Oliver Lee updated CALCITE-5430:
--------------------------------
Description:
Implementing IFNULL() for BIG_QUERY dialect
IFNULL(expr, null_result)
If {{expr}} evaluates to {{{}NULL{}}}, returns {{{}null_result{}}}. Otherwise,
returns expr. If {{expr}} doesn't evaluate to {{{}NULL{}}}, {{null_result}}
isn't evaluated.
[https://cloud.google.com/bigquery/docs/reference/standard-sql/conditional_expressions#ifnull]
example:
{{ifnull(null, 5)}} -> returns 5
{{ifnull(1,2)}} -> returns 1
