--- toc_priority: 111 --- # groupUniqArray Syntax: `groupUniqArray(x)` or `groupUniqArray(max_size)(x)` Creates an array from different argument values. Memory consumption is the same as for the [uniqExact](uniqexact.md) function. The second version (with the `max_size` parameter) limits the size of the resulting array to `max_size` elements. For example, `groupUniqArray(1)(x)` is equivalent to `[any(x)]`.
