----------------------------------------
Summary: SQL Calcite: Allow parameterless UDF calls without
parentheses
Key: IGNITE-29268
URL: https://issues.apache.org/jira/browse/IGNITE-29268
Project: Ignite
Issue Type: Improvement
Components: sql
Reporter: Kirill Tkalenko
Assignee: Kirill Tkalenko
Add {{allowUdfCallsWithoutParentheses}} to
{{{}CalciteQueryEngineConfiguration{}}}, defaulting to {{{}false{}}}. When
enabled, Calcite should accept all four queries for registered scalar and table
UDFs with no parameters.
{code:java}
SELECT my_udf;
SELECT my_udf();
SELECT * FROM TABLE(my_table_udf);
SELECT * FROM TABLE(my_table_udf());
{code}
If a bare name matches both a column and a scalar UDF, the column takes
precedence. Use my_udf() to call the function explicitly.
