Jia-Xuan Liu updated CALCITE-5245:
----------------------------------
Description:
Access an element of array in BigQuery should invoke `ORDINAL`(1-based) or
`OFFSET`(0-based) operator for the index. See [BigQuery Accessing array
elements|https://cloud.google.com/bigquery/docs/reference/standard-sql/arrays#accessing_array_elements].
For example:
{code:sql}
SELECT ARRAY[1,2,3][ORDINAL(1)]
{code}
In Calcite, we access an array element using a common way like `array_expr[1]`.
When we try to convert a Calcite SQL to a BigQuery SQL, `BigQuerySqlDialect`
should use the BigQuery
