HiRDB hasn't equivalents for RATIO_TO_REPORT function. SQLWays leaves it as is and adds message /* SQLWays: Could not convert 'RATIO_TO_REPORT' */.

Oracle:

select ratio_to_report(c3) over (partition by c1) from t;

HiRDB:

select ratio_to_report(c3) over (partition by c1) from t;
/* SQLWays: Could not convert 'ratio_to_report' */
