The sequence’s maximum element. If the sequence has no elements, returnsnil. Discussion In this example, an asynchronous sequence calledCounterproducesIntvalues from1to10. Themax()method returns the max value of the sequence. letmax=awaitCounter(howHigh:10).max()print(max??"none")// Prints...
The sequence’s maximum element. If the sequence has no elements, returns nil. Discussion This example finds the largest value in an array of height measurements. let heights = [67.5, 65.7, 64.3, 61.1, 58.5, 60.3, 64.9] let greatestHeight = heights.max() print(greatestHeight) // Prints ...

For string values, MAX is determined by which string is last in the collating sequence. If MAX is used as an analytic function and the window being evaluated contains no rows, MAX returns null. For more information, see Analytic Functions. Related Topics Windowed Queries Aggregate Functions ...
