Roman commented on DRILL-4963:
------------------------------
Found similar case with different error:
Run query for first time:
{code:sql}
select subqueryudf(t1.first_name, t2.last_name) from cp.`employee.json` t1
inner join (select last_name, subqueryudf(first_name, last_name) as full_name
from cp.`employee.json`) t2 on subqueryudf(t1.first_name,
t1.last_name)=t2.full_name order by t1.employee_id limit 1;
{code}
Error: VALIDATION ERROR: From line 1, column 248 to line 1, column 249: Table
't1' not found
SQL Query null
And second time:
{code:sql}
select subqueryudf(t1.first_name, t2.last_name) from cp.`employee.json` t1
inner join (select last_name, subqueryudf(first_name, last_name) as full_name
from cp.`employee.json`) t2 on subqueryudf(t1.first_name,
t1.last_name)=t2.full_name order by t1.employee_id limit 1;
{code}

> Issues when overloading Drill native functions with dynamic UDFs
> ----------------------------------------------------------------
>
> Key: DRILL-4963
> URL: https://issues.apache.org/jira/browse/DRILL-4963
> Project: Apache Drill
> Issue Type: Bug
> Components: Functions - Drill
> Affects Versions: 1.9.0
> Reporter: Roman
> Assignee: Arina Ielchiieva
> Attachments: test_overloading-1.0-sources.jar,
> test_overloading-1.0.jar
>
>
> I created jar file which overloads 3 DRILL native functions
> (LOG(VARCHAR-REQUIRED), CURRENT_DATE(VARCHAR-REQUIRED) and
> ABS(VARCHAR-REQUIRED,VARCHAR-REQUIRED)) and registered it as dynamic UDF.
> If I try to use my functions I will get errors:
> {code:xml}
> SELECT CURRENT_DATE('test') FROM (VALUES(1));
> {code}
> Error: FUNCTION ERROR: CURRENT_DATE does not support operand types (CHAR)
> SQL Query null
> {code:xml}
> SELECT ABS('test','test') FROM (VALUES(1));
> {code}
> Error: FUNCTION ERROR: ABS does not support operand types (CHAR,CHAR)
> SQL Query null
> {code:xml}
> SELECT LOG('test') FROM (VALUES(1));
> {code}
> Error: SYSTEM ERROR: DrillRuntimeException: Failure while materializing
> expression in constant expression evaluator LOG('test'). Errors:
> Error in expression at index -1. Error: Missing function implementation:
> castTINYINT(VARCHAR-REQUIRED). Full expression: UNKNOWN EXPRESSION.
> But if I rerun all this queries after "DrillRuntimeException", they will run
> correctly. It seems that Drill have not updated the function signature before
> that error. Also if I add jar as usual UDF (copy jar to
> /drill_home/jars/3rdparty and restart drillbits), all queries will run
> correctly without errors.
