Description
Describe the bug
- When the column of the target table are different from the columns of the source table, the generated column are lineage, and the column of the target table are still generated from the source table
SQL
Paste the SQL text here. For example:
insert into db.tbl_z select * from db.tbl_x API (Application Programming Interface): provide the python code you're using and the output.
For example:
providers = generate_metadata_providers(
{
"db.tbl_x": ["id", "a", "b"],
"db.tbl_z": ["pk", "s", "t"],
}
)
@pytest.mark.parametrize("provider", providers)
def test_select_single_table_wildcard(provider: MetaDataProvider):
sql = """insert into db.tbl_z
select *
from db.tbl_x
"""
assert_column_lineage_equal(
sql,
[
(
ColumnQualifierTuple("id", "db.tbl_x"),
ColumnQualifierTuple("id", "db.tbl_z"),
),
(
ColumnQualifierTuple("a", "db.tbl_x"),
ColumnQualifierTuple("a", "db.tbl_z"),
),
(
ColumnQualifierTuple("b", "db.tbl_x"),
ColumnQualifierTuple("b", "db.tbl_z"),
),
],
metadata_provider=provider
)Expected behavior
{(db.tbl_x.b, db.tbl_z.t), (db.tbl_x.id, db.tbl_z.pk), (db.tbl_x.a, db.tbl_z.s)}
actual:
{(db.tbl_x.b, db.tbl_z.b), (db.tbl_x.id, db.tbl_z.id), (db.tbl_x.a, db.tbl_z.a)}
