-----------------------------------------
Summary: User-defined functions should be able to use custom java
arguments
Key: CALCITE-455
URL: https://issues.apache.org/jira/browse/CALCITE-455
Project: Calcite
Issue Type: Bug
Affects Versions: 0.9.1-incubating
Reporter: Vladimir Sitnikov
Assignee: Julian Hyde
Attachments: custom_argument_type_test.diff
Calcite fails to recognize function that accepts custom java class.
For instance, when trying to evaluate {{my_unwrap(my_wrap(42))}} I get
{{SqlValidatorException: No match found for function signature
MY_UNWRAP(<JavaType(class net.hydromatic.optiq.test.JdbcTest$MyIntWrapper)>)}}
{code:java}
/** Un-wraps a user-defined wrapper into int */
public static class MyUnWrapFunction {
public static int eval(MyIntWrapper v) {
return v.v;
}
}
/** User-defined wraper to check custom datatype support. */
public static class MyIntWrapper {
public final int v;
public MyIntWrapper(int v) {
this.v=v;
}
}{code}
{noformat}
java.lang.RuntimeException: exception while executing [select
"adhoc".my_unwrap("adhoc".my_wrap(42)) as p from "adhoc".EMPLOYEES]
