hust-hhb opened a new pull request, #31626:
URL: https://github.com/apache/doris/pull/31626
## Proposed changes
When using update command to set column value, if the column is sequence
column, the column '__DORIS_SEQUENCE_COL__' should also be set to the same
value.
Here is an example:
CREATE TABLE IF NOT EXISTS table1(
user_id bigint,
date1 date,
group_id bigint
)
UNIQUE KEY(user_id)
DISTRIBUTED BY HASH(user_id) BUCKETS 5 properties(
"function_column.sequence_col"='group_id',
"replication_num" = "1",
"in_memory"="false"
);
insert into table1 values(1,'20240131',100);
insert into table1 values(2,'20240131',100);
now select * from table , the result is
1 2024-01-31 100
2 2024-01-31 100
UPDATE table1 SET group_id=200;
now select * from table , the result is
1 2024-01-31 200
2 2024-01-31 200
insert into table1 values(2,'20240131',100);
now select * from table , the result is, which is wrong
1 2024-01-31 200
2 2024-01-31 100
