#### db_type: oracle #### #### test_type: dda_write_skew_pred_insert #### #### isolation: read-committed #### 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 ----------iat_dda_write_skew_pred_insert 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 opt: 'COMMIT;' ----------iat_dda_write_skew_pred_insert test run---------- Q1-T1 execute opt: 'BEGIN;' Q1 finished at: 2022-5-26 0:40:47:664:468 Q2-T1 execute sql: 'SELECT * FROM t1 WHERE v<2; ' current_result: null *(1) expected_result: null (2) expected_result: (0,1) Q2 finished at: 2022-5-26 0:40:47:710:635 Q3-T2 execute opt: 'BEGIN;' Q3 finished at: 2022-5-26 0:40:48:164:564 Q4-T2 execute sql: 'SELECT * FROM t1 WHERE v>2;' current_result: null (1) expected_result: (1,3) *(2) expected_result: null Q4 finished at: 2022-5-26 0:40:48:210:944 Q5-T2 execute sql: 'INSERT INTO t1 VALUES (0, 1);' Q5 finished at: 2022-5-26 0:40:48:290:811 Q6-T1 execute sql: 'INSERT INTO t1 VALUES (1, 3);' Q6 finished at: 2022-5-26 0:40:48:705:495 Q7-T1 execute opt: 'COMMIT;' Q8-T2 execute opt: 'COMMIT;' Q9-T3 execute sql: 'SELECT * FROM t1 ORDER BY k;' current_result: (0,1) (1,3) *(1) expected_result: (0,1) (1,3) *(2) expected_result: (0,1) (1,3) Q9 finished at: 2022-5-26 0:40:49:295:251 Q10-T3 execute opt: 'COMMIT;' Test Result: Anomaly Reason: Data anomaly is not recognized by the database, resulting in data inconsistencies
