PR Review 🔍

⏱️ Estimated effort to review [1-5]	2, because the PR primarily involves refactoring and updating test cases, which are generally straightforward to review. The changes are well-documented and isolated to specific test files, reducing the complexity of the review.
🧪 Relevant tests	Yes
⚡ Possible issues	Possible Bug: The use of hardcoded passwords ('111' and '******') in test cases could be a concern if these patterns are replicated in production code or if the test environment is not properly isolated.
🔒 Security concerns	No

PR Code Suggestions ✨

Category	Suggestion	Score
Security	Use a stronger password for the create account statement to enhance security Consider using a more secure password for the create account statement to avoid potential security risks associated with using a simple password like '111'. test/distributed/cases/result_count/result_count.result [137] -/* cloud_user */create account bvt_result_count_test_case2 admin_name 'test_account' identified by '111'; +/* cloud_user */create account bvt_result_count_test_case2 admin_name 'test_account' identified by 'Str0ngP@ssw0rd!'; Suggestion importance[1-10]: 8 Why: Using a stronger password is crucial for security, especially for account creation statements in a database.	8
Best practice	Use drop account if exists to prevent errors if the account does not exist To ensure that the drop account statement does not fail if the account does not exist, consider using drop account if exists instead. test/distributed/cases/result_count/result_count.sql [108] -/* cloud_user */drop account bvt_result_count_test_case2; +/* cloud_user */drop account if exists bvt_result_count_test_case2; Suggestion importance[1-10]: 7 Why: Using drop account if exists is a best practice to avoid errors when the specified account does not exist, ensuring smoother operation and error handling in SQL scripts.	7
Enhancement	Add comments to explain the purpose of setting case names for better readability To improve readability and maintainability, consider adding comments to explain the purpose of the set @case_name statements. test/distributed/cases/zz_statement_query_type/result_count.result [2-15] +-- Set case name for case 1 set @case_name="case1"; select statement, result_count from statement_info where account="bvt_result_count" and statement not like '%mo_ctl%' and length(statement) > 0 and status != 'Running' and aggr_count < 1 order by request_at desc limit 50; ... +-- Set case name for case 2 set @case_name="case2"; select statement, result_count from statement_info where user="dump" and sql_source_type="cloud_user_sql" and status != 'Running' and statement like '%bvt_result_count_test_case2%' and aggr_count < 1 order by request_at desc limit 2; Suggestion importance[1-10]: 6 Why: Adding comments improves code readability and maintainability, which is beneficial for understanding the purpose of specific operations.	6
