------------------------------------
Summary: Support BigQuery-style JSON_OBJECT invocation syntax
Key: CALCITE-6255
URL: https://issues.apache.org/jira/browse/CALCITE-6255
Project: Calcite
Issue Type: Improvement
Components: core
Affects Versions: 1.36.0
Reporter: Barry Kelly
Currently, Calcite has two styles for invoking JSON_OBJECT:
{{ JSON_OBJECT(KEY 'foo' VALUE 'bar', KEY 'foo2' VALUE 'bar2')}}
and:
{{ JSON_OBJECT('foo' : 'bar', 'foo2' : 'bar')}}
However,
[BigQuery|https://cloud.google.com/bigquery/docs/reference/standard-sql/json_functions#json_object]
uses a lighter-weight syntax resembling the MAP<> constructor, with an even
numbered argument list where every odd item is a key and the following even
item is a value:
{{ JSON_OBJECT('foo', 'bar', 'foo2', 'bar2')}}
With the objective of syntax compatibility with BigQuery, the simplest change
to the grammar is to allow ',' as well as ':' for separating key/value pairs in
the invocation.
