## arrayCount(\[func,\] arr1, …) {#array-count}
Returns the number of elements in the arr array for which func returns something other than 0. If ‘func’ is not specified, it returns the number of non-zero elements in the array.
Returns the number of elements for which `func(arr1[i], …, arrN[i])` returns something other than 0. If `func` is not specified, it returns the number of non-zero elements in the array.
Note that the `arrayCount` is a [higher-order function](../../sql-reference/functions/index.md#higher-order-functions). You can pass a lambda function to it as the first argument.
