moshap-firebolt opened a new pull request, #2404:
URL: https://github.com/apache/datafusion-sqlparser-rs/pull/2404
GoogleSQL allows an aggregate call to carry an inline `WHERE` filter, e.g.
`COUNT(* WHERE cond)`, `SUM(x WHERE cond)`, `ARRAY_AGG(x WHERE cond ORDER BY
y)`.
It is the in-argument spelling of the standard `AGG(expr) FILTER (WHERE
cond)`.
### Changes
- Add `FunctionArgumentClause::Where(Expr)`.
- Parse it in `parse_function_argument_list` for the `BigQuery` and `Generic`
dialects, before `ORDER BY` / `LIMIT` / `HAVING`.
- `Display` renders `WHERE <expr>`; span is computed from the predicate.
- New test `parse_aggregate_with_where_filter` in
`tests/sqlparser_bigquery.rs`.
