#### db_type: ob #### #### test_type: sda_intermediate_read_committed #### #### 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_intermediate_read_committed 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_intermediate_read_committed test run---------- Q1-T1 execute sql: 'BEGIN;' Q1 finished at: 2022-5-20 15:9:46:241:623 Q2-T1 execute sql: 'UPDATE t1 SET v=1 WHERE k=0;' Q2 finished at: 2022-5-20 15:9:46:245:571 Q3-T2 execute sql: 'BEGIN;' Q3 finished at: 2022-5-20 15:9:46:342:83 Q4-T2 execute sql: 'SELECT * FROM t1 WHERE k=0;' current_result: (0,0) (1) expected_result: (0,2) *(2) expected_result: (0,0) Q4 finished at: 2022-5-20 15:9:46:345:20 Q5-T2 execute opt: 'COMMIT;' Q5 finished at: 2022-5-20 15:9:46:345:962 Q6-T1 execute sql: 'UPDATE t1 SET v=2 WHERE k=0;' Q6 finished at: 2022-5-20 15:9:46:442:845 Q7-T1 execute opt: 'COMMIT;' Q7 finished at: 2022-5-20 15:9:46:445:253 Q8-T3 execute sql: 'SELECT * FROM t1;' current_result: (0,2) *(1) expected_result: (0,2) *(2) expected_result: (0,2) Q8 finished at: 2022-5-20 15:9:46:448:153 Q9-T3 execute opt: 'COMMIT;' Q9 finished at: 2022-5-20 15:9:46:449:250 The current result is consistent with the [(2) expected_result] of serial scheduling Test Result: Avoid Reason: Data anomaly did not occur and the data is consistent
