…ectly ## Proposed changes For insert into values, we can write `\N` string to a column. ``` insert into t2 values(1, '"b"', 100); insert into t2 values(2, '\N', 100); insert into t2 values(3, '\\N', 100); mysql> select * from t2 where name is null; Empty set (0.03 sec) ``` But txn insert and group commit insert use stream load as the inner implementation, the `\N` means `null`, so the write result is not correct. ``` begin; insert into t2 values(1, '"b"', 100); insert into t2 values(2, '\N', 100); insert into t2 values(3, '\\N', 100); commit; mysql> select * from t2 where name is null; +------+------+-------+ | id | name | score | +------+------+-------+ | 3 | NULL | 100 | +------+------+-------+ 1 row in set (0.02 sec) ``` ## Further comments If this is a relatively large or complex change, kick off the discussion at [d...@doris.apache.org](mailto:d...@doris.apache.org) by explaining why you chose the solution you did and what alternatives you considered, etc... -- This is an automated message from the Apache Git Service.
