justinmclean opened a new issue, #8056:
URL: https://github.com/apache/gravitino/issues/8056
### What would you like to be improved?
The output of toString in
api/src/main/java/org/apache/gravitino/rel/expressions/FunctionExpression.java
is a little odd and outputs things in the form "func([a,b)]" when "func(a,b)"
would be expected.
Here are some tests:
```
@Test
public void testToStringWithArguments() {
FunctionExpression expr =
FunctionExpression.of("func", NamedReference.field("a"),
NamedReference.field("b"));
assertEquals("func(a, b)", expr.toString());
}
@Test
public void testToStringWithoutArguments() {
FunctionExpression expr = FunctionExpression.of("func");
assertEquals("func()", expr.toString());
}
```
### How should we improve?
Fix the output.
