Apache calcite / jdbc Oracle

Hello all, I'm trying calcite avatica v1.16.0 which seems to be a very great tool. I tried with a postgresql database and that works very fine (I used the provided docker standalone server for my tests) Now, I'm trying with an oracle database (v19c) and like for postgresql, I'm using a doc

Re: Apache calcite / jdbc Oracle

That sounds like a bug in Avatica. I was not aware that in 'isWrapperFor(Class iface)', 'iface' had to be an interface, and had assumed the driver would just return 'false'. Can you please log it? A solution would be to create an interface in Avatica for AvaticaPreparedStatement. (It seems that t

bug in DelegatingScope?

Hi, I was looking at the validation code and at some point I saw that piece of code in DelegatingScope#fullyQualify: https://github.com/apache/calcite/blob/571731b80a58eb095ebac7123285c375e7afff90/core/src/main/java/org/apache/calcite/sql/validate/DelegatingScope.java#L309 for (; i > 0; i--

Re: Apache calcite / jdbc Oracle

I checked https://docs.oracle.com/javase/7/docs/api/java/sql/Wrapper.html#isWrapperFor(java.lang.Class), and it mentions interface in multiple places, but it doesn't say explicitly that it should throw if the provided argument is not an interface. And I guess Oracle driver chose to enforce this str

Re: Question of Calcite Dynamic Code Generation Feature

like Haisheng mentioned, it is certainly debuggable, although not as convenient as plain java code. my understanding is that, the java code generation is merely a demonstration of the physical plan implementation. there are all kinds of ways to implement the logical plan, java code is merely a `he
