------------------------------------
Summary: OBJECT_OF function's type don't get inferred correctly
during comparison
Key: FLINK-38083
URL: https://issues.apache.org/jira/browse/FLINK-38083
Project: Flink
Issue Type: Sub-task
Reporter: Ramin Gharib
Whenever we compare a structure type in the example below with one that was
created through the `OBJECT_OF` function, the types don't match correctly.
{code:java}
public static class Type1 {
public Integer a;
public String b;
public static class Type1Constructor extends ScalarFunction {
public Type1 eval(Integer a, String b) {
final Type1 t = new Type1();
t.a = a;
t.b = b;
return t;
}
}
// getter and setters
}
{code}
For the
{noformat}
ROW(42, "Bob"){noformat}
In SQL and TableAPI, the returned type of `Type1Constructor(f0, f1)` would be a
{code:java}
"STRUCTURED<'type1class', `a` INT, `b` STRING>" {code}
where as the OBJECT_OF(Type1.class, "a", f0, "b", f1) would yeeled:
{code:java}
"STRUCTURED<'type2class', `a` INT NOT NULL, `b` CHAR(3) NOT NULL>" {code}
This will cause failure in equal expressions.
