How to view the history of executed SQL commands in db2?

You can view the SQL execution history in DB2 using the following methods:

1. 使用命令行工具：可以通过在命令行中执行db2 get snapshot for dynamic sql on 命令来获取SQL执行历史记录。其中是要查看历史记录的数据库名称。执行该命令后，会返回包含SQL执行历史记录的结果集。
2. Utilize system monitoring tables: DB2 offers some system monitoring tables that allow you to query the history of SQL executions. For example, you can use the following query statement to retrieve the historical records of the 100 most recently executed SQL statements.
3. Retrieve all rows from the sysibm.sysdynsql table, ordering them by the sql_exec_start column in descending order. Limit the results to the first 100 rows.
4. Use DB2 Control Center or DB2 Visual Explain tool: These visual tools offer a more intuitive and convenient way to view the SQL execution history. By connecting to the database and navigating to the appropriate options, you can easily see and analyze the SQL execution history.
