URL: https://github.com/apache/beam/pull/12054#issuecomment-650415147
Thanks for patching the precision fix! The only remaining issue revealed
from internal tests is that during `CAST` operation time microsecond-precision
could be lost. Could you please add the following unit test to the end of the
new test lists? If you have time you can look into it a bit more to see if
there is a quick fix. Otherwise feel free to create a new JIRA to track the
problem and then ignore the test.
```
@Test
public void testCastBetweenTimeAndString() {
String sql =
"SELECT CAST(s1 as TIME) as t2, CAST(t1 as STRING) as s2 FROM "
+ "(SELECT '12:34:56.123456' as s1, TIME '12:34:56.123456' as
t1)";
ZetaSQLQueryPlanner zetaSQLQueryPlanner = new
ZetaSQLQueryPlanner(config);
BeamRelNode beamRelNode = zetaSQLQueryPlanner.convertToBeamRel(sql);
PCollection<Row> stream = BeamSqlRelUtils.toPCollection(pipeline,
beamRelNode);
PAssert.that(stream)
.containsInAnyOrder(
Row.withSchema(
Schema.builder()
.addLogicalTypeField("t2", SqlTypes.TIME)
.addStringField("s2")
.build())
.addValues(LocalTime.of(12, 34, 56, 123456000),
"12:34:56.123456")
.build());
pipeline.run().waitUntilFinish(Duration.standardMinutes(PIPELINE_EXECUTION_WAITTIME_MINUTES));
}
```
