### What problem does this PR solve?
Issue Number: close #xxx
Related PR: #xxx
Problem Summary:
Doris version 3.0.6
```sql
CREATE TABLE IF NOT EXISTS users(
user_id VARCHAR(32) NOT NULL,
event_time DATETIME NOT NULL,
type1 DECIMAL NOT NULL,
type2 DECIMAL NOT NULL,
val1 STRING NOT NULL,
val2 STRING NOT NULL,
val3 BIGINT NOT NULL
) ENGINE=OLAP
UNIQUE KEY(user_id, event_time, type1, type2)
AUTO PARTITION BY RANGE(DATE_TRUNC(event_time, 'hour')) ()
DISTRIBUTED BY HASH(user_id) BUCKETS 1
ROLLUP ( rlp_spacetime_collision(event_time, user_id, type1, type2) )
PROPERTIES (
"replication_allocation" = "tag.location.default: 1",
"function_column.sequence_col" = "event_time"
);
insert into users values(1,'2025-09-16 10:00:00',1,1,1,1,1);
select * from users;
[E-207]slot(id: 5, name: val2)'s nullable does not match column(tablet id:
-1, index: 9, name: __DORIS_SEQUENCE_COL__)
```
Doris versions 3.0.7 and later will not result in an error, this problem
still exists.
The reasons are as follows.
all `MaterializedIndexMeta` shared one `sequenceCol`
```java
public void setSequenceInfo(Type type, Column refColumn) {
this.hasSequenceCol = true;
this.sequenceType = type;
Column sequenceCol;
if (getEnableUniqueKeyMergeOnWrite()) {
// sequence column is value column with NONE aggregate type for
// unique key table with merge on write
sequenceCol = ColumnDef.newSequenceColumnDef(type,
AggregateType.NONE).toColumn();
} else {
// sequence column is value column with REPLACE aggregate type
for
// unique key table
sequenceCol = ColumnDef.newSequenceColumnDef(type,
AggregateType.REPLACE).toColumn();
}
if (refColumn != null) {
sequenceCol.setDefaultValueInfo(refColumn);
}
// add sequence column at last
fullSchema.add(sequenceCol);
nameToColumn.put(Column.SEQUENCE_COL, sequenceCol);
for (MaterializedIndexMeta indexMeta : indexIdToMeta.values()) {
List<Column> schema = indexMeta.getSchema();
schema.add(sequenceCol);
}
}
```
when init column `uniqueId`, base index sequence column unique id override
roullup index sequence column `uniqueId `
```java
public void initSchemaColumnUniqueId() {
maxColUniqueId = Column.COLUMN_UNIQUE_ID_INIT_VALUE;
this.schema.forEach(column -> {
column.setUniqueId(incAndGetMaxColUniqueId());
if (LOG.isDebugEnabled()) {
LOG.debug("indexId: {}, column:{}, uniqueId:{}",
indexId, column, column.getUniqueId());
}
});
}
```
then BE will make an incorrect judgment.
