Ordering WITHIN GROUP

Applies to ✅ Open Source Edition   ✅ Express Edition   ✅ Professional Edition   ✅ Enterprise Edition

Some aggregate functions allow for ordering their inputs to produce an ordered output. These aggregate functions allow for specifying a mandatory WITHIN GROUP (ORDER BY ..) clause after the function.

Standard SQL talks about "ordered set aggregate functions" which come in three flavours

  • Hypothetical set functions: Functions that check for the position of a hypothetical value inside of an ordered set. These include RANK, DENSE_RANK, PERCENT_RANK, CUME_DIST.
  • LISTAGG, which is inconsistently using the WITHIN GROUP syntax, as it is used to order the output of the function, and isn't mandatory in all dialects.
