#### db_type: oracle #### #### test_type: sda_dirty_read #### #### isolation: serializable #### current_result: The query result of the current SQL statement. Each row of table is separated by a space, and the fields in each row are separated by commas expected_result: The expected result is the expected query result for each SQL that conforms to the serializability theory ----------rat_sda_dirty_read test prepare---------- Q0-T1 execute sql: 'DROP TABLE t1;' Q0-T1 execute sql: 'CREATE TABLE t1 (k INT PRIMARY KEY, v INT);' Q0-T1 execute sql: 'INSERT INTO t1 VALUES (0, 0);' Q0-T1 execute opt: 'COMMIT;' ----------rat_sda_dirty_read test run---------- Q1-T1 execute opt: 'BEGIN;' Q1 finished at: 2022-5-26 0:40:54:580:367 Q2-T1 execute sql: 'UPDATE t1 SET v=1 WHERE k=0;' Q2 finished at: 2022-5-26 0:40:54:622:329 Q3-T2 execute opt: 'BEGIN;' Q3 finished at: 2022-5-26 0:40:55:79:272 Q4-T2 execute sql: 'SELECT * FROM t1 WHERE k = 0;' current_result: (0,0) *(1) expected_result: (0,0) Q4 finished at: 2022-5-26 0:40:55:123:121 Q5-T1 execute opt: 'ROLLBACK;' Q6-T2 execute opt: 'COMMIT;' Q7-T3 execute sql: 'SELECT * FROM t1;' current_result: (0,0) *(1) expected_result: (0,0) Q7 finished at: 2022-5-26 0:40:56:193:503 Q8-T3 execute opt: 'COMMIT;' The current result is consistent with the [(1) expected_result] of serial scheduling Test Result: Avoid Reason: Data anomaly did not occur and the data is consistent
