Aitozi commented on PR #22363:
URL: https://github.com/apache/flink/pull/22363#issuecomment-1498810787
This PR does not support the partition column with nested type, due to it
has been limited in `SqlCreateTableConverter#verifyPartitioningColumnsExist`.
So the partition column should only work with the top level column now.
```
private void verifyPartitioningColumnsExist(Schema mergedSchema,
List<String> partitionKeys) {
Set<String> columnNames =
mergedSchema.getColumns().stream()
.map(Schema.UnresolvedColumn::getName)
.collect(Collectors.toCollection(LinkedHashSet::new));
for (String partitionKey : partitionKeys) {
if (!columnNames.contains(partitionKey)) {
throw new ValidationException(
String.format(
"Partition column '%s' not defined in the table
schema. Available columns: [%s]",
partitionKey,
columnNames.stream()
.collect(Collectors.joining("', '", "'",
"'"))));
}
}
}
```
