Hey Xiabo,
You can do this, however it is easiest to do from the "FrameworkConfig"
object, like this:
import org.apache.calcite.tools.FrameworkConfig
// Need to set case-sensitive to false, or else it tries to
// look up capitalized table names and fails
//
// IE: "EMPS" instead of "emps"

Apologies for the delay in replying
This makes things clear and seems obvious now that you point it out.
Thank you, Justin and Julian =)
Let me ask another question (if I may) that I am struggling to phrase
easily.
So with GraphQL, you might have a query like:
- "Get houses"
- "For each house ge
Correlated ARRAY sub-query?

Forgive my ignorance/lack of experience
I am somewhat familiar with the ARRAY() function, but not sure I know the
term "correlated"
Searching the Calcite codebase for uses of "correlated" + "query", I found:
https://github.com/apache/calcite/blob/1d4f1b394bfdba03c5538017e12ab2431b137ca9/core/src/
Nevermind, this is a standard term not something Calcite-specific it seems!

Hi Gavin,
Thanks for your help,
the defaultSchema(SchemaPlus defaultSchema) method need a SchemaPlus which only
can be get after a connection is opened, but we want to set a target subschema
such as RelfectiveShcema to be the default one, and we guess the default schema
setting operation shoul
You can create an empty root schema, add a ReflectiveSchema, and then set
this as the default schema:
val rootSchema: SchemaPlus = Frameworks.createRootSchema(true)
val hrReflectiveSchema = ReflectiveSchema(HrSchema())
rootSchema.add("hr", hrReflectiveSchema)
Frameworks.newConfigBuilder()

After ~5 hours, I think I may have made some progress =)
I have this, which currently works. The problem is that the nested columns
don't have names on them.
Since I need to return a nested "Map", I have to figure out
how to convert this query into a form that gives column names.
But this is stil
Ah wait nevermind, got excited and spoke too soon. Looking at it more
closely, that data isn't correct.
At least it's in somewhat the right shape, ha!
