Description
The following query fails:
@Test
def testProcessTimeInnerJoin(): Unit = {
val env = StreamExecutionEnvironment.getExecutionEnvironment
val tEnv = TableEnvironment.getTableEnvironment(env)
env.setStateBackend(getStateBackend)
StreamITCase.clear
env.setParallelism(1)
val sqlQuery = "SELECT t2.a, t2.c, t1.c from T1 as t1 join T2 as t2 on t1.a = t2.a and t1.nullField = t2.nullField and " +
"t1.proctime between t2.proctime - interval '5' second and t2.proctime + interval '5' second"
val data1 = new mutable.MutableList[(Int, Long, String)]
data1.+=((1, 1L, "Hi1"))
data1.+=((1, 2L, "Hi2"))
data1.+=((1, 5L, "Hi3"))
data1.+=((2, 7L, "Hi5"))
data1.+=((1, 9L, "Hi6"))
data1.+=((1, 8L, "Hi8"))
data1.+=((1, 8L, "Hi8"))
val data2 = new mutable.MutableList[(Int, Long, String)]
data2.+=((1, 1L, "HiHi"))
data2.+=((2, 2L, "HeHe"))
val t1 = env.fromCollection(data1).toTable(tEnv, 'a, 'b, 'c, 'proctime.proctime)
.select('a, 'b, 'c, 'proctime, Null(Types.LONG) as 'nullField)
val t2 = env.fromCollection(data2).toTable(tEnv, 'a, 'b, 'c, 'proctime.proctime)
.select('a, 'b, 'c, 'proctime, 12L as 'nullField)
tEnv.registerTable("T1", t1)
tEnv.registerTable("T2", t2)
val result = tEnv.sqlQuery(sqlQuery).toAppendStream[Row]
result.addSink(new StreamITCase.StringSink[Row])
env.execute()
}
It leads to:

Seems to be a Calcite bug, but we have to investigate this first. Replacing Null(Types.LONG) with a value works.
