Hi Dan,
Yes, I want to add some udf defined in Spark.
Initially, I had:
SqlLibraryOperatorTableFactory.INSTANCE.getOperatorTable(
SqlLibrary.STANDARD,
SqlLibrary.SPARK
)
but it looks like some functions are not available, in my case it was:
* sha2 (not defined)
* from_unixtime (not
Hi Guillaume, are you using your own udf and some functions in
SqlStdOperatorTable at the same time? If yes, SqlOperatorTables#chain is the
right way to organize multiple SqlOperatorTable.
Best,
Dan Zou

I found the solution here:
https://stackoverflow.com/questions/58268828/apache-calcite-registering-udfs-for-use-in-relbuilder
The idea is to use
`SqlOperatorTables.of`` to register a list of SqlFunction
then use `SqlOperatorTables.chain` to join it with
`SqlStdOperatorTable.instance()`
On Mon,
ah this is Scala, it's a bit shorter to write

Hi All,
How can we register a custom udf? I found some solutions on Stackoverflow
but they are out of date (
https://stackoverflow.com/questions/44147819/adding-a-user-defined-function-to-calcite
)
So far what I have:
// top level class
class CustomUdf {
def foo(in: Double): Double = in + 1
}
