URL: https://github.com/apache/iceberg-python/issues/1937
### Apache Iceberg version
0.9.0 (latest release)
### Please describe the bug 🐞
Hi, thanks for writing `pyiceberg`.
The bug is pretty described in the title: `table.scan(row_filter="x IN (0,
1)")` does not include the values for which `x=0` when `x` is a `DoubleType`
and a partition column.
Here is a reproducer:
```bash
pip install pyiceberg[sql-sqlite,pyarrow]
```
```python
from pathlib import Path
from tempfile import TemporaryDirectory
import pyarrow
from pyiceberg.catalog.sql import SqlCatalog
from pyiceberg.schema import Schema
from pyiceberg.transforms import IdentityTransform
from pyiceberg.types import DoubleType, NestedField
from pyiceberg.partitioning import PartitionSpec, PartitionField
schema = Schema(
NestedField(field_id=1, name="x", field_type=DoubleType()),
NestedField(field_id=2, name="y", field_type=DoubleType()),
)
partition_spec = PartitionSpec(PartitionField(source_id=1, field_id=1001,
transform=IdentityTransform(), name="x"))
with TemporaryDirectory() as tmpdir:
catalog = SqlCatalog(
"local",
uri=f"sqlite:///{tmpdir}/catalog.db",
warehouse=f"file://{tmpdir}/warehouse",
)
catalog.create_namespace("test")
table = catalog.create_table(
"test.test", schema=schema, partition_spec=partition_spec
)
data = pyarrow.table(
{
"x": [0.0, 1.0, 2.0],
"y": [0.0, 0.0, 0.0],
}
)
table.overwrite(data)
print("=== no filter ===")
print(table.scan().to_arrow())
print("=== x IN (0) ===")
print(table.scan(row_filter="x IN (0)").to_arrow())
print("=== x IN (0, 1, 2) ===")
print(table.scan(row_filter="x IN (0, 1, 2)").to_arrow())
```
Output:
```
/tmp/tmp.l2MLQFjC7C-05duO9h5/lib/python3.13/site-packages/pyiceberg/table/__init__.py:686:
UserWarning: Delete operation did not match any records
warnings.warn("Delete operation did not match any records")
=== no filter ===
pyarrow.Table
x: double
y: double
----
x: [[0],[1],[2]]
y: [[0],[0],[0]]
=== x IN (0) ===
pyarrow.Table
x: double
y: double
----
x: [[0]]
y: [[0]]
=== x IN (0, 1, 2) ===
pyarrow.Table
x: double
y: double
----
x: [[1],[2]]
y: [[0],[0]]
```
I expect output for `x in (0, 1, 2)` to match that of the `no filter` scan.
Note that I could not reproduce when `x` is a `LongType` instead of a
`DoubleType`.
