--------------------------------------
Summary: JDBC with UNNEST not working
Key: CALCITE-5354
URL: https://issues.apache.org/jira/browse/CALCITE-5354
Project: Calcite
Issue Type: Bug
Components: core
Affects Versions: 1.32.0
Reporter: Ulrich Kramer
Adding the following unit test to {{JdbcAdapterTest.java}} will throw an
exception
{code:java}
@Test void testUnnest() {
CalciteAssert.model(FoodmartSchema.FOODMART_MODEL)
.query("SELECT * FROM \"store\" A\n" +
"NATURAL JOIN UNNEST(SELECT ARRAY[A.\"store_id\"])\n")
.runs();
} {code}
