A subquery is a query statement nested in another SQL query and is often used to dynamically obtain values or sets of values for use by the main query. It can appear in SELECT, FROM, WHERE or HAVING clauses, and is most commonly compared in WHERE conditions, such as finding employees whose salary is higher than the average salary; subqueries can also be used to generate derivative tables, as field expressions, or perform existence checks; performance issues should be paid attention to when using them, especially the related subqueries may be repeated execution to affect efficiency; at the same time, to ensure that the return result type matches, a single-value comparison needs to return a value, and multiple-value comparisons can be handled by operators such as IN and EXISTS; appropriate use of alias and brackets can improve readability and avoid syntax errors; in some cases, JOIN operations can

tracert is a tool in Windows for diagnosing network connectivity issues, helping to identify delays, timeouts, or routing issues by showing every hop the data passes from the computer to the target server. 1. Open the command prompt: Press Win R, enter cmd and press Enter. 2. Perform basic tracking: Enter tracertgoogle.com (replace the target with the desired URL or IP). 3. Interpretation result: Each hop shows three response times, high latency may indicate congestion, asterisks (*) indicate no response, which may be firewall shielding or device failure. 4. Use optional parameters: -d skip host name resolution, -h sets the maximum number of hops, and -w increases the timeout time. 5. Practical application scenarios include detecting that the website is inaccessible and fixed

Python's queue module provides thread-safe queues, suitable for multi-thread data delivery; 2. Queue() is a FIFO queue, LifoQueue() is a last-in first-out queue, and PriorityQueue() is dequeued according to priority; 3. In multi-threads, put() is enqueued and get() is dequeued, and task_done() and join() are used to ensure the completion of the task; 4. The producer-consumer model is a typical application, and the consumer needs to be notified to end with None signal. The program exits correctly after all tasks are completed.
