ambition commented on CALCITE-2663:
-----------------------------------
sorry, I have two pull request, [PR
#913|https://github.com/apache/calcite/pull/913] based branch-1.16 and
[PR
#920|[https://github.com/apache/calcite/pull/913|https://github.com/apache/calcite/pull/920]]
based branch-1.17, so I modified PR #913 or PR #920, not modified PR I close
pull request.
I can fix parse return like:
{code:java}
CREATE OR REPLACE FUNCTION IF NOT EXISTS `X`.`UDF` AS
'org.apache.calcite.udf.TableFun.demoUdf'
('file:/path/udf/udf-0.0.1-SNAPSHOT.jar', 'file:/path/udf/logback.xml')
{code}
but original return is good to understand :
{code:java}
CREATE OR REPLACE FUNCTION IF NOT EXISTS `X`.`UDF` AS
'org.apache.calcite.udf.TableFun.demoUdf' USING
('file:/path/udf/udf-0.0.1-SNAPSHOT.jar', 'file:/path/udf/logback.xml')
{code}
> create function and drop function SQL statement
