Representative DataFrame

Expression family (Polars, PySpark, DataFusion), default parameters.

def impl(ctx: DataFrameContext) -> Any:
        result = _expr_filter(ctx, _hits(ctx), filter_code)
        if sort_spec:
            sort_cols, descending = _sort_parts(sort_spec)
            result = result.sort(sort_cols, descending=descending)
        if limit_spec:
            result = result.limit(int(limit_spec))
        return result.select(*select_spec.split(",")) if select_spec else result

Get the exact query for your run

The blocks above are representative. To get the precise statement a specific platform runs at a specific scale, substitute your own values:

from benchbox import ClickBench

bench = ClickBench(scale_factor=1.0)            # your scale factor
queries = bench.get_queries(dialect="datafusion")   # your platform's dialect; drop dialect= for native SQL
print(queries['Q20'])

For the DataFrame form:

from benchbox.core.query_catalog import get_dataframe_render

print(get_dataframe_render('clickbench', 'Q20', family="expression").source)  # or family="pandas"
