------------------------------------------------------------------------
I have tried to reproduce this bug but I could not, here is my attempt:
{code}
/** Test case for
* <a href="https://issues.apache.org/jira/browse/CALCITE-1188";>[CALCITE-1188]
NullPointerException{{monospaced text}} when extract is called on a NULL date
field</a>.
* /
@Test public void testExtractOnNullDateField(){
CalciteAssert.that()
.with(CalciteAssert.Config.FOODMART_CLONE)
.query("select extract (year from \"end_date\"), \"hire_date\",
\"birth_date\"\n" +
"from \"foodmart\".\"employee\"\n" +
"where extract (year from \"end_date\") in (1994, 1995, 1996)\n" +
"group by extract(year from \"end_date\"), \"hire_date\", \"birth_date\"
limit 10000")
.returns("");
}
{code}
All the suggested ingredients are there:
# number of items in WHERE-IN clause must be equal or more than two
# null value for _end_date_ column used in the extract (both in the select and
where clauses)
Any suggestion?
