Value Retrieval Functions¶
SQL Function | Description |
|---|---|
tableName.compositeType.field | Returns the value of a field from a Flink composite type (e.g. Tuple, POJO) by name. |
tableName.compositeType.* | Returns the flattened representation of a Flink composite type (e.g. Tuple, POJO), converting each of its immediate subtypes into a separate field. In most cases, the fields in the flattened representation have similar names to the original fields, but with a $ separator (e.g. mypojo$mytuple$f0). |
