anyLast
Selects the last encountered value of a column.
:::warning
As a query can be executed in arbitrary order, the result of this function is non-deterministic.
If you need an arbitrary but deterministic result, use functions min
or max
.
:::
By default, the function never returns NULL, i.e. ignores NULL values in the input column.
However, if the function is used with the RESPECT NULLS
modifier, it returns the first value reads no matter if NULL or not.
