RelToSqlConverter NullPointerException
hi team,
I met a NullPointerException when I used calcite 1.24.0 to convert a
relNode to sqlNode.
The trace:
java.lang.NullPointerException
at java.base/java.util.Objects.requireNonNull(Objects.java:221)
at
org.apache.calcite.rel.rel2sql.RelToSqlConverter.result(RelToSqlConverter.java:152)
at
org.apache.calcite.rel.rel2sql.SqlImplementor.result(SqlImplementor.java:454)
at
org.apache.calcite.rel.rel2sql.SqlImplementor$Builder.result(SqlImplementor.java:1822)
at
org.apache.calcite.rel.rel2sql.RelToSqlConverter.visit(RelToSqlConverter.java:392)
at server.TestRelToSqlConverter.test(TestRelToSqlConverter.java:84)
Attched file is a junit5 test case,you can repeat the issue with this code.
Maven configuration:
<dependency>
<groupId>org.apache.calcite</groupId>
<artifactId>calcite-core</artifactId>
<version>1.24.0</version>
</dependency>
<dependency>
<groupId>org.apache.commons</groupId>

<version>2.7.0</version>
</dependency>

<version>42.2.12</version>
</dependency>

Hi tonytao
In your code, you connect pg, can you reproduce this
in RelToSqlConverterTest?
Regards!

Thanks for reporting this. Please file a JIRA case with the necessary
information.
Also it would be helpful if you could refactor your test case as part of
RelToSqlConverterTest [1].
Best,
Stamatis
