#### db_type: mongodb #### #### test_type: sda_non_repeatable_read_committed #### #### isolation: snapshot #### 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 T1 execute stmt: 't1.put(0, 0)' T1 start transaction success T1 execute stmt: 't1.get(0)' current_result: (0,0) *(1) expected_result: (0,0) (2) expected_result: (0,1) T2 start transaction success T2 execute stmt: 't1.put(0, 1)' T2 COMMIT transaction success T1 execute stmt: 't1.get(0)' current_result: (0,0) *(1) expected_result: (0,0) (2) expected_result: (0,1) T1 COMMIT transaction success T3 execute stmt: 't1.get(*)' current_result: (0,1) *(1) expected_result: (0,1) *(2) expected_result: (0,1) 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
