution History: Some database systems keep track of query execution history, which can include information about the SQL code executed within a transaction. Check the documentation or user guides for your database system to determine if this feature is available and how to access it.
4. Third-Party Monitoring Tools: There are various third-party tools available that specialize in monitoring and capturing SQL queries executed within transactions. These tools often provide more comprehensive functionality and a user-friendly interface for analyzing and retrieving SQL code. Research and select a tool that is compatible with your database management system and meets your specific requirements.

Remember that the availability and effectiveness of these methods may vary depending on your database management system and its configuration. It is recommended to consult the documentation and resources specific to your database system for more accurate and detailed instructions.
